Hamster got loose?
Have a bunch of surplus elecronics?
Time for some Hamster Sensing Technology.
Step 1: Assumptions
The hamster is coming out at night and eating food left somewhere.
That big pile of misc electronic crap you have includes:
- Something that will sense a hamster.
- Something that will wake you up.
- Something that will interface between the hamster sensor and the waker upper.
