This project, named as Bsensor, was designed to overcome a difficult task for a small mobile robot in indoors environment; to solve the absolute positioning problem with few computational resources. Several methods exists, but most require triangulation from several sensors and positioning is not easily calculated as it is required that the robot receive [...]

If you are looking for simple ON-OFF remote switch for your home appliance then this InfraRed remote control circuit is suit for it. This circuit allows you to turn on/off your home appliance (lamp, ran, radio, etc) using any type TV, VCD or DVD remote control with range up to 10 meters. The circuit [...]

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 [...]
