I’ve written about open source hardware (OSHW) a few times before. Like this and this. I’ve understood open source software for quite some time and over the last few years have been starting to get what open source hardware is all about. It is different than open source software.
With software, your tangible product is essentially intangible. Your acquisition and distribution of an open source project can be virtually free. Not so with hardware. Someone has to physically build something, which costs time and money in parts and labor. Really though, all that means is the proliferation of an open source hardware product just takes a little longer. If you look at it as the design being open source more than the actual product, then it gets to be more and more similar to software.
While open source software has moved into real business, hardware is still more closely associated with the hobbyist community. That is changing though. Ti’s Beagleboard is serious stuff from a serious company. Some of the hobbyist catering OSHW companies are growing to or have grown to the point of being serious businesses (Adafruit, Sparkfun).
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 code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
