RepRap is much more than just an open hardware project: it is a *recursive* open hardware project, (almost) capable of producing itself. That clearly places it in a different class from other systems, because it opens up the possibility of spawning huge numbers of these machines, independently of current manufacturing structures – just as GNU/Linux provides a free software framework for producing yet more free software. In truth, RepRap is not yet completely self-replicating, but there are moves afoot to achieve this. For example, the Foresight Institute, whose mission is “to ensure the beneficial implementation of nanotechnology”, is offering a Personal Manufacturing Prize to help bring this abou
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.
