The power of C.A.D.

This is what happens when I get my hands on C.A.D!!!! And this is a pic of the RC plane I am in the works of designing. I dont have the ratios to make everything the proper size so I had to estimate. I plan on having it done by the end of my school year in September.

What kind of plastic film is this?

Hi All, I've come across this art installation by Ann Veronica Janssens https://imgur.com/a/RhWVa and would really like to find out what this semi reflective material is for a small project I'm working on. Does anyone have any idea what it may be and where would be a good place to source something like it? Thanks

need help coding Arduino to drive two 12V DC brushed motors

Hi – I need the coding for an Arduino Mega to (separately) spin two 12V DC brushed motors through a pair of MOSFETs to about 2,000rpm. I’ll be using  Hall effect sensors and magnets mounted on the motor couplings to provide actual speed feedback. Please help or point me in the right direction?? Many thanks marcelbaur

A question about an instructable to do with clocks I saw a while back.

So if you go up to the search bar and type in the word 'clock', you get all sorts of results. Small clocks, big clocks, plastic clocks, metal clocks, Batman clocks, Skyrim clocks, everything under the sun. Bar one. The thing is, all these clocks are generic. They all are mostly the same. A standard circle with hands and the hands marching round the clock in circles. I'm not saying that this is bad, I'm just saying that seeing the same thing over and over and over gets very boring for me. So when I saw a clock that was unique and different, it was like a dream come true. However, if I try to look for that particular clock again, I can't seem to find it. The clock in question acts similar to the linear clock, but is still circular (hypocrite). Looks sort of like this:                  | ________\|/________ |________________|      |___________|         |________| The top row shows the seconds, the second row the minutes and the last the hours. Essentially, the hours and minutes and seconds all turn while the actual base stays still. The numbers are along the rows and as they turn, the arrow points to what the time is. If anyone can find this instructable, I will be grateful. Otherwise, I will be forced to do this project without the help of any sort of instruction.

Timed control board for a reversible motor

Hello, In need to connect a control board to a reversible motor so that the motor would rotate in one direction for "x" seconds and then automatically switch and rotate for "y" seconds in a reverse direction. I got the following parts in hand: - reversible motor - https://www.amazon.com/gp/product/B01N687NGU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc;=1 - control board - https://www.amazon.com/gp/product/B01HB1X75U/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc;=1 - DC adapter - https://www.amazon.com/gp/product/B00S1GRFYY/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc;=1 Control board works and is going through the proper cycle as indicated in description however the motor only rotates in one direction and never switches. Realizing this this something that I am doing wrong with wiring, so hoping for an advice from someone who knows better in terms of how to set it up correctly and which jumpers or anything need to present so that it works and where things should be wired into. I am also attaching an image with descriptions for connectors that I received from the company. Thank you in advance for your advice.

Medium weight quilting Fabric

Hello Everyone, I'm new to this type of project but I was looking to make a knife roll for a friend who will be starting culinary school soon. The one she bought for school is kind of dumpy and while it does the job we had found some great looking roll up ones online they were just kind of expensive. So i figured I could make her one for half the cost. It all seems doable. The wall I'm running into is the majority of my sewing experience has been stitching hems for Halloween costumes so my familiarity with fabric types is minimal at best. I wanted to make her a roll out of a fabric with a print on it and and finally finding the right one, at a good price point, I find myself worried the quality of the fabric may not be what I'm looking for. Basically what I found was described as "medium-weight quilting fabric 100% cotton" another one was called "broadcloth." I, however, have no idea what they are. The majority of no leather knife rolls we did find were made of canvas so I was hoping to make one of similar durability. To sum it all up I'm just wondering if this "medium-weight quilting fabric" is anything like twill, canvas, linen or musslin. I feel like those fabrics, especially the first two, would be quite durable for some like a chefs knife problem is the pattern I'm looking for isn't on those types of fabrics. Any and all help is greatly appreciated. Thank you in advance!

3V Hobby Motor in a 6V Circuit.

Hi. Hope I'm posting appropriately. If not, please forgive an older guy! I'm working on a Useless Box project that I power from a 6V wall wart. I've already completed one and it works great. I use two standard servos with an Uno. But now, rather than being satisfied, I'd like to add a 3V hobby motor, which naturally would only run randomly for short periods of time. I have purchased an AMS1117 step down module which is rated at 800mA from Amazon to get the correct voltage for my little motor. My question is, do I need to add a capacitor across the leads or to the casing. If so, how do I determine what size? And while I'm asking, is there anything else I need to think about? I appreciate any help as this is a new hobby for me.

have i got 1 good driver or 3 bad ones

Hi all, nice to be here I have just finished building my first cnc router and about to start actually doing something with it, during my build I somehow managed to blow up 2 grbl boards and 6 drivers, hey note to myself, don't connect voltages when tired late at night also I have a problem, I think, thanks to YouTube I found how to set the voltage using the trimmer pots on the driver boards, I set all 4 drivers initially to 0.75 volt and it all works and tests fine, apart from having to buy 2 more driver boards when the trim pots fell off that is apart from one of the stepper drivers powers one motor (Y axis) and when it finishes working it goes absolutely solid locked up and sounds like it is groaning, the other 3 are firm but not locked up I tried increasing the voltage on the 3 looser stepper motors to 1.0 volt and it didn't seem to make a lot of difference, but to get the solid stepper driver down to the same stiffness I have had to drop the voltage down to 0.4 volt and it did stop groaning and loosened a bit I swapped over the motors, same result, moved the driver to another spot on the grbl board exactly the same effect on a different motor, so it looks to me like it is the DRV8825 driver board is this a case of I have 1 bad board and 3 good boards? or 1 good board and 3 bad boards ? any help would be more than welcome info on my cnc build and components below basically the cnc has a bed of 900mm x 900mm and is pure self build made up of parts found laying around my workshop, rails bearings lead screws etc, and I added in a new Arduino uno (of which I am novice) and a new GRBL board and ended up using DRV8825 drivers, stepper motors are used (eBay) 4 x identical minebea 23LM-C343-14V wired from 6 wire down to 4 wire with pairs being red & yellow and pair 2 being blue & orange, which I believe is correct LINK TO STEPPER MOTOR SPEC SHEET please correct me if I have made a mistake I have used links to set all drivers to 1/32 micro stepping, also set the mm rate so it is exact at 500mm travel, and set max speed at a sensible 400mm per minute as I am not really expecting supersonic speed and all is nice and quiet, nothing straining I have paired 2 of the stepper motors via the grbl to drive the X axis and used the clone spare on the GRBL to make that work, which it does marvellous The CNC structure does need strengthening up as mostly built on ply at the moment, but everything works as expected, the spindle is a nice almost new RotaZip high speed tool that I bought new about 4 years ago and only used it on one job so keeping stuff does come in handy even if wifey says it doesn't Look forward to sharing info on here as I learn more

Arduino/ESP8266/servo noise when idle

Hello everyone My project involves a robot with LEDs, servos and an Arduino with a Sparkfun ESP8266 shield on top. Everything else works fine, I send web requests to the robot and LEDs are blinking or the servos are moving. The problem is that when idle I have noise on the servo. I have tried  1. Pull-up and pull-down resistors 2. Providing external power to the servos 3. Putting an aluminium foil between Arduino and the shield and the problem persists Commenting out parts of my code I isolated that the noise appeared upon uncommenting this part of my code void serverDemo(){ ESP8266Client client = server.available(500); } but I cannot understand why.  Could you please propose me any idea?

Can an Instructables Member Make Classes?

Hello, I'm part of a company that does a lot of stuff that customers would ask questions about, and I was wondering if it is an option to make classes on Instructables or if that was a potential consideration from your end. I would find it useful, even if it was limited to a Pro membership. It's something that I think personally my company would consider paying for. I would even consider it individually. The ability to make classes that people would want to learn would be invaluable. Of course the only question would be is if others feel the same way I do. If this is already a feature that I can take part in, let me know, as I'm not currently aware of any way to access it, and I don't want to pay for a Pro membership unless I know for certain that that's a feature that would come with it. I would appreciate any answers you can give on this topic. Thank you, and hope you're all having a pleasant day. -DJBarnett

product advertisements disguised as instructables

I have come across a number of  instructables by people or groups selling a product or pushing for support for a particular product under development. Fair game, if they try to help to do something, but instead they preface their "problem solution" with the need to buy such and such piece of equipment. I have no problem with this approach, but sure wish such instructables  would be identified as "promotional instructables."  or at least be identified  at the beginning of the instructable as showing how this specific product is the answer to an identified intractable problem.

Homemade player piano

So I got two pianos for free, one in great condidtion other than being out of tune and having a stiff action, and the other, a player, having a badly cracked soundboard and pinblock.  I salvaged the player pneumatics and bellows from the player and managed to mount it upon the other piano.  On each note bellows there were rods that pushed on levers to trip the action of the player piano.  On this one, these levers are about a foot and a half above the bottom of the action, because it is a console piano (shorter).  I've tried linking the bellows to the keys with hooks (which didn't work, it just pulled the keys off the center pivot point) and directly to the action, on the bridle strap hook.  I've tried different strings and two different gauges of wire, but they always seems to stretch, untie or to come unhooked whenever a note is triggered with the player, or with the keys.  If anyone has ideas on how to link the player mechanism to the piano action, any help would be appreciated. Thanks!

All right, let's clear this up: What the hell is inside of a battery?

Really frustrating: I accidentally closed the tab I had been working on for about 15 minutes, so I'll probably be missing a couple of questions I had been meaning to ask.So anyway: When I peel off the outermost metal covering of a zinc-carbon battery, I'm just taking away a protective steel covering, right? When I get rid of that, am I looking at the actual zinc "case?"What is the sticky, black material that surrounds the graphite rod? Is that manganese dioxide? Is manganese dioxide the same thing manganese oxide?Further outwards from the center of the battery, there is another black substance. Is this ammonium chloride?I haven't actually chopped open a carbon-zinc battery all the way yet. Is there a good technique for removing all of the contents?How can I tell the difference between the two black substances? Is the moist, black paste ammonium chloride? If this is so, then why, when I pull the graphite rod out of the battery, is it sometimes coated with a sticky, black substance? Do the substances mix with each other or are both substances sticky and black? Is one a powder?Is it okay to drill through one end of the battery? If I drill into the negative terminal of the battery, what will fall out?Basically, what are the physical properties of all the materials? How can I tell the difference between them?Now: On to alkaline batteries...Both types (carbon-zinc and alkaline) appear to use manganese dioxide. Is this so? On Wikipedia's article on alkaline batteries, manganese dioxide is described as Zn/MnO2, with the two as a sub-script. Does the slash mark mean that zinc and manganese dioxide are interchangeable?What will I find if I open up an alkaline battery? Is it safe to do so? What is a good, safe way to open one up?Are there any particular "fun" applications for these chemicals? Think explodiness ; )I've heard that manganese dioxide can be used to produce oxygen. How do I do this?There might be some yellow tag-box notes on these, pictures. For the context, visit my Instructable on how to make your own carbon arc light. I'm not trying to advertise, I'm just anticipating someone asking about them.

IR TV Remote Codes

With all the projects on the net with the raspberry pi, I cant seem to find the one I am looking for... I want to be able to point any tv remote control to a sensor on the pi, and get the IR code on the display. This way I can use that code to program any button I want on a universal remote control. for example, if I point my dvd remote to the pi and push the play button, the display would read 4753. Then I would use this code to program my universal control's play button. I know I have seen this project before, just don't remember where. Any Help?

Bluetooth finger print reader

I need a design (better yet an operating) hand held, battery operated bluetooth enabled finger print reader. That is, the bluetooth enabled finger print reader would store one finger print and then compare the person usign the reader to the print stored. If the prints matched it woudl send out an approval code. I am sure someone out there could make one. How can I contact that person?

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
