class D amp modules and a programmable digital signal processor,
and "modernizing" an old 1960's Philips tube radio with a
Raspberry Pi, DAC and amps hidden inside to allow streaming
of music from the net. The tricky part has been the careful
tuning of light dimming algorithms to make LEDs simulate
tubes warming up...
