IR to USB

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.

IR Cake.

Hello, Some friends asked my wife to do a birthday cake for a girl of eight years. With her ‹age 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

IR heaters?

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 :)

IR Receiver

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

IR distance sensor?

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

IR Beam issues.

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?

IR Robot Control

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?

IR Switch. Will this work? Answered

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

How to make a circuit with an IR receiver turn on with an infrared remote control?

We are currently having a Research project in our English class and we thought it would be nice if we tried a research regarding electronics because me and my parter are both interested in electronics.  However, we are both beginners when it comes to electronics. Is there anyone who can help us with the following: A. Building an IR remote that can send a signal to the IR receiver to momentarily turn on (kinda like a push switch) B. An IR receiver that will be connected to a circuit to allow it to momentarily turn on or off based on the actions of the IR remote C. A fabric/system that could give a sudden "shock" to the holder when turned on kinda like the gag shock pens. D. Schematics for the IR receiver circuit I don't even know if this project is plausible but if anyone could help, we extend our deepest gratitude :)

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!
