"Feed me Seymour" - Rocky Horror Picture show homage.

As gift to a producer of a touring show, I made a small device that displays the famous line in a faux-neon style with cobden filaments.

The biggest challenge by nautical miles was designing and printing the cradle in which the filaments sit. They're such tightly ducted channels that, well, yeah it was super complex and I'd think of something different next time but it glows gloriously brightly and they loved it!

It has a whole slew of circuitry for USB charging and voltage conversion (down to an irritating ~3V) plus BEM circuitry for my DIY battery pack with Li-Ion cells. Again, probably overkill in hindsight but after charging it does last days and days.
