Nokia: Bicycle Charger Kit for Mobiles

There was a major announcement today from Nokia about the release of cheap phones for the emerging markets, featuring dual sims and the ever useful LED flashlight. What is even more interesting is that with the launch of the phones, a bicycle charger kit. According to CNET Asia, the kit will be available by year’s end.

Rounding up the announcements today is the Bicycle Charger Kit, which comprises a charger, dynamo and phone holder. When docked to the latter with a 2mm charger jack, the electrical generator will produce energy to juice up the handset. According to Nokia, the dynamo starts charging when the speed of the bicycle reaches 6kmh and stops when it hits 50kmh. It matches the efficiency of a normal charger when the bike is traveling at 12kmh.

The bicycle charger kit will be useful to many people in Kenya and other emerging markets, its only a matter of time before it is repurposed to charge other devices like small radios. All in all the phones seem AfriGadgetty, what with their dual sims; perfect for markets where people have more than one carrier – thinking of Nigeria here, where its not uncommon to see someone with multiple phones because of varying network coverage/dependability + LED flashlights, it is clear that Nokia is making products that have utility for millions of people around Africa. Personally I can’t wait to try out the phones and mobile kits as soon as I can get my hands on them. Come to think of it, this is hardware localization, something that could go hand in hand with the software localization we are clamoring for in the African market.

Many thanks to my friend Cyrus for the heads up, I think he has just inspired me to blog again.

Genius strikes again: kids in village build radio from scrap parts


It is one thing to drool over the coming digital age in Africa just by studying the numbers, charts and info-graphics. It is a whole other experience to encounter the early signs of all of those numbers and projections in real life. An even bigger experience when you stumble upon genius in the making right in your back yard.

Remember these kids that built their own toys? Turns out creative genius runs in my family. (Must have skipped right over me, this gift. Le sigh.)

As I was leaving my mother’s house in Masindi after an all too brief visit, I stopped into the boys quarters to say bye to my little brother and two of my nephews. They were busy listening to the radio and I was wondering where the radio came from cause certainly my mother wouldn’t afford them such a luxury.

My jaw dropped and Afrigadget logos started spinning above my head in excitement all cartoon-style! After pestering my mother to get them a radio for the room they used as their club house to no avail. They decided to just embark on building one themselves.

So while on holiday from school, my brother Caleb, 12; my nephews Ronald, 15 and Jesse, 12 rounded up some scrap parts and built what you see above in about a day. I didn’t have enough time to interview them properly, but man was I smiling all the way to Kampala.

Mind you that this was done out of curiosity and not some educational endeavor. Can you imagine what else Africa’s kids could build given even a slight revamp of the education system? With nearly 50% of our population under the age of 15, just how many curious minds are just waiting for an opportunity to do something like this?

As an aside, you can’t tell me you would have thought to use a jerrican as a boombox! That’s just beyond mad genius. Anyone know of cheap engineering kits I could get them to continue to play?

Building a (one-stage) Anaerobic Digester

David of the Kenyan Community Initiative Support (KCIS) recently built a very low tech Anaerobic digester using only a drum, a valve and some pipes:

The balloon shows that gas is being produced. The costs for the drum and professional valves may already be too high for some, and the design isn’t that optimal. They intend to add a storage drum with a water-filled header tank for constant pressure and the loading & desludging processes obviously still require some work.

We still like the approach though, because it does indeed “prove the theory”, as David notes. The theory of building a rather small anaerobic digester that will even work with smaller amounts of organic waste.

Goes to show that producing methane gas from something which would otherwise remain unused (livestock faeces usually kept in such drums for a few weeks without harvesting the methane potential) still is an interesting alternative & well appreciated once costs are covered.

Boys toys in Mathare Valley Slum Nairobi

Amid the squalor in one of Kenya’s most depressing slums, there is a surprising amount of flashy colour and fun

Njuguna makes these toys because he like to! His clients are local people in the slum but he does sell well outside of that market too.

I was especially enthralled by this scrap metal motorbike but the price was Ksh 2,500 (US$ 30) which may have been a special price for visitors like me – I couldn’t afford it!

Scrap metal gocart – boys in heaven!

Njuguna also makes beautiful micro toys for a specialist corporate market – they had been sold but he had photos

You guessed it – client was Safaricom!

Amongst all the toys were some other serious gadgets that Njuguna had put together for no specific reason -a couple of free standing windmills rotate rapidly in the narrow streets that channel the wind. They stand there like artistic monuments, but Njuguna told me that he made these constructions made from parts taken from broken cars and had put them out and was waiting for an idea to strike him regarding what to apply them to. He called it his research experiment. …  somewhere else lay another of his inventions, a waterpump  …..(should I have suggested something?)

Kids play by open sewer in Mathare Valley

Visiting Kibera was disturbing in so many ways

,

….and yet it was thoroughly invigorating and inspiring – a pleasant surprise . If you ever get a chance, do visit and seek out the Njuguna’s tucked away in narrow streets. These brilliant artists and innovators might live in what seems like the worst hell on earth, yet somehow it feels like they choose to.
