On the outskirts of Maroua, the capital of the Extreme North of Cameroon, is a place quite unlike any other in the country. Here a community of les forgerons—blacksmiths, or metalworkers—practice their craft in the relative cool of a tree grove. Several dozen men with specialized skills are gathered here for a single purpose: to transform piles of scrap iron into finely finished tools, stoves, replacement parts and other useful implements for sale to the local population. Young apprentices learn the craft while operating bellows or shaping wood for tool handles. The production here is performed entirely by hand and on a scale which must be seen to be fully appreciated. ….

Looks barbaric but check out the results!

Made from brass and modelled on something much more professional, this manual tooth mould (I’m sure there’s a technical name for this gadget) is cheap and brings smiles back to faces.

Drogba at work

Drogba’s leather press is an assembly of diverse components.

The fly wheels are made up of two used conveyor pulleys full of concrete. These are joined together by two used second hand vehicle half shafts.

The half shafts are connected to an old bench vice screw (hope you are singing along here)

The screw is connected to a press foot

(all together now) “Oh hear the world of the lord” (tune of the kids song Dry Bones)

The print plates are placed on the base of the press frame.

God is able - so is Drogba!

When Drogba spins the fly wheels, he sandwiches the leather between the press plate and press foot producing perfect permanent imprints in the leather

This method is used for most of Kenya’s printed leather products, a huge industry that includes Maasai beaded belts, menu covers, wallets, passport holders, belts, key holders, coasters, handbags, purses, and many fashion accessories and leather souvenir products.

Drogba is 18 years old and works a good 12 hours per day on a casual wage. He has just completed high school and is looking for a college placement.  As you can imagine, he’s a huge fan of his soccer celebrity lookalike and namesake.

Catwalk ready arc welder

This bizarre fabricated arc welding machine is the unique collaboration between jua kali and mitumba. Jua kali literally means hot sun in Kiswahili, and refers to the informal small traders who work outdoors in the sun fabricating mostly work metal and wood items, fixing cars and other household items. Unable to afford new tools they fabricate their own out of locally available materials. Mitumba refers to the second hand western clothing sold on the streets of many African cities. The arc welder uses stolen scrap and second hand wires that are coated for insulation using strips of cloth torn from unsellable mitumba clothes.  This is then wound into the welding machine coils.

God help James if it rains!

I’d gone to Limuru to get a welder for a job on a dairy where I met James Mutahi. He is a typical jua kali wrought iron artisan who operates on the sidewalk outside his street workshop using his own home made tools.  I’ve seen jua kali home made arc welding machines before but usually they are housed in a protective box. To save money James dispensed with the casing revealing the guts of his arc welder.

James was making security grill for a window. There’s a huge demand for arc welding in Limuru especially for gates and window bars which are essential in the high risk security zones of Nairobi and other urban centers.  Nairobi’s security is the result of the collaboration between mitumba and jua kali!

The picture speaks volumes about the Jua-Kali sector in Kenya– cost saving is paramount whilst safety is overlooked hence no housing box – look for welding goggles, fire extinguisher and other safety gear.

Tractor tyre trough for water for goats and sheep

This old tractor or truck tyre was somehow cut, opened up and sealed at either end to make a perfectly good livestock watering trough. Even Joy Adamson noted that the Masai question using modern appliances if home made ones do the job anyway.

Tractor tyre cattle salt lick

Another way to make  a salt lick, Evelyn just cut a truck tyre in half and placed it  on the ground supported by stumps.

home made bucket works perfectly

Why buy a bucket when you can just make one with an old water container and a piece of metal?

Home made shovel

And if you don’t have a shovel for your manure, just straighten out some corrugated iron, cut it and nail to a stick  and Presto – probably more effective than anything you could  buy in Nairobi. Manure is one of the few products sold to passing trucks on these remote ranches.

Keeping land open for wildlife migrations in and out of Nairobi National Park can be costly to those living with wildlife. Those in The Wildilfe Foundations land lease scheme earn 4$ per  acre per year to keep the properties open (no fences)  and to supplement their income they make beautiful beaded artworks for sale on Olerai Conservancy.

It might look like a tough life for some of us, but the Masai out here seem perfectly satisfied and at peace

At the Karen market I met the charismatic Mohammed Makokha who proudly showed me two of his home made gadgets that are critical for his business.

I’ve obviously been wasting my money in the bicycle stores.

Here’s a short video with some footage of them at work:

One of my favorite stories on AfriGadget was the other unique bellows I found, this time in Nairobi, made out of an old bicycle. Both of these go examples go to show what can be done with very little. It’s about improvising what you have and overcoming a challenge.

Adam and Abdul make all types of items, but they told me that their main products are anchors, which range from small to large (2000-5000/= or $26-65) and, chisels and coconut shellers. They create a lot of the small metal pieces on the local dhows, and also make doors and window frames for the homes in the town. Really, they can make just about anything that you desire, like experienced metal workers anywhere in the world. What’s amazing is what they do it with.

IDDS Ghana 2009

The International Development Design Summit is put on by Amy Smith and her students at MIT. This year it took place in Kumasi, Ghana – which will be followed by Maker Faire Africa this weekend in Accra, where some of their work will be shown.

Here’s a quick list of the projects they have been working on over the last five weeks:

- A press that speeds up the process of extracting oil from shea nuts
- A device for generating electricity from a playground carousel
- A machine for making recycled plastic products from used water sachets
- A set of tools for threshing groundnuts
- A mechanism for producing chlorine from salt water using readily available materials
- A simple, low cost battery made from local materials, for household lighting and other uses
- A human powered grating machine for speeding up cassava processing
- A thresher to improve the quality of rice by preventing stones from mixing with the grains
- A chlorine dispenser for disinfecting drinking water
- A family friendly latrine designed to promote use and hygiene among young children
- A device for monitoring the growth of children under five through cell phone technology
- A container that extends the shelf life of tomatoes during transport and storage

Edward tells Hazwan some of his thoughts on the rice threshing machine.

The importance of being in Ghana

Niall Walsh has written this information about how the importance of the move to Ghana for this year’s IDDS was to both MIT and the participants:

The main difference between IDDS Ghana and IDDS in MIT is the proximity to community partners and potential end users of the projects. IDDS prides itself on the spirit of co-creation and this movement from the States to Africa is a crucial one in line with this vision. The difference between participants sitting in lecture halls in MIT, learning about international development and the importance of speaking to at least fifty villagers before designing a technology, and actually living with and talking to hundreds of villagers all over the country, is immeasurable. In total IDDS this year worked with ten villages throughout the Bromg – Ahafo and Ashanti regions and teams had the chance to make three separate two night visits (spread throughout the design process to make sure they had input into every stage) to these villages. Among a huge number of other factors, the simple experience of having end users actually become extremely excited about your prototype, and seeing them test it out, is an incentive for teams to continue their project after IDDS.

Another way in which IDDS interacted with the local community, rather than simply for it, was through it’s interactions with Suame Magazine. This is an engineering cluster located in the centre of Kumasi, spanning twenty miles and with a working population of over 200,000 people. There are approximately 12,000 independent micro, small and medium enterprises located in the area and their main activities of vehicle repair and metal fabrication (welding and casting) are renowned for their ingenuity all across West Africa. During the summit, participants worked extensively with these engineers and mechanics in the ‘Magazine’ and had the chance to share ideas, techniques, and technologies with each other

The point has been stressed home at this year’s IDDS that these villagers involved in the process, as well as the workshop guys in Suame, are partners in the design process, rather than simply people we should talk to along the way. Without these partners, the technologies presented tomorrow at the Great Hall would quite simply not be possible, and I think that knowledge, in and of itself, will prove invaluable to our participants as they continue to work in international development after the conference. In light of this, five villagers from each village, as well as workshop managers from Suame, will be provided transport, accommodation and food to come to the final presentations to see all the different prototypes.

Systems have also been put in place to ensure that the projects worked on at this year’s IDDS will continue to be worked on after IDDS. There are project grants and partnership grants available for the teams and there will also be a full time country liaison for Ghana, responsible for integrating the technologies into all of our partner villages, as well as sourcing new villagers and markets to help disseminate and create business models for the technologies. On a far more practical level, villagers will also have the opportunity to decide which of the prototypes they are most interested in, and then work with our partners in Suame Magazine to have these manufactured.

If you haven’t been to the Mara during the spectacular migration, then you might find it hard to imagine our frustration – try rousing 5 kids and 4 adults at 5 am, pack them and lunch and head off to the Mara River to witness for the first time in our lives, the crossing of thousands of wilderbeeste, zebra, gazelles, lions, – images of crocodiles leaping for the bleating calves … adrenaline racing with anticipation…..and then “poof”, a flat, right at the edge of the Mara reserve.

No big deal right – just change the tyre and continue. Five minutes delay? No, 3 hours later,  we’re screaming at the rental agent because the key for the spare tyre’s lock does not work! Aaarrrggghhhh

With second car we head to Talek hardly expecting to find an outfitter who can repair tubeless tyres.

This is what we found.

Finding punctures in a converted wheel barrow - there were 15!

A modified wheel barrow full of silty water and a bit of detergent to find the holes. We stopped counting a  15 – it was very depressing! I don’t even remember  going over a thorn bush either!Should have been my first warning – these tyres were seriously worn and thin.

The air compressor system comprised a tank and engine and a compressor unit – the last part was an adaptation from an airconditioning unit off a vehicle! Very creative.

Modified compressor

In the end we had to opt for converting a tubeless tyre into a tube tyre – and this is the gizmo that was used to remove the tyre. It was completely home made and very effective. We found an old inner tube with just about the right dimensions at one of the tented camps, 350 shillings and 3 hours later we were on the road again!

Once back on the road Mara never fails to impressWe witnessed the crossing

Wildebeeste crossing the Mara River

It was well worth the hell to get to the crossing point – and of course this is where we experienced puncture no. 2! Crazy place for a puncture as you aren’t allowed to step out of your car while animals are crossing. Hours later It was back to Talek jua kali puncture repair for us!

Yeah, the predators were in good form too

After 3 days of stunning experiences we headed back to Nairobi on what may easily be described as the worlds worst road. That was where the new tubed tyre went totally bezerk on us and exploded ripping the tube completely in half! Turns out the tyres were so worn that the wires in the tyre  simply ripped the tube open. Nice one!

We discovered that the spare lock could be opened with a good whack! with a tyre spanner and off the lock fell. Away we went.

Words of advice to anyone renting a 4×4 to go on a major trek to Mara or anywhere in Kenya – check everything  before you go, take rental company managers personal cell no with and make sure you have credit and full phone charge, take a second car if you can, and a fundi (without my brother I’d probably still be on the road side – thanks a million Dom!). Despite the annoying hassles of the rental car and the unbelievable road, the trip was well worth it. I refused to pay for the lost day and was so glad to see the back of that damn rental car – the agency didn’t quarrel.  Gonna buy my own safari car now.
