Maina, Rhoda and little Winnie are  a typical Kenyan family who live on the outskirts of Nairobi in an area that has no electricity.

But they have solved the problem of getting the daily news

When I visited their home I was impressed that despite the lack of electricity, Maina has come up with an innovative solution and is able to keep up with whats going on and listen to his favourite Kikuyu music all day long!

Here’s a better look at the system – a second hand car battery hooked up directly to his radio

The wiring is simple

Fully charged the battery last 2 weeks. To recharge Maina has to take it to a place in town for 24 hours at a cost of Ksh 50 (about 80 cents US. If he were to  use ordinary batteries Maina would be paying several hundreds of shillings per month (15$) and creating toxic waste with their disposal (Kenya has no battery disposal system).  No wonder used batteries are in such huge demand!

And no wonder this family is smiling!

I’m wondering how much it would cost to hook up Mainas battery to a solar panel and  some lights. They currently depend on hurricane lamps.  Powered with kerosene these are not only a weak source of light but are dangerous and prone to cause fires.

Got any ideas anyone – can we charge a car battery from solar?

Post note:  This story was found while making a video slideshow about this average Kenyan families carbon footprint for WildlifeDirect.

It’s no secret that Kenya’s rivers are running dry as a result of forest destruction and environmental degradation which has led to a season of blackouts in the capital city Nairobi.

Typical of the ingenious people of Nairobi one street vendor has cashed in on the crisis with this wonderful gadget which he markets as

“Perfect for Nairobi black out”

As you can see I could actually read by the light of this lamp which is made from a used tin can, some pieces of wire to make the connections

And the battery compartment is ingeniously crafted from a circle cut from a retired flip flop.

I love my juakali lamp and everyone that I know  in Nairobi needs one of these lamps. Everything about it is so true to the juakali spirit – hand crafted using colourful recycled tins, and designed for a real purpose with a handle so you can move it around from room to room or hang it up. The vendor tried to sell it to me for Ksh 350 but we settled on Ksh 200 (about $2.50) though I’m sure he would have gone cheaper but the traffic was moving and I had to go.

If you want one visit the Nyayo stadium roundabout.  They stood out amongst the chinese junk that vendors are selling you could practically kit out your house from the junk on sale there. Here’s a short list of what I saw during my 30 minute traffic hold up:

Pens, hats, footballs, blow up spiderman (who needs one of these?), peanuts wrapped in newspaper cones,

smelly car things, driveres licence holding cases, scarves, giant maps, Kenya flags, apples, kits (spiderman kites),

Nike shorts, cowboy hats, socks, oanges, backpacks, cheap watches, key chains knives, olympic medals (yes I wanted one of those!),

knee length shorts for guys who sag, hazard ttriangles, cables to cack your car, name tags for meetings, torches, window wipers (!),

car mats, pears, plumbs, tiny folding chairs for children (or Chinese people?), vehicle number plates, fire extinguishers, stickers,

Enormous framed pictures of furry cats and snow leopards (I can just see one of these this in my house), bananas and bandanas, plastic lunch boxes, pillows and cussions, a huge variety of stuffed toys,

posters with Jesus’ sayings, polo shirts, stearing wheel covers, spanners, screw drivers and of course my favourite – juakali lamps.

Nairobi never fails to impress. I love it. What else have you seen on sale in the Nairobi streets?

If you’ve been reading AfriGadget for a while, you know of a name that keeps popping up over and over – William Kamkwamba. He was first written about by another blogger friend Mike McKay and then subsequently covered here on AfriGadget a good 3 years ago. His windmills and the story behind it are an inspiration for many. There is now a book, a documentary and a foundation all set up around the inspired story of windmills from Malawi.

Win a copy of “The Boy Who Harnessed the Wind”

As luck would have it, I have 2 extra copies of William’s new book. I’d like to share that with you, the readers of the blog. To do that, I want to challenge you to send in an AfriGadget-like story, picture or video. Just write it and attach the pictures in an email to main@afrigadget.com. I’ll review them and pick the ones that I think best fits the blog. It’ll be posted here with attribution to you.

We’ve got two weeks until Oct 31, so I’ll give one book away each week. Let’s see what you’ve got! And, yes, I’ll mail the book anywhere in the world.

Note: the best AfriGadget stories come with pictures, so make sure you send those in as well.

William in the news

He’s been doing his book tour in the US this month, hitting some pretty big shows, including ABCs Good Morning America and the Daily Show with John Stewart (videos below).

Football Made in Africa is a site put together by a Belgian outfit called Take Five that will air 50 shows that are 1m30s each. It’s a push for themselves and their content before the 2010 Football World Cup taking place in South Africa next year. It’s extremely well done, but that’s not why I’m writing about it here on AfriGadget.

Ever wonder how those plastic bag footballs are made?

Here’s how to use a condom to create a football bladder.

This is a proposed way to maximize the usage and efficiency of the KVA Flexible Solar Portable Kit by Dominic Wanjihia. Dominic was awarded one of the Flex Kits at the recent Maker Africa Faire in Accra after showing off some amazing new ideas.

One of the cheapest form of transport in Kenya is the “Boda Boda” literally meaning “Border-to-border”, a bicycle ride from one countries boarder immigration offices through no-mans land to the immigration offices of the bordering country customs office.

This mode of transport is non discriminatory and is used by people of all walks of life. from school children, market goers, workers, business persons, etc. The popularity is partially due to the speed and convenience as one does not get stuck in traffic. In the Lake basin town of Kisumu there are estimated to be over 500,000 BodaBoda’s. In the whole county, in excess of 1,500,000

The BodaBoda rider normally works from as early as 4.30a.m. to as late as 10.00p.m. depending on security in the area. He relies greatly on his mobile phone for clients to call for his services. His peak cycling times are early morning, lunch hour and dusk as persons head home from school and work. Translates to 4 – 5 hours in total daily riding time.

Due to the lack of know how and the complexity of electronics, the lack of power storage (i.e. a battery, and the cost) the Cycle dynamo is only effective for charging items and lighting while he is riding. Also, due to space or lack of, cost, insecurity and theft, attaching “Hard” Solar panels to the bikes has never been a viable sustainable option.

However, with the introduction of the Flexible Panels I believe wearing the panels on his back eliminates all these constraints. It also means he is generating power from sun-up to sun-down, an average of 12 hours a day.

Attaching the flexible panels on his back ensures:

1. His phone is always charged guaranteeing customer accessibility
2. He has light at home from the LED’s so saves on heavy power bills
3. He always has an emergency light with his – LED
4. The panels will not get stolen
5. One can also offer charging facilities to client being carried

Other users
The BodaBoda is not the only potential user of the Flexible Panel by wearing it. Anyone spending long hour’s outdoors is a candidate. The farmer, fisherman, hawker’s and peddlers, city council outdoor workers, tourists, campers and hikers – just to mention a few.

Attaching the Panel
It can be attached in a variety of ways. Velcro, Pop Buttons or simply attach Rucksack like straps so it can be worn with any garment. In the latter case the small pouch containing the controller and battery is attached to the back of the panels with Velcro.

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.

Kenya Bags

Ghana Bags

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.

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.

Electrical Students in Ghana take on the FLAP bag from WhiteAfrican on Vimeo.

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.

This is a corn planter. It costs approximately $10 (15 Cedis) to make, and it significantly decreases the time that it would normally take to plant corn. This invention came about by taking a look a medical pill dispensing devices and transferring that knowledge to his communities needs.

Shamsudeen (“Sham”) Napara lives in the norther part of Ghana, which is a lot more rural and isolated than the southern part of the country where you find Accra, or the central part, where you find Kumasi. He has a metal fabrication shop where he builds tools, mostly for agricultural needs of those in the surrounding areas.

He was at Maker Faire Africa this weekend and I was completely amazed at both the ingenuity and the quality of his work.

Shea Nut Roaster

That’s not all that Sham has been up to though, in fact, he’s been busy with a couple other projects. Specifically, he’s been working with Amy Herman from the Univesity of Indiana to figure out how to enhance traditional processes familiar to those in Norther Ghana. This means he does a lot with Shea nuts and the processing of them. It is one of the few fields dominated by the women in the community, and a lucrative business, since the processing from raw to refined can net a good margin of profit.

Below is a shea nut roaster – a small version, since the large ones are the size of a table. It costs around $40 (60 Cedi), and it decreases the time and energy normally expended in the work of getting the nuts ready for processing.

Soap Cutter

Though he has many more inventions in his workshop in Northern Ghana, the last of the three items that he brought to Accra was a soap cutter. It’s a device that has a hinge on one end that opens and closes with piano wires and guitar screws to hold wire tight across the device. As it is closed, it slices the soap cleanly.
