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 NiƱo 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.

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.

Daemons Car duino Tracker

,
Daemon by Daniel Suarez is an excellent book for most people who are interested in microcontrollers (MCUs), and Im currently in the middle of re-reading it. The MCU project in todays post, OpenTracker v2, is something that would have been right at home in Daemon.

OpenTracker (well drop the v2 suffix for the rest of this post) is an Arduino-based GPS / GLONASS vehicle tracker. The August 21 article in Electronics Weekly gives an overview of OpenTracker and mentions a couple use cases.
"This one could of interest to a Gadget Master looking to track moving objects, such as a vehicle. Want to monitor your elderly parent, perhaps, or keep an eye on your son or daughter’s first driving adventures...The people behind it, Tigal, are raising funds on the Indiegogo crowd-funding website...it’s actually the second version of the firm’s open source GPS/GLONASS vehicle tracking system...As well as tracking single or multiple vehicles, it also monitors the speed and altitude of the objects...The Arduino Due compatible module has an Atmel SAM3A8C ARM controller, a Quectel M95 GSM/GPRS modem and a Quectel L76 GPS/GLONASS module..."
OpenTracker v1
TIGAL just completed their Indiegogo effort to fund the development and launch of the second version of this moving object tracking device. Their Indiegogo campaign raised only €3,319 toward their funding goal of €50,000, so the new version of OpenTracker didnt get quick or strong uptake in the maker community or the general public. Because the Indiegogo effort was a flexible funding project, TIGAL, the developer of OpenTracker, keeps the money pledged. Also, TIGAL is an established Austrian company that sells the first version of OpenTracker online, as well as other products. The first version can be found online for €118.80 including 20% VAT.

Based on the online description of their company, TIGAL will likely continue development of the trackers second version in spite of not reaching their crowdfunding goal. It will likely take longer for the second version to become available, so if youre interested in this open source  moving object tracker, you should probably just buy the first version to learn on while waiting for the second one to appear. If you do interesting hacks with v1, TIGAL might want to have you be a beta tester for v2. Their website describes the company this way:
"TIGAL is a...international distributor and manufacturer of...innovative technological products.  TIGAL’s product line includes embedded Linux/Windows CE devices, M2M solutions, wireless devices, CAE/CAD, development systems and compilers, professional programmers, measurement tools, LCD and OLED displays and display modules with and without touch screen functionality, and speech recognition development tools and systems. TIGAL is also leading several OEM projects with its international partners...in the fields of SMS and MMS messaging, Voice Recognition and Linux-based development tools and embedded hardware."
If youre considering buying or building a GPS tracker, you might also want to look at a few of the
other open source trackers. I didnt do in-depth research to find out which have the best reputation, but here are a few links to get you started:
GeogramONE board
  1. GeogramONE (originally released as DSS Open Source Tracking Device on Kickstarter) -- $120.00 -- "The Geogram ONE is an open source tracking device based off the Arduino platform.  After a successful Kickstarter campaign, several hiccups in the manufacturing and assembly process, were proud to announce the Geogram ONE is finally available for sale. Were selling the bare bones board here for development, however to take full advantage of its capabilites youll still need...accessories...The board also comes preloaded with firmware to use as a tracking device.  Communication is handled simply by send an SMS from your smart phone."
  2. RuuviTracker -- "...an open-source, electronic global positioning device as well as free
    RuuviTracker Rev C PCBs
    software. Our GSM- and GPS/GLONASS/Galileo-enabled tracking system can be used for various different tasks...it can be used to track your hunting dog, it can become your vehicles alarm system, a portable weather station, a security system for your children...The device itself will be an affordable, water-proof, robust, high-quality and state-of-the-art product...We have, for example: 168MHz ARM Cortex-M4, GSM, GPS, GLONASS, Galileo, accelerometer, microSD, microphone, speaker etc. The device draws only few microamps during sleep, so even a small battery might last for several years. Additionally, our accelerometer is able to wake-up the device when its touched
    ." Heres a link to the project status page on their wiki. They appear to have completed a Rev C PCB (printed circuit board) for their tracker in June 2014. 
  3. GPS Cookie (funded with a Kickstarter project in 2013) -- $89.00 -- Overview from
    GPS Cookie
    CNET
    : "The GPS Cookie runs on two AAA batteries and records data onto a microSD card you supply. It records data, time, and location to track your routes, letting you build up a history of your movements. That data can then be imported into Google Earth so you can visualize your travels. The idea behind the gadget is that you just carry it around and not worry about it until you upload the data to Google Earth and see your information. This could come in handy for travel abroad so youll be able to locate that out-of-the-way Parisian cafe later. It can also be used to track bike routes, commutes, or just about any travel adventure."
  4. Adafruit Ultimate GPS on the Raspberry Pi -- From Martin OHanlons blog post about this Adafruit GPS tracker: "I got myself one of adafruits ultimate GPS breakout boards as I want to experiment with capturing GPS data in my car projects.  Its a seriously good bit of
    Adafruit Ultimate GPS on Raspberry Pi
    kit and if you looking for a GPS module you could do a lot worse than this.  They also have an excellent tutorial on setting it up with the raspberry pi...I used the raspberry pis on board UART to connect to the GPS module, Adafruit advocate using a USB to serial device but that didnt suit my needs (I need the USB for other things). I also create a GPSController class in python to allow me to communicate with the module easily
    ."
Ive never done a maker project with GPS tracking, but it appears there are a number of options for doing that with open source designs. If you want to track your child, your parent or a potentially wayward or nefarious client (I have no idea as to the legalities of any of those activities and IANAL) or if you want to clearly understand how someone might be tracking you, this post should at least point you in the right direction...
