So, testing was the core motivation for building what we affectionately call “The Beast”. 120 Raspberry Pi, each with a 2.8″ Adafruit PiTFT screen, all mounted on a wood panel in a somewhat eye-pleasing format. Behind the panel, we mounted 10 USB hubs, and 10 Ethernet Switches. A Corsair CX750 power supply unit completes the beast.
The build is composed of 5 independent 24-node clusters that are unified only by the joint provision of power and networking and can operate independently if needed. They are held together with hinges, and the arrangement of the parts in the back of each section is such that the entire configuration can be folded into a tube with an almost pentagonal cross-section.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
