THanks Paul. That is a really neat idea, and it deals with the frog polarity issue at the same time.
Checking on Amazon and RS Components it looks like you can get switch travel of between 1.5mm and 2.5mm which i’d have thought was idea.
One of the commenters in the youtube video noted that you needed to make sure that the switch you buy breaks contact with one wiper before making contact with the next or you will get short between the rails. Amazon components dont mention this, but a few of the datasheets on RS did note that it ‘broke’ before ‘making’
I’m definitely going to try this. In fact i’ve just found an old toy with a switch that i can scavenge…. Hopefully i can try that today or tomorrow… exciting!
Cheers Dunc
