No-IC design ...

[Jim Cheetham]

Here's a nice thing - a digital clock using only discrete components, no
ICs ...

Lots of interesting design decisions. I like these sorts of devices because
of their transparency and verifiability. Paul often has to remind me that
the complexity of driving USB is so high that I can forget about him
attempting something similar for OneRNG :-)

But I wonder what we could do with a serial-only device ...
