Your thoughts on "UFO's", strange things and the unknown

Don't take what comes below too serious please ;) I thought for the start of the new year it would be fun to talk about things we take for granted or that we would call nonsense. You know topis like those provided by Erich Däniken and other that think outside the conventional archiological range. Modern science has provided us with new insights into very old stuff but also a new look on things we thought to know better anyway. Here is some food for thought: 1. India... In this beautiful and old country it was discovered that hundreds if not over 2000 years ago people used lathe technology on stones. For example to make pillars with a weight over a few tons... Chains were created from molten rock and in many areas you find polished stone that even after hundreds of years still has a mirror finnish. Some of these creations are claimed to be made with hammer and chisel but how do you get a displayed accuracy that even modern technology struggles to provide? I don't want to clutter everything with video links but check Youtube and you will find temples in India showing musical granite pillars and chambers carved into solid rock with a precision that seems impossible! If that long ago human knd already knew about gear systems and lathe technology, then what else have we lost over time that we now claim as new technologies? How could anyone polish an entire granite hall and a big one that is to a mirror finnish? 2. Peru... Apart from being full of archeological wonders there is also the impossible to be found. The Nazca region shows, in aerial views, kilometer long and perfectly straight lines. In other regions, also in other continents, we can see images of strange people or artwork - again only from high above ground level. Some of the artwork is only in correct proportions and with proper contours if watched from a very specific angle to the mountain in question. The kilometer long lines are not simply on standard mountain faces but instead on top of mountain that have the top removed to be perfectly flat. And even with a lot of posible options to interpret the lines they look like any other huge, modern airport landing strips - including runways and tracks to areas we would call terminals or service bays. You can ignore all possible ways to interpret the design and possible use, what you can't ignore is the missing mountain top and level of accuracy on such a massive scale! 3. Pyramids... On all continents except Australia we find pyramid structures with very similar features in terms of proportions, angles and the way the face in a certain direction. In Egypt they just recently found another hidden chamber... Tunnels, too small for a human to fit point to stars and star signs. Some of the tools used to create were found with the help of small robots but also that some seem to be quite modern in age. Did grave robbers use them at a time were it is beleived that such tools were impossible to create? Or could they be as old as the pyramids itself? In south america we find pyramid structures looking quite similar to those in Egypt - why so similar in features and appearance if there was no contact between the two civilisations? To make things worse some of the Inca structures show tunnel and channel systems "leading" to the pyramid in question. Classic thought is that they were like tunnels to direct water or provide access in the beleive the jungle was not removed to hide the complex. Makes no sense if you see the city like areas that are now exposed and studied. I mean: how would created a city in the jungle without removing the trees?? What could make you wonder is a simulation that was performed several years ago. Based on a computer model in 3D different theories were tested. Irrigation was ruled out quickly, same for access routes or secret tunnels for the priests. One funny student got bored and decided to play god. Assuming the Inca priests would call their gods in the sky temple to provide rain he let a monsoon go down on the pyramid. The result was unexpected so he showed the results to his companions and they did the same test agin but simulated a massive airflow going down directly on the pyramid. Turned out the flow would be directed away under ground with more efficiency than systems Nasa uses today for rockets and space shuttles... Mind you the tunnels are far from straight and without this simulation it was trusted that they could not do this stuff... We now have rocket technology that uses surface direction and vector control. The square and flat designs leave a void insight that pretty much perferctly match the angles of those inca pyramids? Apart from pure coincidence, what could be the reason for this match in shape and angle with a tunnel system perfect to remove hot engine gasses? Ok, I admit, not all continents, the pyramids in Bosnia are just a hoax, so Europe is out of the race ;) Sorry Semir :) 4. Artwork... Be it here in Australia, the African desert or America - we find images of mystical people or rulers that could make you wonder. Again modern tech in the form color filtering, desitity readings and 3D scanning provided us details unseen before. If you think of gods in very ancient times and try to imagine you would be a native: What do think how many different images of their god could 100 people imagine? Let's agree it would be plenty... But if we study artwork in caves and rocks from around the world we find similarities that IMHO can't be explained. Many show features that, compared with modern technology, could be mistaken for helmets, gloves or even manual control systems. Others show things thought to be as simple as pine cones to resemble modern milling or finnishing tools. Again only possible by enhancing details the naked eye won't see. With no contact to each other and often thausand of years apart: What could the reason for having images of their gods show very similar and sometimes identical "features" ? 5. UFO technology and sightings... Some people love to post videos of secret weapons and UFO's that are simple rocket launches at a perfect time and with perfect weather conditions to attract attention. But what about the things we don't get to see? Just recently the US finally admitted to have a program to investigate what we might call "UFO activity", quite costly one too... This means a lot of leaked videos from fighter planes or spy planes you find on the net are actually the real deal. Often "enhanced" with editing tools but authentic ones have been released by the military and other organisations now too. If it happens over US ground and no US organisations admits to be flying the things we see than what it is? Right, it is a UFO - An Unidentified Flying Object! Does not mean it is alien, despite far too many people thinking an UFO must be alien :( UFO means just that! At the time of seeing it the ones seeing it can not identify the craft or "thing". And, no you are not alone! ;) Happens in all parts of the world and even commercial pilots upload what they can't explain. Oh, you are still a sceptic? Does that mean you think some of these sightings must be alien or do think someone down here uses technology we are not supposed to know of? If you are like me you might like to relax watching the live feed from the ISS. In case you are not try it anyway! Every noticed that that despite the stations own speed "forgeign" objects appear to come towards the station or even to grow in size very quickly? If so you also noticed another very strange thing... No matter what happens up there the stream keeps playing, even at times when the station is moved around a bit to avoid a possible hit with debris. But every single time something appears to move around the ISS or come close to it the feed cuts out. Ok, not every time, for well known stuff orbiting around like satellites, other stations, rocket lauchnes or supply flights they stay on. So, what are those flying objects changing course and direction or even circling the station? Why does the live feed cut out once an object is identified to be unidentified? 6. Roswell technology boom... Some think the US did take ownership of an alien craft, you know the stories and movies I mean... So called eye witness reports and some leaked documents all claim certain unknown technology in great detail. Anything from fibre optics and microchips, over "intelligent metals" to light enhancing glass lenses and seemingly indestructable fibres... Some say that if we would had the option to copy and understand the technology to copy it (without knowing anything about it of course) then the tech boom of the 60' would have been instantly. Imagine flat screen TV's and smartphones with GPS 50 years ago for everyone... ;) 7. Great land in the south - Antartica... The mysteries originating from Antartica range from Atlantis over hidden civilisations and living dinosaurs to the often claimed secret Nazi base with submarines and lost technologies. We all know that life as we know it can't really exists down there, so no strange animals, ancient creatures or a possibility to sustain a secret military base some 60 years ago. Or it there more to it?? Warm lakes containing fresh water with signs of life in them have already been discovered. Same for caves under the ice with temperatures far above freezing - constantly and again with signs of life. Ages ago the continent was still joint with other and in a warmer region so no wonder to find fossils. If we already found places that sustained life for thausands of years then what living things might be down there? Maybe even a place like the Galapagos Islands but for life thought be extinct - imagine Jurassic Park for real under the ice ;) With thriving life, vulcanos, rivers, lakes and all long before the dinosaurs it is not hard to imagine the remains under the ice and carved into the mountains. In todays times it all covered by ice and the sea level is much much higher, so again not hard to imagine that there might be rivers running off under the ice and into the ocean. Some maybe even connected to lakes in a hot spot sustaining life. A secret base from some secret part of the Nazi regime over 60 years ago?? Well, with all we know today about Antartica and is also known about the technological options available at that time it is possible. A submarine could have operated for days or even a few weeks under the ice with support ships available. Not just with so called secret tech but simply with a big sub on a minimum crew and the support of crude ways to reclaim and produce oxygen. If an entrance to a river leading to a suistainable area exists or existed at that time it would have been just a matter of time and endurance to find it. Of course we can't know if it was already found and removed or used since those with capable submarines and technology these days would not talk about it ;) But private or non government explorations map and drill more than ever, so once they hit "restricted areas" or create their own base and research station under the ice we will know ;) What to do if you actually see (or think you do) a real UFO?? Grab the oldest and dirtiest camera aou can find, mount it on the end of your longest fishing pole and create the shakiest video possible. And please make no references at all that would allow to get on the loctation, time or date. Jokes aside there is a good option these days, your modern smartphone, telescope, GoPro or favourite drone. A fake is often uploaded in very bad resolution often so low you might think an old webcam was used. Good fakes are often just a rocket launch, so check for this before you claim it is of unknown origins. Modern tech allows us to record a video in 4K at 60 or even 120FPS , so no excuse for a 320x240 AVI video LOL Optical zoom causes bad results so try to avoid it if possible. Image stabilisation can do wonders for free hand shots of moving objects, so crank it to the max even if the resulting video is a bit smaller in resolution. Geotagging is also a good thing as it allows an easy reference. You might see much more with you eye than what the video show, or in the best case the other way around. That means before you upload take a step back and try too see the video like someone who was not there when it happened! Are the movements reall that impossible? Is it really not just a plane, rocket flares? What sounds did you hear at the time or shortly after that might not be audible in the video? Sometimes a plane in the distance still is in the sunlight while you already stand in the dark - keep elevation in mind ;) Compare with other videos online that claim to be taken around the same time and area - sure you did not film a rocket launch? But if your video is crystal clear and shows the impossible in great detail you might want to check for the usual markings on military aircrafts or flashing lights in green and red. Still all good and impossible to explain? Then what are you waiting for? Tell us where, when and with what type of gear and upload the video so we get evidence of unknown technologies in the use/testing or an actual UFO - Unidentified flying object, until we know better. ;) Again don't take me too serious today but enjoy some of the thoughts and let your imagination wander off a bit. Lost technologies and knowlege exists, existed, is found again - whatever you want to call it. If humans could move stone blocks the size of a small house and create them with an accuracy down to the mm then they might have known more than we think they did. If we could melt granite to form new things, manipulate its sound or carve hollow heads of just a few mm in size then again we lost something well worth knowing. If in ancient times people had no way of seeing really distant and dim stars then how were they able to accurately map them and predict their movement? If milling and lathe technology was known and used when in other parts of the world we were happy to create simple and weak tools: How was it possible to create gears and know about planetary gear systems? If the evidence of the work clearly shows advance technologies used then where are the tools used and why can we find any written records or images of it being used? If even the all mighty US military, secret agencies and space programs fail to explain what they encounter quite often since we fly around: What is really that seems to try to hide from us while appearing to watch how we evolve, explore and fight wars? Since you still bother to read all this nonsense: If it appears we have "evidence" of the existance of beings capable of flying or even space travel since the dawn of time and add all the modern evidence: Is it possible someone or something has been watching us since humans came to be? Did "they" guide some cultures at some stage during their evolution to show us modern ways of creating alloys, machine stuff or understand what was magic or the gods at that time? And if they did help our evolution in some parts then why did this greatly improved society disappear with no more trace than their stone remains? How would we react if they dare to help us again? Is there a reason that even after countless encounters noone tried to shoot one of the UFO's down? I mean, not even a claim for trying since Rosswell..... Not any evidence of a recent landing either..... Or are we just watched so closely because they want something back we too from them??? ;) I blame all spelling mistakes on my annoyingly unresponsive keyboard. But if you still find some then feel free to keep them! I still demand a fee if use them to make money from them ;)

lazer following display help

I was wondering if it is possible to have an icon or marker show on a screen where you are pointing, as a screen displaying a camera feed and an icon to show where it is pointing. My initial idea is to use a laser pointer and an icon to show on the screen where it points by using the colour of the pointer.  I simply wish to see if its possible in one way or another and what methods there are. (not sure I am phrasing it right so apologies if I need to clarify it further) thank you for any information you can you can give me

Zeitgeist, Randomizer, Community Blog, and more!

We just released a bunch of sweet new features and added more cool stuff to the homepage. - Zeitgeist is originally a German expression that means "the spirit of the age", literally translated as "time (Zeit) spirit (Geist)". It describes the intellectual and cultural climate of an era. Our Zeitgeist sorting orders Instructables, Slideshows, and Videos by the most recent comments, so you can see what people are talking about right now! On the homepage, the Zeitgeist section shows featured Instructables with the most recent comments. Zeitgeist is essentially the way we've been sorting forum topics. - You can sort forum topics by "featured" or by total number of replies. Yes, Random fun is still in the lead.- Featured forum topics appear on the homepage forming our Community Blog. We're using the Community Blog to share stuff we find interesting that isn't necessarily related to Instructables. We'll post about local events, new really interesting research, cool websites, and anything else that we find captivating. If you've got something you'd like to share on the Community Blog, write a forum topic and ask us to feature it.- A captcha is now required to send personal messages. This will stop PM spammers dead in their tracks. Yes, Instructables has grown big enough that spammers are trying to PM large numbers of the community - this right of passage for our website makes me shed tears of joy - or something. - Your sorting options will now follow you around while you explore. On the explore page, if you click "recent" to see the latest items and then, for example, click a keyword, to drill down on a subject, or the Slideshow tab, to see Slideshows, that list will still be sorted by recent.- Clicking Randomizer will give your random results within your browsing category. Discover cool Instructables you've never seen before, or resurface old gems!- Finally, we improved the login process: Click the "login" link in the upper right, and you can log in right there on the same page. I'm having a lot of fun with Zeitgeist; let us know what new features you really like, and please report any bugs you find.

Request: How to wire a Firgelli L16P to an arduino

Hi, everybody. If you followed my instructables you know I'm always building robots.  I'm trying to assemble a Stewart platform using Firgelli L16P linear actuators.  My problem is that I can't seem to get the Arduino PWM to talk to the firgelli RC servo interface.  I have... - 12v running to controller pins 1 (-) and 2 (+) - arduino PWM pin 3 to controller pin 3 - controller pin 1 to arduino GND (for common ground) and I'm running a version of the servo sweep example sketch, modified to run on pin 3. The actuator doesn't move. I've tested the control board with the PC control software from Firgelli (works) and I've tested the arduino with a TowerPro SG5010 I had lying around (also works). Notice the controller LED will NOT come on in this configuration, but once I remove the common ground the light turns on. So what am I missing?

Project Help - USB Charger AA batteries

So i wanted to try and pick peoples brains about this and surprisingly my web searches havent really returned anything fruitful on the subject. I have an electronic device that uses 4 AA batteries in series (6v) in a standard arrangement. Due the relative newness of the product and the way the battery compartment is shaped, its basically impossible to replace them with a 6 volt pack and its equally tiresome to use rechargeables as the battery compartment is screwed shut and this is designed to be a portable device. Ideally what I would like to do is remove a section of the case and embed a micro usb socket and setup a charging circuit to the existing battery compartment and stick some long life (lion maybe) AAs in there then just leave the compartment shut and charge via the usb port. Maybe add an led indicator for charge level, i dunno.  However, while i can solder with the best of them, the actual engineering part of laying out the necessary circuit etc is wayyyyy beyond my skills. would anyone be able to assist? Would it be easier to just scrap the battery compartment entirely and stick a battery pack inside the case that was 6v and many many many mah and hook the charge circuit up to that and its leads to the wires going to the compartment and leave it empty? theres plenty of hollow space inside the appliance itself. Second, the device itself doesnt have a "hard off" switch, it has a momentary to boot it up and a reset button. The momentary is constantly being hit in travel and turning the device on, draining the batteries. Theres no internal memory to worry about being wiped, so id love to slap a slider switch on there to kill power to the whole device unless its physically toggled, especially if im cutting a spot for a usb port as well.  Anyone willing to help consult to bring this to fruition? Ill happily give you full credit and buy all parts and what have you, and do all the solder work, just need someone to help me plot out the circuits, decide best course of action, and design a nominal breadboard to slap it together for testing.

Fun and experiments with water - what is your favourite?

We all know that a fight with water bombs or building a water rocket with your kids can be tons of fun. But what about the things that other people might not even know about? A water drop generator for example can produce thausands of volts in electricity! Water can travel up through capilary actions! Water is even used to break massive rocks in cold climates clean and without the need for explosives! Even the simple task of freezing water for ice cubes is now a science of its own for most serious bartenders... One of my old time favourites involving the often weird proerties involved a very small BW TV and a fishtank. After a lot of cleaning and rinsing I placed a TV into a spare fish tank filled with destilled water. Some other tiny tanks were filled for comparison with tap water and other household liquids. Switching a LED on by placing some electrodes in water without a battery was easy to explain as a battery was just created. Showing that copper can tavel from a wire onto a coin was fun too. But most people got really stunned seeing a movie or the new play on a TV under water - after all we just learned water and electricity is a big no no... What is your biggest "trick" or experiment involving water that noone knows about?? I am working on ultrasonic HF/HV experiements trying to figure out why it seems that under certain conditions the water "produces" more energy in the form of gas, steam and light than what is put into the system from the electrical side of things. Once I can replicate some experiments and understand them I will post my results, so give a few decades please ;)

WTF is going on here??

(Gave up yesterday, so the news are a few hours old...) For a few hours now I really struggle to leave a reply, create a new topic or simply navigate the site. The robot invites me to a game, which might be fun at other times but not when you think you might want to leave a reply to a topic. I understand that updates and changes need servers to be offline for a while and also that some tasks might cause a bad response at those times. What I don't understand however is why noone bothers to consider to make an announcement about works to affect the site for more than let's say 30 minutes. Even if it is night time or some other time where everyone in the states is asleep: Instructables is well used and visited from other timezones around the globe.... If I update the forum sections, or recent answers (or any part of Instructables for that matter) I should see a popup that notifies about server works or other disruptions so I won't bother trying to post something in that time which in many cases will mean I loose what I just typed. Or better still: Send an Email to all members and inform them about planned or sheduled works. Can't be too hard to do can it? As said, the robot is nice but will only show once it is too late ;)

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?

Hello, I have a few questions.

Hello, I've been frequenting this site for a number of years now, but have never actually posted anything. However, I am now starting up an important project, that may be little much for me, and I'm wanting to make sure I have a full understanding of the resources I'm going to need to complete the project. So I'm going to give a little background in the hopes of explaining why this project is so important. I'm a college student looking to get my associates in Application Development. I'm currently in my second quarter of classes, and am beginning the planning process for what the school is calling the "Capstone Project" (aka Senior Project). So as it stands I have about two years to, assuming everything goes well, to create a new application, and I decided I'd be a bit of an over achiever (with this project even if I'm not with others xP) and develop an AI assistant home robot based off the Japanese Gatebox ( I choose this because I feel it's something that really challenges all my skills, as I started my career off as an IT in the Navy specializing in System Administration, then worked as an on call computer repairmen for a year after I got out, and am now working on becoming a programmer. Now while I've done some research into, and am forming a plan for the software side, there are a few things on the physical tech side that I'm having trouble with. First, I would like to use a prism hologram, rather than a projector and clear screen, however I'm also not wanting the base to take up a large area on a desk. So I was wondering if there were any cheap projectors that could work, or if someone knows of a small screen that could allow for a somewhat tall projection? Second, as a kind of way to make my system stand out as it's own thing, I was wanting figure out a way to wirelessly (preferably over a wifi connection) to stream the image from the "Central" unit to a "Remote" unit somewhere else in the house, while on a budget. I know Wireless HDMI systems exists, however given there price I would prefer to find an alternative method. Any and all help would be appreciated.

Heat storage device for car cabin heater

I want to increase the heat storage capacity of the existing car heater so that I can run the heater (just the fan and a liquid pump) while the engine is off and so I can have a warm car as soon as I start on a cold day. The current heat storage is the coolant circulating in the engine. I want to increase the capacity of that. Instead of simply attaching a liquid reservoir to the heater circuit (to increase the coolant volume), I was considering using a picnic cooler (insulated) box with a coper tube coiled in it. The box would be filled with oil and paraffin. Paraffin melts ≈ 40° C  and I can take advantage of the latent heat of fusion when the paraffin changes phase. The oil is a medium to suspend the paraffin. I need a recommendation of an electric 12 volt pump to circulate the fluid. I request any other thoughts or criticisms.

individually addressable led DECORA switch

Greetings collective Instructables genius, Here's the deal, I have a kitchen,  I also have several strips of individually addressable LED's powered by the same supply.  I like the led's, I really the fade between teal and blue as it gives the impression that you're underwater.  At any rate, having anything other than a decora sized switch is out of the question.  I don't need another remote, or some box with switches on it to control the LEDs.  I'd really like a switch that can be mounted in a single gang electrical box, that can be covered by a decora faceplate.  I have a media cabinet where the power supply for the LED's is housed, and the switch can run to the supply in the cabinet.  I need at least 4 programs (like the underwater effect), though 8 would be ideal.  Any thoughts on how to approach this?  I'd spend upwards of $80 for a finished product.   Any input is appreciated.  Thank you Eric

Color Conversion

So, I was recently playing my 3ds, when I figured out that the firmware I downloaded, "Luma", can take screenshots. However, there is one problem. The program which takes the screenshots assumes that the 3ds is using 22 bit colors, when it is actually using 16 bit colors So, the image's colors are quite distorted. This is a problem. However, this shouldn't be impossible to fix, right? If I'm correct, we should be able to do the correct conversion as long as it was saved in a lossless format. Are there any programs which do this?

Recent answers not updating properly

Not sure if it is bug but IMHO it qualifies: When I update the forum section I see that the number of replies changed if they did. But in the Recent Answers setion nothing happens. Even after several hours I don't see the number of replies changing, despite quite often already showing a few when checking a question. Apart from that the number count in both the forum sections and the ansers sections seems to be confusing to me. In some case replies to a reply are counted in other case not. The numbers don't really matter but knowing if someone left a reply to somthing would be nice. But with neither the counter nor the position in the list changing it is next to impossible to find out. On a side note as I already asked many times: Can we ever expect to see an option to sort replies by the time and date they were made? Might be just me but scrolling through a big topic after getting an email that someone replies often results in nothing at all. I see replies from several years ago on the top then some that are a few months old followed by newer or older ones. There is no order of any kind that I can see! So please, if any of the great code monkey reads this: Can you explain the logic behind the missing order? Can you explain why exactly it seems to impossible to sort replies in a way that makes reading and understanding what was replied possible? Can we expect to see a fix or selection buttons for the order in the new year?

Making a better spot welder....

I am in the process of building a proper spot welder from scratch. Proper more in terms of the electrical and electronics part but not so much in looks ;) My problem now is to find useful info on what power levels are required for certain tasks. I realise that welding thin sheet metal won't need as much time and amps as welding a 3mm stainless steel rod - but what is a "good" power level? I watched a bunch of Youtube videos showing various approaches but for many it seems the producer had no clue about the difference between creating a short with burn marks and a weld... Especially when it comes to creating battery packs with a capacitor bank as the main power provider you can clearly see the device burns holes but does not really create a welded spot. On the other hand there are a few videos showing spot welder made from a MOT that seem to produce a proper melted and welded connection. When I used a proper spot welder at work it had timing settings, power levels and even a feature to adjust how the current rises.... Not to mention a gauge that checks the pressure and only activates the welder once the set point is reached... There is a ton of info out there that after a thausand words still tells you nothing you need to know :( So is there anyone here who can shed some light on the actual process of spot welding in easy words for everyone to follow? I am aiming for a max output of around 400A @ 1.5 -2.5V with an adjustable shunt in the transformer core to avoid oversaturating the core. In a later stage I will add power control over the primary side but until then it is only time control, from a few ms to a max of 5sec if the damn controller arrives one day. Big questions: 1. Is a power control really required or is it possible to cater from thin to thick just by using different timing settings? 2. Since a MOT is used for the power supply: Is it better to leave the shunts out to fully avoid saturation by adding an inductor in line with the primary or is it still better to adjust the shunts under load to get the maximum power possible? 3. Aluminium and other materials benefit from using AC but would be good to have a DC output too, if so then what materials really need DC? 4. All I could find is that copper is used for the electrodes, due to resistance and heat transfer - are there other options apart from using copper? 5. Tricky one: I would prefer to use the secondary winding as the new primary to avoid core saturation and to lower the load on the power outlet. Where can I find very thin copper bar material that I can coil up and insulate as I would quite a few more turns to get at least 1.5V out of it? Just don't like the idea of spending days rolling a copper bar thin enough.... For the advanced model at a much later stage: Of course I would like to be able to use a proper power control instead of a motor dimmer or similar. For obvious reasons an inverter microwave jumps to mind. But after checking one I noticed one big problem: there are not really that many windings on the primary of the transformer at all! Same way our modern switchmode power supplies only use a few turns these things do exactly the same. After some quick and dirty initial tests I realised that even a single turn of thick wire already results in over 20V on the secondary. Wasted a lot of wire and time making one coil with 5 turns less and one with 10 turns less but the system would not even start with it. Seems these things need a fixed inductivity on the primary that matches the frequency used, in my case 36kHz. Would love to overcome this problem so I can at least go down to a single turn to get under 5V on the output side as space is non existing on these inverters. Can I cheat? Do I need to change the circuit to match the new primary coil? Am I thinking in the wrong direction altogether here? And added bonus would be to be able to adjust the power from around 15% to 100%, so far the electronics don't allow anything below 45%. Is it possible to drive these inverters in resonance? (Ok, off topic as I would like to use this for a beefy HV supply) Last thoughts: I know people already used Arduinos and Raspberries with displays and all but so far I have not found anything that shows how to do it properly. Seems all that counts is to create connection one way or the other and to call it a spot weld even if it is just a burn hole from discharging a capacitor bank through a needle like electrode.... For obvious reasons I don't want to create just another spot welder that makes a professional pee himself laughing about it. IMHO nothing beats personal experience with something but I don't really like wasting my time by trying what other people alread did a long time ago. So if YOU already built a MOT based spot welder and used for more than a few spots I would love to hear from you! Let me know what type you used, what problems or shortcomings you noticed or where you feel it just does not work out the way you expected it. From simple things like always getting bad sparks or arcing, over how easy or hard it is to get consistand results to whatever really annoys you while using your homemade spot welder. I hope that your feedback here will help me to write an Instructable on building a spot welder that does what you expect it to do, not once or twice, but everytime you use it. Mechanics might vary the same way the electrode style does but the weld should always be a proper weld that won't tear apart ;)

Pet Travel Kennel Into Doghouse

Hello everyone!  Finally made an account after using this site for over 5yrs because I'm hoping to find some advice. I have a big, plastic, dog-sized travel kennel (airplane kind).  Since my pet isn't using it anymore, thought I'd convert it into an outside doghouse seeing as though it's practically complete already.  To prevent rain from getting inside, I need to cover up the side & back barred "windows".  My 1st impulse was to replace the metal bars with wood, but rain would just leak in through the top.  Any thoughts on attaching a makeshift roof?  I've added a picture of it to help (the metal door has been removed).

Two-way hinges

My wife and I bought an 80s designed house that's not that well designed. We keep one of the litter boxes for our cats in the garage, which is accessed from the inside through the laundry room; and we want to install cat doors so our aging felines can pass through the doors easily to get to it, while keeping the draft from the garage out of the family room. The interior door (between family and laundry rooms) is a standard hollow core and the exterior door (between laundry and garage) is fire code rated solid wood door.  We tried a standard top-hinged door with the cats already, at our old apartment, and the cats didn't take to it, so we we're hoping to do french doors, since they know how to get through normal doors pretty well. But we're kinda stuck on our lack of knowledge about hinge designs; we need hinges that swing both ways. Has anyone out there successfully completed such a design/installation and would be willing to share pics and secrets?
