This project started with some idle chatter with some guys I used to work with. Eric had this idea for a “slinky machine”, which would essentially become an escalator on which a slinky continuously descends. Years passed and I occasionally teased Eric about it. Eventually, I figured he’d never build it and it was fair game for me to do it.
I started with a slinky from Walmart and experimented with how high and how wide the steps needed to be for a slinky to descend. 10 cm of height and width per step seemed to be enough.
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.
