BasicPCB customer shares printed circuit board project: Spectrum Mouse Trap
[Original Image & Post Source]
Spectrum is an electronic mouse trap 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.
