The Wiimote makes a perfect control system for a fire fighting robot.

It has IR sensors which can detect a candle and a bluetooth transciever to communicate back to a host computer. I use a boebot as the robot platform, an arduino, wiimote and a Linux computer.
The wiimote uses its IR sensor to find the candle. […]

This is a simple PC voltage oscilloscope using only a PIC12F675, a 20MHz oscillator, and a RS232 level shifter. The PIC takes a sample on GP2, immediately sends it to the PC at 115,200 baud using an software asynchronous serial routine, and repeats. It sends a 8-bit value that is read by the Visual Basic […]

This simple game console if we can say so is built under AVR Atmega168. Game display is made of 16

After the recent demise of our multifunction signal generator, we decided to make one of our own.?? The circuit uses a PIC16F870 (about $3), an R/2R resistor ladder network (for a real fast and cheap D/A),? and a few other parts.
You can check out the schematic and the current source file.? Also the object (hex) […]
