What was your first circuit? Do you still remember it?

When you mentioned telegraph, I pictured you in a top hat and tails, working by lamplight 😁

Before electric & pneumatically driven ones, drills, were human driven, with a handle you turned on the side, or crank-like "brace & bit" style.
Until rechargeable drills appeared, it was often more convenient to use such drills rather than dragging heavy power cords around.
I cannot imagine any applications for horses in drilling. ;D

I keep planning to revisit those "regen sets" to see  if they were just crap designs, or if it was my poor construction techniques.

I don't usually quote myself, but I started digging through the old box full of "valves" in the back shed, & found a bunch which would work for those old projects---- maybe it is telling me something!

Y'reckon?

AndrewNorman:
For me it was the circuits in "Dick Smith's Funway into Electronics vol1".

Got given the book for Christmas, got the LED flasher working and then spent many hours trying to get the damned crystal radio to work. Never did manage, but it did get me interested in the subject.
Kasper:
Mine was a battery, 2 wires and a light bulb following instructions in elementary school.  Then I made up my own circuit: a battery and 1 wire.
