Re: Will this circuit work?
Thanks for taking so much time to explain things to a newbie. Here's a couple more possible numpty questions.
Would it be possible to dump all the circuitry going into Stdn and put the switch between the battery and ground instead?
What made you choose a capacitor over a battery?
Re the switch; instead of a 10 minute timer, would it be possible to use a very low power transistor to switch it off when Vcc went below 0.8v. It would probably need some sort of logic where it went off if the dynamo was off and the standlight was off, then it goes off, and only when the dynamo starts, does it comes back to life. (not really thought this through yet). Might there still be a tiny drain on the battery?
