This is an interactive and cyclo-powered mobile cinema. It is developed as a part of the CarAmazAndes project:
The current code controls the speed of a video with the speed of a bike, check out the demo.Concept
- bike wheel rotation on DC motor
- generates 12V to charge batteries
- measure w/ voltage divider (50K & 100K) => 5V max...
- ...ADC (in microcontroller) => USB serial
- python => mplayer
- variable speed video !
We use a DC motor (like a dynamo) to charge a battery in order to be electrically independent.
To measure the generated voltage, we currently use an Arduino compatible board called Teensy.
This board sends the measures to a python program running in linux/mac.
This python program plays a video (using mplayer) at a speed that depends on the measures.
