And here is another infrared receiver, although its name says its universal that doesn’t mean the other Infrared Receivers aren’t. The project page first presents a MCU version of the receiver based on several types of PIC’s and than the symplified version without MCU, the one i also wrote about here. The goal is the same as for the other infrared receivers, to control your computer with any remote controller you have (TV, VCR, CD or Stereo).

USB-IR-Boy is LIRC compatible USB bus infrared receiver hardware using Motorola MC68HC908 MCU. This project aims to be the new standard home made IR receiver with low cost for all PC hardware that has USB. In my opinion this project its not better than other infrared receivers, its just different by having USB connectivity and being based on a Motorola MCU. This project also has an extra item, the LED indicator, which blinks when signal is detected. Everything you need is provided on the site so you could give it a try if you need a infrared receiver.

Here is another useful project based on the Atmel’s AVR butterfly kit. We should define “useful” though, this circuit was designed to trigger almost all Canon SLR cameras from a distance, so first of all you should own a Canon SLR camera and than carry on with the project. The circuit is controlled by an ATmega169 and powered by a 9V battery.

Sivan Toledo writes:In this project I created an infrared (IR) link that provides bi-directional communication between the NXT and the new Power-Functions system, which consists of a battery box, motors, a remote control (an IR transmitter) and an IR receiver that controls the motors.I previously built an IR transmitter for the NXT which used an MSP430 microcontroller and which was able to send Sony IR commands (the specifications of this protocol are widely available). So why the need for a new IR transmitter ? Well Sivan wanted to achieve a couple of new goals:
- To analyse the Power-Functions IR protocol, for which no documentation is publicly available.
- To build a system that could not only send IR commands, but could also receive and decode them.
- To experiment with AVR’s, another family of microcontrollers.
So he build the project, and he published it with lots of pictures and details on he’s page for anyone who wants to build it.

Based on a simple basic Idea, this proximity sensor, is easy to build, easy to calibrate and still, it provides a detection range of 35 cm (range can change depending on the ambient light intensity).This sensor can be used for most indoor applications where no important ambient light is present. For simplicity, this sensor doesn’t provide ambient light immunity.
