Has anyone ever made a motion lamp. I thing the rising heat from the bulb or candle made the inside rotate giving the illusion of 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?

I have a project for school where i have to create a motion sensor toilet tissue dispenser kind of like a tiny paper towel dispenser i could put on a counter. I dont know anything about how motion sensors work or how i would make it work. I just need to figure out the price it would be to set up the motion sensors, gears and everything. Any help, such as links to parts or anything that would give me a better understanding of how to set up motion sensors and connecting them to gears and such, would be appreciated.

I would like to build (from easily available materials) an outside motion detector that would alarm if anyone came into my carport at night. Battery powered (do not want to have to do house wiring), motion or ir sensitive (whichever gives range), sits somewhere outside in carport and when activated broadcasts signal to turn on buzzer or other warning device in house bedroom, 100 ft or so away from detector. I do have an available electrical plug in the carport so I could use that for power instead of batteries if needs be. Does this stimulate anyone's creative juices? Thanks

Hi, I'm looking for a motion detector with difference & wonder if anyone has any bright ideas. I have setup a bird box on the side of my house & it's early spring here in the uk. I'm only getting occasional visits from a bluetit couple & would like to know when the're home.An initial idea is to check the brightness of the video image. It's monochrome so the brightness reduces dramatically if a bird is home. Any ideas how I can acheive this?bird box link

My wife just bought a tin pig that is about two feet tall and she wants me to see if i can make it squeal when someone walks up to our front door. i figure it sounds like an easy project but i am not sure. i have enough experience wiring, soldering, and general tech stuff. i have read up and can guess that i will need a pair sensor and some sort of micro controller, but i am unclear what or what to do with it. the goal is to have a piece that i can put inside the pig and have it detect a visitor and then trigger a sample of a pig sound. i know its silly, but i do what the wife asks!! ideas of maybe a link to something specific would be helpful!

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

So...If I buy an IR Emitter LED and an IR Receiver LED ...and put them face to face...and get power to each of them....Can I somehow create a motion sensor out of that? For example, if someone walked between the 2 LEDs, it would trigger lights to go on. Is that possible?

My roommates and I decided that we wanted an electronic project to work on and we chose to try out making a motion detector. The only thing is, we really have no idea how.We have this PIR sensor, a small PC board, some wire, a buzzer and soldering equipment.My question is, how can we make a motion detector that buzzes when it senses motion? What more do we need to buy?We have looked online but couldn't find anything for people that really have no idea what to do.Thanks for any help!

Hi. I wanted to make a device that would play a piece of audio that I recorded when I trigger some sort of motion sensor. I don't know what parts I would actually need as far as a motion sensor, a record/playback device, or other misc parts. I have a fair understanding of resistors and voltage but I'm pretty much a beginner. If anyone could point me in the right direction, that would be well appreciated.

Hi I was wondering if anyone could tell me how to build a motion sensor that activates a recording. It would have to be a small unit no more than 3-5 inches. what I would like to build is that when a pereson walks by the unit they activate the sensor and a recording(that has been pre recorded) is played. Any ideas on how to do this??????

Hello forumites: Needing some assistance in identifying a motion sensory component. Wife bought this annoying bird ornament at the dollar store the other day and the packaging stated it was motion activated. Sensitive apparently because the thing almost never shuts up. Had an idea to get a few more of them and pillage for parts to make a motion activated night light for my youngins when they get up in the middle of the night. Funny thing is though, it doesnt look like any motion sensor Ive seen. Perhaps someone out here can throw me a bone.

Hi guys + gals, i got burning question in my back. Does anybody have any idea how to make a really simple motion sensor? ex: I've been wanting to make something,kinda like an simple installation. It's gonna be a small fishes, so everytime somebody passed my fishes, the eyes of the fish gonna follow the movement of that person. Any help would be deeply appreciated. thank you before hand for the ideas and suggestions.

Hello, I am an artist and want to do a sound installation. Basically I want a movement sensor that activates sounds. There will be about 15 different sounds and each time someone passes by the movement sensor will activate a different track. Can you help me with that?!?!? I need to know how can it be done!!! Thank you Fernanda

You know those liquid motion toys you often find at places like Spencer gifts in which a denser liquid (usual bright colored) drips down onto a spiral and you can watch this discrete bubble ride on down? I'm wondering what's inside them and if its feasible to make your own. I've heard lots of things, that the clear liquid is usual a light oil and the colored part is water. I've heard the reverse, I've also heard that there is no water in these things that both are different oils.any help would be appreciated. if your still wondering what im talking about heres a place that sells them : http://www.officeplayground.com/spiraltimer.html

Hi I'm trying to work out what I would need in terms of components and possibley wiring to produce a circuit of which will allow a motor to start for a short period of time once a motion sensor has been triggered then turn off automatically. It is basically to track whether or not something has exited a large box rather than its entry, this is so that on exit of the box the motor will change the the internal environment but not be triggered by entry, only on an additional exit. I am confortable with the mechanical side of this project however I am a novice to electronics and any help you could offer on the subject would be fantastic. If you need more information please feel free to ask. I could insert a quick sketch if this would help.

I want to cover a stairway. The motion detection camera that is in the library here is a very good start. I want to add the following functions. 1. long battery life 30 days min. 2.. Rotating photo storage. i.e. when the memory is filled up, the camera will overwrite the oldest photo. 3. Date and time stamp A unit like this could be left in place for a long period and only accessed if something has happened that need to be checked.

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

I would like to know how to combine narrow width motion detector to control LED Say putting two sensors side by side and each controlling independent LEDs. Not sure how to go about it. Is there kits available that I can modify? Also, I thought about using IR but I dont want to break a beam rather I hope make something thats like any outdoor motion sensor light but in a small scale that can control each LEDs. Any leads? I got almost zero experience in electronics. Well, if you count elementary school elec class that I took but forgot everything about it. thank you

I've searched for weeks for an answer that doesn't require a PhD in electrical engineering and hope someone here can help. I have a motion activated Halloween prop (walk by and it talks, etc) however, it requires quite a bit of light in order to detect the motion. I'd like to either put it on a timer and/or just let it chatter randomly so that it will actually be useful. I love the phrases he uses more than the prop itself and plan to remove it's electronics to place in a different prop. However, it's pointless if it remains quiet as we won't have him close enough to a bright light source to make him talk. Help? Thanks Elaine

Hello, I am currently developing a wireless PIR motion sensor for my home with Arduino and I need some advices (I am new with Arduino). The product will send a signal everytime it detects someone but I need to switch on/off when I am at home. For instance, before switch on/off on the device, it will detect a movement (and I don't want to). Is there any way to switch on/off remotely (right before entering in the house for instance) ? 1/ Infrared ? Is it consume a lot of battery ? 2/ Bluethooth ? Is it consume a lot of battery ? 3/ Other ? Thanks for your help,

I've searched these forums and found some similar threads but nothing specifically like what I'm trying to do. First, I am NOT very DIY savvy. I'm a computer tech and can build a PC from components, but I'm not a drilling, wiring, woodworking type. What I'm trying to make is a small remote motion-sensitive light so that when the motion sensor trips, a small under-cabinet style LED light will come on or just flash a couple of times. I want to be alerted when someone comes to the front door, even if they don't knock. USPS for instance leave packages without knocking and I may not know anything's there until I happen to go outside an hour or two later. Would rather get an immediate notice that someone is there without the expense of a CCTV setup. Any help or guidance on components would be appreciated. Battery powered is fine, and preferably something wireless if possible so I don't need to put holes in my walls. Thanks!

Professor Fletcher's invention of the CellScope, which is a Nokia device with a microscope attachment, was the inspiration for a teeny-tiny film created by Sumo Science at Aardman. It stars a 9mm girl called Dot as she struggles through a microscopic world. All the minuscule detail was shot using CellScope technology and a Nokia N8, with its 12 megapixel camera and Carl Zeiss optics. More cool stuff - the film's heroine, is printed. Too small to be positioned by hand for each frame, multiple versions of Dot were created in different poses with a 3D printer (so, presumably, files exist for you to print out your own authentic film starlet?) See more projects and how the 'Dot' film was made at Nokia or Facebook. Yet another video that won't embed

Hello, I'm trying to assemble a spy surveillance system that is composed of a single camera. I am still unable to find a devise that will accept a single channel BNC or RCA and recored to a large USB flash drive (also wondering if I can connect an external USB SSD instead of the flash drive as I have a 128 and 256 GB SSDs that I can fit into external enclosures so compression "H.264 or AVCHD" is not that important.). The whole idea is to strip this out of its case and install the circuit board in a camuflaged enclosure with the camera along with a DC power supply (say 12 volts). Can anybody recommend such a recorder that has the simplest controls (on/off) Also motion triggered capability would be a bliss but not critical. Best regards, Talal

We have a hidden driveway into our rental property, blocked by a large electronic gate. Need something to detect a vehicle in the drive (either a motion sensor or a touchpad type thing?) that will make, for example, a doorbell ring in the house, and a viewing camera that can handle tropical rains, that will show up on something like a baby monitor inside the home. The gate has two remotes, rather cumbersome and easily misplaced. We would prefer to keep these in the two vehicles and have a button or three in the house and garage, to enable us to activate the gate opening without having to go get the remote from the car. I would like some ideas, plans etc as although I have some electronics knowledge I need someone who has perhaps already built something like this. Any ideas, anyone?

Looking for help on my project. See image. Testing before connecting to high voltage device. Using a 3v relay triiggered by the PIR signal. As you see wired now, There is no ground wire coming from PIR. The circuit would not trigger relay with a ground wire to the PIR. When this does trigger I noticed on the relay that the LED would not go completely off. So I check to find that when relay turns "off" the PIR is still sending 2.8 volts to the relay. Not enough to trigger the relay, but enough to show power through the LED. Obviously something wrong here where the PIR or Relay are still drawing power. Can you help?

Good day to allI'm not quite sure this is the right forum for this so bear with me if it's not :PI'm looking for some info and ideas regarding a project that has been brewing in my head, but since i am no more than an initiate in all this mech and tech stuff i figured this would be a good place to find some help.I'm trying to create a low budget way to feed a 12v battery without having to use solar, hydric or wind power. Basically i want not to be dependant on atmosferic conditions so i wanted to use human generated mechanical thrust to generate enough electricity for some basic stuff. This project is to be put inside a yurt in the middle of a forest so one can have a few hours of light and maybe even enough power to charge a small laptop or a cell phone.This is my idea:I thought of using one of these old sewing tables connected to a small motor(instead of a sewing machine) in order to generate electricity which would then be stored in a battery , more or less the same process by wich a dynamo powers a bike's lamp but in a different scale.But to achieve this i still have many questions and doubts that i'm going to share with you all in the hope that some bright ideas might help me bring the project to life.-Question 1 I'm thinking the system should be composed of: Sewing table (Mechanical thrust) Motor (Generator) Some sort of electric rectifier (same function as the ones used with solar systems) 12v Battery Is this looking logical or have i missed something??-Question 2.a What kind of motor is suitable for energy production? I've been reading about this and if i understood right there are 2 kinds of motors. One kind that uses pre generated electric current to magnetize a coil wich in turn produces motion and another kind wich is built with permanent magnets. This later one would be the one i'm looking for, am i right?? Or could it be that not all PM motors can be used to produce energy from motion??-Question 2.b What kind of apliances use this kind of motors? I've just openned a broken vacuum cleaner to check it's motor but it has 2 sets of coils and no magnets, so i'm guessing it is the kind that needs electricity to magnetize one of the coils... LOW BUDGET is a key factor of this project and recycling the motor would be perfect.-Question 3 What about the rectifier... I'm guessing i should have some kind of apparatus which would normalize the energy that is going into the battery and also that prevents me from emptying the battery in order to preserve it. I'm wondering if a regular box like the ones used on solar systems would do the trick...-Question 4 I realized that these table's wheels can spin in both directions, and i'm guessing that this will have some kind of influence on the polarity of the energy produced by the engine and that this might pose some problems. Is this true?? And in case it is, any chance that the rectifier takes care of this or do i need to find a way to force the wheel to spin in only one direction?I still have many other questions but these are probably the bigger ones.I hope someone might help me with all this.Thank you very much in advance.

I need a cat/pet scarer device. Main problem: Indoor housecats scratch bedroom doors during the night. Observations: I''ve had partial success with a comercial product called "Ssscat Cat Spray Control System". It uses motion detection and a bottle of compressed air, shooting a burst of air on detection. The concept is good, but it's not easily available anymore and was a bit expensive. It seems that cats are more scared of the sound it makes than the burst of air. Ideas: I was hoping to use a "Pyroelectric Infrared IR Motion Sensor Detector Module" and a small audio speaker to make a static sound (white noise) to accomplish a goal similar to commercial solution. A sound loudness slightly above normal talking sound would be enough. The sound legth should be about one second. Maybe two LEDs lighting at the same time would also help. I would need about 2-5 such devices. They would have to be battery operated with an on/off switch. Could such devices be easily built from components? If so, I would need on finding the right components and instruction on building the device. I have only basic skills like soldering and tinkering, but I don't know how to design electronic devices more complicated than simple LED projects.

I tried to make a driveway alert system, but it has a problem. I connected a walkie-talkie to a Radio Shack PIR Sensor using this reed relay. Essentially, when the PIR sensor detects motion, it outputs 5 V which triggers the reed relay and closes the contacts, which connects the two contacts on the walkie-talkie button, which sends a beep to the other walkie-talkie. Problem: It works as planned, except that after the motion stops and the reed relay disconnects the walkie-talkie button, it will inexplicably re-connect the walkie-talkie button after about a second, and will repeat this cycle of beeping every couple seconds indefinitely. The strange thing is that sometimes it will work just as it is supposed to, but other times it wont. Other details: The PIR sensor is powered by a 9 volt fed through a 5 V regulator so it gets steady voltage, while the walkie talkie is powered by the regular AAA batteries. I am a novice with electronics, so don't rule out that I may have made a simple mistake.

Hi guys I hope this is ok to ask about as I have followed Instructables for ages but not used the forum part before. I have a bit of experience of arduino projects and doing basic sketches for them but nothing as ambitious as this so am seeking a bit of advice if possible. I'd like to be able to have a droid/robot's head that can rotate to focus on the direction of a sound, then if it sees a person once looking in the direction it heard the sound, to then roughly track them (move its head) with a camera. I'm fine with motorisation and that side of things, but I'm not sure if this sort of fairly elaborate setup would be possible with an arduino or would need something more powerful like a rasp pi? I'd imagine that I would need an array of several mics as inputs around the bot in a 'circle', and code that can estimate the direction by means of the signal strength from the mics when it hears a noise. I think this might be something I can manage to do, but then it'd need a suitable camera and a means of tracking and I've no idea how the tracking side of things would work with that. I'd be grateful for any pointers to get me going thanks. It's not something I could do without help but hopefully doing it bit by bit and with some advice I'd be able to do this, as I would really love to make it work! Many thanks! Jim
