A year or so ago I was asked to build a pedal powered generator and pedal powered smoothie machine for London Bike Hub. Recently they asked me to build another smoothie bike for their events promoting cycling in London and beyond. This time I thought I’d take a few photos of it before I deliver it.
If you would like to build your own, I have created an instructable with details of making your own smoothie bike. My new version is a bit different as I now have access to a metal lathe.
If you would like to hire a pedal powered sound system or smoothie bike in the London area then drop London Bike Hub a line. Read on to see some photos of their new smoothie machine…
Re-innovation was asked by Magnificent Revolution to help build an 8-bike pedal powered generator for use over in Australia. Greer Allen has started up Magnificent Revolution Australia and has been working with Magnificent Revolution in London. She will be taking the generator over to Australia for a cinema event in Sydney.
She came up to Nottingham to build the main power equipment and wire it all up and test it. We had a fun week crimping, drilling and waiting for packages to arrive. She kept a great blog with photos here. [Read more…]
I have been working with Magnificent Revolution for a couple of years now. They do all things pedal power related such as pedal powered sound systems, stages for festivals and cinemas. They also do loads of pedal power workshops (build your own!) and educational events. I have been working on an LED power and energy display for them (check this blog post). We got to try it out round a month or so ago at the Portobello Road Pop-Up cinema. Here is a video of the set-up process of their 20-bike generator system. The funny green thing under the screen is the power display.
The cinema was part of the In-Transit festival 2011. There are more photos (by Paul Bence) of the event and the people here.
Renewable energy innovation has an active program of renewable energy promotion. We have a number of pedal generators and solar PV system which can be used to interactively engage the public, helping to explain the concepts of power and energy and promote renewable energy sources and energy efficiency.
We created our pedal powered water cannons to do exactly that. Use water cannons to knock down environmentally themed targets with an upbeat soul soundtrack – all powered by human pedal power. We were asked to exhibit at Nottingham Carnival of Cycling, a Sustrans event to promote cycling in all its forms. Loads of activities and demonstrations were provided and we promoted pedal power alongside Junk4Funk, who helped keep the beat with recycled musical instruments.
We set up a pedal powered smoothie stall at Tollerton Village Fete, just south of Nottingham. Using just pedal power to arrive at the event, we set up a pedal powered water fountain and bubble machine for younger children to ride and our pedal powered smoothie machine to provide fruit-based refreshment. The weather was good to us, the turn out was great and people young and old were having a good time.
Pedal power is a great, inter-active demonstration of power generation and consumption. Building your own pedal generator is also an amazing learning experience. There are a number of plans and designs around for the generator and stand (check out our own here), but information about the electrical systems is usually lacking.
Here is a full design for a shunt regulator for pedal power systems. A PCB, kit of parts and a fully built circuit will be available.
A pedal powered blender for making smoothies at festivals and events had always seemed like a great idea. It brings in a number of concepts: firstly there is the ‘we don’t need electricity for everything’ idea, secondly it helps to demonstrate the concept of power in a interesting and practical way, thirdly it helps to promote cycling and lastly it helps to get people to eat more fresh fruit.
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.
