What does it take, out there in the field, to get an AfriGadget story?
Well, this video that I took back in the summer of 2007 shows Hash (aka WhiteAfrican) hard at work getting the Africa’s Modular Machines piece that went up in AfriGadget last November. Yes, the sound quality and camera work are atrocious but sometimes, opportunity just presents itself.
I am happy to report that as you can see, he was busy bringing Firefox to the people as he did this.
Over the weeks since the first post we did on Dr. Cedrick Ngalande’s inexpensive power source for Africa, we’ve been emailing back and forth about his invention. Yesterday, he sent me a link to a video of his device on YouTube.
“The rotor moves slowly most of the times but does pick up at certain intervals. This process continues for many hours. Since the rotor is quite heavy (and hence more inertia) a small geared DC motor can be connected to the rotor to generate power for cell phones, $100 laptops, and other things in Africa. People can leave this thing to charge their phones/$100 laptops overnight.”

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.

Victor Kaonga points us to Dr. Cedrick Ngalande, a Malawian, who has built a prototype power source made specifically for Africa. It generates power using sugar and yeast for up to 8 hours at a time.
Mobile phones are big in Africa, however it’s a real challenge to power them. How about night time electrical lighting, rather than paraffin lamps. Of course, in Africa we can think of all types of applications that this device could be used for.
This gadget will be very ideal to developing countries like Africa where electricity is scarce. As you know, the growth of cell phone is fastest in Africa. The problem most Africans have is that they cannot charge those cell phones due to lack of electricity. Some have to walk long distances just to charge cell phones. My invention will make it easy for these people to charge their cell phones. Also, this generator can be used to charge $100 computers which are being introduced in Africa. It can also be used to charge or operate medical devices in rural Africa.
On a side note, I love seeing inventions made by Africans for Africans. It’s only by living and being a part of the everyday life that you get past the surface issues and start to really understand the real problems to be overcome. Personally, I love this story; it’s ingenious and African – just what we like here on AfriGadget!
If you have any stories, pictures or videos of ingenious African solutions, send them to us!

There’s a really interesting story about a man in Kenya who claims to have created a plane from scratch.
Using a Volkswagen beetle engine, and aluminium sheets for the body, Mr Gachamba made a single seater plane.
He tested it out at an airstrip in Nyeri and sure enough, it took off. Caught up in the excitement of the minute, he decided to fly to his home in Mathira.
A few minutes into the ride, he noticed the engine was overheating. He decided to turn and in the process the low flying plane struck a tree top and crash landed. He was injured in the leg and has had a limp since.

I’d love to see pictures of this plane, though I’m doubtful of there being any as this happened in the 70’s. Either way, a fun story. Right now he’s building his own Hummer from an old Datsun engine and “wheelbarrows, wheelchairs, metal pipes and other vehicle accessories”. At 75 years old he’s not slowing down at all!
