One of the challenges while traveling across Africa is connectivity. The experience of getting connected is often quite slow and unpredictable, especially when you are transiting through countries with places to be before  dark. Yesterday was a case in point. 

We were trying to get an MTN Line in Zambia so that we could connect the BRCK and test it while on the road across Zambia. It took over an 2 hour to get a SIM, have it registered, activated and ready for use. With over 960KM to cover, it is simply time we couldn’t afford. A the MTN shop, just getting the SIM took over 40 mins,. This took away precious time and even after an hour, we had to drive away without registration, which meant we could use the SIM. The instruction was to dial 111 every 10-20 mins until we were registered. This took another hour before we were good to go. 

The second challenge was the data bundles. We are going to be in Zambia for 2 days. We needed a plan where we could be online, unlimited, for 2 days. This does not exist. We could either buy 1GB each time and do the process all over again when it ran out, or buy a month-long unlimited plan, which was quite expensive. We are having to load 1GB each time. The system doesn’t warn when about to run out, it just cuts off. Its up to you to figure out if you are too far in the bush and therefore with no service, or whether it is your bundles that have run out. The instruction to check are nowhere accessible at the moment. I am sure if I called I would get them, but I shouldn’t have to. There is need for companies to consider not just the ability to connect people, but the experience of doing so to. It is not enough to have branding and cool premises, it is actually the service experience that primarily counts.

Eventually we got it going and I think the BRCK does a remarkable job, especially with the omni-directional Antenna. We steadily got 90+ connectivity whenever there was a signal, even when the signal was pretty weak out in the bush. 

Catching up on a few updates at once here, you can read about Day 2 of our trip here.

It’s 6am in Lusaka, Zambia as I write this. The last two days have been a blur as we covered over 1,700 kilometers from Dodoma to Lusaka in what can only be considered as marathon sessions from sunup to just after sundown. Fortunately, both Tanzania and Zambia have some of the best roads we’ve seen, and the motorcycles and car all behaved well with only one slow puncture the whole way. We took small breaks every 100-200km in order to rest and move around a bit, but we’re still quite sore and ready for this day to do no travel.

The border crossing from Tanzania into Zambia at Dunduma left a little something to be desired. What felt like it should have taken about 1.5 hours at most, ended up taking 3+ hours, which meant our last 50km into a campsite were done in the dark on the only section of bad road we’ve seen. People did warn us of this, so it wasn’t unexpected. However, the reason wasn’t because of long lines of trucks slowing us down, it was due to inefficiency in the process itself at both immigration and customs.

From here, our days get a little more sane, with a run down through Victoria Falls into Botswana and then finally Johannesburg. As an aside, it turns out that half-way between Nairobi and Jo’burg is almost exactly at a small town called Serenje, Zambia – 2,200km from each.

Time at Bongohive

We pushed so hard to get to Lusaka by now so that we would be here in time for the events at Bongohive, Lusaka’s tech hub, which were all scheduled for today.

1pm – Demo of BRCK (Philip Walton and Reg Orton of the BRCK team)
3pm – Meeting with Startups (Mark Kamauof the iHub UX Lab) – HCD, UX, DT
4:30pm – Meeting with Startups (Erik) – Investment readiness, experiences with Savannah Fund, getting into new markets etc
6pm – Keynote at Startup Weekend Lusaka (Erik and Juliana Rotich)

Lukongo Lindunda is the co-founder of the space, and we’ve known each other for years, since before they got it started back in 2011. I’ve been looking forward to seeing everyone here in the tech space for a while, and I’m interested in hearing what’s brewing in the startup scene.

Some of the startups that I’ve heard about from Zambia include:

• ShopZed.com
• Bantu Babel
• Venivi
• DotCom Zambia, BusTickets
• TeleDoctor
• SCND Genesis

If you’re part of the tech community in Zambia, I hope you can swing by, and we’re all looking forward to seeing you as well.

Lessons From the Trip

Since we’ve started this trip I’ve been thinking a lot about communications, as one would expect with a BRCK expedition, and especially mobile comms. We outfitted the truck with a omni-directional Poynting antenna on the front bumper, hooked up into the car, where we can also connect it to an amplifier if needed. As we drive down the road, we have a pretty good mobile WiFi hotspot, as long as we’re in range of a tower.

The mobile phone kiosk, a mainstay of rural Africa

The last few years have seen a number of countries implement a registration process to buy SIM cards (ostensibly this is for security though it’s not been proven to be useful for anything more than big brother activities by governments). Even buying a SIM card is then a process of identification (usually passport or drivers license), so you have to budget for that 30-60 minutes to get that done, since it’s usually filling out a form by hand.

Registering an MTN SIM card in Zambia

You then purchase credit for the SIM card and load it up – this is the easiest part.

Now you get into the “mystery meat” part of the process, which is how do you turn that airtime you just bought into internet credit? Each network in each country has a different way of doing this, some combination of USSD or SMS to get it going.

A couple things come to mind now when we look at the BRCK.

First, we need a terminal screen in the BRCK interface for us to do all of this from the device itself. Right now we find ourselves popping out the SIM card and using a phone (Mozilla’s 3-SIM phone is amazing for this purpose), and then inserting it back into the BRCK when done.

Second, there needs to be a database of this “airtime to internet data” information that we can all use. I’m not sure how best to get this going, but I know it would be immensely useful when you drop into a new country to have this at your fingertips.

We’re already working on the first issue, of USSD/SMS interface, but it’s complicated, so it’s taking longer than we’d like. This trip is about learning, and we’re already finding a lot of things to do better. Look for more posts on the BRCK blog from the others as well.

We ended our first day well at an incredible campsite in the middle of Tanzania. We mostly got to bed at a reasonable hour with an agreement to get moving at 6 and wheels rolling by 7. We hit the first but missed the second. It wasn’t that we were wasting time but there is always a bit of effort to get ourselves into high-performance, expedition pace.

The early part of the morning was spent at a proper speed on some of the best roads in Africa. We would hit towns of various sizes every 40-50 kilometers and we learned to recognize the size/status of the town based upon the number of speed bumps and cell towers. On the bikes it was easy to lift up out of the seats and take the speed bumps at a reasonable speed. The truck on the other hand had to slow down. In addition to the impact of the speed bumps, the truck was a target for every police stop. The bikes just waved as we went flying by. We really were in a zone for a couple of hours as we let the kilometers roll by under our wheels.

And then things changed… A lot!

We had a choice this morning to either go the eastern (shorter) route or the western (better) route. Everyone (I literally mean every human we know who has ever even heard of Tanzania) told us to take the western route. We, of course, decided to take the eastern route. They were right. We were wrong.

It started off reasonably ok with a bit of hard packed dirt. Although my bike wasn’t really designed for this kind of stuff, the other vehicles are in their element when the tarmac ends. And then things got worse. The road went from hard pack to fresh-fresh (talcum powder like sand). We would have sections with washboards so bad that our bikes would bounce all over the road. Then we would have sections with huge rocks that did their best to total our vehicles.

Reg had the first incident when he slid the truck in the fresh-fresh and ended up in a ditch. Nothing serious but we found out a few kilometers later that he had bounced the rear spring out of its mounting. We subsequently found out that the spring had rubbed on the sidewall of the tyre. The tyre (and rim) met their end on some very difficult washboard when they disintegrated into many, many pieces. No injury, but it was another delay on an already delayed day.

Although the bikes faired better mechanically (the only issue during the day was a broken box mount on Joel’s KLR), the riders suffered greatly. As we watched the remaining distance to Dodoma very slowly trickle down, our bodies were thrashed royally by the terrain. Sore hands, dust filled eyes, and shattered nerves from the many close calls in the loose dirt. When the dirt wasn’t giving us grief the buses that would fly by at uncontrolled speeds would nearly knock us off the road. We would stop frequently but the breaks were always too short and the pressure for pushing on too great.

We had intended to be in Dodoma by 10am where we were going to pick up Mark Kamau and Juliana Rotich. The plan was that we would then keep going to Iringa and spend the night closer to the Zambian border. As the hours ticked along and the kilometers did not we started to realize that our decision was going to have a significant impact on our overall schedule. Instead of making it past Iringa, we were going to have to fight to just make it to Dodoma. With about 70km to go we stopped at a police check to ask how much farther to the tarmac. The cop answered 20km but we are generally suspicious of time and distance responses from people in rural Africa. He was actually spot on and, 20km later, we rolled our bikes onto beautiful a made tarmac road. We had to hang out for a bit as Reg was dealing with his disintegrated wheel but we all breathed a sigh of relief to be back on the good stuff.

As we flew along towards Dodoma we settled into the reality of needing to adjust our schedule slightly for the remainder of the day. As if we had not had enough punishment for our decision, we suddenly found the tarmac ended and we were once again getting pounded on the loose dirt. We knew that we weren’t far from Dodoma and we were confident that the capital city would have only paved roads.

We were wrong again.

The dirt took us all the way into Dodoma – with pavement showing up once we were in the town proper. We found the rest of our team hanging at the New Dodoma Hotel and we used their wifi to search for accommodations south of the city that would put us on our path towards Zambia. We quickly found out that the New Dodoma Hotel was the only option available and so we relented to real showers and a night in real beds. While we still had daylight we did a full round of mechanical checks and fluid top ups on the vehicles. We reworked our route for the next two days going into Lusaka and we enjoyed a nice meal together as a team.

Although today was not anything like we expected when we woke up this morning, we once again validated why we do these expeditions. It is simply impossible to know what Africa can throw at you until you get out there and experience it for yourself. We are learning a lot about what is required to actually be rugged-enough for Africa. We are seeing how critical reliable technology is in remote and difficult situations. We are improving our ability to persist and succeed in the face of insurmountable odds. Finally, we are learning to adapt to our circumstances and not lose sight of the bigger objectives. These aren’t new lessons for us but they are lessons that we need to be continually reminded of as we attempt to build BRCK into the kind of company that can have the kind of impact that we want on our greater community.

It wasn’t the day that we hoped for but – with all vehicles and riders still in this expedition – it was the kind of day that we will look back on with fond memories. We will tell stories of this day for years to come and, hopefully, somewhere in the dust, oil, sweat, and tears there was the start of an idea that will eventually find its way into a BRCK product. For that one goal, today was well worth it.

(By Erik)

I’m writing this blog post using my Mac, connected to a BRCK which is connected to a satellite internet connection using an Inmarsat iSavi device, somewhere about 100km from Arusha towards Dodoma. Inmarsat gave us this test device, a small unit, made for global travelers, so we could test out what worked and give them feedback on their tools. It also helps us figure out what connecting to the internet looks like when you’re beyond the edge of the mobile phone signal in Africa.

Here’s Reg, using his phone to do the same at our campground this evening:

The Journey

We left at 5:30am from Nairobi to beat the traffic out of the city. With the beautiful new roads, we were at the Namanga border by 8am and cleared by 10am. Before you go on one of these trips, make it easy for yourself and get the following:

• Carnet de Passage for each vehicle (get this via AA)
• COMESA insurance (get via your insurance company, or buy at the border)
• International driver’s license (get via AA)
• Yellow fever card
• Passport

By noon we were in Arusha, and took a chance to see the cafe that Pete Owiti (of Pete’s Coffee in Nairobi) set up with some Tanzanians, called Africafe. If you ever find yourself in Arusha, this is the first place you should go. Great food, good coffee, right in the middle of everything.

Knowing we were only going about 100km more today, we set off around 1pm. We got to a roundabout, and I knew which direction the main road was, so even though Philip mentioned we should go right, I went left to the main road. 45 minutes later we realized my mistake when Philip checked his GPS and realized we were further away than we were supposed to be.

Lesson learned: always listen to your cofounders (especially the one with the GPS).

With many sighs, we turned around and went back to Arusha, where Reg had been smart enough to stay with the Land Rover when he realized we went the wrong way. We quickly split off in the correct direction, aiming to get to the camping spot by 4pm latest.

As we were sitting in traffic in Arusha, Joel says, “Erik, your bike is smoking.” I replied that it was likely just the car I was parked next to. Nope. Sure enough, I was leaking oil… For those of you who don’t ride motorcycles, this is the last thing you want to hear when on the front end of a 4,400km trip. I ride a 2007 Suzuki DR650 – they have some of the most bullet-proof engines, and are perfect for Africa’s roads.

Working on the DR650 in Arusha

Fortune smiled upon us, and we were pointed towards Arusha Art Limited, which turned out to be an amazing garage (the best I’ve ever seen in Africa). Their director, Hemal Sachdev helped us out by helping to troubleshoot what could be wrong, and even fabricating a high-pressure oil hose, with compression fittings on the spot. There was oil everywhere, so we washed it off and kept going.

Lesson learned: there are a lot of people willing to help you in your journey, especially if you ask nicely.

5 km down the road, I was still smoking… Thanks to Hemal’s help, we knew what the problem wasn’t. It was now that we chanced to notice that the problem seemed to be coming from the timing chain setting hole. We realized this could be filled by a normal M5 screw, so got trucking to the campground where we could let the engine cool down and screw it in.

Now, I sit here in Wild Palms Camp, some place we saw on the side of the road near the Tarangiri game reserve. For 10,000 Tanzania Shillings ($6) each, you get a patch of ground to put a tent, there is a banda with table/chairs, and there are even some showers and toilets. Not real camping, but definitely nice after a day on the bike!

(Republished from Erik’s blog)

Two days from now we begin a BRCK overland expedition to South Africa. Like any of our trips, it is meant to be fun and adventurous, while at the same time giving us the opportunity to stress test our product beyond the norm.

In the vein of our past expeditions to Turkana and the Nile, this one is on the edge. We’re taking 3 motorcycles and a Land Rover from Nairobi to Johannesburg in time for Maker Faire Africa on Dec 3-6.

As usual, we’ll have a couple guests, or “shotgun riders” as we call them:

On the way south: Juliana Rotich (Ushahidi, iHub, BRCK), and Mark Kamau (UX Lab lead at iHub).

On the way north: Aaron Marshall (CEO, founder of Over, Africa’s biggest selling IOS app), as well as Matt Schoenholz (head of the Kitchen Studio at Teague which focuses on prototyping and making).

You can keep up with us:

• On the BRCK blog (here), Twitter and Instagram
• On the WhiteAfrican blog, Twitter and Instagram

A Dash South

If you do the math, you’ll realize this is more of a mad dash south in time for the event, covering 4,400km in 9 days. Here’s what the route south looks like, from Kenya through Tanzania, Zambia, Botswana and into South Africa.

Nairobi to South Africa – southern leg

The journey north takes us through Zimbabwe, Mozambique, Malawi, Tanzania and back to Kenya, which we’ll take a little slower.

The People We’ll See & Events We’re At

We do have plans for a day off along the way. We’ll be stopping to visit our friends in the Zambian tech community in Lusaka. The Bongohive has been kind enough to host us, and we’ll be hanging out there, doing BRCK demos for techies and businesses, and I’ll give the keynote that evening for the beginning of Lusaka’s Startup Weekend.

Since I’m a founding organizer for Maker Faire Africa, I’m excited to go back, and this time have a product of our own to show for it. Besides demoing the BRCK and sharing how to build a hardware business in Africa, we’re also going to have some fun hacking on the devices with whoever is around and wants to play with them. We’ll have a couple of our engineers on hand as well.

Gearbox, our new prototyping and making initiative in Kenya, is a supporter of this year’s MFA too, so I’ll be able to speak to that and will have one of the Gearbox team with us at the event.

On the way back North we’re stopping in Harare, Zimbabwe to meet up with the tech community there. We’ll largely spend our time around the Hypercube, though plans are underway to get together with members of multiple tech spaces.

Testing BRCKs and Electronics

There are a couple new things we’re testing on this trip, three of which I’m extremely excited about:

When you add a RaspberryPi, a hard drive and another 8 hours of battery to a BRCK, you get a BRCKpi Microserver

1. BRCKpi – this is our RaspberryPi + BRCK device – it’s an add-on to the BRCK (we call those MRTR, as in “bricks and mortar”). We launched it last month with Mozilla in London, and are targeting it primarily at schools and clinics in Africa. However, we know there are a lot of other use cases for it, and one of those will be as a media server for our images and video on this trip.

Real off-grid, portable internet in Africa.

1. Satcoms – we’ve been thinking a lot about how we can extend the BRCK beyond the edges of the network, so that it’s the one internet device that’s smart enough to pick the right connectivity type depending on what it can sniff around it. To that end, we’ve been having great conversations with Inmarsat and we’re testing out their newest product, the iSavi (not even on the market yet, first one in Africa). Internet speeds are comparable to cellular networks at up to 384 Kbps down, and 240 Kbps up. It’s much smaller and more portable than a BGAN, so we’re excited to pair it up with the BRCK, stress test it and see how it goes off-grid.

Some of the best antennas on the market, made in Africa

1. Antennas – We’ve tested some of Poynting’s antennas before, and they’re some of the best we’ve ever found. This time around we’re testing their mobile units, paired with amplifiers which we built into the vehicle, in order to see if we can create quick, deployable units at the edge of the grid. Of course, Poynting is a South African company too, and as one of our partners, we’re going looking forward to seeing them in-person for the first time in Johannesburg.

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.

The BRCK team is back in Nairobi! We’ve just spent six days testing BRCKs in the wild and learning from those who use our products to solve problems they face everyday. We’ve been a bit remiss in providing regular updates as we go. It turns out Jinja, Uganda, is an exciting place, and we were running from sunup ‘til sundown to fit everything in, leaving little time for blogging. We’ve now got hours of footage and records of conversations to go through, and we’ll be filling you in over the next week or two.

Our last update concerned a school on Lingira island in Lake Victoria. Despite having only a small village on the island, the school’s 12 teachers serve over 250 students from neighboring islands, too.

One of the head teachers, Frederick, showed us around – his passion for chemistry was apparent in the way he described the school’s water filtration system (using electrolytic chlorination to disinfect the water) and the solar power system that runs it. He was extremely gracious in sharing his hopes for delivering more practical, hands-on content from the web (he has his physics students building rheostats from scratch, determined to help them build an understanding of technology, even if it’s not readily available locally).

We tested a number of different types of antennas on Lingira and got the school connected. With the help of Hackers for Charity, over the next few weeks the “Living Hope” Secondary School will be building new content from the web into their curriculum, and inspiring their students to ever greater heights of achievement.

Context is Everything

We’ve been working with educators and content providers here in Kenya over the last six months to understand how technology can make their lives easier instead of harder. Why would we need to go all the way to Uganda to do the same, some might ask? Despite being only a 15-hour drive apart, (give or take a couple hours at the border) Jinja and Nairobi offer very different contexts for deploying edtech solutions.

Much of Kenya is very dry, with dust and heat being a major concern for electronics, both things the BRCK is designed to handle. In Uganda, with an average annual rainfall of over 150cm in the highlands (compared to Kenya’s average of 100cm, mostly concentrated near the border), water and humidity are greater concerns. The BRCK performed admirably in these conditions, with no noticeable moisture buildup in the case despite 30°C heat, 96% humidity, boat spray, and even being dropped in the floor of the raft.

(Note – the BRCK is NOT waterproof. Do NOT submerge your BRCK, leave it out in the rain, or expose it to overly wet conditions for long periods of time.)

In addition to different environmental conditions, the teachers we met in Uganda have unique goals and face different constraints. Not being educators ourselves, we built the BRCK as a platform for delivering any kind of content. While our partners at eLimu are working to deliver a custom package that conforms to the Kenyan curriculum via tablets, and Sugata Mitra’s “School in the Cloud” TED prize wish is seeking to provide access to the entirety of the web, Johnny at Hackers for Charity introduced us to Luom and David from Karamoja.org, working in northern Uganda near the border with South Sudan. Because even a 3G connection is difficult to achieve where they work, they are interested in blending online and offline content through the RACHEL platform that delivers offline versions of Wikipedia, Khan Academy, and other content packages.

We didn’t originally think of the BRCK as an offline solution, but the Karamoja.org team are excited enough about the ability to store content on the BRCK and periodically sync it with updates via WiFi from a drone or regular visits from staff to areas with a stronger signal, they made the 10-hour journey from Karamoja to Jinja to tell us what they want the BRCK to do. It was deeply humbling to see their dedication to bringing the same opportunities for learning to the children of rural Uganda that much of the rest of the world take for granted, and it’s these sorts of innovative ideas – that come from locals with years of experience working in their own communities – that drive us to design in Africa, for Africa, and to get the engineering and design team out of the office as much as possible.

Teachers Just Want to Teach

One of the primary reasons Johnny Long founded Hackers for Charity was the realization that technology offered boundless opportunities for learning, but only if teachers know how to use it. The schools in Uganda tend not to have IT departments, so he rallied the hacker community to provide their skill sets to help teachers focus on teaching, and leave the tech to the geeks. He now has a global volunteer network of programmers and hackers working to make technology simpler and easier to use.

One of the educators he introduced us to, Lisa Coggin – who helps run a number of schools north of Jinja – emphasized the need for a push-button solution to online content delivery. Teachers don’t have the time to sort out IP addresses and subnet masks, and even terms such as “dashboard” are not automatically intuitive to those working outside the tech sector. We’ve been pushing hard at BRCK to redesign the way people connect to the internet, and Lisa’s feedback on her experience with the BRCK was invaluable in steering us towards ways to further simplify our interface.

Partners in Connectivity

Ultimately, our trip to Jinja was a resounding success. Our hosts at Hackers for Charity were phenomenally generous, and we can’t thank those who took the time to share their experiences, thoughts, and hopes with us enough. We also took some time to have fun testing a couple other uses of the BRCK involving sensors and remotely operated vehicles, which we’ll get into in our next posts, but more than anything, we’re thrilled to see how excited everyone we met is about the BRCK, and to see the promise of BRCK+ED making a real difference in the future of learning in Africa.

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:

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://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!

The BRCK team sets up at the Rhino Charge 2014

We tend to be an adventurous bunch, and so it shouldn’t be surprising that Philip was the navigator for the BRCK vehicle in Kenya’s annual bushwhacking event called the Rhino Charge.

The Rhino Charge is unique, it works this way…

No one knows where the race will be until a week in advance, when a “jump off” town is named. People drive there the day before and are given a map to the camp. The night before the race, everyone is given 14 coordinates, with one as their starting point (each of the 65 cars are put at different ones, so about 5-6 at each node). The next morning at 5:30am they’re driven to their starting spot, and at 7:30am the whistle blows and they’re off. Each team’s job is to find the shortest route to all 14 spots and checkin within 10 hours. Whoever has the shortest distance between and finishes all 14 checkpoints, wins.

A couple of weeks ago the head of Rhino Charge got in touch with us to see if we’d mind setting up a few BRCK units for the competitors camp to allow people to get on WiFi there. We agreed, and soon enough Emmanuel, Jeff and myself were also going 6 hours north of Nairobi to Samburu country with Philip to setup some BRCKs.

Setting up the BRCK

It turned out that the Rhino Charge competitors camp and headquarters were about 10Km away from the nearest mobile phone tower. This meant that you could get a 3g signal, but barely, and it would fade in/out all the time. We were solving this problem at the competitors camp with the use of a directional antenna and mobile signal amp (booster).

We then got an urgent call from the head of Rhino Charge, HQ had just lost their internet and were wondering if we could switch our operations to their tent instead. Off we trundled with our gear and did the following:

The BRCK setup at the Rhino Charge HQ

• Directional antenna (by Wilson) pointed at the tower 10km away
• Wireless amp booster (by Wilson) to increase the signal strength
• 12v battery (by Brunton) to power the amp
• BRCK to transmit for WiFi
• BRCK with an ethernet cord to plug into a TP-Link 3420 to broadcast WiFi to their IT staff
• Safaricom SIM card with 32Gb of data
• Solar battery (by PowerMonkey Extreme) to charge the BRCK

Takeaways

Whenever you do field testing, there’s always a sense of relief when things work as they should. In this case, it was extremely gratifying to be able to help the Rhino Charge HQ staff on their connectivity needs, and it validated a lot of what we say about connectivity when you’re in a place with poor infrastructure. The fact that we were able to get the BRCK up and going, provide the backhaul for all of the media and stuff happening around HQ was fantastic. The only time we lost signal was for a 5-hour spot when the main Safaricom tower we were connected to got hammered by too many spectators showing up and trying to check their Facebook feed… 🙂

This does go to show that when your last line of connectivity is the mobile provider, you’re really at their mercy for what is available on their mobile tower.

Moving the power button from the top to the side was a decision we made after our Turkana expedition. This was a good move, with the dust flaps on the side, we cracked open the BRCK when we got back and there was no dust inside the case at all.

When we were struggling to get connection, we needed to know that the BRCK needed to show us that it was struggling and what the issue was. Our redesign of the lights gave us this, and it was extremely helpful this time up north.

However, there’s also some lesson’s learned and things we want to improve on the BRCK, which is good news for everyone buying a device. When the BRCK team “eats our own dogfood“, you benefit. Here’s what we found that we didn’t like, and which we’re fixing (or have already fixed):

• We need to come up with a model that defines what “abnormal BRCK behavior” is. This would be extremely useful for sending out SMS alerts especially where the device is deployed in a remote location. To put this into perspective, Jeff and Emmanuel had to periodically drive to the HQ to check on the BRCK! (like a bunch of field officers in an NGO) [Working on, will be done before shipping]
• BRCK not turning off: On the day of the setup in the field, we attempted a reboot but the BRCK wouldn’t turn off. To circumvent this, we had to pop the top open and perform a short on the BRCK board. [Fixed]
• Spotty Connectivity: Before connecting the Wilson antenna, mobile network connectivity at Rhino Charge HQ – via the BRCK -was extremely spotty; signal strength was below 22dBm. We have no way of communicating this to the user. In our opinion, the lights aren’t sufficient to communicate this simply because it’s too much information for the user to memorize. Recommendation: Communicate this info via the on-board dashboard. [Working on, will be done before shipping]
• Detection of connected network interfaces: Both the 3G and Ethernet network interfaces were connected and active but this information was not been reflected on the cloud dashboard and preferences page. [Fixed]
• Local SIM metadata: The phone number of the SIM and it’s respective mobile network wasn’t available on the cloud (and is not yet being pushed to the cloud). Having this information would have made balance top up of the local SIM less of a pain. [Working on, will be done before shipping]

Since we last updated you a month ago, a lot of great things have been happening.

Reg and Erik are on their way to Austin, speaking at SXSW on Friday. If you’re in town, do come by and talk to us. We’ll have some BRCKs with us and will show you how it’s going. You can also ask any questions and geek out with us on what you can do from the software and hardware sides to extend the BRCK core functionality.

Though Austin is always a fun place to be for SXSW, this isn’t the only reason we’re there. While the BRCK is designed and engineered in Kenya, the final assembly and manufacturing is done in the US – in Austin, TX. We’ve started our production orders, production boards are being flashed, and we’re doing regulatory testing now as well, trying to get that all accomplished quickly so we can get your BRCKs to you as fast as possible.

Some other goodies:

The BRCK Eclipse Expedition A couple months ago you might remember that the BRCK team was chasing a rare hybrid eclipse in Northern Kenya, to the shores of Lake Turkana. If you missed out on following our adventure, you can read about it on Erik’s Blog. Here’s the video of that trip:

Boxes and Dashboard Sneak Peek

Jeff Maina joined the team in February and we’re excited to have someone of his design skills on the team. Here’s a sneak peek of the box and the dashboard.

Both Jeff and Emmanuel have been crunching out a bunch of pixels and code, so that everything from the initial setup process to the dashboard work. It’s all completely responsive design, so that you can access it via your browser on a phone, tablet or computer.

The Sandstorm (@SandstormKenya) team in Kenya is making the special pouches for the BRCK backers who came in at over $300. The original design was cool, but they just came back to us this week with an even more amazing and rugged case made of canvas, leather and brass. It feels like we moved from a Landrover to a Range Rover with it!

But, when does the BRCK ship!?

This is the date we’ve been hunting as much as you. It’s been a longer road than we though, due mostly to component manufacturing issues and having to redesign things at the last minute. While we could have pushed out a basic BRCK earlier, it would not have been something that you (nor we) would have been happy with. Assuming all of the final issues lined up around components, assembly and regulatory issues, the BRCK should ship in April. We’re bending all of our time, energy, sweat and tears towards making that happen. Thank you for your patience!
