Parallax Propeller guru Phil Pilgrim has posted this IR sensor/discriminator project on the Parallax Propeller forums. “Almost everyone here is aware of the advantages of modulated IREDs for rejection of background IR fluctuations and line-frequency noise from artificial lighting. Typically, … Read more
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 … Read more
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 … Read more
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 … Read more
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 more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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, … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
