Katharine Houreld has filed an AP story describing how the Ol Pejeta Conservancy, a private game reserve ranch in Kenya and Save the Elephants, an NGO dedicated to the survival of the species are using the combination of a GSM/GPS based home brew animal collar solution to track and monitor movements of elephants and other animals.

A pilot project placed an electonic collar containing GPS and GSM units on Kimani, a bull elephant who was the last surviving member of a 5 elephant group with a penchant for raiding farms to eat crops. This collar allowed park rangers to track the elephant’s movements using Google Earth / Google Maps. The project also allowed park authorities to monitor animal locations at all times and acted as a deterrent against the poaching of this important resource.

Crop raiding is a huge problem on farms bordering parks and reserves as a herd of elephants or other animals can wipe out entire crops on a single night destroying the livelihoods of the farm owners.

The coolest side benefit of the product though was when the project team figured out that they could create a virtual “geo-fence” and trigger alerts whenever Kimani the elephant stepped outside this virtual fence - an occurrence that indicated that he was probably on his way to a village to carry out some crop raiding.

The set up used a hardware and software solution that sends text based messages in real time with location data over GSM to park rangers whenever Kimani approaches a park fence that is close to a farm.

This is yet another great example of why the use of mobile phones continue to be the computing platform of choice in many ingenious and innovative homebrew technology solutions in Africa.

Morris Mbetsa, an 18 year old self-taught inventor with no formal electronics training from the coastal tourist town of Mombasa on the Indian Ocean in Kenya, has invented the “Block & Track”, a mobile phone-based anti-theft device and vehicle tracking system.

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.

We just received some great news.

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.

• AfriGadget Innovator Series: Simon Mwacharo of Craftskills
• The amazing story of William Kakwamba and his home made windmill. William later went on to tell his story at TED and has embarked on even more ambitious projects that you can read about on his blog

I recently had a chance to conduct an email interview with Simon Mwacharo, an entrepreneur based in Nairobi, Kenya who a great example of what George Ayitteh has so aptly described as “The Cheetah Generation”.

Simon owns and runs CraftSkills, a small business based in Nairobi, Kenya that focuses on designing and building self-sustaining renewable energy projects in places not accessible to the electric grid. Craftskills had to date undertaken challenging projects in Kenya, Uganda, Tanzania, Cameroon and Rwanda among other places. Simon, whom AfriGadget first got to meet last summer at TED Global in Arusha, Tanzania, graciously agreed to conduct an email interview with AfriGadget.

AfriGadget: Could you tell us when and how Craft Skills got into the business of renewable energy in East Africa and the inspiration behind the organization?

Simon: CRAFTSKILLS was found in the year 2000 by myself. I was inspired by a challenge from my rural home where we have not had power for the last 40 plus years since [Kenya's] independence [in 1963]. I come from a hill side village in Sagalla, Taita Hills in Coast Province where we receive quite some strong wind from the Nyika Plateau. This wind passes through without being tapped and sometimes our roofs can not stand in its way.

I started talking to people about wind turbines and how I can get an affordable one which I can make and produce for other needy people. When darkness falls in these villages plus the fog it is virtually impossible to travel the terrain at night.

AfriGadget: Tell us a little about the people behind Craft Skills and the staff who work for the organization.

Simon: I started with two workers. I could not afford to hire trained people so I decided to train myself first then train my two boys. Then I got a friend who repairs radios and TVs in Kibera to help me design and put together a charge controller.

Now we have a team of 20 people and other partners out there in the field with their staff totaling 50. We have technicians, welders fitters, fiberglass experts and engineers and sales people.

AfriGadget: What is the typical profile of a Craft Skills project? Who is your typical client and how are the projects typically executed?

Simon: Most of our clients are not the owners of the projects we put up. They benefit from the battery charging services in the wind/solar sites we put up with our partners. The low income earners who cannot afford grid power or are in settlements where grid power is unavailable. We take both to do the sites ourselves involving the people on the ground as partners. Others are home owners who have invested a lot on building good homes in non grid areas – these put up turbines for their own use like lighting, and pumping water from wells and boreholes. The other segment is the business people I market areas where there is no grid who put up turbines to run charging centres and sell power to other shops or run their off-grid businesses like lodges and hotels, schools and other institutions.

AfriGadget: Can you share with our readers some of the challenges that Craft Skills faces in executing your projects?

Simon: We have faced cultural challenges where we cannot put a turbine on the most ideal site due to beliefs on such sites hence we have to educate the citizens to allow us to do so or redesign the project and relocate. Another is the financial capability of the citizens we find in these off grid areas.

[As a result of this] we have designed low power product (battery bundles and LED lights) to reach them so that they can be counted as beneficiaries of this new technology.

AfriGadget: Why renewable energy? What is the rationale behind Craft Skills’ exclusive focus on projects that produce energy from renewable sources.

Simon: We were looking for something which is affordable and sustainable and cuts across the economic sectors. Solar was proving to be more expensive, delicate, sophisticated and easily stolen when installed on ones home. We needed to sell people more power at a cheaper rate hence wind was the best candidate.

Wind is everywhere just like solar – one needs to get the right spot to put the turbine as high as they can. Its 24 hrs (Day and Night) and we found a cheap way we could make our turbines take advantage of low wind situations with the multi-pole generator, hollow blades for the propeller, with 90 per cent locally available materials making our technology the best application for this region.

AfriGadget: Which would you say has been the most satisfying/gratifying project that you have been involved with at Craft Skills? What was so special to you about this particular project?

Simon: The Chifiri water pan project to me is most gratifying. This settlement is all arid land pastoral community. The demand for water for drinking washing and watering the thousands of livestock is enormous.

Our turbine provided a cheaper solution for water and lighting the “manyattas” around the water pan. The contractor on the ground is excellent on his construction of the earth dams. His design impressed me that water was going to be available for over 6 months instead of the normal 4 months after the rainy seasons. He made sure the dams were well compacted and fenced to avoid animals hoofing inside the dam – increasing the rate of percolation and lose of water in the ground. Water is only available at the kiosks which are piped and placed near the settlements. The project provides water troughs for the animals to drink from and bathrooms for the people to clean themselves in. Within the fenced dam there is an armed home guard or caretaker manning the place with a security light up the tower hoisting the turbine.

Simon was also interviewed by Juliana Chebet aka AfroMusing, a Senior Editor at AfriGadget on CraftSkills. You can find the video at this link.

What does it take, out there in the field, to get an AfriGadget story?

Well, this video that I took back in the summer of 2007 shows Hash (aka WhiteAfrican) hard at work getting the Africa’s Modular Machines piece that went up in AfriGadget last November. Yes, the sound quality and camera work are atrocious but sometimes, opportunity just presents itself.

I am happy to report that as you can see, he was busy bringing Firefox to the people as he did this.

The Bamboo Bike, an endeavour that aims at building bicycles in a sustainable fashion using bamboo as the primary construction material, is a joint project run by Craig Calfree of Calfree Design, a high tech bicycle design firm based in California and The Earth Institute at Columbia University.

The bicycle is the primary mode of transport in Africa and it is used for everything from personal transportation to moving medicine and the sick to hospital. Sadly, the design used in most of Africa has not changed for the last 40 years to take into account the different ways in which the bicycle is used. In fact, most bikes in use in most of Africa today are based on a colonial British design tailored to individuals travelling short distances on smooth roads.

While making bike frames based on bamboo is not a new idea, most bamboo frame designs simply use bamboo for construction material in a traditional bike frame design. Leveraging the unique properties of bamboo such as its strength and flexibility to meet the specific needs of populations local to various parts of Africa is one of the primary rationale behind the Bamboo Bike project.

The team working on the Bamboo Bike project in the US, Ghana and Kenya among other locations have a interesting blog (last updated in the summer of 2007) that chronicles the struggles of the project team while on site in Africa.

Project gear including Bamboo Bikes and clothing is available on the Bamboo Bike and Calfree Design websites.

Yahoo! News (among other sources) carries a story from October 21st about Mubarak Muhammad Abdullahi of the Kano Plains of Nigeria who has built a working helicopter over the last 8 months using scrap aluminum and parts from a Honda Civic, an old Toyota and from the remains of a crashed Boeing 747.

This inventor has had no formal training in flying and his helicopter has never flown higher than 7 feet of the ground. In an interview, he talks about how the machine works:

“You start it, allow it to run for a minute or two and you then shift the accelerator forward and the propeller on top begins to spin. The further you shift the accelerator the faster it goes and once you reach 300 rmp you press the joystick and it takes off,”

Mubarak is ambitious however and has embarked on a new project to build a better helicopter that will be able to make 3 hour flights. He hopes to get support for his project from the Nigeria Civil Aviation Authority (NCAA) and other Nigerian government bodies.

Peter Kahugu of Banana Hill just outside Nairobi makes a living using his bicycle.

And no, he is not a professional cyclist.

AfriGadget reporter Afromusing and I had an opportunity to interview Peter who has modified his bicycle with a belt, a set of tensioning pulleys and a grinding stone to make it a knife-sharpening machine. By kicking the bike up onto its stand and engaging a gearing system, he is able to use “leg-horsepower” to drive a grinding wheel and sharpen knives while “on the move”.

Peter has been at this for 2 years now and he makes about Kshs 500 ( app. 10 US$) a day by riding his mobile workshop from client to client sharpening all their knives as he goes. The grinding stone he uses has lasted an astounding 2 years and he has had to replace his drive belt a couple of times but that is as simple as cutting up a long strip of rubber from an old car or bicycle tire inner tube.

Be sure to click though on the image for video on YouTube of the Peter and his bike in action.

An all-in-one cooker, energy generator and fridge could soon be improving quality of life in developing countries, thanks to an international project launched this week.

According to a press release by Paul Riley, SCORE Project Director, the £2m Stove for Cooking, Refrigeration and Electricity (SCORE) project aims to work with rural communities in Africa and Asia, where access to power is limited, to develop a versatile domestic appliance powered by biomass that will significantly improve health and welfare.

The SCORE device, which is still in the concept stage and is shown in the picture below, will work through the conversion of biomass to sound energy for heating and cooling.

This technology is far more efficient and less polluting than burning wood in an open fire, currently the primary cooking method of two billion people around the world. Dr Pullen(Research team leader) adds:
“Using this technology while ensuring that the device is relatively low-cost and can be produced using local materials and labour is one of the great challenges of this project. Thermoacoustic systems have always been expensive and high-tech - a great deal of the first stage of this project will be taken up with translating the technology into something that can easily be mass produced.”

The MultiMachine Group at Yahoo! Groups carries plans for “The Multi-Machine” which is

an accurate all-purpose machine tool that can be built by a semi-skilled mechanic with just common hand tools.

Multi-machines are 3 in 1 machines based on old car engine blocks (a 3-in-1 machine is usually a combination of a metal lathe, mill and drill press). The machines are designed such that they use the tolerances and engineering initially used to create the engine block that is re-purposed as the core of the tool to help guarantee that various components of the machine integrate with a high level of precision.

The machines have a design that not only allows them to be assembled using “elbow grease” but that also allow them to run on alternative power sources where mains electricity is not available. They are also easily adaptable to new purposes by adding on modules.

Plans to build a multi-machine can be found at this link at the The Open Source Machine website.
