Spectrum Mouse Trap

Spectrum is an electronic mouse trap I designed and built for EE90, an analog circuits project class at Caltech. The trap uses photodiodes to sense when I mouse is on the trap. IR LEDs illuminate the photodiodes, and when a mouse steps on the trap and blocks the light the trap triggers. A latching relay holds the trap in the triggered state until it's manually reset.

 When triggered, a solenoid fires and raises a curtain around the base to trap the mouse. Two LEDs connected to an astable multivibrator at the top blink when the trap is triggered. The PCBs were printed by a manufacturer called BasicPCB: http://www.basicpcb.com/
