I have 3 devices under my car connected to my exhaust, but I dont know what they are or what to do about them?

I have 3 devices under my car connected to the exhaust system. Im unsure about what they are, what I can do about them, or how I can modify these to make the car louder,lighter,and less restricted. The car is not broken and doesnt need repair, this is about modding it. My biggest concern is the last device (3rd picture), because it is big, and most likely heavy. I know the exhaust system will restrict the engine, I also know that the exhaust system has a muffler and a catalytic converter. So my question is   What is this device in the back? How can it be removed/bypassed/replaced/modified to be louder lighter and less restricting? And if I cant do anything with it, what can I do? (the devices are in order from closest to engine to farthest)

In theory, can you hook a turbocharger to the end of another turbo to make the 2nd turbocharger spin at a faster rate?

I need to know if you can hook a turbo to the output of another turbo so produce a faster rate and air flow, not for car so dont worry im not going to blow up my engine. Also wondering a couple other things car parts related while I am at it, how much force does it take to spin an alternator when its "on". i know that when the car is not on it free spins but once it is and does not have belt hooked to it it is hard if not impossible to turn by hand. thanks for the help.

Simple homemade clutch for a flywheel toy?

I love those old flywheel toy cars and pump tops, but they are getting too rare to disassemble and I'd love to know how they work! I understand the push part, like in a push drill. What I can't seem to find is how to get the wheel faster and faster with repeated pumps. There must be some sort of clutch that somehow doesn't need to match speed with the spinning wheel, and it must be simple, or they wouldn't have used it in those (originally) inexpensive old toys, I do remember that there was no ratchet noise. But I can't figure it out. I know this sort of thing used to be quite common, but I'm drawing a blank on the internet. Any help will be appreciated! Many thanks!

Wind Powered Quad-Cart

I haven't seen anything this on here so I thought I'd step up. Engineers (or anyone who fancies themselves A DIYer) I found a few days back I little some very interesting Wind Powered Rides...six-or-seven-ways-wind-powers-vehicles OK so we know it CAN be done, but can it be done by a DIYer? OK here's my concept, Design and shape are optional but basic components are such: Take a pair of multi-speed Bicycles, their gearing will be the basic propulsion for this vehicle. Take one of the "bikes" and hook up a prop where the pedals "where" and set the wheel output to be higher then the prop speed, this should take care of the foreward movement once going. Now for the initial starting power (Bike 2), this can either be by petal, or by electric (solar/battery- up to you) But the basis for this whole thing is simple energy transfer, if the moving air over the prop causes the drive wheels to go, and by having them geared higher, the vehicle SHOULD move faster the faster you go ..Right? Can I get some math to back this up? it sounds like it would work.

Yes, there is some co2 in my exhaled breath, but it is mostly  n2,  and  o2.  I would hav expected the n2 and o2 to leak out more quickly, being smaller molecules. So whatzup wit dat?

Thinking about overclocking some of my 18v power tools.  I can adapt 24v battery packs to fit into them.  Obvious advantage is they will run faster and should run longer with the extra power.  My only concern is can this damage the motors?  I think the only real risk is overheating but it I take steps to avoid that would everything else be okay?  I've also considered hooking two battery packs together to run an 18v saw at 36 volts.

Quadropropellor concept

Last night I had this dream about a bizarre helicopter that used a simple but unique form of a propeller.  Conceptually, I see no reason why it should not work... but I'm not sure if it would be any better or more efficient than a typical propeller.  The idea is that the geared propellers rotate at the tips of the main rotor as it spins.  The outside ring is fixed such that as the central propeller spins, each of the out side disc spin creating lift from both the central propeller as well as each of the four outside propellers.  Because the geared wheels will spin faster than the central rotor, theoretically it might produce more lift than a single propeller (maybe).  I would like to hear other people's thoughts on the concept.  If someone has a 3D printer, it should be relatively simple to make and test.

What I need to represent is the more the bellows are pumped the more the "embers" will glow. Im thinking a turbine tachometer that leads to an LED driver set to display as Bar so the faster the turbine spins the more LEDS are lit, or they trigger a series of LEDs to light (this thing has to get pretty bright not sure one LED per step will do it. Trouble is im good with the theory and pretty good with the practical its just the technical that is letting me down.

First Solar Powered Speedboat

Via The UberReview"It is not too often that we associate solar-powered with anything fast and or furious, but perhaps it is time that we start. The Czeers MK1 is a 10-meter vessel covered in photovoltaic cells that is capable of hitting speeds of up to 30 knots (55.5 km/ph to you non-nautical folks out there). While there are certainly faster boats on the water, those tend to use obscene amounts of fuel. The solar-powered Czeers MK1 is naturally going to be a lot quieter than its gas guzzling cousins, which would make it great for sneaking up over fish (though there is limited space to put them if you catch them. I would like to see a similar model with little bit more space for passengers, even if it did mean sacrificing some speed. Speedboats are so limited in what they are able to do, but if this had a little extra space, it could do so much more."

Power Banks vs. ac wall outlets

I've observed in many power banks, that they charge up my phone a LOT quicker than a conventional ac adapter plugged into a wall socket. Why is this so? Many of my friends share the same observation. I'm building a simple power bank myself, and I want to make sure I can enjoy this feature when I use it too. I plan to use this instructable as a guideline with some modifications: https://www.instructables.com/id/Rechargeable-homemade-Power-Bank-super-Easy/ I'll be using four 3.7V batteries in parallel and stepping it up with a step up converter, so that the mAh value gets added up (forgive me if I'm wrong, but I believe mAh adds up when batteries are in parallel). Will this arrangement give me faster charging times like the power banks available in the market? Is it a safe circuit? Please suggest as I am eager to build this :) Thanks in advance :)

Not sure where to find a 60 to 120 rpm AC motor

I'd like to add a small motor to a hand cranked coffee grinder (Hario Skerton Coffee Grinder).  It's conical burr style grinder that produces a consistent particle size (much more so than the mini blender, whirlly style grinder).  I'll expand on why that's important when I build the thing.   My problem is that is takes 10 minutes or so to grind enough coffee for two people. I'd like to put a motor on it.  I tried spinning it with a battery powered drill, but the RPMs were too high.  The burr spun faster than coffee beans could feed.  I'd like a motor in the 60 to 120 rpm range.  I still need to determine the torque required.  Additionally, I'd like to plug this right in to a 110 outlet.  Does anyone have a suggestion on an appliance I could scavenge or the type of motor I should look to buy?   Thanks, Mike

Is this the right way to wire an old, one capacitor washing machine motor ?

I actually have an old Brandt 556T washing machine, and I'm trying to replace the internal mechanical program with an arduino some electronics. Actually I'm trying to directly run the motor at it's both speeds, and both directions. So, the motor is a Selni V689, and I also have another motor laying around. It's a Selni V604. The two of them seems to be using the same wiring. So, for the moment I'm using the older one (the V604) to experiment. After some googling, I understood this kind of motor uses a single capacitor to select the direction of the rotor, and it enables the motor to start without help. We can  wire it without the capacitor, and spin it manually to start it, or use the capacitor to start it properly. So, I ended up with the schema linked here. It seems to be working, except for the old V604 which, in second speed, runs faster in one direction that the other... But for the V689, it seems to be okay. I need to ensure that my wiring schema is really ok, then I'll try to use as few relays as possible to be able to fully control this motor with 3.3/5V logic. If anyone can help me confirm that, I'll really appreciate it ! Thank you guys ! NB: I firstly thought there was a problem with the power consumpsion of those motors, but I was wrong, it's fine.

Camera Stabilizer (Physics related)

I had an idea for a camera stabilizer a while ago which involves some basic rules of physics. I've done some thinking on it and I can't seem to figure out if it would really work or not. It involves two principles: 1.) Torque (t=f*d) 2.) Inertia (p=m*v) ---- The idea is to combine a gimbal design found on camera "gliders" like these: -Commercial product: http://www.bhphotovideo.com/c/product/521721-REG/Steadicam_MERLIN_Merlin_Camera_Stabilizing_System.html -Homemade design: http://www.diycamera.com/stabiliser/index.html ...with some sort of see-saw to counter the effects of up-and-down motion.  Ignoring the fact that this might be somewhat hard to hold such a thing, I just want to know if this would work. ---- Any balanced see-saw will have an equal amount of torque on either side of the pivot point. Therefore, a balanced see-saw will work with 500g hung 10cm from either side of the pivot point, OR 750g 5cm from one side and 250g 15cm from the other side (750*5=3750; 250*15=3750).  With this concept, I thought of designing this part of the stabilizer like a small camera jib (http://en.wikipedia.org/wiki/Jib_(camera)). That is, the camera on one end with a counterweight on the other. The pivot point would have a handle or some kind of vehicle mount on it.  The stabilization occurs (or so I'm thinking) because of inertia. Inertia=mass*velocity. So, when the pivot point (the handle) moves up or down, one of the sides of the see saw should move up faster than the other. The side that moves up slower (the longer side of the see saw, I'm thinking) should have the camera mounted to it.  ---- Is there a flaw somewhere in my thinking? THE QUESTION: Would both sides of an uneven length, balanced see-saw move up at the same time when the pivot point is moved up or down? I'm not really sure and I'd like to hear your input.

What 3D printers can do... and what they can't

3D printers have seen insane amounts of attention in the past year with lots of stories coming out about how amazing they are. How they can make replacement parts for anything that breaks. How they’ll revolutionize manufacturing. How everyone will have one and they’ll do everything that you need ever. Long story short, 3D printers are pretty amazing, but they aren’t quite the miracle on a stick that the hype is pushing them to be. So let’s sift through and see what there really is to get excited about right now. Consumer 3D printers AKA what most people will be using The 3D printing that’s available to consumers right now is fused deposition modeling or FDM. These printers build up a model layer by layer by extruding ABS or PLA into the build area. It’s basically a much fancier version of a glue gun. A tiny glue gun controlled by a computer, that is. These 3D printers typically run $1k - $2k, but smaller ones can be had for as little as $200. The MakerBot Replicator 2 is the most popular printer of this kind, but there are dozens of others to choose from as well. With some fiddling and work you can pretty much print any shape that fits inside the build volume. So if the printer can fit it, you can make it. That’s simplifying it a bit (OK, a lot), but that’s the idea, and it’s a very cool idea. After some practice you can learn how to design new things like jewelry, ornaments, or toys. Since everything is printed out you can customize any piece that you’d like. Take a couple hours to learn 123D Design and you’ll start to have new things to print out. That’s the power of 3D printing right there. You can quickly go from an idea to a design and then to reality. Your skills in making things by hand don’t matter here. This is why it’s so amazingly helpful to use a 3D printer for prototyping your ideas. I recently worked on a flash drive case and the first model took about 2 minutes to design. After that it was about 15 minutes to print out on a Replicator 2. Then I tested it and adjusted the design for another print. I repeated the process a few times and within 2 hours I had a file that I was happy with. This is even better considering that I only spent about 20 minutes of those 2 hours actively working. The rest was spent on other non-related work. All about the materials So that’s the power of 3D printing. With services like 3D Creation Systems you can upload your file and get it printed on much fancier machines with better resolution. There’s no immediate gratification, but you still get a high-quality print quickly and access to more materials. Even with this expanded selection of printing materials, it’s still a very limited selection. If we were just to look at all the plastics out there we’d be here for days. There are thousands of them and that’s just plastics. There’s also wood and metal and more beyond that. Each different material in this insanely huge selection has a different quality to it. I’ve seen countless people print out items in ABS or PLA and complain about how their printer must not be working since the printed piece doesn’t work like the original. But of course we can’t recreate every item out there with a couple kinds of plastic. It's about using 3D printing with other tools The key forward in using 3D printing is to use it as an amazing new tool of forming great pieces to work alongside all the other great items and materials out there. Why bother making a weak spring out of plastic when you can drop in a metal spring? So 3D printing isn’t everything, but it can be used alongside most everything. It can get us where we want to go so much faster than before it’s ridiculous. But it’s still not the miracle on a stick, not the only tool we’ll ever need from here on out. When the hype dies down we won’t be looking on at amazement at something being 3D printed, we’ll be looking at lots of awesome new things that were made faster with the help of 3D printing. And that is going to be incredible.

Nylon and substitutes on a cold bed

It's been some time and I made progress with Nylon. Aldi had some cheap craft glue with methanol as the solvent - this stuff works great for PLA, ABS AND Nylon. The common problem with nylon is that it has no real adhesion to anything, except cardboard and bakelite. Cardboard makes a clean up nightmare and bakelite is not always easy to find, especially not the right type. So I tried various glues, paints and primers but none was really suited for all printing needs. And the cleanup of the bed is imoprtant too as I did not want to spend hours scrubbing with acetone or similar nasty solvents. After the first great succes with the clear Aldi craft glue I checked the local 2$ shops and carft stores and found similar glueswith methanol as a solvent. Since not everyone is lucky enough to get these specials I will tell you what to look out for if you try clear craft glue: Don't buy anything that can be cleaned up with water - you want methanol or ethanol as the solvent in the glue! Do a test with the glue on something that usually does not bind well to cheap glue, like glass and blister packs. Let the glue dry and peel it off - it should be a clear film that is quite strong and barely streches when you pull it. It almost feels like hard paper. All good so far? Check if the nylon, pla or abs really sticks to it: Spread a very thin layer on a piece of cardboard and let dry. Add another, thicker layer and let dry again. Now hold it under your nozzle and extrude a bit of filament while moving the cardboard around. Let cool and check how good it sticks. In a perfect world the cool plastic should peel the papaer off with the glue. Time to prepare your print bed the same way and to start printing ;) Just use a very thin first layer and for the first layer much lower speeds than usual. I print nylon with 60mm/s and the first layer at just 25mm/s, any faster and the first layer does not look right. ABS and PLA are much more forgiving here.

Where is the induction kettle or hot water system?

No modern kitchen these days is complete without at least a single induction cooktop.Convient to even place on the table to keep things warm but also nice to have 4 or 6 "hotplates" to cook on that are actually not getting hot at all.When it comes to efficiency induction cooking tops all others as no heat is wasted.Which brings me to the point...A single cooktop goes now often for well under 50 bucks.Although the base might end up slightly higher than a normal kettle I fail to see why we don't have induction kettles in our kitchen.Why wait 12 minutes to have the thing boil if you can do it cheaper and faster?Way more convinient too as there is no pesky contacts and heating elements anymore, no failure due to leaks either...But what really got me wondering is the hot water systems or heating options like prefered in Europe.Here you have a central "boiler" so to say and water circulates through valves into finned radiators, usually located under windows.We have oil filled radiators of this kind as free standing units that are now being phased out because they waste too much energy with their heating elements.Same story for just hot water :(On demand systems are getting more popular now outside Europe but still the common solution is to have a few hundret liters of water in a tank that is kept hot no matter how much of it we use.Be is gas or electric both types have their drawbacks and to get ahead of the corrosion that always kills them we now opt for expensive stainless steel tanks...Using induction it would be very easy to have a fully sealed tank and to actually only heat what needs to be heated without wasting too much energy.The "heating" element could be just a steel plate inside the tank with no connections to the outside.The gap between wall and element doubles to make the water circulate.And changing from a fixed timer to a temperatur control system to turn the induction element on and off is not hard either.Do you have an induction based hot water system, heater or maybe kettle already?Would love to see it...

Using LiPo batteries in coil guns

Hello all, this is my first post! I have been theorizing for a while about coilguns, and have been doing calculations. here is how it goes: A single Lithium polymer battery can hold up to 3.3 Ah and discharge at about 30c (safely). We multiply 3.3Ah by 30c and get 99 A of continuous discharge. That’s a LOT of current, but, it is still not enough to fire a good projectile. So, I’m planning on having four of these hooked up in parallel to give out 396A. This is quite a bit of dangerous current, so my wiring will have to be gauge-perfect. The magnetic field that this produces is about 9.9 teslas, as  twice much as your average MRI machine. Yes, I’m utilizing a miniature MRI to shoot stuff. If you want to know how much force an MRI puts out, here is a great video to show you https://www.youtube.com/watch?v=6BBx8BwLhqg. I am planning on having a 2,000 turn coil, with the average distance from the projectile being 1cm. The ammunition is going to be BB bullets, which means our cross-sectional area is at least 7.65*10-4m2. Using those numbers, the initial force on the BB is 3,015,030N. This is enough to lift up 25 semi-trucks. On paper, this seems magnificent. However, I’m accounting for about 2% efficiency, taken into account at this step, giving us 60,300N. This is still an enormous force to take to a .5g BB I’m implementing the Impulse to be .05s using standardized E = F * t,  this gives us 3,015 joules of energy. Huh. that’s way more than we should expect. Let’s take into account the 2% efficiency rating again, and we get a more realistic number: 60 joules. 60 joules is ridiculous for a BB pellet. We’ll use Ek = 1/2*m*V2 to solve for V. I got about 1,553 m/s. This is faster than most guns shoot regular bullets. I will be using a 2-stage setup, and will make sure to  use proper electrical equipment. My question to you is; How accurate are these calculations? if I build this thing, what can I excpect?

The ultimate challenge?

There are always good contests available for those keen on competing, but what about a real challenge that might run for many months? I am talking about rediscovering ancient technologies and ways of creating things. We have a lot of evidence that is in massive contrast to what archeologists want to make us believe. Be it the way the pyramids were build or just in what timeframe, the use of technologies thought to be impossible at that time or just the knowledge of things like star constellations that are not not visisble to the naked eye. In a lot of areas it seems not only archeologists but also some "secret powers" try to put a hold on discovering what was really possible thausands or maybe even millions of years ago. Things like the knowledge of distand star systems that are invisible to the naked eye might never find a suitable explanation. But what about tools and technologies used to create stonework that is hard if not impossible to create with our modern tools and technologies? I dare everyone to participate in the impossible! We know thausands of years ago milling, drilling, machining and lathe work was done but we have no real clue how it was done. At times when the rest of human kind was happy using stone tools and otherwise just hunt and gather for food some areas saw an explosion in technology. Within less than a few hundert years some builders in Egypt went from simple and explainable works to stuff impossible to do in today times. Same for India, the UK and the american continent. No hardend steel tools were ever found, no machines, no evidence on the how to, just the perfect work. Here is the challenge I propose: Come up with: 1. A way to cut or drill granite and harder rocks without modern tools or tech and still do it faster and more accurate. 2. A way to match hard rocks to each other with a precision down to less than a mm - as shown in many ancient buildings preferably on a big scale. 3. A way to create delicate carvings in hard rocks, things like hollow heads less than 5cm in size or cravings with spaces of less than 3mm wide and several cm deep - as shown in many India sculptures. 4. A way to build a lathe capable or turning several tons of steel with an accuracy better than half a mm and without electrical or combustion engines. 5. A feasable way to transport and accurately position several tons of stone - again without electricity or combustion engines. 6. A way to create sculptures with an accuracy shown by the ancient Egyptian ones, meaning perfection... 7. .... I could go on but I guess you get the picture ;) The solutions could be as simple as using sound and vibration or as complicated as finding a way to create tools hard and durable enough to proove the archeologists are right after all. And before you cry out that it is impossible: Consider the evidence! We know it was done but we don't know how, so let's show the world how we at Instructables solve the problems noone can explain ;) I can't offer any real contest, prices or such but maybe someone is reading this and willing to provide the base and soem prices?

The Newman Motor Challenge !

I was recently approached by someone claiming the old Newman Motor wouldn't be good for anything.Well, I was a little bit offended by this as I already had my little toy version of it as kid.At that time though it really was just a toy for me.Critics still say the Newman Motor is nothing more than some interesting machine.And even the biggest followers will admit it is not a free energy machine, just a very efficient one.I experimented with, what some call fringe science, now for about 30 years.And it all started with math and my interest in unusual ways of dealing with problems.So what's behind the challenge?The original design was suprisingly simple as you can see in the above Wiki link.Just a spinning magnet in a (split) coil.What you don't find anywhere though is real details on the how to.Sure, you need to have some sort of contact linked to the rotation and timing is critical but what does it all do?You can build a drt simple model in a few hours with stuff you might have around already.Quite a few Youtubers are happy to share their creations.The actual challenge is to come up with what Newman really did inside his drum.And also why I think it is not the full potential his machine had.Build a simple Newman motor and check for how long you can let it run on a charge super capacitor.Then sit back and read some of the other magnet stuff I wrote.After that come up with a better design ;)I started to create some 3D models that need testing once I find more free time - should take some leave one day..But for those with little patience and an interest in the Newman Motor I decided to share my current idea:For some it might be really confusing although they know motors and magnetic fields.Those just playing with magnets might have it easier for once as they can pretend they followed my thoughts ;)The original design used two coils and a rotating magnet.If you consider how the magnet creates an electromagntic field in the coils then you have to wonder right away how it can spin.And most designs will indeed need a push start to get going!You can't have electricity produced without the magnet spinning and you can't make it spin without electricity!The current from the battery or capacitor can only flow at the short moment of contact on the axle.This moment needs to be timed "mechanical" as we don't want to waste any power on not required electronics.If you ever bothered to check the timing of a Newman Motor then you realised the collapsing electromagnetic field at the moment of contact actually is in reverse to what the manget has in that position.Unlike any normal motor it means the magnet produces most of the power the coil needs to make the rotor spin!So far for the well known facts, now for my fiction:I would like to call my version the Aussie Newman Motor as all things downunder are just different ;)Here are my current desing mods, that I freely share so everyone can benefit form many years of experimenting to save a lot of time.1. Instead of two coils a not-really-bifilar coil is centered on the axle.The coil is created like two stacked relay coild that have no bobbin and a "dint" to allow the axle to pass through.Without the big gap of the original less of the magnetic field strenght is lost and the coil is far closer to a homogenous magnet.2. The timing done by salvaging a simple DC motor's contacts and brushes.This allows for far higher currents and if the salvaged motor had enough poles also for a very short "burst".3. The axle contact is made with a cleaned steel bearing.After cleaning very conductive copper based lubricant is used in tiny amounts to prevent corrosion and provide a lower resistance.The clear benefit is that with the new timing system a lot more current can flow.Initial tests with a mock up model showed an increase in run time from the capacitor of about 15% already.With proper bearings and a salvaged DC motor I hope to reach 18 to 20% more than the original design.Now why the DC motor if a reed contact or hall effect sensor would be even faster and with less resistence?Neither can handle really high currents without additional electronics ;)Plus of course I wanted to leave the door open for the Aussie Newman Motor 2020.You might now say "Why bother if the above improvements are already so great?".If you followed my elsewhere for a while then you know the Newman Motor is only 2D but I prefer 3D or more harmony if you like.Right now the imagination of people re-inventing Newman's machine is limited.They try to get on the horse from behind - literally.Fancy electronics, machined parts and so on.But they never go 3D ;)You got it? :)There is only two coils!!The magnet rotates, same as the contact on the axle.One set of coils for each contact the salvaged DC motor has.Each set aligend to the corresponding contact.And now you will ask "How do you plan to connect that to a single DC power source?Well, that is why it will be the 2020 model - my time for tinkering is sadly limited because I still need to work to support myself.But if you consider that the original as a good model can run for over 10 minutes on a supercapcitor then ask yourself how long it could run on 4 or even 8 coil sets.And although there is no such thing as "free energy": There will be still space for more coils.Or other coils to just provide electricity that does not power the motor.Critics will now see their chance and state that if we add a load to these additional coils then this will cause a strain on the system.Of course they are correct here.If, however, the load is mechanical then the motor needs to supply basically the same additional energy.Plus all mechanical losses.The question is: How much mechanical load can we add before the motor is down to the same efficiency of a very efficient DC motor? ;)And what if our Aussie Newman 2020 would actually violate the laws of physics?We can calculate how much electrical energy would be required so a given motor produces a fixed amount of torque.Or we can just measure it, the beauty of science...We can do the same in reverse of course.Let's say a mechanical pump would require 500RPM and 100Nm of torque to pump 100 liters per minute.Then we could calculate what sized motor we need to drive the thing and how much power the motor would need.So again: What if the Aussie Newman 2020 would require far less than what science makes us think and still does this job on a simple 12V lead acid batty of 4Ah?Just saying... ;)I hope to have a presentable and working 2 coil system by May, so stay tuned!In case you are faster or even beter then of course feel free to show off your results or to post a link to your Instructable so everyone can verify it.

3D Printer Enters A New Stage Of Development

  As a new type of manufacturing process that using rapid prototyping technology,3D printers aroused widespread concern when it was published. A new product was initial pushed into the market, people concerns its functionality and price more than its shape and so on. 3D printer is no exception. Initially, people's attention focused on its cost and performance.   What way reflected cost and performance for 3D printers? I believe that there are three main areas, including printing speed, printing volume and resolution. For consumers, what level achieve these three areas and which brand is more competitive? Next, I will be based on my own experience for everyone to make a resolution.   As a Chinese brand that created independently, LXMaker won the favor of consumers from different countries by its excellent performance when it was pushed into market and sales was rising gradually. Recently, LXMaker launched a new all-metal 3D printer that was named Iron Man series.Three aspects of the machine has been greatly improved.   First is the super high printing speed:Take advantages of the cross shaft structure innovation and the unique design to separate feeding device  with extruder at both sides, instead of Makerbot's heavy printing head (loaded with 3 electric motors, illustrated as below). LXMaker's light & handy extruder guarantees high speed printing. Imagine, if you are running, unloaded or  carrying bags, which is faster? The maximum nozzle moving speed of LXMaker can reach 500 mm / sec .     The novel cross shaft structure introduced above has win the big prize of "The Best Open Source Hardware"and"The Most Precised and Fastest 3D Printer",nominated by the world-wide well-known Make Magzine.   Second is the super large printing volume:The maximum printing volume is up to 260x260x400mm, outstanding of 3D printers at the same price.    Finally is the super high resolution:LXMaker has a very precise Z axis movement, which ensures the precision in practical. The theoratical precison of Z axis is 0.01mm, while the actual test precision is only 0.02 mm, which guarantees the super high quality of the workpiece, and can effectively prevent deformation in the printing process. Ths precision of X & Y axis can also be as high as 0.125mm.   In addition to excellent performance,the price of the Iron Man is very close to the people.The machine of maximum print size that need 2199 dollars was located in moderate level in similar products, so that consumers that come from all countries were able to withstand it. Because of this,LXMaker owned today's sales.   As time goes by, the point that people focus on the 3D printer was also not limited to the cost and performance, but rather more attention appearance and stability of the machine. Because considering this change,LXMaker introduced Iron Man series.   Iron Man series used all-metal structure and the whole machine has a very high stability.In addition,it was very strong.And it didn’t produce crack or fracture because of a slight collision. So it has better adaptability for long-distance transport, consumers do not have to worry about damage of product because of long bumpy.   At appearance of the machine, Iron Man series launched black red and blue creatively.According to their preferences,consumers can customize the 3d printer that belong to themselves.And three colors of the machine is filled with the fashion sense and the modern sense.This feature meet the requirements of the product appearance that digital technology enthusiasts. The method of LXMaker is designed to meet the trend of customization.   New products always went through a process that from performance to shape after published. Eventually,the overall level of products will be improved by leaps and bounds. 3D printer reflects the development process of this law fully. Therefore, the most critical for the business is to discover consumer’s mindset changes and adjustments based on the changes in a time.It is the only way that owned good yields and returns. The only constant is change.

Why is almost every free energy video you find a hoax or fake?

The term "free energy" is used both ways by us.What comes from wind, solar or water power is considered free energy.Also everything claiming to produce energy from nothing is considered free energy.Speaking of hoaxes and fakes now is a bit like comparing appels to tomatoes.For me it more like those stage magicians: It all looks real and impossible but they do it, so it must be real.If you really need to brag about your free energy device but are unable to sell a working model to interested people it at least means you are not a scammer.Several people play the game of exposing fakes.And if include this in your search then you get an idea about the amount of fakes or magically illusions out there.The internet is often abused to change opinions or make people do things they usually wouldn't do.Even if it is as simple as clicking on a suggested link for the next video.Patents can disappear or with enough money you can buy them off the inventor.One reason why more and more companies develop in secrecy and without ever applying for any patents - check the swiss army knife ;)There are no conspiracies involving "free energy" but imagine it would be the case...There currently is nothing that would actually allow you to produce enough electricity for your family all year round.At least not if you want to avoid several wind and water turbines and all possible areas covered with solar cells.If you would somehow make a device that produces more output than input (even if it uses up some form of stored energy like magnets) then how would you present it to the world??Could you take the abuse of literally everyone around you calling you a scammer?You know better, so you allow it to be tested - really??Unless you provide all details and open all up you would still be called a scammer.Someone offers you a lot of money to take the thing and have your assurance to never talk about it or invent something similar - suddenly not that impossible to think of...But what if there is no offer but threats instead?A nice show on the internet keeps you safe and allows the sceptics to brag how it is faked.What better way then to make sure there are tons of videos that show similar constructions that clearly can't work? ;)As with every good story there is always a bit of truth somewhere.Over 80 years ago people made magnetmotors that worked.Look it up and check their patents.Most of the fakes we see today are based on the same 4 or 5 machines from back then ;)Our modern life would not be possible without the inventions Tesla made.Still, basically all of his inventions that did not find public use are still considered bogus.How can one of the smartest man of that time have hundrets of used and recognised patents while those using them claim all the rest is useless and fake?Getting energy they can sell was fine.Allowing that everyone can generate all the electricity needed themself not so much.A free generator that everyone can build would never see a meter and you could not force people to put one on either.With unlimited money available those behind electricity, oil, gas and coal will always make sure that anything even just getting close to it will disappear.The internet changed this as now everyone can provide plans, videos and even all required parts if needed.Making someone or something disappear in Africa or Indonesia is easy, doing so with someone who has actual family, a job and lots of friends not so much.Money and contracts are the next best thing then...Remember the hype about Vortex energy a few years back?Videos claiming to have a vortex thingy producing more energy than what is used everywhere.Now in some regions vortex math is actually something people study.And with this the new videos about vortex based free energy devices went down to almost zero.Nothing new anymore that was not shown already.If you study a bit what Tesla did for students and teachers you will find a lot of similarities between his math and the new area of vortex math.But where those vortex guys use our modern math, limited constants and sequences, Tesla actually include all that was known at the time in his math.Like with scientology you have to work your way up the ranks in the vortex world.A lot of things you can only understand by confirming it in experiments, other stuff you will only get know when attending seminars.If you just get together what you find online and try to understand it then try again with a printout of Tesla's circle of math next to it.Knowledge is out there that we just fail to acknowledge or even try to explain if we see it.Just take ancient building skills.We know they did it because their monuments still exist today.But we would utterly fail to replicate this with our modern technology.Let alone with the tools claimed to be available at the time.....Levitation through sound was deemed to be impossible.Then one day we invented powerful ultrasonic speakers and it worked anyway.So how many real "free energy devices" are out there?How knows if it is one, a few or thausands.Same for all the websites and videos out there.After a while you learn how to spot the fakes quickly.Then you still find some videos where you fail to find the hidden battery or motor or power connection.In the end you are left with the same 4 or 5 possible types claimed to have worked almost hundred years ago.Eliminate the bogus and incomplete then there is still some left....It does not mean any of it actually works...That is if you exclude those few companies selling things like magnetmotor generators for a few years now.Going faster than a certain speed would kill you - then we moved on from steam engines.It will never be possible to use the power of the atom to produce electricity - we got nuclear reactors anyway.Now we even try to make fusion generators feasable...So ask yourself if all "free energy" bogus really is just bogus...We know life must exist on other planets outside out solar system but we still could not accept if this life would be more advanced or civilised than we are...Yet we feel the need "to go out there"...Where does Instructables come into play?Take the dare and provide a well documented Instructable that allows anyone to replicate your "free energy device".No solar cells or electric generators please, only stuff that should exist or work.If you don't speak or write english then use some translator and people here will help to properly translate it.The big community here will jump on it, find the hoax behind it and tear it apart.However if they can't then someone will build it to show that it can't actually work.Then imagine the surprise if "I made it!" starts to be clicked more and more...No one could stop the progess or hide it then ;)Of course we all know that nobody will ever post such an Instructable, don't we?Keep in mind that the scam behind "free energy" might just be result of too many scammers...

"Sonic" drilling or cutting

If we look up sonic drills today we usually get some fancy machines driving pipes in the ground, preferably softer ground.But the term includes all types of machines that use sonic vibrations to advance through a media.With the ancient and claimed to have never existed technologies in mind I did some digging...In the food industry vibrating knifes are quite common, same for "air knifes" on softer food.Even in the meat industry they find more and more uses now.Ultrasonic cutting or welding is the same thing and included in "sonic".Same for some experimental sub sonic drilling methods currently being tested.The general idea might be as old as using vibrating equippment to compact stuff, like concrete, bricks and so on.What you can compact by vibration you can also make "fluid" by vibration.Industrial feeder systems utilise this to the extreme by even making light and fine particles like flour move like water without causing any dusting.What all the techniques have in common that a suitable tool or tool head is used and that it is attempted to use the most suitable vibration frequency for the job.Anyone operating an ultrasonic welder knows the pain of finetuning for a new electrode or just new part to be welded.What does that tell us now that makes the understanding easier?Take a bottle of ketchup, preferably one that is still quite full.Turn it upside down and noothing comes out.Shake it a bit and you are either lucky or drowned in red.But hold it at an angle and start tapping it and the red sauce flows out easily.What it true for most newtonian fluids is in some way also true for non-newtonian fluids.Ever mixed corn starch and water to make these funny experiments with it?Hit it hard and it reacts really hard and is not sticky at all.Leave your hand resting on it and in sinks in and sticks to it.Stirring it very slowly is easy, go faster and you get stuck.You can do similar things with by using an external source for vibrations.For example a vibration speaker mounted to a smal cup of the goo.If you place sand on a sloped piece of plastic or sheet metal then at a low angle it will pile up easy and stay.Start vibrating the plate and the sand will start to flow off.Works fine with a vibration source mounted to a piece of steel bar or rod and a bucket of sand too.Trying to press it into the sand requires a lot of force, especially once you are a bit deeper.Let it vibrate properly and it slides rights down.If we can do the simple stuff as well as really complicated stuff in the industry then what about other materials?So far we use vibrations to make things move out of the way, compact things, transport them or to heat them up for welding plus some cutting applications.Considering the variety one might wonder why no one tries it for "difficult" materials.Machined surface can be found throughout ancient history.Finding "machined things" were vibrations was clearly used is a bit harder.The great walls are not a perfect example here as the views differ quite a bit on how they could have been created.But if we leave things melting them or a secret concret like recipe for creating for example granite then vibrations start to make some sense.You find some interesting videos on youtube where people use speakers, wires and rocks to confirm you can actually "machine" them by vibrations.Especially granite has some quite musical properties, big boulders as well as smaller ones produce destinct sounds when you hit them hard.Tests and measurements were made on granite and other hard rocks to check how fast sound travels in them , how it is refeclted and where the sound comes out or affects the surface the most.Lets just say every sample gave different results.Shape, density and dimensions affect not just the resonant frequency but also where and how the sound travels in the rock.What if??We can use a simple speaker, a plate and some rice to see how patterns form under various frequencies.Works with sand or other granules as well.The interesting patterns are the so called harmoncis.Here we see clear and destinct patters, sometimes with extremely fine lines and areas of softly vibrating granules.Some people say these harmonic frequencies have all special meanings and uses.We mainly used them to avoid problems.Imagine your new TV would not have a housing tested to be stable with all frequencies the speakers can produce.All of a sudden your back of the TV might start to rattle ;)Same for car engines.Harmonic vibrations are eliminated wherever possible.Otherwise they could multiply and affect other things in the engine or around it.Simply put it means we have various options to detect and measure vibrations on a surface or in a system.Back in the day every half decent backup generator had a mechanical indicator for the frequency of the supplied electricity.A set of tiny forks with the desired on painted red and several on either side of it.These forks were designed to get into harmonic and therfor quite intense vibrations at their set frequency.If the one for 50Hz looked blurry then all was good ;)The same principle god be applied on a big boulder of granite.Place the "vibration meter" at the desired spot and start moving around the vibration source on the surface until you find a spot that causes maximum response on the meter.Best thing here is that if you then place that surface area onto another peice of fixed in place granite both pieces will start to loose substance if vibrations are applied.The fine sediment forming is then usable as an indicator where to move the vibration source to continue once the effect literally wears off.Is it feasable?Well, if we trust mainstream science then the answer is no.A huge amount of vibration energy would be required for such a hard material, despite ancient proof that says otherwise.Semi industrial test also seemed to confirm the theory as only with very high amplitudes (loudness) and while automatically adjusting for the resonant frequency changes a measurable amount of material was removed.I struggle a bit with that as for the testing tool heads made from hardened steel or carbide were used.And that with little or no regards on how the head and tool itself affects the output.I mean in terms of having the max possible movement happening right t the tool contact surface!There is a huge difference between applying a vibration to a tool and using a system, tool and tool head DESIGNED to work at the desired frequency!Otherwise we wouldn't need a computer to design and test a horn for welding purposes or shade a knife spefically so that the vibration go along the right axis and in the right direction.You not break a hard thing with a very soft thing unless it travels fast enough to become harder as the target!This complicated explanation basically just confirms that if you hit water at a too high speed then it will just break you into pieces instead of offering a soft splashPlease do not jump of bridges or such to confirm this yourself!!If that is really true and science says it is, then how about the other way around?Works fine too, or we wouldn't have pressure washers or water cutters.Now for the part where I hope some really smart people leave helpful comments:If we can cut steel with just a stream of water, then I ask:Isn't for example copper much harder than water?Steel is much harder than copper but water cuts through it.The answer here it simple or complicated, depending on how you want to expain how it works.Comes down to speed and pressure plus the right nozzle shape to prevent a beam expansion.But then water is indeed "harder than steel".Questions:Lets say we would use a copper pipe that in lenght, thickness, hardness and diameter is optimised to transmit a frequency so the pipe end sees the max vibration like a feed horn for ultrasonic welding.Not to hard to calculate these days :)Now imagine said "main frequency" would be optimised for the pipe but also be a harmonic frequency of the rock to be worked on.The pipe end would deform quickly, abrasion does the rest and it fails before even making a decent sratch that is not copper metal on granite.No matter how hard we press nothing good enough will ever happen.BUT: If we would add more hormainc frequencies to feed our pipe we can multiply the amplitude quite easy!Just try with a sound generator from your app store, needs 2 or more channels to be usable.Pick for example 400hZ on one and 800Hz on another, then finetune around these number to hear how the tone changes ;)My theory goes like this:If all "working frequencies" would just harmonics of the resonant frequency of the granite, then they can be tuned so the effect on the pipe end is minimised.The overlaying frequencies however should result in the same effect a water cutter has: The pipe becomes ultra hard.The better the match and the more you have to get it right the harder the pipe will be.Adding now a "drilling frequency" or multiple could be used to drive these harmonics slightly out of phase.Like with the sound generator on your phone we end up with a pulsating sound, or vibration.While the pipe still vibrates at the same "hardening" mix the drilling frequency creates a peak like a jackhammer.Try it by using the heaphone output on a small speaker and placing some light and tiny things into the cone.The will violently jump around during these pulsing tones.For a drilling system the output can be mechanically maximised by utilising a pitchfork design.A head holds the vibration speakers and the tynes are tuned good enough to the frequency of the speakers.Always two would have to operate in sync though as otherwise the pitchfork movement that transfers the sound down the center bar won't work.This head could then be desgined to act as a holder for a quick change of work out pipes that are no longer long enough for tuning.I guesstimate that a well tuned design would result in a copper pipe being able to drill at least 10 to 15cm into solid granite before it wears off too much.And we are talking here about just a few mm to get the thing out of tune!But would dare to desing such a thing just to confirm a theory that no one ever really dared to test? ;)And if friction welding works as good as ultrasonic welding, then what would happen if we try this with the right frequencies and vibrations instead of wasting tons of energy?

Magnetmotor - really impossible or just supressed?

When someone starts talking about a so called magnetmotor than most people judge right away.Laws of physics, perpetuum mobile is impossible, magnets are static....We all know the limitations nature puts on us... That however did not stop quite a few people since the 1950's to build working magnet motors. Or, to be precise: To make the claim, show them and then somehow disappear. A few though seem to have survived and even claim to make good business. Securely closed machine, stellite tracking and 24/7 online monitoring. Either just a bad and long running hoax or a real attempt to keep a secret secret. Even the somewhat famous Yildiz motor showed off around the world only to disappear.Some like them, some don't. Either way all this sounds like the perfect conspirary theory LOL So lets take a look on what is fake and what might be real but missing some vital clues. You can find several good Youtube channels created by people trying to build a working magnet motor. Some of them have no problems to admit failure and still keep trying and updating their projects. Did long enough and you see two outcomes. The first is giving up or "realising" that it will never work. The second often seems like a user is getting some relly good results and is really close to keep the magnetmotor running. Both disappear without and updates or traces. Now of course this is just confirmation that it will never work, but then again: What if it did already quite a few times? Even Tesla had patents for a magnetmotor and so far none of his patents were a hoax. Although none of his patents allow to actually build a working devices without some additional info and knowledge. And that is the key that I am trying to get: The lost knowledge.How can a magnetmotor never work? That one is quite simple from the start. If a linear model won't work no matter where you start then a rotary version will fail as well. And if a linear version works, it has to do so far at least 5 segments and with preferably increasing or at least constant speed. Having said that and assuming you know a little bit about magnetism: Ever wondered about shapes of magnets?? The common types are block, round like a bar and those disk like ones, some even with holes. A less well known version is the ring magnet. You can look them up as well as their corresponding magnetic field geometry - or what is assumed to be the right geometry. To give you a clue: All those floating spinning toys use a ring magnet in the base and onother one in the spinner. In the center is a dead zone for the magnetic field that is far lower than further out on the ring. And the strnger outer fields also reach further - giving the entire spinner a bowl like area to float on, the spinning just stabilises it like a gyroscope. A similar flat disk magnet wouldn't have this indentation in the field but rather a dome like sphere. The ring just kicks a dint into this sphere if you don't mind the simpification. Similar changes in the field structure happen when you combine two or more magnets. One example we all know is stacking identical smaller magnets. And often we are suprised how much stronger two thin disk magnets are compared to a single. Distance however sets a certain limit. And take those hook magnets... Just a small ring magnet in a metal pot with core. Remove the magnet and just by itself it is far weaker. Why? Quite simple.... The same way a transformer core directs the magnetic flow, the metal part of the hook magnet provides a shortcut for the magnetic field - and in return all is much stronger ;) Now you have some more clues, but still there are tons of options for failure... The most common is the sticking effect. No matter how well you planned and designed in most cases you linear or rotary prototype will stall sooner or later. Even if started manually at high speeds some seem to run very long but once they slow down and stop it is obvious they always stop where the magnetic field won't allow the binding effect to be overcome.Wouldn't dare to say that I have a working magnetmotor, but I might have some clues you want to try if you decide to give it a try yourself. So how COULD a magnetmotor actually work? Like in the Perendiv examples all over the web, you could aloow a moving responder to the rotor. Like a piston the responder will be lifted in areas it would otherwise limit or reduce the speed of the system. Well designed only a few mm would b required but it also means wasted energy to move the responder. Then there is the nice way of modifying fields by adding magnets in different angles and polarities. Lets say towards the end of your stages on the linear model it is hard to overcome the binding effect from the end of the previous stage. The perendiv model would now somehow change the distances. But you can also add magnets to lower the binding effect ;) Like a ring or hook magnet you can shape the field and offer a stronger repulsin field or a lower binding force. Last but certainly not least is the option of adding magnetic metals like iron or somehow weirder ones like bismuth. So, do we have any examples of something very common utilising any of this? We sure do :) Take a speaker apart and you end with the cage, the membrane, the actual work coil and the magnet. We don't need anything but the magnet so take a good and very close look. What in the audio world is called a shield to prevent the magnet from messing with things close by is exactly the same as on a hook magnet ;) Only difference is the tiny gap for the coil. The magnetic field is directed into two paths, one by the metal core, the other by the inner enclosure of the magnet or the magnet itself. The coil operates in the area of maximum flux.Last hints... If you take two identical and strong magnets with north or south facing up then it is quite hard to push them very close together. But check what happens if you try the same wen both soth poles (or both north poles) are placed on a magnetic surface - if in doubt your standard fridge door. Suddenly you can move much closer together with the same amout of force (not considering the added friction!). And similar story for opposing configurations. Where in free air or on a table the magnets would just jump together, on a metal plated you can move them much, much closer before this happens. Copper pipe and magnet fun :) Ideally you would have a straight copper pipe and a cylindrical magnet that has a loose fit in the pipe. Aluminium pipe work too or even a roll of aluminium foil if you have nothing else. A magnet in the pipe will travel very slow down the pipe, friction is not an issue here. So what is slowing it down? The magnet creates a field in the pipe and through that the pipe generates electicity. And funny enough this electricity creates an opposing magnetic field in the pipe - the magnet slows down. Even if you glue it onto a wooden stick it won't rush through it. Trying to push it by hand and you feel the created resistance. The faster you push, the harder it is to push! If you made it all the way down here with the reading then I have to assume you fit into one of three of my categories. a) You are a total sceptic and just read it for your amusement. If so, then please don't post a reply with usual negative feedback, instead see it as the same fun you had reading it ;) b) You are at least curious and like to play with magnets. In this case take the above as inspiration to explore more ways to have fun with your magnets! c) You are more or less frustated because you wasted a lot of time and some money to build a magnet motor that just won't work. A and B might go on and enjoy the fun, C however might want to read very attentive now ;) If you take some indicator sheet for magnetic fields, like these funny green ones, and play with moving magnets then you see a very interesting effect on the "screen". The otherwise static field lines change chape and sometimes even seem to disappear or shrink. With a small rotor assembly it almost looks like flashes when the magnets move past each other. This effect is often totally neglected and to be honest I overlooked it for a long time as well. Being able to see how the magnetic field changes gives the thing an whole new dimension so to speak. Creating a magnet with a complex shape is difficult to say the least. Only ferrite or ceramic ones can be used and you would cut of machine them according to your desired shape and with regards to the orginal center of the magnetic field. So most people revert to the classic way of shaping by adding magnets of various types, sizes and amounts. Modern neodymium magnets make this trial and error process easier as there are many sizes and strengths available. Add a detector shield of suitable size and you have hours of fun time ahead of you. But doing so in any rotary assembly is next to impossible. So what did Yildiz differently and what was missed so many times? Yildiz took it a step further and not only provided "shunts" to create very strong magnetic field from the generated electricity but also a second rotor. Since we all start small lets focus on the basics first. Remember the hook magnet and speaker or the copper pipe? Some examples for shape shifting your otherwise static magnetic fields: 1. A magnetic metal "connection" from one (low in the armature) pole to an opposing (high in the amature) pole with cause the field from the "high" pole to "bend" towards the connected magnet. 2. A magnet with an orientation of 90° to the last magnet is the sequence will severely influence the field of this last magnet! This goes for either orientations! 3. Adding a non-magnetic "shield" around a magnet, like a piece of copper pipe, will not affect the static field of the magnet. However it will severely alter the field of the enclosed magnet when another magnet passes it! It will also affect the overal field during the passing as the moving magnet will also induce a field in the copper by affecting the field of the enclosed magnet! Thickness and lenght of the shield influence the strength of these effects. 4. In a simple perendiv motor design the bar that creates the attraction for the spinning part is a magnet too. Either a long bar type or two small ones with an iron or nickel rod between them. There is no need for a piston or something that drives the bar up or out of the way ;) Just use the right magnet at the right spot on your rotor to repell the bar ;) Mount the ar with suitable springs and you suddenly can have multiple stages on your rotor instead of just the usual one! Don't forget the moving magnet on the opposing side of the segment in question though as otherwise you still will get stuck. (Hint: You can place a small but powerful magnet in the center of the opposing bar ;) Just make sure you limit the springs movement so the bar won't be pulled closer)Ok, hold on now! Does a magnet motor actually work or not? I can only give hints and say the laws of physics as we know them apply to magnetmotors the same way as everything else. Unlimeted motion without supplying energy is not possible. Limited motion with adding or using energy however is still possible and real. The same is true for being able to machine, 3D print or otherwise manufacture at very tight tolerence and accuracy levels. This includes bearings or bearing systems with very little friction losses. Just check these floting and rotating magnet toys that look like a spindle. Only a tiny needle like pin makes contact with a glass surface - next to no friction loss. A proper and supposedly working magnet motor should provide more energy than what it uses - one way or the other. No law of physics lets us get around the fact that such a motor could only keep spinning if the produced power or motion energy is at least the same as what is required to make it move. Magnets lose their strenght over time, they are like a very slowly depleting battery. So, isn't it funny that all magnet motors so far that claimed to work also had the requirement to replace the magnets once the things fails to work or start? And if you leave a very strong neodymium magnet shielded from outside fields or magnetic stuff than your grandkids will still find a quite strong magnet. Do a little performance test with your new magnets, like how much force is required is required to lift them off a steel plate. Make the same test with the magnets once you played around extensively with them in your motor. Now take a spare magnet that was never used from the orginal batch and compare both against each other ;) If the motor would not use energy then why are the magnets depleted to a certain degree, realted to runtime and usage time? Wait a minute! Does that now mean it actually works? Lets just say energy is certainly used. We only know similar effects from electromagnetic systems. But did anyone ever really check how much actual energy is in magnetic field generated by a non electric magnet? Get a good sized N52 neodymium magnet and check how much force is required to pull it off a steel surface. Now try to get the smallest sized electromagnet capable of that force and check how much energy it consumes at the level that equals the pulling force of the N52 magnet ;) Makes no sense to even try to compare these you will say now. I just say energy is energy and we were formed to only think in certain ways and don't even try silly things like this ;) To keep the fun up let us imagine we would actually have a similar energy available than what our electro magnet would require. In reality more because we wouldn't have electrical or flux related losses in the metal around the coil. Or is the imagined reality, no clue ;) If true it would mean even a motor with very bad efficiency would be able to create huge amounts of torque. Well, torque is basically acceleration. Which would mean our motor would not just be happy to spin, it would speed up until the bearing fail or the thing is ripped apart. Imagine a dental drill of that size and weight suddenly falling apart at full speed... Every example of motors claimed to be working, that are not fakes, seem to be happy no matter what the load is. It the thing turns a generator than it would have to slow down a bit with the increased load but they don't. With no limited factors otherwise this makes them a fake. Even a perfect motor would have to react to load changes.... Don't we agree that the stronger the magnetic force or field in a conductor the stronger the resulting magnetic and opposing field of the conductor? We use the difference to either drive a motor or take out electricity... But if you take the "open" shielding of a magnet in a changing field than the influence of the shield on the overall field gets stronger with stronger field changes. And properly desinged and orientated they would actually double as a natural limiter for the rotation speed. Once the electrical energy in the shield becomes too strong it will be able to cancel out the field of the enclosed magnet...If we assume a magnet motor is really possible and works with the intended output to keep it spinning or even take energy out: Then what would be possible downfalls that stop this thing happening in everyones garage? We can explore the stars but so far no one bothered to invent anything to visualise magnetic field in a 3 dimensional way other than by simulation. No realtime and true observation like this. The few working technologies that exist rely on sensors, interpretaion and filling in gaps. But imagine something like a detector shield as cloud! And then even better with selctive spacing to get a realtime view of where exactly the field lines go. All we can do is forget our teaching and try it out anyway ;) If by some mistake a magnet motor would really work right away, then chances are high the inventor would wonder why that thing takes off like mad and how to stop it. Unless well prepared it would certainly end in the destrution of the motor. But the inventor would know what to look for in the next prototype. The logical conclusion would be to the couple the energy taken to the speed while physically limittin the free load speed. The other one would be the design the electrical generator around the and within the motor. To even get close to this point you would have to spend endless days and nights working on finding a solution. The closer you get the more disappointment when the final model still fails to keep spinning for more than a few hours. Most people will then accept defeat and move on... Still not saying it actually works but if you made it to this point in time where it could be easier to move on and do other things:Ever wondered what would happen if you "shield" a magnet with a coil? Of course nothing would happen as we know. But try this in some fixed assembly that allows you move another magnet through the field of the shielded one. Perferably witha force gauge or some option to read out the energy required to move it through the various stages of the field. See what happens if you short the coil or add a resistor to it ;) Now if this coild is able to produce electricity then the more we use the more the effects on the required force would change. What do you think would happen if you combine common coil relations of electric motors to a "coil shielded" magnet motor? Right, all these coils would interact with the magnetic fields of the coils they are connected to... And through that with the overall field surrounding the enclosed magnet..... I leave up to you to imagine how these interacting coils could provide "resistance" or "acceleration"/"surplus electricity"...Like they say: You can only find out if you try ;) To keep up the positive thinking: A permanent magnet just sticks to any magnetic surface and does so with the same force. But the real energy loss in terms of getting weaker can almost be neglected. Any electromagnet capable of the same holding force woul require ongoing energy supplies to keep it up. It is using energy the same way the permanent magnet does! The difference is the permanent magnet is not seen as anything that would provide us with energy.... And if it can't provide energy other than passing through coils then why the heck does it keep sticking to the fridge year after year? It does require energy to keep this weight up doesn't it, even if you add a thin teflon disk and oil to reduce friction? ;) No magic, no "free energy" bogus, just plain physics viewed from a slightly different angle than what we learn in school ;) Have a good laugh and a good beer, then read it again and just consider some of the things here that are not mentioned in any literature about magnetism that we commonly use. Now I got you thinking, didn't I ? ;)
