@paulgit @streakmachine Happy days!
My peak was the BBC Micro - making stuff from scratch like:
- a digital joystick (5 microswitches),
- an analogue joystick (2 rotary potentiometers, axes arranged at 90 degrees, plus a microswitch) and
- a 'graphics tablet' (2 potentiometers, one fixed to the baseboard, both joined together via perspex arms, and a microswitch at the crosshair target.)
Built-in A/D converters and a good knowledge of trigonometry and BBC BASIC made it easy.
I'll never recapture that spirit exactly, but it'll be fun on the way to 'failure.' :)
