Perpetual Motion

If perpetual motion is theoretically impossible, how is the earth still in orbit? Or how is anything in orbit? There falling at the rate at which the object there falling towards is rotating and they'll never stop rotating or falling so isn't that perpetual motion?

Webcam Motion Capture.

I came across a youtube video recently where they use 4 webcams and motion capture software to do a cheap diy version of motion capture. Info seems pretty limited here and I can definitely use it for my indie film.  Please let me know if you've used such a set up and what software you used

Motion Triggered Horns

I'm starting this one over, I made a mess of the last topic. Essentially what I'm starting with is a driveway wireless alert system (http://imgur.com/a/RgDeG)  and a car horn. The car horn is wired to a push button switch. (http://imgur.com/lg7Gbvj) What I'm trying to do is replace the [S] (switch) with this wireless trigger. The alarm speaker outputs at a very low voltage, ~0.08v: https://vimeo.com/75827101 The alarm LED's output 1.75v (measured from + on the one LED and - on the other, there are three total, in series) What would be the best place to tap in to get voltage from to trigger the relay? I think from the previous post I'll need a transistor switch of some sort? This is the part I need help with. Usage: Tractor pulling hayrack riders over a bridge, I'll place the sensors ahead of the horns so by the time the tractor is at the sensor the hayrack is right at the horns. Hope I posted in the right spot. Thanks

Motion detection sprinkler

So my neighbours cat uses my garden - my vegetable patches to be exact - as a toilet. I know there are many many people out there just like me who are sick of it. I happen to like cats, used to have one myself, but i dont like them crapping in my garden. I've tried everything. Nothing works. But they dont like water and having soaked the cat at 4am with the hose a month ago i got a few weeks of bliss being left alone, until just last night when it decided to try again. I can't wait up for it all the time. So I want to make a motion detection sprinkler. Cheap as I can. I could buy one ready made like the Contech ScareCrow but it's £50. I figure it can't be that hard, I have several hozelock sprinklers in the garage that I dont use. If I could buy a cheap infrared motion detector and some kind of actuator? Maybe I could rig it up to the hose and sprinkler, but not sure exactly how to do this. Hoping someone here can suggest how to proceed?

random motion gearbox

I have been exploring wast of creating a random motion from a gearbox, i need this for a segment of a kinetic work i have been doing for some time now. random motion seems somewhat difficult to achieve so i came to the conclusion of using magnets! the gearbox i am working on at the moment works by orbiting one magnet around the other, the central magnet spins the output shaft while the orbiting magnet performs many rotations around the central magnet tugging it to different positions giving an almost random movement (patterns can be found). i was wondering if there were other maybe more effective methods of achieving random patterns of movement without the use of electronics.

Motion Detecting script CHDK help?

Besides this, I don't understand the function of the two settings to change the script they give you. I would be grateful if someone could help me on how to use it. I'd like a way to do it without any programming on a computer or something, a way to do it on the camera itself please. Thx in advance super_me

Perpetual motion & free energy is it possible? Answered

Hi Eric/Instructables, Basically I have been looking at perpetual motion and am led to believe that it is impossible due to the laws of thermodynamics meaning heat/energy has to be transferred somewhere, so I came up with a few designs which may challenge this theory.  Without wanting to reveal my designs and ideas too much I will explain what I am trying to accomplish and would love your opinion as to whether you think they are viable. I have 2 ideas, one is to use 'rare' magnets (which aren't rare at all so cost and obtaining them is not as hard as it sounds!) and have the magnets propelling round like a wind turbine design using the opposite poles effect to repel the magnets and get the turbine started.  Once the turbine is in motion I will harness the electricity created by the movement of the turbine/motor in a capacitor or kinetic store. This stored  electricity  can be used to keep the magnets magnetized by wrapping wire coils round the magnets and passing the stored current through the coil to keep the magnets repelling each other and spinning the turbine. Idea number 2 is a similar concept just dropping the use of magnets and using the method of so called free energy where you can get a small voltage from using a radio antenna, capacitors and germanium diodes (there are several example videos on the internet) again using a wind turbine effect to keep re-fueling the capacitors so the voltage drop when the load is applied is nulified. Perpetual motion is the dream and I think the transfer of heat/energy caused by friction can be harnessed and put back into the workings of the appliance/design, Many thanks for your time in reading this and hope for any replies positive or negative the dream will live on in my head and heart  :)  Mark Smith

Is there really a theory behind the hojo motor scam? Answered

I ran into it on line.  More truthfully, it ran into me.  I've never heard of it.  I do know it's a scam, you can't spend $100.00 at the hardware store and build a device that supplies 120 volts at 2oo amps to power a house.  The whole thing did pique my curiosity, just like a gasifier or hovercraft or flying lawnmower would.  The problem is that if you try to find just information on what the thing is all you get is page after page after page of scam sites or people trying to sell plans for some mythical device. The only thing I've been able to ferret out is that it's some kind of perpetual motion device that will power my whole neighborhood if I spend 9 hours building it.  I like to think none of my fellow humans are silly enough to believe that. Anyway, without trying to tell me you have one powering your house and an orphanage out of kindness or trying to sell me plans please explain the theory behind it.  Sorry if I sound grumpy, I've been battling scam sites trying to look legitimate for the last hour.

Stop motion camera crane

Ok. I need to create a camera crane. It dosn't have to be very big since I'm using it for stop motion. Just a simple pan and tilt crane with a counterweight to off-set the camera. Now, I can make a regular one very simply using a video crane method that you can find on this site. However, this crane must do 2 things. 1. It must be able to move at incredibly small increments. Only fractions of an inch at a time. 2. The crane must be able to hold it's position in a very sturdy manner. It cannot move even in the slightest because stop-motion requires that the camera does not move at all while individual pictures are being taken. For the life of me, I can't figure it out. Traditionally, a "step motor" is used to create the individual movements for things like this. But they are incredibly expensive. I've had more luck with gears and servos, however I want to figure out the logistics before I just go buy gears individually on a website that may or may not work. Your help would be appreciated. Thank you.

Motion Detector Trail Camera

Motion Detector Trail Camera motion, detector, detection, surveillance, security, trail, camera, webcam, webcamera, wildlife, IR, arduino, cheap, inexpensive, spy, cam Hello everyone. I'm planning on building a motion detector triggered "trail" camera, as inexpensively as possible.  I want to use a cheap IC (integrated circuit), if possible, not a $45 Arduino.  I've learned that the most expensive component of this project seems like it will in all likelihood be the digital camera module (the lens and CCD, which is a pixelated digital sensor for the brightness and color of light).  However, I have an old webcam from which I could salvage the camera module out of, if reasonably convenient.  And this is the primary thing I think I'll need help with. Beyond that, my plan is to get a cheap IC, plug the camera module into it on a breadboard, find (hopefully find and not have to delve into learning how to program this) some programming code for the IC to capture the image data and turn into some kind of conventional image file, and then capture the digital camera files on an SD card via SD card shield plugged into the IC via the breadboard.  After the initial project is finished, I'm thinking of taking it a step further by transferring the image files directly to a computer, and upload them immediately to the web but that will come later. And of course write some code to signal the camera to shoot when the motion detector detects motion.  And do some research about which kind of motion detector I want and get it.  But this part seems relatively pretty easy.  Oh, and also get some kind of battery; probably a Li-Ion cellphone type battery with a shield or 'holder' for it.  Haven't yet researched about the shield / 'holder' part for that, but seems like it should be easy. Questions: 1) What kind of programming would I need for the IC to capture the image data from camera and turn it into conventional image file?  Where would I get it?  ...or what?  I just want pictures, not video. 2) How do I salvage the 'camera module' from a web camera for this?  Or rather, perhaps I should ask, once I salvage it, how exactly do I plug it into the IC to send the image data to the IC...? 3) What is a cheap but effective IC for this? Anyways, thank you; cheers. Jack Oh, also wanted to note that I indeed have been looking through many tutorials about this stuff.  I guess I'm at that point where I feel like it would be worth it to write down where I'm at and ask for further directions.  Lol.  Thanks again.
