Can I use a VHS as an IR filter?
Question by jbaker22 | last reply
I have probably asked enough dumb questions already but I think you could do this. I have an old TV remote control. If I would split it open and disconnect the IR and solder a USB cable to it would it work on the computer? (I would have put batteries in it too.) A program would control the remote.

Hello, Some friends asked my wife to do a birthday cake for a girl of eight years. With her Âage she is crazy about princesses. Well, what came to mind was that despite having done many projects with Arduino i had never applied electronics in a cake. So we decided to join forces and add some light (RGB LED) and movement (DC motor controlled with an L298) to the cake. Here is the link to the video: http://www.youtube.com/watch?v=TmL1nR2-uEQ&feature;=youtu.be

Hi all, So I've been searching / reading up on IR heaters and I can easily find IR bulbs /heaters, at 30W+ but the bulb's are pretty big (in regards to what I want). Is there not any smaller-scale /electronic componets for producing IR heat? I know there are IR LEDs but is that the same thing? I'm a bit lost and I swear I came across something before that had an array of small scale IR heating componets, but quite frankly I dont really know what I'm searching for, in regards to a correct name etc... Thanks in advance :)

I recently ripped apart a Sky+ box that was out of use. Of course, it contained many parts. Quite a few tact switches, a few LEDs, a lot of capacitors, lots of resistors. One of these parts was a little metal cube with a black sphere protruding from the front of it. This is the IR receiver for the remote. I wish to incorporate it into another project. The first problem is I don't know how to use it. It has 3 "legs" - 3 metal contacts. The second problem is I can't easily experiment with it as I inadvertently destroyed my breadboard earlier. A new one will come as soon as I can manage, but until then..... My question is this - any ideas how it would be used? Thanks in advance, ~H4ZZ

I have been wanting to make night vision for a while and I get the question. How do I make an IR illuminator? Well I can buy 15 long range IR LEDS or I could buy a pre-built one for under $20. I have searched everywhere and still can't find what i'm looking for.

Hi, im looking for a way to detect distance (around 4 feets) using IR. basically a person will carry the IR transmitter and walk around until he comes across an IR receiver. the receiver is connected to a buzzer where the buzzer will emit louder sound as the user getting near to the receiver. can this be done by using ir transmitter and receiver led? any other better suggestion is welcome thank you for your reply
Question by bhan1992 | last reply
So I have been working on an airsoft tripwire type thing. I have the circuit entirely finished. I am using an infrared photoresistor and the one problem I am having is that I can't seem to focus the beam from the IR leds very well. I have three of these (http://superbrightleds.com/specs/IR2030_specs.htm) at my disposal. The IR leds are a pain to line up with the resistor on the circuit. So I ask you, what do you think I could do? Ideas on better ways to focus the beam as well as perhaps ideas for replacing the photoresistor are appreciated. The IR photoresistor came from radioshack. I'm pretty sure this is it: http://www.radioshack.com/product/index.jsp?productId=2049723?
Question by DesChamos
The cheapest way of wirelessly controlling a robot is IR, right? I'm in need of help for a schematic for an emitter and a reciever (this will be my first IR project). Please don't tell me to google it because I've been looking around and all I've found were vague schematics. I'd probably want to use a 555 timer for the emitter, but the schematics were vague again. For the reciever would I have to use 4, along with 4 emitters to drive 2 motors independently? As in Motor1 front and back, Motor2 front and back?

What do you think about a IR beacon on a keychain that flashes every 10 secs or so while its not moving. (And optionally flash brightly before going into energy saving mode turns when touched) essentially you can use your mobile phone to locate your keys when lost.

Hi Guys & Girls Obviously, i am new to this and my electronics knowledge is very limited. Let me first explain what my desired outcome is and then proceed with the questions i have. In the schematic below i connected two circuits that i found. One is a infrared receiver and the other a flip flop. With that, the following needs to happen : when the user presses a button on a IR transmitter aimed at the receiver circuit in the schematic it is sent through pin 3 to the flip flop circuit which in turn puts the relay in a (permanent) ON state. When the user presses the same button again, the process is repeated and puts the relay in a (permanent) OFF state. So bottom line a 1 button/channel IR press on press off switch to switch my 12v circuit on/off. Here are my questions: 1. Is the receiver circuit correct as i have drawn it i.e. will it work? 2. Is the flip flop circuit correct as i have drawn it i.e. will it work? 3. Where i have the red circle : 1. Is the connection between the receiver and flip flop circuit there correct? 2. Do i need another resistor there? 4. Do i need a “floating resistor” as a R5 around the relay and how does the practical application of this look (on all the diagrams i look at it’s drawn around the relay going from an input to an output on the same wire......does that mean that on the pcb it will run parallel between the “pos+ and neg-“ going into the relay?) 5. Is my relay connection correct within the blue circle? 6. All and all, put together will my circuit work as expected? I know there are probably a whole bunch of ways to achieve the result i am looking for and being a noob, this might be the most impractical(i don’t know), but the reason i went this route is because i have these components available to me and if at all possible, i would not want to go and buy other components. Thanks in advance for any help provided. I find it much easier to learn by building the circuits and then seeing with a multi meter etc. what the effects of each component is than reading through all these books and trying to cram everything into this thick skull of mine Schematic Component Values : R1 = 220k ; R2 = 100k ; R3 = 10k ; R4 = 10k ; R5 = ? C1 = 1uf ; C2 = 0.01uf ; C3 = 10u Rx1 = Any tsop/similar U1 & U2 = 555 timers

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?

Hello everyone, I'm trying to find a way to detect a IR source -a LED- from 100m. I only need to detect the source, I do not need to transmit data. When I turn the camera towards a IR source the software would put an icon on the source BUT without seeing the beam. Namely, the led should look like it is off but the icon on the image should indicate that it is a IR source when it is on. Thank you all!

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?

hey guys, im looking to build a IR triggered LED strobe. in the smallest possible size i can. it doesnt have to be from scratch so if anyone knows of a cheap trigger on a toy i could use that would be great. im looking to build an IR triggered strobe for an airsoft gun i have. the idea is to strobe an led (most likely a UV LED) every time an airsoft pellet trips the trigger. these pellets are glow in the dark so in essence i will be making my own homemade airsoft tracer system. these units are about $70 so if i could do this for free or much cheaper i would be thrilled. i know there are things out there i can use but im drawing a blank right now. i have makers block or something. here are a couple links to YouTube vids that explain the concept and more along the lines of what it should be like. at about 1:50 in the top video theres is a good demonstration on its workings. <br> <br> any part suggestions or ideas would be awesome.

I was wondering if anyone knew of any HD webcams that could be used as a standalone camera without the computer, or ones that could be modified for such a purpose. I was going to use a standard Sony digital camera, but the key issue there is that glass elements are absorbent in the short IR range, and so kill most of the effect. One element is not that bad, but when you have the 8-10 of varying thickness in the camera's zoom lens assembly, you lose a lot of IR light. I need the IR effect for demonstration - for example, under IR light, veins and vessels in your hand become a lot more visible, as well as the ability to perceive "heat" becomes a lot more capable. If anyone could either help point out a HD webcam that would work or help me make a standard "cure-all" lens it would be extremely helpful. By cure-all I mean the lenses you find on cameras such as disposable 35mms, ones that either don't have any glass in them or only possess one element and have a focus range of roughly a foot and a half to infinity.

Hello Instructables. This is my first post and would like to begin by saluting the work you all do, I love receiving the email at work showing the weeks projects. My problem, that I hope somebody has a solution to is this... I am building a false wall to house my fish tank and TV, ps3 etc however my amplifier is too large and does not fit into my project. The only way round this is to house my amplifier in the loft. In the wall I want to place the IR remote control Sensor. I don't really want to pay out for those 'eye's' you can buy online (nor do i think they would be compatible with my model of amplifier) so was wondering if i could just use some ordinary electrical cable to extend the sensor? I was worried cable might not allow this as it would probably add extra resistance to the circuit. Does anybody have a solution or suggestion that involves spending little or no money please? Thank you very much! Frankie

Hello everyone! I'm looking to get some advice on how to build a Wii-style controller for my PC. What I want to get it to do right now is just to move the cursor around on-screen, however I want to eventually turn it into a gun-style controller for use in shooter games. Anyway, I was wondering what the best way would be to track the movement of the gun (i.e. aiming). My idea was to use IR emitters in the controller and place 4 receivers at each corner of my monitor, which would all be hooked up to the Arduino. Then, I would use the data from the receivers and the strength of the signal on each receiver to calculate that into a position on the screen. The main problem is that I don't know how to measure the signal strength from each receiver, or even if this is possible. Also, if anybody has a simpler solution (other than buying a controller ) please post. I sometimes like to over complicate things

Question by Daniel Deacon | last reply
With the new Infrared laser pointers etc. there is no way to tell if light is on or not. I think there is a need for a IR laser light detector that is small enough to fit in your pocket and could be clipped to your shirt. If a IR laser was pointed in your direction the sensor would chirp or make a noise. I've noticed several places selling IR laser pointers. I think they are dangerous and very little use for them, since they are invisible. Anybody want to make one? If you do I want one.

Hey I am in the process of trying out a circuit that will act as a portable pluse checker. I was hoping on using the IR LED's to reflect light from the clot of blood and if it bounces off (which it should) it will be picked up by a IR Detector. The whole project rests on the question if the IR light will bounce off the blood in my veins, and if it will be picked up by the detector. So i ask you....will this work? Please keep in mind I am trying to keep the project simple, so no programming would be great!

I'm trying to build a guidance system for RC airplanes and drones. This should work by sending different IR signals to different locations in the air, so the drone will pick up signals specific to one location, enabling it to know where it is. (Like a mini, simplistic VOR, if you know about aviation) I'll probably use an Arduino on the ground with the transmitter, and a Raspberry pi onboard the airplane. I would like the IR signals to reach as far as possible, so does any one know of any small, high power IR LEDs? Also, if you have a good idea on how the signals could be accurately focused, so they line up next to each other without over lapping, let me know.Thanks!
