I'm sure we could source a couple of crappy old phones to mutilate between the lot of us. Those slim, lipstick ones would do the job. Rip off the plastics and encase in latex/rubber compound. Stuff in the seat tube by the bb. I was thinking maybe as a sting operation but linked to a dynamo, it could work for ages.
