Open Energy Monitor

We want to know how much energy we produce when cycling. The open source tool of Open Energy Monitoring will help us visualizing the energy production and in extension the consumption. Our system now is build in the following way : - input : 18-34Vdc 8A, five times - buffer : supercapacitor 18-48Vdc - …


PPP computer charger

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. Find the instructions on WikiFab !

Capacitor An electronic component able to hold a charge. It can be used in the same function as batteries with the following differences : + a capacitor is easier to recycle than most batteries (references will follow). + a capacitor can provide and absorb a higher peak power. – the voltage varies with the charging …

Energy module

The energy module allows to treat the power form the PPP bike generators. It buffers the power to keep the supply-demand in balance and it converts the messy DC power to AC 230V power. The inverter we are using is a 24V 800VA Victron inverter.
