When Ivan changed his TV provider they required the use of a SetTopBox(STB) as a receiver. Since it had HDMI output, he decided to use an old Philips 230C1 monitor as a TV screen. The monitor, however, was not controlled by the STB and had to be switched on and off manually (not via the […]
Chris from PyroElectro writes informing us of his project to achieve Motor Control via Proximity Sensing. He describes, “In this article, we go step-by-step through the process of understanding, designing and building a system that uses an infrared proximity sensor for input, correlates that input to how far away an object is from the sensor […]
If you have an IR capable webcam lying around, here’s an interesting open source project you may want to try. “The ITU Gaze Tracker is an open-source eye tracker that aims to provide a low-cost alternative to commercial gaze tracking systems and to make this technology more accessible. It is developed by the Gaze Group […]
We stumbled across this protocol analysis software aptly named Protocol Analyzer. “The Protocol Analyzer is a small tool that can catch, analyze and decode “slow” pulse based protocols. Typical examples are IR-Remotes or RF-Remotes. It uses the microphone input to read the signals. Since this is almost always available with drivers across operating systems, this […]
Chris from Pyroelectro developed this all-digital-hardware Theremin. He descibes, “The Digital IR Theremin uses comparators, digital logic, and a single 555 timer for tone generation. When you wave your hand in front of the infrared proximity sensor, it outputs a tone with varying pitch depending on how far away your hand is from the sensor!” […]
Jack Chalkey, Creative Technologist with Imagination Labs, has posted an outline of their Arduino based project for Social Media Week. The project was conceived by several lab members who returned from EMFcamp 2012 with some tech and an idea for badges. “The tech was badges (more like lanyards) with an onboard Arduino Leonardo, RF module, […]
Kerry reverse engineered the infrared remote control protocol used by a Syma S107G remote controlled helicopter. He took the remote control apart, probed it with a scope, and analyzed the signals: This tiny remote control helicopter is a rather amazing toy. Not only its movement is very stable, but the rotor speed, forward backward movements […]
Chris from Pyroelectro has posted this tutorial detailing the use of an IR transmitter and receiver break-beam pair to measure the speed of a fan. The IR components are used in conjunction with the Arduino UNO which processes the break-beam interruption counting with the result displayed on a 16×2 LCD display. You can get the […]
Ken Shirriff has posted an Arduino-IRremote library. “This IR remote library lets you both send and receive IR remote codes in multiple protocols. It supports NEC, Sony SIRC, Philips RC5, Philips RC6, and raw protocols. If you want additional protocols, they are straightforward to add. The library can even be used to record codes from […]
Lumpeenjussi is using a BeagleBoard to run a web server that controls his air conditioner via the USB Infrared Toy transmitter. An app on his Android phone interfaces with the server so he can control his AC from anywhere. Via the forum.
Matt Richardson over at MAKE presents this cool solution to listening to the audio portion of the garbage overload known as entertainment news. He has design this project known as Enough Already which mutes the audio portion of a TV program when certain words are mentioned. The hardware consists of an Arduino and the Video […]
Chris from PyroElectro writes us with this useful project to communicate serial data over an infrared link. Here’s an article that explains how to create a wireless infrared transmitter using an IR LED and a wireless IR receiver using a phototransistor to make a communication system. Asynchronous serial is transmitted over this link at 9600 […]
The Public Laboratory for Open Technology and Science(PLOTS) provides this detailed tutorial on hacking a Canon Powershot A490 digital camera to allow it to record images in the infrared light spectrum. The mod involves opening the camera and removing the infrared light filter. To view only infrared light, replacing it with a piece of exposed […]
Chris made a mutant video game controller, console, and more, all wrapped up in a small project box. Check out the list of features: Propeller Board USB, Net Server, BlueSmirf Bluetooth, X-bee, DeadOn RTC, Lipo and onboard charger, On board USB-FTDI-Serial for both Prop and LCD, 4 gigs of SD card space (2 cards), IR […]
This article from Radosław Kwiecień’s website shows how to decode RC5 IR signals from a remote control using the 16-bit Timer1 and INT0 external interrupt input in the ATtiny2313 Atmel AVR device. All code in assembly in available in a compressed file.
Dmitry Grinberg had a few PIC12F1840 MCUs lying around, and wanted to use them in some type of IR remote control project. He decided to construct a remote control mood light using the PICs in both transmitter and receiver. Four high-brightness LEDs (White, Red, Green, and Blue) are used to combine to form different colors […]
Siliconfish used to build IR cameras for a living, so he knows something about the effects light of various IR wavelengths can have on a camera. When his town installed photo cameras on the traffic lights, he decided to experiment with an array of IR LEDs mounted on a license plate frame to see what […]
MickM tipped us to a treasure trove of infrared remote control info at JP1 Remotes.
Here’s a video of Jeri Ellsworth’s latest project for element14, a shooting arcade game using the MachXO2 CPLD. The game is simple in principle: use an LED light gun to shoot the light sensors representing the bad guys when they appear at windows in the target house. The implementation is more challenging, with the heavy […]
IgorPlugUDP is an ethernet-enabled infrared receiver. This is an old hack that kmmankad brought up in the forum. What makes it really cool is that the ethernet is bitbanged using nothing but the bare pins of an ATMEGA168. It is transmit-only, it cannot receive network packets, but that’s enough for a lot of projects.
