What to make for Valentine's day? A bare perfboard with a Valentine's chaser (basically a 555-chip, 4017 decade counter and a handful of leds) doesn't look too impressive. That's why I made this heart shaped wooden box with a laser cutter. Both printboard and battery fit nicely into the box. Three bolts, nuts and washers to finish the job.
The file for the laser cutter (.svg) can be found here.
And here is a 3d printer file (.stl) of a little dock for the heart.
