Miffy surprise

Fig.1: real bunnies. Once upon a time (in a galaxy far, far away), Miffy emerged as the next evolutionary step out of these proto-rabbits.

Fig.2: Miffy.

Fig.3: "what is playing now" bush, front. While Miffy performs on stage, the viewers would surely like some indication of which song is currently playing. Hence, this bush; LEDs indicate 1 out of 3 'main' tunes, or an 'intermission'-tune.

Fig.4: "what is playing now" bush, back. Wiring is modest; 4 wires for 4 LEDs, with common kathode.

Fig.5: Coke. When time is a factor and sleep a luxury, Coke is vital.

Fig.6: lightshow-bush, front. Nice LED 'walklight' (what's this called in English?) is displayed here with a few different modes.

Fig.7: lightshow-bush, back. Wiring is slightly less boring, with 4 series-chains of 4 LEDs each.

Fig.8: the board. Not extremely interesting, is it: a relais, an MCU, a transistors for each of the 4 'walklight'-channels, a zener, and a few resistors.

Fig.9: a snug fit. Everything is designed genau wie die Profis as they say in France, to fold together into a box-shape. Electronics is hidden under the 'floor' on which Miffy stands.

Fig.10: action! So ok, victim opens/unfolds the box, presses button, and is amazed. Mission accomplished. Congratulations.

So... WTF?!

As a surprise-gift for some combined events (among which, a birthday), I thought it was fun to make something that involved electronics at least to a minimal extent. It was not until later that I found out that such a thing is called a music-box and is available in the stores - but ok, this would be a customised music-box.

Disclaimer

Basically, I don't have time nor mood to answer/respond_to non-constructive comments. E.g...

• code is not perfect, ...
• note-frequencies are not perfect, ...
• my cardboard-skills suck a bit, and...
• yes, the used tints of spraypaint are way off from what was intended, ...
• it still smells of spraypaint even now, and of course...
• electronics are crude, and may hurt the delicate designer's feelings.

So there. Really, I'm a nice guy, but really, get off my back. But constructive comment is of course always welcome! :-)
