Joseph Omwoyo, a young Kenyan form-four student in Western Kenya, did just that and built his own version, using locally available materials. It doesn’t fly, nor does it look like it will ever take off – but what really matters is that a young boy with limited resources still had the energy to fulfill his dream:

“…Omwoyo says he got the idea while in Form One when he, together with his colleagues, toured the Kisumu Airport, and – during the short time there – the idea of making a chopper stuck to his mind”.

We’re sure that Kenya isn’t the only place where people are trying to build their own aircrafts, BUT! this certainly reminds us of the Kahawa West Aircraft story back in October 2010.

For Joseph, the helicopter may be his own escape from reality, or in his words: “Emargence Door Exit”. Touché!

Update: the original video has been removed by NTVKenya, so we can only hope it will be uploaded again in the next few days.

So… “what do you do with old billboard posters”, asks Kenyan bloggger Daudi “Mentalacrobatics” Were on his Posterous site – and instantly delivers the following snapshot:

“Apply Nairobi ingenuity and waterproof your house!”

Talking about reusable materials, here’s another popular reuse: a football / soccer ball made using old plastic bags, newspapers and sisal string. Demonstrated by the kids at The Nest Home, a children’s home in Limuru, Kenya:

It’s cheap, it works, it wins!

We actually prefer these creative toys as the kids learn how to MAKE things – instead of just buying cheap Chinese toys.

If you’re interested in “toys made from trash”, please also have a look at this wonderful website run by Indian toy inventor Arvind Gupta.

No less ingenious and fascinating are toys created by and for kids themselves, usually from the simplest of materials and tools. This includes items like toy tractors (Kenya) and SUVs (Uganda) made from recycled plastic bottles.

In Cameroon, one such popular toy crafted by kids is a ‘remote controlled’ car or ATV. These are often built from discarded flip-flops (slippers), sardine tins, bamboo or raffia palm, electrical conduit (pipe), rubber and bits of string. A variation on this theme that incorporates a split bamboo steering column and a full-sized wire steering wheel was blogged by Steve in the northwest of the country.

It’s not difficult to spot toy cars like this being piloted by kids in Cameroon—the trick is usually being able to catch up with them to photograph one. A big advantage of this design is its ability to handle rough terrain when being driven at speed. The bamboo frame, chunky tires and rubber fasteners suck up bumps in the road like a 4WD Toyota. The proud builder of this R/C all-terrain vehicle paused long enough to demonstrate his creation for me.

We believe that  biogas from cow dung holds huge promise for rural and urban areas as a cheap source of energy that can be turned into domestic use or even business anywhere in rural Kenya….eg. pasturizing milk, making yoghurt, running fridges, generators, hammer mills for grinding corn, cooking, baking, heating water, running machines… and reducing your carbon footprint.

I have recently become the latest guinea pig for Dominic Wanjihias experiments … and it has been quite a learning experience

Problem No. 1.The system needs to be cheap and mobile for communities who don’t own land or who move regularly (pastoralists)

Simply Logic flexi -bag for biogas - small, cheap and made of parts you can find in any hardware

Biogas system on a motorbike in Kenya

You may need a Dominic to help set it up

It can be dirty work - but don't let that discourage you...

After only 2 weeks it will have ballooned like this

After only 2 weeks the bag will have inflated with methane - beautiful biogas

Great party trick: The biogas will burn and amaze

Problem No. 2. The pressure is not enough to light a stove. Nothing ever works as you initially planned that’s why having a fundi like Dominic around to modify, adapt and rethink as you go along helps so much.

To create pressure Dominic got two tanks, and did some juakali pipe connections. One tank was placed above the other. The lower tank was filled with water. Long pipes and short pipes were put through the lids and specially made holes in the tanks …  It’s all about applying simple physics really…

You need a few tools - all available at tusky's or Nakumatt

Then using a pump ..(we’ll be using a modified bicycle pump next time) he was able to move the gas from the flexi bag to the lower tank and displace water to the upper tank. This water creates enough back pressure to get the stove to light.. that’s the theory … here is what happened.

A curious boda boda rider (motorbike taxi) called Victor volunteered to help… Rhoda watched in awe

Victor pumped... others set up the stove

“Houston we have a problem” …Ok, accidents are bound to happen…pressure pushed the pipe off  and Victor got soaked..just water though. The top tank fills with water as you pump biogas into the bottom tank, and the water drains back to the bottom tank as the gas is used

Course all this hard work was not for nothing – we had to make a cup of tea -

It took 15 minutes for the water to boil!

Yes we are very very proud that the system worked so Cheers! a well deserved cup of tea.

We estimate that it took about 1/4 to 1/2 of the gas in one blue tank to boil the kettle – that’s about 1/8th of a cubic meter – and the entire flexi bag contains about 5 cubic meters… which means we have about 10 hours of gas use…..and the stuff is being produced all the time (we had quite some wastage as we fooled around to get the system to work)

Well it all seemed to be going just fine when …pssssssttttt

Houston, we have another problem...we sprung a leak!

Nothing serious but we were losing a bit of gas through one of the lids (holes had been drilled through the  lids to insert pipes) …we  need to fix that before we build up any pressure in that tank.

If you are interested in biogas let us know! Leave a comment.

You know you’re in Mali when it’s too hot in the sun and come up with an electrified spit roast that will do the job for you.

As seen by our friend Mischel at campement Woloni in Sélingué, Mali. Thx!

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?

These are the kinds of stories and projects that you just can’t make up. We’ve written about Nigerian Mubarak Abdullahi’s home made helicopter a couple years ago from old car parts. It appears that 3 Somaliland men built a helicopter too, using scrap metal and an old van engine.

Much like the Nigerian one, there is no video footage of this one flying. It’s not easy to build a machine that looks and acts like a helicopter, but it’s a lot easier than making one that flies. It does take a lot of drive, thinking and skill to build even these models, but I won’t be truly impressed until I see a video of one taking off and landing.

“The trio, Mohamed Abdi Barkadle, Saed Abdi Jide and Abdi Farah Lidan said the purpose of their helicopter was to be used to fight fire in the city and surrounding area. They receive no major sponsors, financial nor material support from any one including the government, it is a three men vision and ingenuity.”

Now, the question is… Could we get the three (and the helicopter) to Maker Faire Africa in Nairobi this August?

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.
