We all know the common wisdom about 3D printers, that they can be used to print and replace the broken parts on the things in our lives. Here’s a fun example of that.
Morley Kert acquired a vintage punch card clock. It all seemed to work like a charm until he discovered that the printer ribbon was not actually advancing.
The makers of the device wanted to sell him the missing advancing wheel for $100. Looking at a video of the workings of the clock, he was able to reverse engineer and print a wheel for .09. Good one, Prusa i3!
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.
