Off-topic, but cool:
A guy selling kits to make a all-parts-exposed digital wall clock that
uses *no ICs* and *no crystals*. You build it yourself, 1250 parts to
solder onto a custom board. Too pricey for me, otherwise I'd love to put
ICYW, I dug around the FAQ and he is cheating a bit: he's using the 60Hz
of the AC as a timer source.
Hmm, since it plus into AC, does that mean touching some parts of the
exposed circuits might give you a nice zap?
