Skys Not The Limit For Arduinos In Space

Arduinos In Space could be the tagline for the two microcontroller (MCU) products that are the topic of tonights post -- Ardulab and ArduSat.

Ardulab has been completely open-sourced (from ArduLab)

First off, Ardulab. Although some may find it a skoosh misleading, SpaceRefs July 25 article about an Arduino in space is titled, "Infinity Aerospaces Ardulab Makes Building & Launching Space-Certifiable Hardware As Easy As Baking Cookies." I baked cookies tonight. Oatmeal-raisin cookies. They tasted good. Baking them was more difficult than walking across the street and buying cookies from the North Coast Co-op. But it was much less challenging than building and launching space-certified hardware. On the other hand, baking cookies was also definitely much less rewarding and interesting than launching space hardware.

Ardulab projects are intended to democratize the hardware needed to perform experiments on the International Space Station. According to the SpaceRef article,

"Today Infinity Aerospace announced the complete open-sourcing of Ardulab, the Arduino powered platform for building and launching simple experiments to the International Space Station. Previously costing space researchers, students, and experimenters between $2,000 - $3,500 per kit, anyone can now build and launch an off-the-shelf space-certifiable experiment, with the only costs being building their equipment and launching it. When it was originally conceived back in 2012, the fundamental idea behind Ardulab was to give as many people as possible the tools and information they need to be successful in space. Making Ardulab a completely open-source platform allows for all of the intellectual property to be used to its full extent. The Ardulab is a plug-n-play electronics platform with all of the necessary features and interfaces for use on the International Space Station."

Moon redwoods behind CCAT on HSU campus

It seems like Humboldt creative minds could come up with a few unique and worthwhile space station experiments. Maybe something involving redwoods in space. After all, there are already redwoods growing on the Humboldt State University (HSU) campus grown from seeds that orbited the moon in 1971. Using the Ardulab platform, the Humboldt Microcontrollers Group could help build the hardware for the experiments that get accepted by NASA (National Aeronautics and Space Administration). Or the MCU group could help organize a design competition for an Ardulab project. That might be a fun and effective way to get Humboldt students interested in learning how to design and build Arduino-powered projects and might also get them interested in space. It would just be a extra bonus if one of the Humboldt Ardulab competition projects was accepted by NASA to be sent up to the space station. Maybe the end result would be that wed have another batch of aerospace redwoods growing on the HSU campus.

The second MCU in space item for tonights post is the ArduSat. The backstory for ArduSat, designed and built by the space startup NanoSatisfi, is an intriguing one if youre interested in how a microcontroller project went from a concept to company that just received $25 million in funding. The backstory can be told as a couple guys that designing a cool, innovative and useful piece of technology in a California garage -- the Singularity Hub article "Space Exploration On The Cheap: Kickstarter Sensation NanoSatisfi Launches in 2013" says:

"NanoSatisfi is based out of a collective workspace provided by tech incubator, Lemnos Labs, and situated near the ballpark in downtown San Francisco. Upon arrival, one is greeted by a nondescript front door sporting a few haphazardly labeled buzzers...NanoSatisfi doesn’t have a buzzer—Lemnos Labs is in the garage."

ArduSat in space (from Singularity Hub)

Or the backstory can be looked at from a different perspective that seems a bit less grassroots bootstrapping, with the same Singularity Hub article explaining that:

"Singularity Hub asked Peter Platzer, co-founder of NanoSatisfi, to elaborate...Platzer began his career as a high-energy physicist at CERN [Conseil Européen pour la Recherche Nucléaire; same place the Internet was invented]...After CERN, Platzer went to Harvard to get his MBA and wound up running a $500 million quant fund on Wall Street."

The Wikipedia entry for ArduSat has a timeline for the project, but the big picture is that NanoSatisfi ran a Kickstarter campaign for the ArduSat and got over $100,000, about three times what their original funding goal was. They followed that up by raising over a million dollars more. Apparently that wasnt enough money to successfully launch that ArduSat, because they just announced today, July 29, that they have raised $25 million and changed their name from NanoSatisfi to Spire, Inc.

The Wikipedia entry described ArduSat this way:

"ArduSat is an open source, Arduino based Nanosatellite, based on the CubeSat standard. It contains a set of Arduino boards and sensors. The general public will be allowed to use these Arduinos and sensors for their own creative purposes while they are in space...ArduSat is the first open source satellite which will provide such open access to the general public to space."

If there are a few civilian space enthusiasts in Humboldt, we could pull together a complex, interesting, challenging and fun project or competition involving both Ardulab and ArduSat, two MCU-controlled projects that Humboldt people could work on. Thats one project that would truly be out of this world!

Ardusat Update 2014 15 High School Students Working With Live Arduinos In Space

This is an update on the Ardusat program which was mentioned in a July post, "Skys Not The Limit For Arduinos In Space."

Ardusat (from Kickstarter)

In an August 27 press release, Ardusat announced that their Arduino satellites program is now available globally for K-12 students and teachers. ReadWrite has a pretty good article about Ardusat and their program in the recent post titled "Soon Students Will Be Able To Control Satellites In Space." It starts out with a overview of what the program consists of:

"...Ardusat is publicly launching a program to offer "space kits" with programmable sensors that it will place in small satellites in partnership with commercial satellite company Spire. The space kits cost $2,500, but the company has made the curriculum and online resources available for free...Ardusat is running a science competition beginning Sept. 2 to provide 15 high schools with a free space kit and the opportunity to work directly with an astronaut...more than two dozen schools are currently using Ardusat, and with its public launch, the kits are available to everyone...Ardusats “space kits” contain an Arduino board—a cheap, widely available circuit board for DIY electronics projects—and multiple sensors that can be programmed to capture data on temperature, luminosity, and magnetic fields. The students can program the sensors using Arduino to test scientific hypotheses based on

Ardusat exploded view (from Kickstarter)

data that can be measured from satellite orbit—for example, finding the relationship between El Niño weather conditions and the ocean temperature near their schools...Satellite sensors will capture data and send it back to students in real-time, so classrooms can monitor how the experiment is performing each day."

The ReadWrite post also talks about one specific teacher and class thats working with the Ardusat program:

"Rachelle Romanoff is a physics and chemistry teacher...This year, Romanoff is bringing Ardusat to her 10th and 12th grade classrooms. Her AP Physics students are so excited to program sensors in space, some students enrolled in the class just for this particular project—she now has 23 students in the class...Because students can configure the sensors in real time, Romanoff says shell be using Ardusat throughout the school year. Students will write code to then send to the satellites housing their particular project. It will be crucial in helping students understand concepts like electricity and magnetic fields. The satellites will send the data back down to Earth, and students can collect and view the data on their iPads, and make graphs out of the information received from space to observe patterns or work out hypotheses...As the Ardusat programming gets more advanced, and more satellites become available for students, Ardusat envisions more technical experiments like thunderstorm tracking."

I took an AP Physics class in high school, and would have loved it if wed had access to sensors and microcontrollers (MCUs) on a satellite orbiting the earth. Can you imagine the cool projects a few creative, imaginative and determined K-12 student hackers will be doing in a few years on Ardusats system and other cube sats or other type of education or general public satellites that get launched and have this level of access. Instead of writing "Space Invaders" in BASIC and playing it on Apple II or other early PCs, theyll be programming MCUs with the Arduino IDE (integrated development environment) or other program development tools to play real-time "Orbital Space Spy," gathering real-life data in space and figuring out how to capture and package information that lets them become globally-recognized experts on their area of interest or sell information to governments or corporations.

Early breadboard circuitry for Ardusat (from ExtremeTech)

Like many other developer platforms, the truly valuable and innovative outcomes from widespread access to microcontrollers, sensors and other related satellite components that can capture or generate information or physical products in space will be things that the satellite launch companies never expected. Students, teachers and others with access to this space equipment will first do weird, fun and somewhat pointless things with the equipment, as well as activities initially envisioned by Ardusats and other organizations, such as thunderstorm tracking. True hackers rarely work on ideas suggested by someone else as being valuable or appropriate. Theyd rather work eight or twelve hours a day on

something they came up with on their own, something that fully engages them, something that no one else is doing as far as they know. Or something interesting to them that they think they can do much better than someone else.

The initial sensors in the Space Kit are listed on the Ardusat website as luminosity sensor, temperature sensor, magnetometer, ultra violet light sensor, infrared thermopile, and photoresistor. But Im guessing Ardusats have a few more sensors onboard, either for testing or for unveiling at a future time to maintain interest in the program. Early on those student hackers will also come up with additional MCUs and related components that should be added to the next satellite launched, with a clear explanation of how those MCUs and components will be used. At least one of the student hacker improvements will end up able to accomplish the purported task, but will turn out to have unexpected capabilities, either because someone figured out a new way to use the equipment or because the slightly-devious student hacker planned to use those capabilities all along but was intelligent enough to not tell people that before the equipment was launched into

space. These escapades will bring us ever closer to the day when scifi like "Space Cadet" by Robert Heinlein and "Live Free or Die" by John Ringo will be eclipsed by true life stories.

We havent reached the hockey-stick inflection point yet for democratization of the civilian aerospace sector, but programs like Ardusat are getting us a lot closer to the tipping point. If you work with STEM programs at K-12 schools, I highly recommend you consider getting involved with Ardusat. And if youre a student hacker interested in space, I recommend you start planning your personal participation in off-planet computing.

LED Lettuce The HydroTower And LED Humboldt Hydroponics

Tonights blog post has two tales of LED grow lights and the planting of a seed for a future collaborative project in the Humboldt Microcontrollers Group.

LED lettuce (from Wired.com)

On July 11, Wired had an article titled, "LED-lit indoor farm produces 10,000 lettuces a day." Because several members of the Humboldt Microcontrollers Group have expressed an interest in using microcontrollers (MCUs) for automated or indoor plant growing, the LED lettuce article caught my interest. The Wired article presents some pretty impressive statistics.

"A newly opened indoor farm in Japan has been built with LEDs that emit light at wavelengths optimal for plant growth...Its 2,300 square metres, making it the worlds largest LED-illuminated indoor farm, and is already producing 10,000 heads of lettuce per day. The LED lamps allow Shimamura to adjust the day-night cycle for the plants, allowing them to photosynthesise during the day and respire at night. Discarded produce is cut from 50 percent of the harvest on a conventional farm to ten percent, and the lettuces grow two and a half time faster...stringent climate control means that water usage is just one percent of the amount needed by outdoor fields."

I can understand that the indoor growing and carefully controlled ambient conditions would reduce the amount of water to grow plants compared to outdoors. But it seems a real stretch to believe that the LED lettuce farm only uses 1% of what would be used for an outdoor lettuce farm!

Calvin students HydroTower workshop area

The second LED grow light project took place in my hometown -- Grand Rapids, Michigan. That project was the HydroTower, the senior design project for a group of Calvin College students. The HydroTower was a fully automated hydroponic garden for home use, using an MCU for control and LED lights to enable photosynthesis and plant growth. This MCU / LED grow project popped up in a Google search after I read the LED lettuce article. Since the HydroTower happened in Grand Rapids, it seemed appropriate to find out a little more. The Calvin College alumni magazine Spark says this about the HydroTower:

"In October, the team researched hydroponics, learning about the floating, misting, and flood-and-drain (ebb-and-flow) methods of growing...their HydroTower would be constructed of a 20-by-32-by-32 inch base unit, to house the electronics and plumbing, and two open growing levels, each measuring 24 by 32 by 32 inches. The unit would operate on an ebb-and-flow system, and it would irrigate the plants and dispense nutrients automatically...In November, Team HydroTower broke the project into components, and each student engineer took one. DeKock would construct the

tower. Kirkman would engineer the water and piping. Vonk would create the LED system, using only red and blue lights because those are the only colors of the spectrum that plants absorb. Meyer would program the microcontroller that controls the LED lighting, the pump and valves, and the touch-screen user interface. And Eelkema would create the pH and electroconductivity sensors that handle nutrient control—a system, the team emphasized, that sets HydroTower apart from other hydroponic farms. “The sensors would input into a microcontroller, which would then use algorithms to decide which nutrients need to be replenished,” Eelkema explained. “The only problem with that is the biology and chemistry research is far more advanced than we have time to cover. Right now I am shooting for a best guess that I know won’t kill the plants."

The Calvin College students project website gives this final update on the project:

"All through April and the first week of May Team HydroTower worked...to finish the prototype. The month of April saw the addition of our second growing level and some new plants. Other major accomplishments made before Design Night were completion of the pH and EC sensors, a working User Interface on the touchscreen...On May 7th the Engineering department held their annual Senior Design Open House where the team answered questions and took comments about the HydroTower. Later that evening the team gave a presentation detailing some of the work and challenges they faced during the past year...HydroTower is a finalist in the IEEE Presidents Change the World Competition. The project has been selected as one of 15 finalist entries and the top three winners will be announced at the end of May."

Humboldt Laser Harp v.1.0 nearly finished

It seems like the first collaborative project from the Humboldt Microcontrollers Group, the Humboldt Laser Harp v.1.0 (HLH), is well under way. Ed Smith said today that the HLH was being played by his kids in his kitchen. We will no doubt be working on improvements to HLH v.1.0, and at some point will start planning for v.2.0.

But this seems like a good time to plant a seed for another MCU group project. And a project involving some type of hydroponics and LEDs seems like a good target. Ill be reaching out to a few people to see if they want to work on that kind of a project.
