We’re receiving increased interest from Education focused organizations to use the BRCK to enable access to their content both online and offline.

One of the partners we’re working with is Studi Academy in Tanzania. Studi is passionate about changing how students in secondary schools in developing countries learn. They provide an online platform for students to engage with localized content adapted to local syllabus and language through educational animations & challenging quizzes, games to add fun and competitiveness and a structure that supports students to pass their critical exams.

School “advertising” in Mbagala area, outside Dar es Salaam

One of the schools Studi is working with is St. Anthony’s school, a secondary school on the outskirts of Dar es Salaam. They are using BRCKs to connect their computer labs to the internet, and more importantly to Studi’s content. The Head of Computer labs, is responsible for ensuring students can access Studi content easily.

We visited the school to see their experience first hand. Their BRCKs  have been working great though the mobile signal is intermittent. We ran some tests and  recommended that they get a unidirectional antenna as they have a cell-tower quite close to where the computer labs are located.

BRCKs connected to mobile internet from SIM cards

We also visited Acacia Secondary School, 30km from Dar es Salaam. Their school is 8km from the main road, sitting on a beautiful 55 acre piece of land. Before they receive BRCKs from Studi, it was important for us to run some tests to see what the best use case for their students  would be. For internet connectivity, we suggested that in addition to BRCKs, they should get an amplifier and an omnidirectional antenna. We also recommended that they cache content locally on the BRCK, as it has expandable storage capacity, giving the students a better experience than if they were trying to interact with the content online.

With many insights gained on how we can support our partners working in remote educational institutions, we continue to be excited about the potential to provide hardware and software tools to enable online and offline learning.

Farms and Ranch WiFi

I took off this weekend to test some BRCKs out in some of the more rural parts of Kenya. In this case, I was invited by Michael Nicholson who runs the cattle part of the El Karama Ranch situated near Nanyuki at the foot of Mount Kenya. The ranch is approximately 17,000 acres, and it has both a safari lodge and a lot of wildlife on it, as well as a 700-head cattle ranch. It’s an impressively well-run operation, and I got to see much of it.

The tower and gate at El Karama Ranch

It turns out that the ranch is about 13 kilometers from the nearest mobile phone tower, and with a normal phone sitting out at their gate, you can get some spotty edge connectivity. Fortunately, Michael is a tech-oriented type of rancher, so he was already familiar with modems and routers, and had educated himself on the types of antennas and WiFi repeaters he’d need. There was a lookout tower at the gate that already had two of Poynting’s amazing long-range directional antennas (which we call “swords” as they look like a weapon from a fantasy game).

He had a working setup, but his biggest problem was the modem would randomly shut off. This isn’t a problem on the BRCK, because as soon as the modem loses connectivity, we tell it to search again and reset and reconnect. A simple solution would be for Michael to replace his current Safaricom modem with the BRCK (see below).

Heading into the Bush

The next day I took off up further north, past Isiolo to the Samburu area around Archer’s Post. This is a dusty, dry and hot land fed by the Ewaso Nyiro River. The wildlife research teams at the Grevy Zebra Trust and the Ewaso Lions had asked if we could test out if they could get connectivity.

This elephant isn’t friendly, he took off after us for a bit

Grevy Zebra – endangered

It turns out that to get to their camps you have to drive through the Samburu National Wildlife Reserve, which is amazing and has plenty of animals of all sorts. We saw everything from crocs and elephant to Grevy zebra and oryx. As fun as that was, it took us 1.5 hours to get through the park and many kilometers beyond to get to their camps. These teams are in real bush country with no towers anywhere around them.

Me, standing at that ONE tree where you can get network signal

However, like almost anywhere you go in Kenya, there’s always some random tree that you can stand under and get connectivity (that’s me at said tree, above). They knew where these were, so we started to visit the locations to see what might work. Of the 5 areas we tested, one had a strong signal but was a couple kilometers from the camp. Another had a weak and usable signal near camp, and one had a possible signal in the middle of the Ewaso Lions camp. Very positive, and doable!

In the testing kit, I take a couple directional antennas as well as a small omnidirectional antenna to walk around with. On top of this, I have a way to mount an amplifier (booster) in the car to increase the signal gain on the antennas. It’s a great bit of testing kit, and it proved out incredibly well.

My suggestion to them is that they’ll need to raise a small pole on the top of their hill. Add a Poynting antenna, Voltaic solar panels for power, a BRCK and an amplifier. If they do this, we’ll likely test out our BRCK Extender at this location as well, which increases the WiFi range from about a 10m radius to approximately 900m. Since both the Extender and the amplifier need external power, there will need to be a small battery which is charged via solar. This whole concoction will run just over $1000 and should be fairly hands-free once setup.

Summary

It turns out that BRCKs end up being a great solution for some of these rural and off-grid type places. While we can’t drive everywhere to do testing for everyone, we do try to get out and see what’s going on and see if we can help. It gives us a better understanding of our customers knowledge, and also a better feel for their pain points.

With all the hubbub about the team’s epic three week dash to South Africa and back, some may have forgotten that only a month and a half ago, the other half of the team were cruising Lake Victoria and the Nile in Uganda. The video edit is done, though, so we’re bringing it back!

We started off with a plan to work with Johnny Long of Hackers for Charity to connect schools around Jinja to the internet and learn from local educators how we can build technology that meets their needs:

We wound up visiting the Living Hope Secondary School on Lingira Island in Lake Victoria:

On the boat ride back, we broke out our OpenROV underwater exploration robot:

Finally, we took a raft trip down the White Nile to play with antennas and sensors, to see how the Internet of Things could help conservation efforts in threatened ecosystems:

http://brck.com/2014/11/how-the-internet-of-things-can-help-save-our-rivers/#.VJP_TACU

You can see all that and more (read: zany BRCK team adventures) in the video above. It’s been a heck of a year for us here in Nairobi, and we can’t wait to see what 2015 brings! (Did someone say they need a weather station on Mt. Kenya…?)

You’ve been hearing a lot about our recent trip to Uganda, and we’re not through yet! In addition to working with Hackers for Charity, connecting schools around Jinja, and wirelessly controlling underwater robots, we wanted to explore the IoT side of the BRCK, too.

A number of people we’re working with are keen on using BRCKs to remotely connect sensors and other objects to feed data back over the internet. Some of the uses we get most excited about are around conservation, ranging from tracking vultures to locate poaching kills to remote weather stations in the savannah.

Two projects we know of, Into the Okavango (http://intotheokavango.org) and the Mara Project (http://mara.yale.edu ; http://mamase.unesco-ihe.org), are deploying networks of sensors to monitor entire ecosystems. By tracking water quality throughout the Okavango Delta in Botswana and the Maasai Mara in Kenya, each hopes to improve our understanding of these fragile environments, and by publicly posting the data (as well as pictures of their own expeditions) on their websites, they hope to inspire further appreciation amongst those who may never get a chance to visit these amazing places in person.

When we first started talking about going to Uganda, home to the source of the White Nile flowing out of Lake Victoria, we knew we had to find a way to get out on the river and try our hand at collecting environmental data via the BRCK ourselves. It just so happens that Paul, one of the expedition team members, was a river guide for seven years in Colorado before coming to Kenya, and had found out about an expedition being planned by Pete Meredith down the Karuma to Murchison Falls stretch of the Nile.

This stretch is home to the largest concentrations of hippos and crocodiles anywhere on the Nile, and has been rafted less than 10 times in history, only once commercially. It’s home to some of the biggest, most terrifying whitewater in Uganda – a country known for big, terrifying whitewater. Uganda is also a country that is industrializing fast, with hydroelectric power stations playing a key role in meeting fast growing energy demand.

All these new dams mean that rivers in their natural flow are disappearing quickly. The Bujagali Dam near Jinja covered 388 hectares in reservoir, flooding several miles of pristine whitewater. A new dam under construction near Karuma threatens to seriously affect the wildlife that concentrate downstream, and the Murchison stretch may no longer be runnable after 2018. With almost 85% of Uganda’s population unable to access electricity, the case against building more dams is hardly clear cut, but it does mean the time to learn from, share, and experience some of the most unique ecosystems along the Nile is running out.

As a team of gadget-headed engineers, we figured a good first step would be to have an affordable, reliable platform for collecting and disseminating information about these ecosystems. While the BRCK itself runs on an Arduino compatible microprocessor, we included a blank AVR chip with direct access to the pins through a dedicated GPIO port on the back. In Jinja, our lead RF engineer Jackie quickly soldered up a pH and temperature sensor kit to a GPIO MRTR, and off we went.

After much debate, and despite being a generally adventuresome and outgoing bunch, the Murchison stretch proved to be a bit too much for some of our team, most of whom had never rafted before. (Mention the word “Murchison” around here and even the local guides have to suppress a shudder of anxiety. Pete is still planning an expedition for springtime, for those with a serious bug for adventure and not too tight an attachment to this world – http://www.nalubalerafting.com/expedition.html.)

Instead, we opted to run the 30 or so kilometers of the Nile north of Jinja with Nalubale Rafting. Our goal was to get far enough away from “civilization” to test both the BRCK’s connectivity and the GPIO setup. The first day on the water, we hit five major Class IV/V rapids, including a three-meter tall, nearly vertical drop.

Along the way, we plugged in our MRTR and dipped our sensors into the water. Not being hydrological engineers ourselves, we weren’t quite sure what to do with any data we might collect, but we did learn some valuable design lessons around using the BRCK with the GPIO port (such as the need for a tighter connection between the MRTR case and the BRCK’s body). Ultimately, the hardware worked great, but some work remains on the software side to view our data on the web. We’ll be working on these tweaks and incorporating them, along with a means to visualize data fed through the port, into future updates.

After a hard day of paddling (and no small amount of swimming, only some of which was involuntary) we found ourselves at our campsite overlooking the river. It’s hard to imagine what this place will be like in 10 years. There’s nothing quite like eating dinner around the campfire, away from the constantly connected buzz of the city to make you appreciate the stillness of the wild.

As an expedition tech company, believe me, we get the irony. We still believe sharing these places before they disappear is the best chance we have for preserving them. There are far too many people who will never get to raft the source of the Nile, but we hope we can build a platform through which many more can experience it, if only vicariously.

It’s that time of year in Kenya again – the “short rains” are coming, there’s a slight chill in the air, and every now and then, the sky opens up for a brief deluge of water. It’s hard to avoid getting wet during the rainy season here, something we’ve designed the BRCK to handle (in small doses, at least).

It just so happens that one of our key partners, Hackers for Charity – who help schools and nonprofits solve technology related problems so they can get on with their jobs – has some interesting problems they are trying to solve in their work with schools around Jinja, Uganda, at the source of the White Nile and on the shores of the largest body of water in Africa, Lake Victoria. Time for a water-bound expedition, methinks.

Going into the wild to test our products in some of the most remote and challenging environments we can find is a core principle behind how we design in Africa, for Africa; to eat our own dog food, so to speak. Last year we took a trip to the barren shores of Lake Turkana in northern Kenya to live stream one of the best views in the world of a hybrid solar eclipse. Despite having that view blocked by a massive dust storm, the BRCK performed admirably, and we learned a lot about how to design for reliability in extreme weather. You can watch the video here:

This year, we’re taking a slightly different tack. When we started making the BRCK, we found some of the greatest need for affordable, reliable connectivity is in schools. We’ve been pushing hard for solutions in the edtech scene ever since, working with partners such as eLimu, Mozilla, and Sugata Mitra’s “School in the Cloud” TED prize wish to develop projects around innovative caching solutions to cut down the costs for data, a Raspberry Pi MRTR to turn your BRCK into a remote server, and testing connectivity solutions in schools from India to Ghana.

When Johnny Long, the founder of Hackers for Charity, first contacted BRCK back in June, he showed us his own attempts to build a rugged and reliable remote connectivity device. It looked remarkably like some early BRCK prototypes. It was clear we were trying to solve the same problems, and that by working together we could make a dent in the challenges facing students in rural Uganda. We set Johnny up with a BRCK and gave him free reign to hack it however he needed to build the solutions that worked for the schools he and Hackers for Charity supports.

At last, we have the chance to work with him directly. On Sunday, six of us will load up the Land Rover and make the 12-hour journey from Nairobi to Jinja. Johnny has graciously offered to host us at the bed and breakfast he and his wife run while we set about training up the Hackers for Charity staff on the technical aspects of the BRCK, testing antennas and signal amplifiers, and ultimately working to get several local schools online.

One of these schools is on an island in Lake Victoria, an hour and a half journey from Jinja by boat. Seeing an opportunity to kill two birds with one stone, we decided to bring an OpenROV with us. We’re hoping we can work out a way to control the ROV through the Ethernet port on a BRCK, meaning we could “wirelessly” pilot the ROV through the waters of Lake Victoria. Since Ushahidi, our parent company, partnered with OpenROV to create OpenExplorer.com, a platform for sharing the fruits of grassroots exploration with the world, you’ll be able to follow the progress of the entire expedition at:

https://openexplorer.com/expedition/brckexpedition2014

As if this wasn’t enough, Jinja also happens to be at the headwaters of the White Nile, with some of the best high-volume whitewater in the world. A BRCK expedition can’t be all bed and breakfasts, so we looked up Pete Meredith, one of the leading explorers of the Nile (he’s ran it from the furthest source in Rwanda all the way to the Mediterranean), and Nalubale Rafting to help us spend a couple days exploring the river.

In addition to the edtech sphere, some of the primary use cases that are emerging for BRCK’s technology are around conservation. We’ve been talking to people who are monitoring the effects of hippo feces and wildebeest carcasses on water quality in the Maasai Mara and streaming live data on animal sightings and pH levels (and much more) in the Okavango Delta in Botswana. You can read all about the Mara Project and Into the Okavango here and here:

http://mara.yale.edu ; http://mamase.unesco-ihe.org

http://intotheokavango.org

Both of these projects have very kindly shared info about their open-source sensor package designs with us. We’ve put together our own package to test pH and water temperature, and will attempt to stream data from the river as we go. This will be a fantastic learning experience as we further develop IoT use cases for the BRCK, and we hope will prove a valuable source of insights for how we can better enable our conservation partners to inform the wider public about the amazing work they’re doing, and the importance of these fragile ecosystems.

So, with a very full docket, our soldering irons packed, and our heads and hearts full of excitement, the BRCK team is once again setting out into the wild blue yonder. Get ready to follow along – BRCK Expedition 2014 begins tomorrow!

(Note: I’ll do another post later on the challenges, constraints and opportunities of designing in Africa, but here’s a real case study for why it’s important.)

Reg and Philip spent a day last week at Amboseli working with a group of conservationist called Lion Guardians, who have a permanent camp about 10km from the edge of the Amboseli National Park. They went at their request to see if BRCK could solve their current connectivity challenges before they invested in satellite equipment.

A Problem of Too Many GSM Towers

The situation is that Lion Guardians can get decent signal from one operator (Airtel) but very slow data connections. They can also receive signal from another mobile operator (Safaricom) in certain physical locations within the camp but it requires standing in one spot and holding their phone in a certain way. One of the workers is able to send/receive data by holding his laptop in one of these spots to get a decent data connection.

Reg and Philip spent a couple of hours surveying the signals with a combination of the OpenSignal Android phone app and the Wilson boost equipment. They found a very strong Airtel signal but it only provided edge data. They found more than one Safaricom signals, one of them provided no data – even with strong signal – and another provided reasonable edge performance. However, when locating in the exact spot identified, they were able to get 3G signal and faster data.

After attempting to secure a reliable signal from the identified 3G tower (they were tracking tower IDs) they stumbled upon a hypothesis for this type of situation, which isn’t an uncommon issue.

The hypothesis is that the 3G tower is the tower that is furthest from camp and therefore has the weakest signal. From most locations in camp, one of the stronger signals from the other towers is given preference and no/poor data connections are the result. However, when standing in a location that blocks the stronger towers (due to a building and a tree), the weaker signal take precedent and a solid 3G connection is possible. As we understand it, the device will usually “hear” several towers and then has to make a decision about which one it’s actually going to talk to. Signal strength, not quality, tends to be the easiest metric to engineer for.

A BRCK GSM Lock-on Solution

The opportunity is to create a means of forcing the selection of a specific tower ID even if other towers have stronger signals. In order to achieve this improved result we are going to need to address two principal issues:

• The first is that we have to develop a means of indicating to the BRCK which tower IDs are acceptable and which should be rejected.
• The second is to develop a means of doing effective site surveys that will allow anyone to identify the best carrier/tower combination for a given location.

If we can do this then we should be able to offer a very competitive performance improvement in locations with mixed/limited coverage. You can imagine being out with your BRCK in a new environment and getting a list of possible connections, and choosing the best one – not the strongest one, in the future.

This observation further reinforces our “engineered in Africa” position since we would likely not encounter this scenario in the West. The fact that Safaricom has multiple towers but only some of them have good data connections is a very unique problem for the emerging markets.

With respect to Lion Guardians, they have been told that a new Safaricom tower is coming that will be close to camp. This will likely provide them with the performance they are looking for. However, they will still need a BRCK since they want to have a single, reliable, self-powered connection that is shared using an outdoor Ubiquity WiFi AP.

With Christmas just days away, and with some of us just getting to our holiday shopping, we at team BRCK wanted to help you find that perfect last minute gift for the hardware hacker or adventurer in your life. Most of these items are things we’ve used and depend on, the rest are just cool!

This is an easy one for the makers on your list. I can’t think of a more useful or fun stocking stuffer than Sugru.

Sugru is a strong, colorful, moldable plastic that sticks to almost anything in it’s origional. After it air-cures it’s a firm, lightweight plastic with a foamy feel. All you have to do is open up the foil pouch, roll the putty around a little to get the chemistry going, and then start making. It sets up in about 20 minutes and cures in 24 hours.

We joke (kind of) that the first BRCK protypes were held together almost entirely by Sugru, Kapton Tape, and Love (we didn’t have budget for much else!). We’ve used it for loads repairs on and off the field, and early on we actually used Sugru to make quick and dirty button covers and rubber feet.

Great for someone who’d like to get into hardware hacking but doesn’t know a lot about it yet.

Sparkfun’s Proto-Snap is an intro to Arduino class on a single PCB. Basically it’s an Arduino Pro Mini 328, a USB Programer, buzzer, RGB LED, Push Button, and a little bit of Proto-board all pre-wired onto one PCB about the size of a credit card. This means your budding engineer can focus on learning the Arduino Scripting language with out the frustrations that come with trouble shooting code AND hardware at the same time. Once they feel comfortable with the language, the PCB is perforated, so they can start breaking off the extra components until they have a good, simple AT-MEGA 328 prototyping board with extras for going forward.

We haven’t used this yet, but like Sugru, it seems like one of those things that could become indispensable once you figure out exactly what it can and can’t do. Because it’s a paint the first thing most people will think about is fabric, but i’m really curious about painting circuits onto wood with it. It might also work well as solder-less field repair solution, but we’ll have to test it to find out.

Gold Plated Teensy3.0 with some extra upgrades. That’s really all you need to know.

Teensy3s are like any other animal in the Arduino compatible menagerie with one big exception: they’re powered by a 32bit ARM M4 processor. Comparing a Teensy 3.1 to an 8bit wonder like the Arduino Uno is like comparing a ’98 Geo Metro to the new Ford Fieta ST: yes they’re both useful and tinny, but only one of them goes very, very fast.

Beyond the gold plating, other upgrades to the 3.1 from the original are 4X memory (64K vs 16K), *TRUE analog output*, two A/D Converters, and 5v tolerance on the digital pins (though it still needs 3.3v for everything else) which is super handy if some of your accessories run at 5v. If you know someone who’s been using an Arduino board for a while, this will be a welcome upgrade. The Teensy 3.1 is one of those tools that will never be the bottle neck of your ambition.

We’ve found that many small solar panels quickly show their age in the face of real adventure.

But, not Voltaic Panels.

Voltaic designs their products with aggressive outdoor use and environmental responsibility in mind (less breaks == E Waist!) and as such, their panels are simple to use, light, strong and weather resistant. It also means they can offer a two year warranty. Also they pack more punch than almost anything else in their size class.

Your tech-head adventurer will love Voltaic’s 6 Watt Kit. It’s got a enough juice to charge most portable electronics but isn’t massive or messy (it’s 2013, why have a folding panel kit?). The kit comes with Voltaic’s V15 Battery Pack which is SUPER useful on it’s own for evening charging or even in town as a portable power station for your phone when wall sockets are scarce. I get two full chargers on my iPhone out of the V15 before it’s dead. The construction on the V15 is good as well.

If your out in the bush and you REALLY need to solder something, there’s a chance the thing you need to repair is also your primary source of electricity, which means your iron will have a hard time heating up.

Enter butane soldering irons.

Think of them as cordless soldering irons powered by old fashioned fire instead of electricity. Butain irons are nice for travel because they take up very little space compared soldering stations. Most butane irons also have the added ability to double up as crude heat guns for reflow and heat shrink, or direct flame soldering torches for soft metal work. I like the Weller PyroPen Jr because it fits a sweet-spot between performance and price and all things being equal, Weller tips tend to last longer.

There and Back from BRCK on Vimeo.

A quick sneak peak at our adventures up country thus far.

This morning finds the BRCK team in Nanyuki, only about 3-4 hours outside of Nairobi. The same place we were supposed to be having breakfast yesterday, not today. A rather inauspicious start happened about 30 kilometers into the trip when the Land Rover decided it was going to have some cooling problems.

After two hours of working on solutions, we realized that this Land Rover just wasn’t going to make it. Too bad, as it had two tanks and better range than most. Fortunately, Fady Rostom (of Ark/Bonk) is traveling with us. He offered up his Land Rover 110, and we quickly got in touch with a mechanic in Nairobi who put a roof rack on his vehicle in about 30 minutes.

1pm found us with all equipment unloaded near Thika town, on the side of the road. 5 tires were changed from one Land Rover to the other, and we repacked the new vehicle. Finally, we were on our way (again)!

In hindsight, what was extremely disappointing at the time ended up happening about the best time we’d like to have seen a problem like that develop – in the beginning of the trip near the big city, where we could still make a change.

We got into Nanyuki in the evening, after a nice cold rain hit us, much to the chagrin of those of us on motorcycles with only mesh jackets on. Taylor had his full rain gear (who we had been making fun of earlier due to the heat), and while we froze he rode in relative comfort. Dinner was at Barnies, and then a shack that makes and sells the best cheeses that we’ve ever found in Kenya, called Silent Valley Cheese. 6 kilos of cheese later we found a house owned by a friend to sleep at for the night.

This changes the stages of our trip, and now we’re very glad that we built in a buffer day for the drive up to Lake Turkana. We’ll still arrive the day before the eclipse (Oct 2), but in the evening instead of the morning. Our route now entails an early morning offing from Nanyuki, final fill up of fuel in Isiolo, then off road around Laisamis towards Ngurunit and on to Kurungu and Soth Horr for the night.

This next section along the edge of the Matthews mountain range is one of the most scenic places in Kenya. We’ll stop along the way for some pictures, and then get into Kurungu in time to test the Wilson amplification antennas. The point of these amp antennas is to extend the range one can be from the mobile phone tower to get internet connectivity. We’ve used one before in Lamu, now we’re trying it in the bush, and with the BRCK.
