The 2011 Open Hardware Summit was held this week in New York City. We were fortunate enough to be able to design the badges for the event, which are pictured above.
Naturally, the badge itself is an example of open source hardware. It’s constructed as an extra-thick circuit board, in the shape of the Open Source Hardware logo, with plated gold finish. It was made with our usual open source toolchain, including Inkscape and gEDA/PCB, and the design files are hosted at the Evil Mad Science Wiki.
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, 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.
