IR protocol analyzer is universal software for automatic decoding infrared remote control protocol packets. To capture infrared signal from a remote control, it uses microphone input of a soundcard. The hardware you need to start decoding is minimalistic and easy to build, just plug a phototransistor to input of your soundcard.

The project shows you how to build ballistic chronograph based on PIC18F13K50 Microcontroller. The project only been tested with a paintball gun and it is relatively simple to make. It also can record the rate of fire at which a device is firing. The operation of this projectile velocity meter is rather simple, there are [...]

The Remote Video Control System will allow a remote user to fully control a separate video camcorder with a control board through InfraRed signal. The remote user has all the capabilities as if they were using the camcorder in-hand, including pan, tilt, zoom, Record, Display on/off, Tilt Position indicator, 4 speed settings, and even a [...]

This Infrared remote control for Nikon cameras built based on AVR ATtiny13V. The circuit is very simple. It consists of Atmel tiny13V, a button, transistor, resistor, IR diode and 3V battery. If you want simpler circuit, you can connect the IR diode directly to the ATtiny13V, but that will limit the LED current and therefore [...]
