A dumb bistable

A project log for DYPLED

a thin LED display in SIP module format, much better than TIL311s to visualise your computer buses

I know I could have done this with a pair of transistors but... The HC04 is more handy.

Just to be sure, I implemented the circuit and it worked (as soon as it was correctly wired, as usual :-P)

I love how simple it is. It's easy to look down at simple, dumb inverters but a few resistors and they become very versatile :-)

And to be honest, it got on tracks thanks to #Charleplex Xmas Tree without uC (@K.C. Lee will even recognize the oscillator topology of the other part of the circuit)
