Electronics

So…
I’ve started tinkering with electronics, which I haven’t done in a long, long while. I was never any good at it, but I do have a crude, basic understanding.

This is the first circuit I made, a simple 3v to 12v booster circuit.

It takes power from a single cell 18650 battery (3.7V) and boosts it up to ~12V when pushing the button 😉
