I think this is probably the kind of circuit that the "Backoff" thing uses.
If you're sugesting I try to build something like this myself I think thats a ways over my head. I'm pretty comfortable with wrenches but electronic stuff - especially small electronic stuff - is out of my comfort zone.
I'm actually liking your first suggestion - tapping the brake lever - more and more.
I'd still like to hear from anyone who actually has something like this on a bike and is has used it for a while. If you think it makes any difference from a saftey standpoint or is just a gimmick.
