The flying cow


Electromechanical drive for flying cow in theatrical spectacle were required. The drive have autonomous power supply (SLA battery) and wireless remote control.

Technical solution

Arduino Duemilanove with Atmega328 microcontroller onboard is used for drive controlling device. Infrared TV remote is used as remote control.

The drive itself were built from two car lock actuators. TIP122 bipolar transistors are used for amplifying control signals. These transistors are used in 2-channel switch.

To protect transistors from overheating, each of them is mounted on heatsink.

Algorithm and Arduino sketch

For the proper build, IRRemote library should be put in the library folder of Arduino IDE root folder.
