The people pedal powered computer charger is a device that harvests human energy to charge a computer. The energy input comes from an ordinary bicycle in a stand that drives a generator. The energy output is the charging voltage of the computer.

Introduction
The project Vélo M2 plays with PPP (people pedal power) applications. In Brussels we're having PPP open-air cinéma projections, PPP mobile fablab workshops and PPP music scenes and DJ sets. [www.velom2.be www.velom2.be]
This projects takes the PPP to a smaller scale, where we will be charging a computer. In order to demonstrate the accessibility, we're construction the device in a remote town in Sweden, Torsby.

Étape 2 - Overview
Étape 3 - Charging : adapting to the computer voltage
The aim of the people pedal power is to charge a computer. A computer battery is normally charges by an adapter that converts AC mains power to DC power. This charger will be only for YOUR computer.
Be informed :
- we want to charge with the same power as the adapter does
Check the voltage and the current at which the adapter charges your computer. Mine charges at 20V and 4.5A.
- you will be cutting your power cable
You can also chose to buy the plug separately and assemble a new cable.
Étape 4 - Conversion : messy DC power to flat DC voltage
Étape 5 - Bicycle : human energy to mechanical energy
The fist etape is the conversion of the human energy to slow-rotating mechanical energy. We are using an ordinary bicycle to harvest the energy.
Think about this :
- your bike should have low-profile tires
When the profile is too important (see picture) there will be a large energy loss due to vibrations. You will also have more noise when pedaling.
- the fixation of the axis should be not of the fast-release type
The fast-release-type with flat end (se picture) is often not compatible with the bike stands. You can easily change the axle with another (second hand) axle.
Étape 6 - Bicycle stand :
Étape 7 - Roller : slow- to fast-rotation mechanical energy
The second etape is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.
Étape 8 - Generator : mechanical to electric energy
Étape 9 - Conversion : messy DC power to flat DC voltage
Étape 10 - Charging : adapting to the computer voltage
