Jaymes Dec shared a project-in-progress for the project demo night at ITP Camp 2014. He built a clock display using a set of laser cut number rollers (with bare-wire numbers for each position) and brought the numbers up to temperature by feeding power via springs rubbing against contacts along the side of the rollers as handy make-do brushes. Draped over the whole case was a piece of thermochromatic cloth — where the ghostly glowing numbers would shimmer into focus and then vanish.
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.
