Mon. June 4th: Visit to a Twende, a Tanzanian Innovation Center

Twende (Link)

Tembe is a Swahili word meaning Let's go!, and Twende is a social innovation center and non-profit organization in Arusha, Tanzania. Their motto is We empower people to design and make their own technologies to solve community challenges. We Make, We Teach, We Support.

I found Twende by googling maker space Tanzania. There are not many Do It Yourself (DIY) places in Africa, but I found Twende in Arusha. Since Kim and I were going to be in Arusha three days before the students, I contacted them for a visit. There were some difficulties meeting up, but Frank picked us up for the visit around 3 PM.

The Leadership

We met Deborah Tien, the Executive Director, when we got to Twende. She is an American with a degree in astrophysics from Wellesley College, and has worked in Nicaragua and Tanzania developing design strategies and appropriate technology for less developed countries. She was an exciting to talk. She described the overall goal of Twende, and the challenges Twende has overcome during its existence an her serving as Director.

The other leadership positions are held by Tanzanians. Deborah is leaving soon for a new job, and they have found a good fit in Tanzanian women. So everyone at Twende was very optimistic about the future.

Frank showed us around the space. It is actually a small amount of space they have, especially for the amount of projects and education they are doing. They have a milling machine, a lathe, a welding station, and an electronic station, plus other space for storage, etc. There were posters they used to present their work both in Tanzania and internationally.

Projects on Display

A Solar Mobile Phone Charger

This is a solar mobile phone charger. On the left is a pile of discarded solar panels from a company that was replacing them. Their original purpose was not a charger, but the solar panel works. On the left is what the students take home. The white box is a repurposed junction box with a USB port available through a hole, and inside is a simple circuit to safely proved 5 volts to charge a device. Students learn valuable skills and realize that they can build useful things. Many of the students have never used a drill or soldering iron.

A Spirit (Alcohol) Stove

The core of the stove is made out of the top and bottom of an aluminum soda can. The ring around it is made of a piece of discarded fencing. You pour a small amount of alcohol in it and light it. A small splash of alcohol can heat the water for two or three cups of tea or coffee.

A Flashlight (They call it a torch)

Here Frank is excitedly showing us a flashlight made from a plastic soda bottle, a piece of pipe, and four LED's. It involves a small amount of soldering. He was always talking rapidly, so his hand is blurred.

An Insect Trap

This is made out of an old jar. The circle is a small tube insects will fly or crawl through. once inside they have a hard time finding the way out. You bait it with a small piece of fruit and it ends up with many insect trapped inside.

New Technology & Independent Spin-Off Business

Using simple materials, one student made a press for squeezing oil out of an avocado seed. Avocado seed oil is very marketable. One big success story for Twende is that the former student transitioned from Twende technology incubator to a commercial enterprise.
One of Twende's services is to teach the skills necessary to start, and maintain a business.

So, Keep it up, Twende!

Safari in Arusha National Park

We had Sunday free in Arusha, so we scheduled a safari to Arusha National Park which is centered on Mount Meru. Arusha National Park is not as well known as the safaris we will go on later this week, but it was certainly worth the visit.

Our driver was here to pick up us up at 6:00 AM so we drove most of the way out to the park in the dark. We got into the park around 7:00. The first place we visited was a meadow with plenty of grazing zebras.

The first animals we saw are Kim's favorites - zebras!

As you can see from the picture, the sky was overcast as it was all day. Not great for viewing scenery, but the animals don't care.

Our driver, Benjamin, said all of the roads in the National Parks are dirt - no tarmac at all. Benjamin popped the top up in the back of the Toyota Range Rover and we drove like that all day. I spent a lot of time with my head out watching for animals. (I ended up with chapped cheeks the next day.

The view from standing and looking forward down a typical dirt road.

Here is the Range Rover. All of the safari vehicles are required to carry two spare tires and extra fuel. If you look closely you can see that the roof is popped up.

We saw many giraffes and waterbucks. The giraffes are very alert and will stop grazing and watch you.

This is a waterbuck. Kim remembered from our membership at the San Deigo Wild Animal Park, they have a bullseye on their rear.

One of the first giraffes we saw.

This is a very typical view. Giraffes are very alert animals. In contrast the waterbucks would just ignore us.

Giraffes usually stay in family groups. Here are two, but they were a part of herd of a dozen. It felt like Jurassic Park because just when we were watching some giraffes, several more would surprise from a different direction.

What is more adorable than a baby animal?

Flamingos!

There are several lakes in the Park that have flamingos. We stopped and watched for while. The flamingos noisily congregated. The ones in the foreground were wading with their heads upside down and swinging their heads from side to side while they walked. The guide said they are filter feeders, so they swish a lot of water through their beaks while they feed.

Here are more zebras.

This view has a bonus giraffe in the background!

We also saw suni and dik-dik's, both very small antelope. The suni are a distinctive red colored with large hindquarters, and the dik-dik is the smallest member of the antelope family.
