When the girl is away

From the BeerLauncher site:

 

Here is an image of the circuit board I had made from expresspcb for the beer fridge. It uses an ATMEGA8535 for the main microprocessor, 3 intelligent H-bridges to control the motors, a Darlington transistor array to control the solenoid, and a MAX232 for RS232 debug io.

 

I have new found respect for the engineering program at Duke. The control circuit for the solenoid is Senior year Electronics II stuff, nevermind everything else that went into it. That video brought out my inner nerd.
