ATMega8 Based Brain Machine

The project is an improved version of a former brain machine where the improvements include selection between multiple stored frequencies, importing of gnaural schedule files, arbitrary frequencies, and sine-wave audio.

POV Light Display on Bicycle Wheel

The project produces POV displays by using an Atmel ATTiny861 microcontroller to control 48 LEDs on a bicycle wheel.

Homemade Infrared Receiver Known as USB-IR-BOY

The project utilizes Motorola MC68HC908 MCU to create the USB-IR-BOY which is an LIRC compatible USB bus receiver hardware.

Battery Pack For USB Devices

The project is designed to power a device via USB cable using two standard AA and some electronics to form a battery box.

Critter Device Known as The Coat Hanger Walker

The project makes use of coat hangers to build a little critter as an ingenious hardware hack that illustrates a number of principles of bootom-up, BEAM-friendly robotics.

Building the Mini Direct Digital Synthesis (DDS)

With the use of the AT90S2313 and a resistor network, this project can create a simple version of Direct Digital Synthesis (DDS).
