Here at Adafruit, we are big fans of Kickstarter and crowd funding of open source projects. Crowd funding is a great way for a small open source shop to take a dream and make it a reality. Crowd funding is especially valuable with open source electronics and hardware because there is such a huge discount when buying components in large quantities. Recently, I have become obsessed with combing through Kickstarter and looking for great open source projects to invest my money into. Here are the three latest projects I have funded, and I think you will like them as well.
First off is a GPS tracking device developed by DSS Circuits. DSS Circuits have been around for quite some time, but you have more than likely never heard of them, so go check them out. They make some really great open source hardware. Their latest project is a GPS tracking device. This is their first project to make it onto Kickstarter, and the device looks really great. Here is what $126 will buy you:
- GPS – An ultra sensitive -165dBm receiver with on board passive antenna that can be configured to a 10Hz update rate.
- GSM – SIM900 Quad band GSM module to connect to the GSM cellular network. Unlocked SIM card necessary (not included).
- USB Battery charger – charge rate set to 500mA by way of mini USB connector. Can be charged directly from most computers.
- Lipo Fuel Gauge – MAX17043 single cell lithium polymer fuel gauge.
- Accelerometer – BMA250 Triple axis +/-2 to +/-16g 10 bit accelerometer.
- Microcontroller – ATMega328p running at 3.3v 8MHz with the Arduino bootloader installed
- Power,GND,I2C,SPI,4 Analog/Digital and 1 digital IO pin headers
- Optional underside coin cell battery (CR1225) backup holder to retain GPS memory if main battery is disconnected
Next up is the DRONE Smart Controller by Evolution Controllers. This beautiful looking controller is being sold as an easy way to connect to your iOS or Android device to play games. The internals are going to be Arduino friendly, so the main reason I backed this project is because I would love to use this little controller to operate an Arduino robot. The complete project is open source, and here is what they will make available:
- PCB board/layout so that you could make your own board if you want to perform a major overhaul of the electronics.
- Atmel ICSP Programming Connector
- 16 pin “breakout” header will allow you to access all the pins including the X,Y of the Joystick. This ribbon cable can be routed out the front of the controller so that you can use whatever buttons or other input mechanism you want.
- The Drone Programming Library will have utility methods and constant definitions that will make writing your own firmware even easier.
- The official Drone Firmware will be available as an Arduino Sketch.
- For those that are less technical but want to try out the latest we will make a firmware update tool available

The third project I am backing is the MakerSlide. This is a project that has already been successful on Kickstarter, but I missed out on it the first time. For round two they have gone to Inventables for their crowd funding. What is the MakerSlide? The MakerSlide is an open source aluminum extrusion with two special rails for wheels to roll on. What would you use this for?
This component is interesting for people designing CNC machines because it acts as the structural support and the linear bearing system. The biggest design, cost and fabrication hurdles in a new CNC machine design are the linear bearings. There are a lot of commercial and DIY solutions out there, but none support an easy, low cost and rapid fabrication philosophy.
The basic bearing concept is not new. The inventor of the MakerSlide, Bart Dring, had used it for years in his own designs and many high end commercial systems use it. This system is traditionally called a V wheel running on V rail. The problem with the commercial systems is that they are expensive, require a lot of accurate fabrication to integrate, and don’t seamlessly integrate into standard extrusion systems. The MakerSlide solves all three of these issues.
MakerSlide is a V rail integrated into a standard extrusion profile. If you are working on a CNC system like a 3D printer, CNC Mill, or CNC Router this MakerSlide might be the right structural support and linear motion system for you.
I plan on using the MakerSlide in a time-lapse photography rig, but the opportunities of it are endless. Click here if you want to learn more or back the project.
Backing any of these projects is a lot of fun. Not only do you support open source hardware or help make someone’s dream a reality, but you actually get a real product when all is said and done. I would love to hear about any other open source crowd funding projects that you are interested in. Share them in the comments!
