Home-Trainer-Bike "no pain no gain" video system
i want to build a home trainer which connects to my computer in that way, that video will only be played when i do some exercise.
- attach bike dynamo to home trainer bike
- make connection to old external computer keyboard
- fiddle with the software so video is played when a button is "pressed" (or activated by exercise), if the button is not pressed, the video will pause.
the last point seems to be really tricky - any ideas?
any alternative ideas from anyone? i do not want some on/off switch because then you could simply do two strokes on the bike and sit back and relax to watch the movie. i want a solution where only when straddling the video will play.
