Cyclokino

What?

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

Analog side:

• bike wheel rotation on DC motor

• generates 12V to charge batteries

• measure w/ voltage divider (50K & 100K) => 5V max...

Digital side:

• ...ADC (in microcontroller) => USB serial

• python => mplayer

• variable speed video !

Explanation of the system

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.

Made in Paris - 2013
