How the Internet of Things Can Help Save Our Rivers

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.

Sensor dip

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.

Campfire

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.

Expedition 2014 – Exploring Edtech on the Water

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!

Hybrid Eclispe, live from Lake Turkana, Kenya

We hear a lot about how the internet makes the world flat. But in practice the topography is more diverse.

While good internet access is growing all over the world, there are still 3 billion people in the world who don’t even have the opportunity to access broadband internet, let alone the financial or infrastructure means to do so. BRCK was developed, in part, to lift up the availability and quality of internet access for people all over the world. Shortening the distance between remote regions of the world and places more familiar with the internet is to everyone’s benefit. Both sides have incredible things to share and gain from better access to the web.

On November 3rd, we’ll be using a BRCK to show you something amazing from one of the most remote part of the world. We’ll be streaming a stunning Hybrid Solar Eclipse out to the world live from Lake Turkana in the far North West of Kenya. People all over the world will get to see this incredible event from their own homes. The world will get a little flatter.

In addition to being a prime location for viewing the eclipse, Lake Turkana is about as remote as it gets. You may have heard us say “If it works in Africa, it’ll work anywhere”? Well, if it works in Turkana, it’ll work in Africa. The journey will be two days from Nairobi on mostly dirt roads. We’ll be using the adventure to pressure test the BRCK ahead of production in January, and have a little for with the internet in a very remote location.

We’ll be spending the next week prepping and then heading out on the 31st.

You can keep up with us on Twitter (#brckeclipse), here on our blog, and also at our special site for the event: http://brck.com/eclipse.

BRCK shirts out in the world

Here’s the lovely Chirstopher Neu of Tech Change (@neuguy) sporting his BRCK shirt. If you love your shirt(s) tweet them to @brcknet and we’ll share them on our tumblr.

Share the love, spread the Internet of Things revolution.

Case Design Finalized

We keep saying that the BRCK Engineering team is working feverishly to meet our kickstarter deadlines and today we get to show you what some of the fuss has been about.

print side

This is a 3D print of the final design for the BRCK’s case, careful observers will note that it’s a bit taller and the port covers don’t come all the way to the base anymore. 3D printing is an amazing tool in modern product development and it’s super fun, but it’s not perfect. The process is a constant compromise between speed, durability, and accuracy. You never get to have all three, but on the other hand, nothing else gives you the same feedback in such little time.

Most of our prints in this process have been done at Incept3D on an Objet printer. Objet prints are fairly brittle: a little too much force and they snap or even shatter. Not the sort of situation one typically thinks of when your making a device made in and for Africa. But the upside is, if you can make a rugged and durable case from an Objet Printer, then your final case will be that much the stronger for it!

You’ll notice the vertical ribbing on the inside of the main case comes up and actually locks into the top plate making it almost function as a solid block. We’re especially proud of some of the little features like that.

Now that we’ve gotten to a point were we can throw brittle prints around the room with little concern, we’re just about ready to cut our injection mold tools and make the real things!
