Raided an old 70s Pioneer cassette deck for parts. Incredible construction quality - all discreet components, single LEDs mounted on individual circuit boards with wirewrap connections, huge thick pins, big globs of solder.

All that work all those years ago, reduced to this... It's the tape counter connected to a broken Turnigy TG9 servo 'converted' to 360 degree rotation, triggered by the Arduino.

Now I need a project that would benefit from a way to inaccurately count up to 999. While making a racket.
