The Kinshasa stove

After all these fascinating AfriGadgets from Maker Faire Africa, here’s another invention as seen by our friend Cedric Kalonji, a Congolese journalist in Kinshasa (D.R.C.):

For the lack of a cheap power supply in the City of Kinshasa, smart mechanics came up with this little stove that speeds up combustion by adding a little electric fan (hidden inside this tube that looks like being part of a flat spring). The fan itself is powered by (Chinese!) batteries and with the burning of charcoal, this quick stove obviously isn’t the greenest solution. But it works and does the job for those who will otherwise have no alternative.

Cedric also mentions on his blog post that it’s difficult to identify the inventor of this device. A perfect example of how low-cost technology easily gets adopted and/or modified (and why intellectual property rights are still a major issue in many places).

Hacking the FLAP Bag!

This is part of an ongoing series of posts on the FLAP bag project, a collaborative effort by Timbuk2, Portable Light and Pop!Tech. We at AfriGadget are helping to field-test these bags that have solar power and lighting on them, and get interviews of the individuals using them.

I was a little concerned when 5 of the 10 FLAP bags that I received before I left for Africa weren’t assembled – just fabric, thread and electronic components. It would mean that I’d have to find tailors in each country to put them together. However, it turned out that one of my favorite parts of getting the FLAP bags to Africa has been working with the tailors.

What I end up doing is explaining the bag and how it works, then showing them the one that isn’t put together and asking them if they would be willing to duplicate. If so, they can keep the bag. Then, I offer a challenge, taking the two-paneled Portable Light Kits from KVA, I then ask them if they could make something from their own materials, with their own designs, from it.

They had 2-3 days to come up with an idea, pick the fabric and create the bag. I then bought it from them for $20.

It should be noted that the gentlemen working on these had very little time to come up with their ideas and then implement them, as I was very much on the move. The local cloth use in Ghana was amazing, and I only wish the Kinte cloth (orange) one was done with real Kinte cloth instead of a print. The Kenyans used more ordinary fabric, but they were ingenious with the details around use, size and practicalities around security.

To really see the creativity at play in the Kenya bags, you have to either see them in person, or a video. Since I don’t have the bandwidth for a video now, that will have to come later.

Jericho Market is a small market tucked away behind the industrial area in Nairobi, Kenya – near to Buruburu. It’s where you can find a lot of artisans who work on cloth-based projects, from clothes to bags and everything in between. I took off with David Ngigi, a local videographer friend of mine, to see who we could find. I brought two of the unstitched bags, two Portable Light kits and one completed bag as a sample.

The first person we spent time with was Joseph Muteti, a soft-spoken, 18-year veteran of the tailor trade in Nairobi. He specializes in making school bags for children and messenger-type bags. His bags are generally sturdy, with an added flair of embroidery to set them off for his customers.

Next up was Stephen Omollo, an energetic young designer who works on textiles ranging from shirts to bags. Style and usability are both important to Stephen, and his primary desire is to create items that people are proud to wear.

Interestingly, both Stephen and Joseph thought the bags were too large. Stephen wanted to cut in half, and Joseph by about a third.

Giving the FLAP bag to some electricians

Hayford Bempong and David Celestin are electricians at Accra Polytechnic, who I wrote about last as they had fabricated an FM radio station from scratch and used it at Maker Faire Africa. Hayford and David seemed like just the type to take a look at the bag and really determine its use. Being college-level students, they have a different type of lifestyle than many, and that might mean more ideas and thoughts about what the FLAP bag could be used for.

True to form, they were not nearly as excited about the quality of the stitching, or the textiles used, but very interested in the internal electrical components. They were excited about the idea of a bag with an in-built solar panel, and were curious as to wattage and the ability use step-ups and inverters to make it even more useful.

One suggestion that they made was around durability of the electrical components, specifically they suggested that a metal box should be built around it. Life in Africa can be quite rough on gear, and the chance that someone will sit on, drop, or crush this part is quite high.

A Locally Fabricated Radio Station at MFA

Locally fabricated radio station: Ghana 101.7 FM

I’m a sucker for radios and antennas, and was just so excited to see the guys from Accra Polytechnic at Maker Faire Africa. Hayford Bempong, David Celestin and Michael Amankwanor are three members of the National Society of Black Engineers who have created a full radio with their own funds and brains.

They showed up at the event and setup the local Maker Faire Africa radio station, running at 101.7 FM. In conjunction with the speakers that they setup for the close proximity announcements, the radio was used to transmit up to a couple thousand meters away and spread the word about upcoming activities.

Basic electronics

David Celestin has been building power inverters and other electronic devices from scratch since he was a teenager. Below is one of his first power inverters, that still works, and which runs out of a little box. You can tell it is all fabricated from scraps and locally available materials.

Antennas

The team also creates their own antennas from scratch, including the “slim jim” below, “ground plane and a circular antenna.
