Steve....I hope your realise you now have to sign up to do one of the mod instruction courses for the touch operated power stick.....lol.
It's mostly the same procedure as for the NicoStick. There are lots of circuits for touch switches on the net, but I like my design so I'm keeping it secret because it's not so simple to get the sensitivity right and make sure that the final power though is fully efficient (critical in a VP). To be honest, it would be of far more interest to a manufacturer than the average modder. But I can make a few modules if anyone wants to try it in their own mod.
