This page is mostly a copy of my Thingiverse entry here, but with extra observations: http://www.thingiverse.com/thing:25772 Before paper was commonplace, the method for keeping your thoughts in order was the wax tablet. They’re surprisingly easy to write on, and are capable of capturing almost the same level of detail as pen and paper. If you make a mistake you can use your finger or the rounded end of your stylus and smooth the wax back to blank again.
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.
