Re: Stroboscope
I remember a project to make a neon stroboscope using a helical neon tube (called a 'spiral neon' in the project) that I think came from Service Trading in Chiswick. It was connected to a car ignition coil. I can't remember the rest of the circuit.
I think it was in an issue of Practical Electronics in the late 1970s and was on the cover. I can go through my paper magazines if you can't find it and it sounds useful.
