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.

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.

Here is their home-brew VHF SWR meter:

Antennas

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

William Kamkwamba grew up as a farmer in Malawi, at the age of just 14, he had built his own wind generator.

During a drought his families fortunes collapsed and he spent his time in libraries reading and discovering about wind energy. He found components for his invention in a scrap  yard; a tractor fan, shock absorber, PVC pipes and a bicycle frame.

When his prototype was able to run four bulbs people arrived to charge their mobile phone. William has just appeared on TED  Global conference in Oxford this week to the conference to tell the audience how he did this.

Another inventor has already appeared on Afrigadjet and has just been discovered by the BBC. Pascal Katana, 22 who with Jeremiah Murimi, 24, has gone beyond fish and has invented a dynamo-powered “smart charger” to help people without electricity in rural areas to charge their cell phones. The system costs $4.50 and it takes an hour to fully charge a cell phone.

These two young men developed the idea during summer break. Wish I had so much energy in my holiday.  These guys should be at Maker Faire in Ghana this August.

Alfred Sirleaf is an analog blogger. He take runs the “Daily News”, a news hut by the side of a major road in the middle of Monrovia. He started it a number of years ago, stating that he wanted to get news into the hands of those who couldn’t afford newspapers, in the language that they could understand.

Alfred serves as a reminder to the rest of us, that simple is often better, just because it works. The lack of electricity never throws him off. The lack of funding means he’s creative in ways that he recruits people from around the city and country to report news to him. He uses his cell phone as the major point of connection between him and the 10,000 (he says) that read his blackboard daily.

Liberia’s Blackboard Blogger from WhiteAfrican on Vimeo.

Not all Liberians who read his news are literate, so he makes use of symbols. Whether it’s a UN or military helmet, a poster of a soccer player or a bottle of colored water to denote gas prices, he is determined to get the message out in any way that he can.

Advertising works here too. It’s $5 to be on the bottom level, $10 to be on the sideboard and $25 on the main section. He doesn’t get a lot of advertising, and but he manages to scrape by.

His plans for the future include decentralizing his work, this means opening up identical locations in other parts of Monrovia, and in a few of the larger cities around the country. I don’t put it past Alfred either, he’s a scrappy entrepreneur on a mission to bring information and news to ordinary Liberians. He’s succeeded thus far, and I would put my money on him growing it even further.

(note: title for this post stolen shamelessly from Rebecca’s Pocket. I also first posted this at WhiteAfrican, because I couldn’t decide if it was an AfriGadget story or not…)

She uses ordinary size D batteries that are readily available in the village to power radios and torches. She wraped five (5) batteries together, then removed the plug from the phone charger and attached the bare wires to the + and – terminals of the batteries.

Mrs. Muyonjo is a housewife in a remote village of Ivukula in Iganga district, Eastern Uganda. She had a bad experience with a local mobile phone charger, so decided to hack her own solution in response. Read the full story on the Women of Uganda Network’s site.

The system, that Mbetsa created by combining technology from projects that he has completed in the past, uses a combination of voice, DTMF and SMS text messages over cell-based phone service to carry codes and messages that allow control of some of a vehicles’ electrical systems including the ignition to manage vehicle activation and disabling remotely in real time.

Another feature of the system is the capacity to poll the vehicle owner by mobile phone for permission to start when the ignition is turned in real time as well as eavesdrop on conversation in the vehicle.

Mbetsa is now looking for funding to commercially develop his proof of concept and bring it to the market as reported on this video carried on the Kenya Television Network earlier this year.

AfriGadget was included in Time Magazine’s list of 50 best sites for 2008.

This is quite an honor especially in light of the fact that AfriGadget is run entirely by volunteers. Good news though, our posting frequency should go up shortly as we have a team in the field sourcing stories right now.

As a primer to all things AfriGadget, here are links to our Flickr Group and Grassroots Reporting Project as well as a list of some of our favorite/most popular stories.

One of the consistent themes of Jan’s message is that it in each country he visits there is a booming market of hackers and mobile phone mechanics who are doing all kinds of interesting things. They are taking the designs of the West and applying them to their lives, modifying them and making them work for their local needs. From Accra to Nairobi, there is always a “cell phone alley” for you to buy, repair or customize your mobile phone.

In a post titled, “Recycled, Upcycled: Remade” he tackles the question of whether it is possible to create a phone completely of recycled parts.

Of all the internal concepts I’ve followed this year this is one I keep returning to, not least because sustainability is a pressing issue in a billion+ products-per-year industry – but also because the team tackled a number of related weighty issues in what was a far reaching project. I hope that in due course more of their design thinking makes it into the public domain, not least to stimulate critical feedback from people like your good selves.

One of the more interesting innovations is the development of a dual SIM card hack so that users can access multiple carriers.

This product has two SIM card slots in a single phone – primarily to support price sensitive/prudent consumers who wish to optimise their call costs by maintaining SIM cards from two different phone operators. As in many countries – calls to a customer using a different Ghanaian operator cost slightly more than those on the same network.

There are many more examples of mobile phone use in Africa and the ingenious solutions that locals come up with for their particular situations on Jan’s blog. The last image that I want to show is of the Village Phone project (by Grameen Bank) happening in Uganda. Jan has taken an excellent picture and annotated it with the important facts about this project in a rural Uganda.

For more information about Jan, read this recent NY Times article about him, and of course subscribe to his blog, Future Perfect.
