Need a Gas Tank

Hey guys, this is my first time on the forum section of the instructables! Not a bad place to be, really. So here's the thing. I have this old scooter that I've had for as long as I can remember. It was the very first thing I rode that was powered by a motor and my father bought it for me so I could get ready for my first motorcycle (Which was sadly stolen about a year ago :/). Last year, my dad went back to our hometown to visit family and he brought it back with him, but there was one problem. We have no gas tank for it. I have NO idea where it could have gone or why it wasn't brought back. Oh well though. I have this scooter, the same as Wesley666 does. I'm having trouble finding the gas tank on my own. Notice that there is a gas tank that I took from a weed eater just to try it out. But I'm not sure it would work out very well. I mean, look at the size comparison between the two? I also want to keep original parts on this nostalgic machine. Sorry if the pictures are oriented weird, but these are taken with my phone.You can see from the thread posted above there is a picture that shows a blurry close up to the gas tank and I can't really tell what it says. "Something EBR Motor". Long story short I need to get that gas tank, maybe even the gas line that comes with it, in order to get this thing working again. Does anyone know of the brand name of the scooter so I could get the original parts I need?

Should I bother with this lathe?

My father-in-law told me that he has an old lathe in the basement, it was his father-in-law's. I've been wanting to get a lathe, but not really being able to afford anything, but I'm not sure if this is any good or even worth trying to work with. I don't know what's missing (but I know things are missing). Missing parts may be in the basement, but I have no clue what I'm looking for. Edit: I got the picture of just the lathe to upload finally.

Coanda effect in conjuction with Venturi effect !?

I am still working on my project to create relatively accurate model of a Repulsine. No, I am not one of those free energy nut balls, just curious in old tech ;) As part of my research I came across some statements in regards to lost pieces of the Repulsine. The last remaining model still exists in Austria but noone seems to have to clue what the missing parts looked like. I think the missing parts are a system of nozzles, diverters and a secondary hull - forming a similar system like the Coanda plane engine. There are lots of people still out there tinkering with Coanda lifting devices and trying to get them working. Is there anyone here doing it ??? Would like to exchange some knowledge, tipps, designs and so on. Short term goal is to make working Coand engine with enough thrust / lift to be used at a later stage for a working Coanda plane model. Long term goal to modify it all to incorporate into the Repulsine.

Simple Zapper Idea

BUT... is it possible to do this same thing in my home on a smaller scale by wrapping wires around some of my powerful earth magnets? The reason for asking is that I want to increase the current flow so that it starts zapping when the wire ends come near, also I want to create a ground based bug zapper for fun that will allow the zap to travel through water (shallow puddles). Sorry if I'm missing some law of physics that renders this impossible for me but I'm not taking the advanced course for science and we only touched on  the topic electricity.

How to compress air into a hollow solid without a valve?

Hi  Really need some help with this one, have searched everywhere but cant seem to figure it out. I know there is probably a very easy solution i'm missing so please help. Basically I want to compress CO2 at around 80 psi into a hollow metal. I have drilled a micro hole and created an opening (about 2mm radius) into the metal. My problem is after I compress the CO2 in there how do I remove the compressor nozzle and seal the hole without the CO2 escaping.  The metal is small and there is no place for a valve. Is there such a thing as a self sealing removable valve? Or could I use a valve  with two openings and pump liquid metal (that would than solidify) and seal the hole so I can remove the compressor?

Adhering joints for intricate wire sculpture?

I would like to make a wire sculpture that is as intricate as I possibly can make it.  I want to use very small gauge wire (don't really care what material), cut small pieces and connect them together.  For a visual, I did a (sloppy) sketch of the idea and attached the photo, and it would continue to expand from there.  There will be multiple joints close to each other, done one at a time.  I want to create in on the fly, I will not have any pre-formed pattern.  I've been looking at soldering, brazing, welding and I don't see anything that would fit perfectly for what I want to do.  I believe the heat from the next joint would destroy any previous joints.  The idea of simply zapping a joint and quickly moving on appeals to me, but I don't mind being more patient in order to do it right.  Are there any techniques that I’m missing?  Anybody have any ideas?  Maybe I’ll just use superglue…

The wheel jig should be able to hold quite some weight because of my backpack and should be able to fit inside it for me to take it to school. I cant take a skateboard or scooter because I don't have any and it's not allowed to chain it to the bus stop and I don't even have a lock or a bike.

Short range radio pulse transmitter design?

I need something simple to transmit pulses 2-3 meters to a receiver The transmitter will output a pulse every few seconds, transmit a small burst at X frequency. The receiver then outputs a short high pulse/outputs high for the duration of the received pulse. I want this to be as simple as it can possibly be, cost being the primary restriction and power usage being also of fairly high importance, so please no suggestions of Bluetooth or xbee type systems. It does not have to be a radio based system, however it needs to work without line of sight and of course without connecting wires. If it helps the overall aim is a 'safety signal' that will set of an alarm at the receiving end if several pulses are missed Anyone? EDIT: To clarify I am looking for simple, like really simple. So the transmitter is just a resonator and antenna. What I need is a simple receiver that will respond to a specific frequency, on or off. Does such a thing exist?

Identifying plastic so I can weld a repair

I am repairing a broken wheel on a old lawnmower for which spares are not available. The hub (holding the roller bearing) has broken away from the rim and tyre. I've managed to weld the two parts back together using the hot air gun on my rework station but some small pieces are missing and I'd like to replace these and reinforce the welds by adding material.It is possible to buy rods of different plastics to carry out these repairs but I need a better understanding of the material I'm working with. It is an opaque white plastic with a greasy or soapy feel. It melts relatively easily (I used the heat gun at 180 degrees C) and bonds back to itself well. I suspect it is a polypropylene of some flavour - straight Polyprop, HDPE or LDPE.I don't have scrap material to test without removing some from the wheel. Any thoughts on what it is likely to be and do I have to know exactly which it is or will the different materials bond with each other?

If I remove the coil from the terminals I am able to get nice sparks. So, why this circuit won't work as expected? I miss something? However this is the circuit: http://s4.postimg.org/fgd78werx/ignitercircuit.jpg Please note that I'm aware of the fact that these kind of circuit could be dangerous; I'm taking all possible precautions (I'm using it far from any electrical device, I'm using isolated gloves, and so on). I just want to make this circuit for fun. Many thanks.

Building a convection model for plate tectonics and ocean currents

I'm building a model to show our museum visitors how convection works related to plate tectonics.  (It can also be used for ocean currents.)  I'm stuck on the heating source, though, because we cannot have open flames. The model is a cell of water, about 0.5" wide X 10" long X up to 8" high (depending on water depth). I would to implement some type of circuit with a resistor that produces heat at the bottom, and inside the cell, and battery powered.  At the top at either end would be ice cubes, to cool the water so it falls back down and recirculates.  To see the currents, the ice cubes have blue food coloring, and I use a long pipette to inject coloring at the bottom near our current heat source, and mug of hot water. I'm having trouble finding information on: - what type of resistor (how many ohms?, anything specialized for being submerged?) - how large a battery/ies for a 4-hour day on the floor (rechargeable, of course) - other steps to prevent corrosion It will need an on/off switch and a battery connector, too, of course... I'm sure I may be missing some other important things to consider, too. Any feedback would be great. Thanks~ -Adam-

Using a webcam to do digital video from a microscope.

I don't have windows set up for the net so it was nice to buy a cheap webcam that works right away in linux  and skype with my sister and brothers in different parts of the world.  It has a focus ring and I tried it with my microscope and prepared slide.  And then later with greeny water from plant pots in the back garden. It is actually pretty good.  I had to use 2 software programs. I used cheese to open the webcam but it misses frames when it records its own video!  I found that opening recordmydesktop and recording the cheese window or cheese area of the desktop solves the problem. I got the microscope second hand in a thrift store. Next step will be to find a pond and grab some really nice samples. I will grab pics of how I set it up in a while, but for now here is a video of a prepared slide, and focusing through it. <br> I did some other videos too with live specimens from the back garden but nothing really exciting.

Vandergraph generator

I am interested in building a small  vandergraph generator.  I am thinking this will certainly be no taller then 2ft and likely closer to 1ft.  I understand the general principal of how it works and this should be a good first voltage project that I should have everything I need for.  What has been holding me back for quite some time is that I could not come up with a decent belt for the inside.  But I read on the forums I think that leather is a good belt to use (or human skin).  This seems very odd to me and maybe I am missing something but is this really a good thing to use as a belt?  It would be nice because I could cut it as wide and long as I need and then sew it into a belt with some thread.  I happen to have some leather laying around from some crafting I have been working on.   Then as long as I am making this thread I was wondering what the best "tube" would be that the belt runs in.  I had considered making a plexi glass tube with hot glue to hold it together.  I think it could be cool to have a see through setup.  But I want this to work as well as I can get it.  So if a different material would work better I am open to suggestions. Also I will try my best to find my camera and post step by step photos once I know what the heck I am doing.

Extemely simple automatic emergency light.

I'd like some help to settle an argument regarding my extemely simple automatic emergency light.According to my friend, who installs emergency lighting, this circuit is too simple and has too many components missing but I say he's wrong, if one part fails it can easily be replaced. I'm not and electronics expert either.I'll explain the circuit...5v comes from a 5v 2A phone charger. Battery is a 32Ah 12v SLA. 12v charger is a smart charger with built-in status monitor.SPDT 5v relay rated to switch 12v @ 17amp maxThe light is a 12v 5 metre LED Strip with built in current-limiters and draws arount 2A.Basically, 5v powers the relay which means the battery is connected to the smart charger that keeps it topped up while there is mains power (240v here in UK). If there is a power cut the relay turns off and battery is switches over to the LED light Strip. Its that simple.It works as designed, no parts have failed and I haven't found any signs of over-heating. My friend believes it should all be one circuit and not seperate parts and is a fire risk as it is.He just won't let it go, so does he have a point or is he just being a/an _________ (fill in the blank, lol)? I've included a schematic of the circuit. Not sure if I've drawn the relay properly though.

Question about something in the Elegant Universe book I am reading...(KelseyMH?)

Ok, here it goes:   In the description concerning general relativity, the following scenario is depicted:  Jim and Slim are riding a "Tornado" ride (goes by different names, but essentially is a centrifuge that pins you against the outer wall and then drops the floor out from under you. Sometimes calle d PUKE machine). Anyways, looking at the ride from a bird's eye view, one measures the circumference and the radius and we find that the ratio is two times PI or about 6.28.  Now that is from OUR perspective, but from Slim's and Jim's measuring the circumference (so says the book) will give a different answer since they are traveling at high speed (assuming the speed is fast enough to invoke the Lorentz contraction).  Thus, he says in the book that his measurement will come up short and therefore not be the same ratio noted.  I don't doubt this, but I have a problem with not taking into account the lengthing of the circumference because of IT'S motion forward.   Am I missing something?   Why wouldn't the same effect  be proportional to the lengthening of the ruler used to measure the circumference, seeing they are traveling at the same speed?   Am I taking his example TOO FAR (in other words, he is assuming the ride is there but not physical)?   Maybe I over analyze?  :-)

Make supercapacitors from graphite in a DVD burner

The outline is that you can deposit graphite oxide (a cheap bulk material) onto a film of PET (the plastic used in Coke bottles), hit it with a commodity infra-red laser (such as the one in a $30 LightScribe DVD burner) and end up with a form of activated carbon material that can be used as the electrode in an electrolytic capacitor.  Add some aluminium foil, separator membrane and electrolyte and you've got cheap, robust energy storage.  The headline numbers are a few hundred milliFarads per cubic centimetre at a few volts, which works out to 1.36kWh per cubic metre of stacked capacitors.  It's still about 50 times less energy per volume than lead acid batteries, but you could store as much energy as your house will need overnight in the size of a garden shed or a set of bunk beds.  They charge/discharge in seconds and retain >95% capacity at 10,000 cycles so seem suitable for storage to even out intermittent energy generation from, for example, solar or wind power. I'm really thinking about cost here- unless I'm missing something fundamental it doesn't seem like producing these on a high volume roll-to-roll process would be excessively difficult, and the cycle life means the replacement time would be many years even in heavy usage.  Could you get sufficient kWh per dollar to make these a viable storage mechanism for home-scale renewables? There's a more informative article here.

Powering car LEDs via USB

Here's what I would like to do, just wondering if anybody can see any problems with this. I know very little about power or how electronics work. I want to be able to skip songs and answer calls without having to pick up my phone, for that I am going to buy this: https://www.amazon.co.uk/gp/product/B01E3UC59Q/ref=ox_sc_act_title_2?ie=UTF8&psc;=1∣=AP087GSGD7Y0R Now this will use my cigarette lighter for power which is fine until I get to my next part. I also wanted to put LED strips under each of the seats, and for that I would buy this: https://www.amazon.co.uk/Possbay-Interior-Atmosphere-Decoration-Sound-activated/dp/B017VSY3RY/ref=sr_1_3?ie=UTF8&qid;=1477573217&sr;=8-3&keywords;=car+accessories As you can see, that also requires the use of the cigarette lighter. What I want to do to get around the problem is buy this "1M USB DC 5V To DC 9V 12V" cable and also plug that into one of the USB slots: https://www.amazon.co.uk/2-1mm-Module-Converter-Barrel-Connector/dp/B01G56J4I6/ref=sr_1_2?ie=UTF8&qid;=1477573430&sr;=8-2&keywords;=usb+5v+to+12v.

Idling/stalling problems on 1986 Ford F150

I'm driving my brother's 1986 Ford F150 4.9 V6.  It sat, unused, for about a year before I started usuing it, and he didn't perform any maintanence.  Got it running in February and the biggest issue was (and still is) the carburetor.  It's functional, but only barely (apparently there was some bolts missing on the breather that weighed it down and stripped some of the bolts on the carburetor).  I took it in to the shop, and they did what they could without actually changing out the carburetor (I don't have the money to buy a new one, still).   I was told by the mechanic to idle the engine for up to five minutes, depending on the weather, to warm the engine. It's been working okay, as best as can be, but no huge problems. But then the heat riser on the exhaust manifold broke off on Thursday (I borught it back to them to look at, they said the whole manifold would have to be replaced and it'd take 4-5 hours).  Again, broke, so can't afford the $500+ they quoted, though they said it'd noisy but okay to drive until then.  Then, starting about two days ago, the idling got kind of clunky and it will sometimes stall out if I'm stopped or idling for more than a minute or so.  When I'm driving, it's okay, but slowing or stopping it can idle (I know keep one foot on the brakes and the other periodically tapping the gas). I really don't want to go back to those mechanics again (I get the impression that they're taking advantage of me being a girl), and if there's something I can do myself, I'd like to.  If there's suggestions or input of any sort, I'd greatly appreciate it.

What am I doing wrong with Lost PLA investment casting (aluminum)?

I've tried several times to get lost PLA investment casting to work, but it never turns out great.  In the photos you see an attempt at casting some 3D printed pulleys.  Interestingly enough, the one furthest from the sprue turned out the best, but there are still pieces missing and the details aren't as good as they could be. I used 6061 scraps for the melt.  I've tried adding a bit of boraxo/boraxo+salt.  I've tried without it. The mold was made by using 325 mesh silica and plaster of paris about 45 to 55% respectively.  This produced far better details than with play sand, but still not great. After casting the mold I let it sit for 12 hours or so, and then baked it for 2 hours at 350 F, and then 2 hours at 500 F (upside-down), and then put it in the propane BBQ grill for 2 or 3 hours at max heat.  I then blew out the ash using a can compressed air.  In this photo I even kept the mold heated until just before pouring, and then I put it into the furnace until the top level of aluminum re-melted. You can see that I have several vents (2 for each pulley) and a very large sprue.  The sprue fills quickly before anything comes out of the vents. Once the aluminum melts I set a timer for 3 minutes and allow it to continue to heat before pouring. Any advice is welcome from those with experience.  Also any photos or videos of how you've made it work would be great! The pulley's I've printed are from http://www.thingiverse.com/thing:343343.

Help Me Establish Gas Station Fraud- By Exposing Fuel Manipulation.

Prelude:Every week I only ever travel the same route, at the same time, with the same amount of traffic on the road.I fill my cars fuel tank once a week, with $50AU of petrol.The prices lately have been stable and around $1.30AU/LWhat this post is about is the fact that due to me travelling the exact same Km's per week, I have noticed a significant difference between the two petrol stations fuel that I fill at.Can anyone educate me as to why when I fill at one station I get 8 days of travel and when I fill at the other station I only get 4 days of travel?Once again I am filling the same amount of fuel at each station, just one stations fuel (Major corporate outlet) seems to be of a much lower quality.Is it possible that something is a-miss with this situation. Is there a variable im not considering?After 4 months of weekly refills I feel that conclusively, one stations fuel seems to combust better than the others.Is this possible and if so are there any home experiments I could try to prove my theory via testing the fuels combustion/quality.I only write this as I sit here on a week, where I was forced to fill up at the "suspect" station. Im on day 3 now and my fuel is red lining... What is happening?I know the difference of 3 -8 days is a massive, surely others would have noticed this also. I thought I was mistaken the first few times it happened. But now I am positive, something is wrong.I might add, I use premium fuel with the same octane level at both stations.Could that be it? Would they be mis-quoting the octane level in their fuel? That is the only thing I can think of.

Recumbent cycle: "blue sky" design query

I am not one of nature's cyclists. I didn't actually learn properly until I was in my twenties. My bike is very old, very rusty and very, very heavy.However, I feel that I "ought" to cycle more, for shopping trips and the like. I quite like the idea of switching to a recumbent, but they are expensive (current available funds: zero).So, I'm playing with the idea of rebuilding my mountain bike into a recumbent (and learning how to weld on the fly?).In the sketch below;The black section is the back of the old bike, turned upside down.The blue section is the front of the donor bike.The red part would need fabricating somehow.I haven't thought properly about steering mechanisms, but probably under the seat, via cables to arms welded to the forks of the will-be-the-back wheel.Would the bike, as I have sketched it, in principle, work?I'm bothered about stability, especially at take-off and landing. Am I worrying unnecessarily? I have access to a second donor cycle. Is there any mileage thinking about "doubling up" the blue section, to make a trike? Not massively wide, but I could add luggage space, or an extra rear-facing chair-style seat.Brakes: before I cut up the bikes, am I right in thinking that I just remove the cables and levers from the handle-bars and add them to the under-seat steering?Gears: the donor bike is a mountain bike, but I never used all the gears anyway. This area is pretty flat - can I get away without any gears?Coasting: although the back of the donor bike ends up upside-down, it is still turning the same way, so I can still coast OK.I'm sure I've missed something obvious...Anyway, even though I've not decided to do this for certain, I'd appreciate any comments or thoughts.

The Large Hadron Collider: is it worth it?

The Large Hadron Collider(LHC) is to be unveiled this year. It is designed to solve the much talked about energy crisis, and hopes to do so, but can it be worth all of it? From Wikipedia- (On October 25, 2005, a technician, José Pereira Lages, was killed in the LHC tunnel when a crane load was accidentally dropped. The construction of LHC was approved in 1995 with a budget of 2.6 billion Swiss francs, with another 210 millionfrancs (€140 M) towards the cost of the experiments. However, cost over-runs, estimated in a major review in 2001 at around 480 million francs (€300 M) for the accelerator, and 50 million francs (€30 M) for the experiments, along with a reduction in CERN's budget, pushed the completion date from 2005 to April 2007.[14] 180 million francs (€120 M) of the cost increase have been due to the superconducting magnets. There were also engineering difficulties encountered while building the underground cavern for the Compact Muon Solenoid. In part this was due to faulty parts lent to CERN by fellow laboratories Argonne National Laboratory or Fermilab (home to the Tevatron, the world's largest particle accelerator until CERN finishes the Large Hadron Collider). [15] The total cost of the project is anticipated to be between US$5 and US$10 billion.[2] On March 27, 2007, there was an incident during a pressure test involving one of the LHC's inner triplet magnet assemblies provided by Fermilab and KEK. No people were injured, but a cryogenic magnet support broke. Fermilab director Pier Oddone stated 'In this case we are dumbfounded that we missed some very simple balance of forces.' This fault had been present in the original design, and remained during four engineering reviews over the following years.[41] Analysis revealed that its design, made as thin as possible for better insulation, was not strong enough to withstand the forces generated during pressure testing. Details are available in a statement from Fermilab, with which CERN is in agreement.[42][43])

The Moon - What do we really know and what is possible?

If we look up then seeing the moon is the most normal thing to us there is in the sky.But did you ever wonder how it actually got there? ;)Theories are out there by the lot, including those from real scientists.One of the most common is that it all started by catching the thing and that all was perfect at the time.Over time the orbit then stabilized.Other theories include that formed when our planet formed..What they all lack is what is common and true for all other moond out there: These rotate.According to science an object the size of our moon would need to rotate to maintain a stable orbit.No one told this to our moon, so it just stays in a stable orbit anyway.The only other accepted theory, that funny enough never mentioned OUR moon, is that the center of mass must be facing the orbiting planet.Now theories can run and wild if you let schientifically people loose on a subject.Official NASA data obtained by monitoring equippment on the moon supports the theory of the center of gravity.You see, sesmometers recorded "moon quakes" but also the impact of burnt rocket stages - the later were dropped on purpose.At first everyone agreed the equippment must be faulty but going through it again and again confirmed all works fine.So what got them so exited that was never officially made public?You see, every thing with suffient mass will create a sesmic shock on impact.On earth we can located the source of an earthquake or even explosion quite accurately.Same happened on the moon only with one difference to earth.Every impact caused a ringing effect.Like a bell, the soundwaves and shockwaves traveled through the moon for very long times.An early explanation was that the moon is made from really hard rock or that it might even have a metal core.This was rendered useless once the actual mass was calculated and it turned out the moon would rip us apart while spinning around us.The term "hollow moon" was born.Another interesting thing happens when you try to track down what equippment was left on the moon during which specific mission.Everything up there must have been installed at some stage.For some things though it seems there is no record when or where exactly something was left up there.Then there is the thing with the interviews...If you check the fuzz about the first moon landing then back then you couldn't help yourself but got exited as well.None of the three astronauts however appeared to be at least a little bit exited about going where no man has gone before.Somehow like visiting Iceland for the first time only to realise someone was there before you already.But it was the moon, not some easy to reach island...And while up there we did not see any exitement either, like fully staged and planned ahead.Like a not so 100% school rehersal.Claims that it was a fake and actually filmed in some studio have been verified to be false - they really were up there.After they came back two went silent and refused any interviews about the moon.All three though never spoke about anything we did not see on "live TV"...All the missing segments, the drop outs, the silence during communications...The money...Apart from the Pentagon making a disappearing act of 6Billion US, the already planned and staged moon missions were cancelled with no valid reason at all.One mission already ready to go to the launch pad, crew fully trained and briefed.Two more ready for final assembly.Official reason back then was "We have been there, it is time to explore new things."Almost the same statement was made by Obama a few weeks after he claimed "We will go up there again!".If you take away the costs for the abandoned missions then the money blown up to the moon has a huge difference to what can be tracked back.The lost sum equals out to about 8 more moon missions plus tons of state of the art equippment (back at the time it was state of the art).If you add what the Pentagon lost we are close to 15 more missions.The now...A few years back a lot of previously declared top secret documents have been released to the public.What was a good idea however turned out to be a bit too much.Quite a few documents were included that provide missing links to "incidents, missions, money spent"...Within these piles were documents indicating that space missions of the same extend as the much later moon missions were made.Same rockets, similar crafts, same requirements for water, food and oxygen, some though with just payloads of oxygen and water.Mind you though the documents speak from proposed options and not planned missions.And none of them had any exploration within it, just deliveries if you don't mind the comparison.Those documents about the ringing of the moon and how this would impact on the things we assumed to know about the moon were in there as well.What is really interesting though is what came back from the moon.None of it actually indicate that there is suffient ressources up there to justify mining.Funny enough exactly is planned on a military style.Seems fair enough considering the military can provide the best people for such a hard job.Some normal miner might have no problems getting under ground every day but knowing he is on the moon and might never make it back is another.With all the probing done that we know of you would assume the planned mining operations would be in an area rich in minerals, metals or at least something to generate fuel or oxygen.But no, it is planned to happen "on the dark side" and in an area that appearently was never explored in other ways then taking a few blurry pics while flying around the moon.However, both Russia and China claim to have been very close to this area long before details about the mining became public.And that brings us back to the past and what astromauts stated or to be precise refused to confirm or deny.In some videos we can see movements in the background.In several adio stream we hear the comments to what happens in the videos.If there is light moving around then it does not matter that is blue.You just wonder what it is and where it might have come from.Imagine the surprise if then in other videos you hear things like that the lights are back or that steam comes out of the moon like a gysir.There were official explanations for the first sightings made by the normal people when watching those videos on the NASA websites.Soon after the videos disappeared from the servers.Copies were made by the curious and quite a few videos were identified later to have contained "sightings" as well.Some even show what appears to flying machines with great manouverbilities.And if you take the high point of the happenings then it is also the same time when it was decided that we actually have no real interest in the moon.Astromauts later denied to have ever made any comments like that they are being followed or "escorted" by another craft.And the same Astromauts many years later still refuse to deny or confirm that what we could see and hear during their mission videos actually happened.Don't get me wrong but if the deny it then it just means we all saw some refections or such things.If the confirm it then we know something was out there with them.Doing neither usually means what we saw is ture enough to deny any knowledge about more details.Why then the sudden interest?Trump wants to get up there, military mining, private companies not to forget China.If there is nothing at all up there then why would they all spent money that could provide a much better living for those with low incomes?Even if it would be just for new schools and hospitals the money would be better spent if we trust the official claims about what is up there.The not so official claims....We already know NASA does not want to come with an official explanation why the moon sounds and reacts as if it would be hollow.Same for any video, audio or picture evidence indication there is sturctures on the moon or activities.Here is some of things that other people of great knowledge and with nice degrees under the belt say could, might or even is true about the moon.1. We have no evidence that the moon was always there, only what we have in record throughout history.Some claim the moon would be an artificially created structure.Indications of techonlogically highly advanced civilisations before us are there.And mining out a tiny planet and placing it in earths orbit is not far fetched if you consider higher technology levels than what we currently (officially) have.2. The satellite claim.Like the Death Star our moon could be an artifical satellite placed there for a purpose.What speaks for that theory is the impact craters on the moon.If it was never spinning or better rotating around all axis then a lot them would have been impossible.A crater always shows to some extend the direction of the impact.And on the moon they all apear to be direct and straight hits only.And even at some proper angle that against physics did not create a corresponding crater: Our plant would have been in the way.Officially it is claimed though that there would not be much of a directional crater because of the missing atmosphere and all debris settling evenly.Debris however does not explain the deformation from an impact at an angle.The satellite claim would also explain the missing depth in the craters.By the size of the bigger ones the crater should be much deeper and as said show some direction.If however the rocky surface landed there over time or is just the remaining natural hull then the craters could no go deeper.No advanced civilisation would design a stationary satellite that get a hole as soon as some big space rock hits it...3. Undocumented missions.If claims are true then we have been up there a lot more times than what our history lessons tell us.Tiny probes to analyse things, send data and so on are a thing not the the USA did.If you explain the reason for collecting seismic data by wanting to document an impact of an astroid then it is a joke.Sure it would be possible but what could we learn from the data?Nothing unless you consider that in some unoffial missions drilling was attempted on the moon.Sample collection to evaluate what is in the ground of use for future missions.Some documents now claim that all these attempts ended prematurely.Drills failed or broke, drill heads failed to go deeper and upon inspection were totally worn out.And all seemed to have happend at around the same depth.Although there is no atmosphere on the moon - if you stand on it you would be able to feel vibrations of the surface.Something astronauts would have felt during the drilling.And you can feel the difference between a vibration ending by stoping the drill and one that keeps going for a long time after...The dark side is visible in quite a few school books.Looks like the front with the brightness corrected just with different craters.Ever bothered to scan these pictures in and use some software to find matches to craters on the front of the moon ? ;)Anyways, those images show us the moon as near perfect sphere.What they don't show is how the images were actually made.They certainly did not use massive search lights from orbit to provide light for cameras.Means other sources were used, like IR, Radar, Microwaves and so on.Like we found the ruins of old civilisations by using satellites that can "see" through the forest and soil.And with that it would certainly be impossible to create such a nice and detailed image like we get from the front side.If some is edited, then why not all of it...And if all those missions we don't really know about also landed on the dark side it would explain a lot of things.All sightings seem to have disappeared to the dark side.And all leaked informations about previous missions before our first landing idicate the interest in the dark side was actually huge.They all ended though with one mission report claiming to have spotted lights on the dark side.Moving and stationary and when trying to get a better look by adjusting the orbit for the next round those lights were all gone.But audio recording indicate that from that moment on the astronauts were no longer alone and followed until turning back to earth.Several attempts seem to have been made to land near sightings on the dark side.Those where the astronauts returned home the never were the same again.Documents claim long treatment in mental facilites or suicide.The official missions appearntly started with the backstory of exploring.Some now claim it was attempt for a peaceful presence that still was not tolerated.4. Stories from involved companies.Even if NASA builds a craft themself they still need the corresponding supplies.And for a lot of things they are made outside by independent companies and contractors.Trying to track down early space mission again seems to confirm all claims about previous missions.The amount of materials provided would otherwise mean NASA actually crashed the majority of things right after take off without anyone noticing.5. Launches...So far all claims about previous moon missions or just secret ones were denied.I call this "plausible deniability".In all statements it is refered to the official launch sites.Things like being in public view and so on.What is not that commonly known is that there were a lot of capable launch sites available.After all big rockets have been tested in secrecy since we had the first.The claimed landing of the chinese started a big conundrum.At first the US claimed it never happened because there was no rocket that went up.Images prived by the chinese however clearly indicated the opposite.Not much later it was noticed that a few launches might have been misinterpreted as missle tests....What does that really mean?Quite simple: The surveillance is not perfect if the other side insists that it happened.The plausible deniablity is gone.If the US was "forced" to confrim they actually noticed the launches then it also means the chinese claims about the US doing the same could be true as well.And wasn't it a very important thing during the cold war to know when, where and why the other side launched anything?The silent agreement not to go up there again was broken many times...And although most if not all of these mission ended in orbit only it makes you wonder.What would be big deal even if all claims and conspiracies would be true?A hollow moon would defy what we know about how the universe works.With that it would also contradict some of solid laws of physics.So we need(ed) proof.Assuming we had that for a long time already then it leaves the big question of why it is hollow.Natural or artificial.Nothing natural would make sense so we investigate further.And if people still claim that they can use their little equippment to every now and then hear transmissions from the moon...Sure some things up there transmit data all the time but they do so on common frequencies and not in a range that is and never was used for long distance communications.The interest in the mon came back with our modern technology.We have watches with more computer power than what was used for the old moon missions.Materials and manufacturing methods that provide much safe crafts and space suits with a fraction of the weight of old designs.And we have new means of taking more or less limited energy up with us...We are prepared so to say.No matter what really is up there, no matter if it natural or artificial, just the fact that the moon is hollow changes our views on a lot of things....What do you think would be the best explanation for the data showing the moon rings like a bell?

Printer disconnecting or USB port disappearing in Windows

First I thought to make an Instructable out of it but realised there are too many different printer models out there, so this time no images. What is this about you might wonder? Well, let me tell you my story first and you might see similarities to your problem. It all started with me getting a new PC as the old one got memory problems (RAM modules failed). After a few successful prints I noticed errors coming up in the log window. Mainly things like communication problems and that some data is sent again. Realised that on my new PC I did not check the speed settings for the COM ports, so I adjusted them to match the printer board and moved on without even bothering to check the logs. Then, half way through a bigger print, it all stopped and I could not even connect to the printer anymore. After a power cycle on the printer all was fine again but the error kept coming back every now and then. At this point I started to read up on the problem and the most common recommendation is to print over SD - too bad if your printer does not support it and too bad it does not address the issue at all! A few more technical answers pointed to the Logitech drivers, especially mouse, keyboard and 3D vision. As I was using the same outer hardware as before and also the same drivers (and same version numbers) I simply ruled this one out too, although it might be a vital clue for others. When starting to get frustrated and after opening a cold blonde I remembered that I had a similar issue a long time ago and that it was related to loose wires on the screw terminals for the power connection. Measured it all but according to my trusty multimeter all was fine. Now comes the fun part: I friend of mine with a HiFi fetisch was here when I testing the connection and he started laughing at my attempts. He explained that ALL his connections, no matter if power or audio signal are oversized! Here I started to wonder if he is up to something and looked up similar circuit board mounted power plugs. To my surprise they are all rated for anything between 1 and 5Amps. Even without a heated bed powered by the printer board I think everyone will agree that a max 5A connections is not enough. My frined then offered to check the plug and connector at his place - what a great thing to have friends :) He used a signal generator and small speaker with the plug as a connector between them. With an oscilloscope connected to both input and speaker you could see, while moving the plug, that the audio signal become somehow unclean - there where spikes and missing bits everywhere depending which way you wobble the plug. After taking the whole thing apart the destructive way we saw the cause: overheated contact areas with discolored surfaces. I replaced the plug now with a 250V/20A one from an old laser printer and had no USB or connection issues ever since. Ok, what's the thing with power and USB problems on a 3D printer? Almost all printer boards have the ground connections bridged to avoid interference on the USB signals. This mean, in case of a faulty power connection or one that is "dirty", the USB port on the computer can receive back EMF signal or even a voltage spike. In return a smart bios either disconnects the port or disables it until the problem is solved, in our case by restarting / reconnecting the printer. But even with no obvious signs of power problems you can get  a so called "dirty" connection. Dirty covers all from corrosion, worn springs for battery compartments, overheating or in the old days burnt relay contacts. For our printer it usually means that either the soldering connection on the board or a screw came loose, in rare cases like mine an undersized connector can burn out due to being unable to handle the currents. The bad thing is that you can not always spot these problems the easy way... Is there an easy way to tell that my USB problem is caused by a faulty power connection? Yes and no. Some boards offer indicating LED's, you connect power and the LED stays on even if the printer is disconnected from the PC. If it is more than just a Power on" indicator" this LED will be off after the printer stops working and in the device manager your serial port for the printer is gone. You might also hear the warning sound from Windows in regards to a device being disconnected. If all the above is true than most likely your power connection has a problem somewhere - if in doubt replace all screw and plug connectors for the power. Sometimes the problem is less obvious. Your print software might show communication problems in the log window or re-send a lot of commands. If the speed selection for the com port is the same as for the firmware of the printer board and as set in the printer software, it could also be a power connection problem. But to be on the save side try a shielded cable with ferrite cores on both ends first for the connection between computer and printer. Can I take any measures to prevent the problem? Sure, you could solder everything and make sure the wires are fixed in place so they won't move. But a simple indicator might be enough: Solder a piece of LED strip to the power connection on the circuit board - if the connection has trouble the LED's will show it in most cases by changing light levels or flickering. On top they act as a nice light to see what's happening during a print.

Repulsine - the great mystery...

Even before the repulsine saw some attention during WW2 there were sightings of what we know call the classic UFO shape.Be it in Austria, Poland or other places in Europe, people reported weird disk like thing with a dome flying around.What leaked in images and documents after the war shoed that the repulsine looked basically identical to what people saw as a UFO in the sky over big parts of Europe.Then again, the repulsine appearently never made it a usable stage, same for most jet fighters at the time and still they flew around...If we now just take it for granted that actual test flights really happened back then you might wonder why we did not see any after the war anymore.For most critics it is a simple sign of facts and "confirms" that the replusine might have been a nice idea but never anything that really left the ground.As said, I often like to dig deeper and in this case the digging took far more years than what I planned on.I can not provide any solid proof for the following but I am sure even a sceptic will come to similar conclusions after reading it.Try to find some "eye witness" reports from people who saw the so called "Roswell UFO".Yes the one that made Area51 so secret and famous...Reports can be boiled down to some essential features of the hull, for those who saw it proof that it is alien.Three distinct round shpes on the underside, like you add the bottom of an egg to a round disk.Said disc of the bottom was also shaped like a wing, or the flying disk toys our kids like to play with.On the other side the shape grew up like a half shphere with an added cone or round top on it.On these area they claimed to have see engine outlets or similar and appearently the top cone was spinning in another direction than the rest of the UFO.Now I am no expert for Roswell but if I leave area and time out then I could have been fooled to think these people discribed exactly the same thing people saw a few year eariel flying over Europe.The Roswell UFO was not from another world, just stolen from the looser of a really bad war.What was seen was a working Repulsine, be it an original or something the US created from the 5 prototypes that disappeared after the war.Ha, ha, good one, then why don't we saw them flying after this anymore?Well, for starters it was a testflight gone wrong.Presumable it was planned to be limited to Area51 but the pilot lost control.Considering the Nazies appearently did their best to kill everyone involved in the project before the aliies arrived it is no big surprise.What that test flight would have shown is the impossible manouvers people already witnessed over Europe.90° or more turns at full speed instead of making a turn like a plane, sudden changes in alitude as well as accelleration on a level that makes even modern rockets blush.And if it really was the first bigger testflight they did it explains the big secrecy about the Roswell incident and what followed and created Area51 as we knew it.A "weapon" capable of these things would mean total dominance and options to impove planes and more.So why did they not even do that - or did they?The repulsine was created based on what we call today fringe- or pseudo- sience.If there is only one peroson, or a few that can even understand the claimed working principles that it can't be science as we know it.So, lets take a look what things were already heavily used in the repulsine that "we" claim to have developed or discovered decades later.Coanda effect.When air travels over a surface then it will follow the surface.You can try this with paper strips and blowing on them as well as a stream of water and some shaped objects.Long known but never found any real use until the military picked it up.For example air inlets were then developed to utilise the coanda effect.Remember how a lot of them these days look like a ducted fan housing?The round and slightly conical shape of the inlet will actually act like an airfoil and provide lift - of pulls forward in the direction of the air flow direction of the engine.I supercars we use it to create more downforce and better aerodynamics.Venturi effect.Again a very old one but funny enough also a major factor to make a jet engine work.Tesla turbine.In the Repulsine the rotating copper disks acted like a huge Tesla turbine by using a similar effect.The space between the disks got smaller and smaller towards the outer perimiter.Due to the fast rotation the molecules were accelerated and this created a partial vacuum.We use these principles today for specail vacuum pumps but also in military applications.Harmonics.Without harmonics and resonance the Repulsine would have been impossible.And at a first glance it seems we never made any use from that bit of the machine.Then why do we design exhaust systems in such a way than already the extractors ensure a pump like action and controlled backflow?The sound a good exhaust makes is also based on using the harmonics created by the explosions in the cylinders and expanding gasses.We learned that it is far more efficient to use harmonics and resonance in an exhaust system from somehwere ;)Plasma.The repulsine was said to have emitted a bright glow during certain movements or speeds.To create plasma we need a lot of energy, not so much however if the plasma is a by-product anyways.We learned that a high enough voltage differencial in a vacuum can create a nice plasma arc.From there things like analog TV monitors were created.But we never made anything that creates plasma for any use in an atmosphere.Well, unless you start to check supersonic rocket engines and other things.The working principle is very, very close here in some applications like the ramjet.Vortex energy.Today we see all vortex energy stuff as a free energy scam or at best a waste of time.But from the inlet to the outlet the entire Repulsine utilised what we now know as vortex energy, vortex math and so on.The air is twisted and spun around so many times that it is hard to keep track - but it always happened in a harmonic and resonant fashion.In some way this is implepemented in very expensive cars to keep the ventilation system almost silent even at full power.If you ever take an expensive car apart you might wonder why the air system is not as smooth and straight as you would have expected to get this silence ;)There is more but the list would become too long ;)So, if the repulsine was really that great then why was it taken apart to only utilise fractions of it in other things?If you have something really great that combines a lot of things then no one would suspect if you "developed or discovered" some of it in other projects.And to give you a very bad comparison for the other way around:If you know how to combine a petrol engine with some long blades then you could fly!I know, we did that already but you get the point.I can give you a motor and blades but that would not mean you could build a plane or even helicopter!At that time and still today something like a Repulsine would upset the "balance of power".If claims are correct then the engines of the repulsine were only required to provide the enrgy for directional changes or speed but it flew on "free energy" as the main engine system.In lame words like a jumbo jet that only needs a small engine for the hydraulics and electricity...Another big problem is the replication even if you would have a complete and working model to disect.You see most parts were brazed or welded as screw or rivets would have been problematic in certain areas.Other parts like the Kudo horn like intake systems would even today pose a challenge if you want to replicate them 100% correct.And if your understanding of science and physics greatly differs from those who originally created the thing...If your understanding tells you a dice has 6 sides (we all know that) but in my understanding it would have 16 then you would never understand how my dice rolls ;)Bringing true free energy of any form into this world is only allowed if someone can still make good money from it.Just check solar cells and wind generators - we all can have them but our providers make sure they have enough of them as well ;)Will we ever see a fully working Repulsine again?Of course !Some people like old cars, some collect old planes or old machines and tools.A great project for people in the right trades is always to build thier own little steam engine.So to say as a reminder of how it all started.Same will happen with the Repulsine as the first really utilised free energy machine the world had.The war and killings were not what really scared the world.This happened and will happen over and over again to various extends.Really scary was once certain people realised what might happen if over there the war would end with a victory and people would have time to develop for peaceful things instead.Without the war or this idiot Hitler a peaceful war would have taken over the world by storm.Those making sure we know nothing else but paying for our fuel and energy would have lost their monoply.Times change though...We destroyed our world with our needs for fossil fuels and electricity.What is left we destroy by chopping it down, digging it out or just by building new estates on prime farm land.People are now more desperate then ever to find ways to reduce their energy bills or enviromental impact.Otherwise Google wouldn't make billions on all the fake free energy videos out there.But what would it take to recreate the Repulsine?The person able to come up with the understanding of at least attempting to build one again would need to have certain qualifications and titles.He or she would hold a Nodel price for completing some of our known laws of physics or for finding some of the still missing ones.It would be a quite hard to understand and like person too, maybe even highly autistic.The person would also have an addiction like need to complete things, add the missing bits.And of course a totallydifferent understanding on how nature and the universe work.David T. from England is such a person, or at least the closest mankind can offer so far.He can see math in his head as shapes and images.Complex math problems appear to him like developing landscapes in high detail.He even learned to speak icelandic fluently within 7 days!!Imagine such a person would develop an interest in the old pioneers like Schuberger, Newman, Tesla and so on?Where we normal people fail to see any relevance or connection a guy like David would be able to literally see how all these inventions and ideas connect.He would be able to SEE the math behind it!Knowing how something was supposed to work and combining what is known through patents, drawing, videos or reports would enable such a person to make conclusions.For example where we might just see a nice pattern when we throw a stone into an undsturbed lake such a person would also already know and see the corresponding math the created the waves and why they were created exactly like this.Assuming David has no real interest in such things, then is it possible others already try?Sadly yes and even worse they do it with kids.Learning methods that are different can bring great results.For example while we use a calculator for big numbers some kids attend really strict and performance based classes to do this with an ancient abacus!After years of hard and often painful training they are able to it with a small abacus that only has a single row of discs.Shortly after they graduate to a virtual abacus - they only twitch their fingers in the same motions they would use on the real thing, but the disks and rods are all just visualised in their heads.That however is all meant as an improvement and the kids do it because they want to and not because they are forced to.Like learning to be a chess champion before even being old enough to work...In china however we have a very selective education program.Kids are not just trained slightly different to our kids but also closely monitored on their progress.As soon as one stands out for some skill it is subject to examination.Being well above average here means it is an opportunity for the kid and the parents - on paper at least.We in the western world would see it as a viscious circle though.Over the years china developed not only a better understanding of how these special kids brains actuall do their things but also how to create tests for this purpose.What looks like impossible or nonsense to most kids will trigger a scecific response and understand in those that are special.We would create something that allows parents to know early on where the kid has really good skills and what activities should be promoted.In china though the parents receive a nicer flat or some additional income while kids are send to a far away school.Again we would refer to such a school more as a boot camp.Discipline is at least on military levels, same is the punishment system.In most cases families are not reunited for many years, phone or even video calls only happen in the rare times when western TV crews are allowed a sneak peak.I just say: If a kid would see the parents often enough then it would not only know what to talk about but also be happy to talk to them - this however you won't see.It is like they talk to some distant uncle or such.What is really scary though is how these kids are trained to see their purpose and how important it is to be the best in what they do.Imagine you lost your kid at an early age and the only thing you got over the year was letters from the government saying how well it is doing and that you can be proud of it.Then it graduates and you are not even allowed to be there on that day...After that the kid is gone for good, you get a new flat and your proud kid supports you with some nice extra income.You don't get to know where it is working, what it is doing or if it might just be attending some university.By any standards these graduated kids can be seen as a great number of genius young people.Math, music, languages, science, you name it and they will have the experts aged below 20 for it.But what do they do once school is finnished and life starts?So far no reporter or family was able to figure it out.Means they don't appear in some high profile company, they don't start a successful business or teach at any public or private school.I leave it up to your imagination where thausands of kids find secret employment once they graduated....If, at least in theory we could be able to understand all these old technologies then why don't we at least try?Everyone has a goal, some desire a happy family and nice house, other need fame or just money to be happy.With that comes greed.You might have a really nice car but that does not mean you would give to some neighbour for a trip.Even if it just a nice rose garden, you might not want to share the views with anyone.This is true on all levels and we created a term for it "Need to know basis".If you just operate a press in a factory then you don't need to know when or what the next job is that comes for your press.You will know when it arrives and can check the documents attached.You don't need to know that your council is expanding and it is only seen as a courtesy to let you know on some notice board or in the local newspaper.And even our government does the same.What we do from the first days of our new baby we do on all other levels in the same way.What the baby does not need to know we won't tell or show.But we provide all the littly anklebiter needs to develop and be happy.Changing nappies, feeding, proving comfort when sick or having a nightmare.Later we teach language and other skills like walking.It goes on as you know...Humanity as a whole is like a little kid as well.If we would know all the little, dirty secrets then we would riot and go mad.Things that are of no concern are nothing we need to worry about, so we don't get to know them either.Knowing how build the latest fighter jets is seen as a thing that would give a possible enemy an advantage.Makes a lot of sense to everyone as these things might have to protect us one day.The questions that remain are:If humainty is a child, then how old are we now or when do we graduate?If there is a collection of secret and old knowledge then who owns and controls it?What would it take to force the release of all the things people actually created for a better world and not to be locked away?As funny as it might sound but one answer to all these questions would be to do nice orund trip in your Repulsine.Fly over ever single country in this world.Let their guided missle and what not chase you and once enough show then how quickly you can make a 180° turn to get behind them.So called unimportant countries might ignore you and the people only enjoy a nice show.Those powerful enough will fear you and think it was "the other side" showing their superiority.Once done with your round they all will have to realise there is a new power that is at the helm now: Knowledge and understanding.No more secrets, a repulsine for everyone who wants the plans to build one.A new world would start.Ever thought about that when wondering why all these "Aliens" we see in their ships in our skies never land to say hello ? ;)Even if they would be Aliens and not just some human pilot in some experimental craft:Shouldn't this demonstration of absolute power and control without any violence tell us something?The Repulsine need to come back to life to end all this UFO nonsense and Alien theories out there.You hear the sounds, see the ligh show and impossible abilities.And suddenly most if not all UFO sightings would have a common factor again.Just because the Repulsine is claimed to be lost and that it never actually worked despite film evidence showing the opposite does not mean there is no one using the technology.A working Repulsine available to everyone would also kill the doubt on so many other old inventors and "fringe" scientists.Science and physics would need to be redifined as would be able to find a lot of missing links.I know there is not only a lot of people out there trying to get what they can about the Repulsine but also that there are others who try to prevent this.You have a really easy time getting permission examine some old and histrically important artefact from a museum than getting just a hands on approch for what remains of the Repulsine in various places.Not even decent 3D scans will be allowed.Anything like just getting a tiny pipe cam inside is rejected with the excuse it could cause damage.If the thing is a hoax and never worked then why would it be so important to never touch or move it? ;)I recently got word that two of the remaining Repulsine "artefacts" were examined by the same group of "scientists".This happened in the late 80's and said scientists were claimed to have had acces to a collection of spare parts for the original Repulsine that was lost after the war.A private collector was also mentioned who denied all access but what he had in a secure storage facility appearently disappeared shortly after his refusal.Putting all the dots and hints together it would mean that someone in the late 80's was able to get literally everything that is left of the project in his hands.Those who claimed to have seen these scientists working on the Repulsine leftovers claim they used top notch technology to do so, including 3D scanners - and those were basically imossible to get back then for any uni out there...The laptops used were said to use touchscreens and were connected to all sorts of equippment.And they did it in almost total silence, like a group who studied a performance many times and knew exactly what do when and where without the need of many words.Professional in examining something unknown all all possible levels.I was unable to get any information on these scientist or who they worked for.But if you are one of them and readin this then I would love to hear from you!
