I scored an old oscilloscope today. It's from 1982 and made in Victoria by a company called BWD. It's in pretty good nick, though the screen seems to flicker a bit when turning various knobs. I found a service and repair manual for it too. Apparently these are easy to repair. I can get three more if I want too. Now to make a function generator. Maybe I'll use that Arduino kit I've had for ages. I found a thing on the internet using a Arduino nano.
