We recently built two smoothie bike systems with large light-up advertising signs. These use our electrical pedal generators to charge some capacitors. This electrical energy is then used to power some standard electric smoothie machines. There is a large LED sign which lights up as you ‘fill’ the unit with energy and the, when the energy is used up, the lights switch off.[Read more…]
Here are some photos of our pedal powered fairy lights. This unit can take one or two pedal generators and powers strings of LED lights, 5m or more. The unit stores the energy from the cyclist in an ultra-capacitor and, when the capacitor is full, it runs the LED lights with a randomly chosen effect.
This included a two-day workshop for a number of bicycle related community groups to produce four pedal power generators, a one-day public pedal power workshop and a two and a half hour pedal powered screening of Metropolis at the Cube cinema. This was organised with the help of Sprockets and Dust.
