Open source hardware 2009 – The definitive guide to open source hardware projects in 2009

Each year Phillip Torrone (MAKE senior editor, creative director here at Adafruit) writes a “definitive guide to open source hardware projects” for the year, 2009’s is up and it’s MASSIVE. These are all projects in which the creators have decided to completely publish all the source, schematics, firmware, software, bill of materials, parts list, drawings and “board” files to recreate the hardware – they also allow any use, including commercial. Similar to open source software like Linux, but this hardware centric.

This year there are over 125 unique projects/kits in 19 categories, up from about 60 in 2008, more than doubling the projects out there! – it’s incredible! Many are familiar with Arduino (shipping over 100,000 units, estimated) but there are many other projects just as exciting and filled with amazing communities – we think he’s captured nearly all of them in this list. You’ll see many kits from Adafruit, EMSL, SparkFun and more. Grab some hot chocolate, get comfy and spend a few hours checking out all the great projects!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Sounds like I should get into social networking a bit more!

    All open source. The Retro Adapter in particular is available as a kit or just the PCBs.

    Thanks to Lady Ada for the USBtiny programmer which got me in to AVRs!

  2. sorry about that mojo, we’ll check it out!

  3. My shield is not there either

  4. oleg – phil sent you an email, are there PCB files and license somewhere on the site? we’ve also email mojo (it seems like its gpl)

  5. Phil,


  6. What about the beagle board ( and related projects and companies like and their touchbook? I have one that was lend to me. It is in it’s infancy but i love it!
