lol, I got it but you left out a word.Hero999 said:Perhapps it's just a lucky your anit-coincidence circuit worked.
Hero999 said:Rubbish!
How?
Please annotate your schematc and show us how it works.
The gates are all connected to +V via the bulbs ao they will burn out.
The switches are all connected in series with the cathodes.
The anodes are all connected to +V via 1k.
There is a circuit very similar to this that works. My guess is you've tried to draw it but got it wrong.

Muki got the symbol correct, but his circuit won't work.
A PUT works as an oscillator by having the charging capacitor at its Anode, making a trigger voltage reference with a voltage divider at its Gate, and having the load to ground at its Kathode (spelling mistake because it is K).
When the capacitor's charging voltage at the Anode is a little higher than the gate voltage then the PUT conducts the capacitor's charge into the load.
Good, but a schematic is useless without a bill of materials.musthave said:here is a quiz master from 1991 PE hobbyist handbook
