The Bamboo Bike project

The Bamboo Bike, an endeavour that aims at building bicycles in a sustainable fashion using bamboo as the primary construction material, is a joint project run by Craig Calfree of Calfree Design, a high tech bicycle design firm based in California and The Earth Institute at Columbia University.

The bicycle is the primary mode of transport in Africa and it is used for everything from personal transportation to moving medicine and the sick to hospital. Sadly, the design used in most of Africa has not changed for the last 40 years to take into account the different ways in which the bicycle is used. In fact, most bikes in use in most of Africa today are based on a colonial British design tailored to individuals travelling short distances on smooth roads.

While making bike frames based on bamboo is not a new idea, most bamboo frame designs simply use bamboo for construction material in a traditional bike frame design. Leveraging the unique properties of bamboo such as its strength and flexibility to meet the specific needs of populations local to various parts of Africa is one of the primary rationale behind the Bamboo Bike project.

The team working on the Bamboo Bike project in the US, Ghana and Kenya among other locations have a interesting blog (last updated in the summer of 2007) that chronicles the struggles of the project team while on site in Africa.

Project gear including Bamboo Bikes and clothing is available on the Bamboo Bike and Calfree Design websites.

AfriGadget Gets a New Look!

We’re proud to announce a brand new design for AfriGadget! The old design was rather old and ugly, so thanks for putting up with it for the last 20 months. Actually, I think the reason that there are so many more RSS subscribers to AfriGadget than daily visitors can be attributed to how it looked… 🙂

2 New Things:

You’ll notice two buttons just beneath the header. We’re working on a number of items, two of which we’re ready to unveil.

The AfriGadget Grassroots Reporting Project
We’re intent on getting more AfriGadget contributors from all over Africa. Part of that plan is to find potential editors and set them up with a mobile phone with which to take pictures and do interviews. If you know someone that would make a good fit, let me know.

The AfriGadget Store (phase 1)
The first phase of the store is making some AfriGadget gear (t-shirts and mugs) available to everyone (hint: you can customize any design and select any type of shirt/color to put it on). The next step is to create a full-featured store with some of the items that are made by the entrepreneurs shown on AfriGadget. This would include products, as well as plans.

One of the big goals here is to create a service that doesn’t just publish interesting stories about African micro-entrepreneurs, though we do plan on continuing that, but to also explore ways that we can be a conduit back to those very same people. This redesign already has our future plans for dealing with entrepreneurs built into it. Part of that is the future phases of the AfriGadget store, but we’re also looking at ways to partner with others and encourage direct investment into worthy entrepreneurs businesses.

Look for more on that in a future update. Until then, we’re just happy we have some new stuff to show you!

If you find any errors, which I’m sure there will be some, please leave a comment or shoot me an email.

Lastly, a special thanks goes out to Jared for making this site look so good.

Africa’s Modular machines Continued: Saws

This is a continuation of Erik’s post on African Modular machines.

The video below shows how the machines are used in wood workshops to make design cutouts, carve out pieces for furniture and to split planks of wood. It is essentially the same machine pieces, motor, pulleys and frame, just customized for different uses. The customization is done in a small industry locally known as Jua Kali or Gikomba, where entrepreneurs like Mr. John Chege purchase them for use in small workshops like this.

When playing the video, please mute it, there is lots of noise from the machines.

Africa’s Modular Machines

One of the things that I find most interesting in my travels around Africa is the similar uses of technology to meet the varied demands of different types of mechanics and workers. The particular case I’ve been thinking over is the use of a simple frame and different engines to meet a specific need.

Many of the same components are used from one machine to the next. The fabricators know that each machine has a different use, but that the parts used to make them unique are not that many.

For instance, below is an image of a painting machine.

The painting machine has an engine, an air compressor and a tank for holding the compressed air.

I’ve seen the same setup, switching out the air compressor for a circular saw, water pump, or a generator. In the same way, the compressed air tank can be switched out for a larger fuel-holding tank or some other machinery that fits the specific need.

Below is an image of the same type of machine, this one with the same setup, except that the compressor is used for tire repair instead of painting.

Generally, the engine and the frame are the mainstay. The engines used are primarily Briggs & Stratton, the old workhorses of Africa, though I’ve seen Honda trying to make headway in this market lately as well.

The machinery setup is a good example of low-cost fabrication using a modular setup. All of the local fabricators tend to use the same frame setup so that they can mix and match with each others work.

[Update: I’m currently going through my archive of pictures and videos for more machines like this. If you have some pictures of these types of machines, please send them my way.]

Mubarak Abdullahi’s home-made helicopter takes Nigeria’s Kano Plains by storm

Yahoo! News (among other sources) carries a story from October 21st about Mubarak Muhammad Abdullahi of the Kano Plains of Nigeria who has built a working helicopter over the last 8 months using scrap aluminum and parts from a Honda Civic, an old Toyota and from the remains of a crashed Boeing 747.

This inventor has had no formal training in flying and his helicopter has never flown higher than 7 feet of the ground. In an interview, he talks about how the machine works:

“You start it, allow it to run for a minute or two and you then shift the accelerator forward and the propeller on top begins to spin. The further you shift the accelerator the faster it goes and once you reach 300 rmp you press the joystick and it takes off,”

Mubarak is ambitious however and has embarked on a new project to build a better helicopter that will be able to make 3 hour flights. He hopes to get support for his project from the Nigeria Civil Aviation Authority (NCAA) and other Nigerian government bodies.
