Anybody have any suggestions for interesting things to do in Cambridge on one's own at a weekend? Preferably things which are cheap, and absorbing enough to take my mind off other things.

Crystal earphone on the radio bit; that's the ticket. Takes hardly any power at all.

I'm fairly certain that I have read of a hand charged mobile phone charger. You basically want a Fuck Off spring and a few gears and small motor. And then the current regulation stuff surrounding it. I still think the best bet is to cannabilize a wind up radio, though, to get the dynamo bit out of it.

Ah, but I don't want earphones on this radio, I don't mind competing sounds, but I don't want something that actually blocks out traffic noise, if I'm cycling.

The wind up radio would do that anyway; as it is designed to support speakers. The trick would be to hook the pedals up to the handle so that it recharged while cycling. The extra problem is now to produce a regulated current of adequate size for the phone charger.

This is worth an LJ entry on its own.

Um. I can add you to my friends list if you want to make the post?
