Retro Blinky

Retro blinky

This was the very first electronic circuit I assembled 40 years ago. Now, in 2020, I designed it properly.

I hope it would help someone of the next generation to learn the basics of electronics more easily.

In practice it means you keep the "https://pintergabor.eu" link printed on the PCB, and do not delete it from the documentation either.

As it is impossible to make only a few samples of these small cards, I have plenty of bare PCBs available in the shop for ridiculously low prices.

Today, with a little better and cheaper components, it looks like this:

Retro-Blinky-Simple-SCH

Or, with NFETs, it looks like this:

Retro-Blinky-Simple-SCH

And a more interesting variant, with an additional resistive touch sensor:
