bike powered cinema

I recently got a commision from Hackney City Farm to build them a bike powered cinema. It’s more a bike powered DVD player with an LCD screen, but what the heck.

I’m still working out the electronics side; I’ve got questions about battery size and power measurement. I’ve got version 1 software working though, with a test rig to show me power status and automation control (DVD and LCD).
