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.

This circuit based on Atmel’s Butterfly Evaluation Kit provides control on the main functions of an electroplating bath, that is the temperature and the current flow. To achieve optimum plating bot the temperature and the current flow play a major role in the electrochemical process, and they have to be kept within a defined range. Basically the controller digitally implements PID algorithms for current and temperature control.

The High Altitude Rocket Telemetry Payload system is a flexible flight computer for mid- and high-powered model rockets. The ATmega169 based system features a GPS receiver, a wireless data telemetry downlink, and a pass-through bus architecture that enables you to configure a payload for your specific flight goals. For those rocket geeks out there, this might be a interesting project. I do know that most of the rocket parts are buy-ed from the shelves of the hobby stores, but you should definitely try build some of the parts, you will get more satisfaction when you see it fly away with the parts you fabricated.

This “intelligent” power supply was designed specifically for embedded systems. In addition to its numerous useful features, the ATmega169 based power supply can provide any voltage from 0 to 5 V with 10-bit resolution.

The Aircraft Visibility Remote (AviaRy) is an RC lighting system for model aircraft. The ATmega169-based system features a remote keypad that’s connected to the pilot’s transmitter. An on-board controller is connected to the aircraft’s receiver.
