Need a crank for a rotary encoder? Here’s a print-in-place model that features a hinged arm and free-rotating handle. The pieces can not be disassembled. It’s just one part that prints in about 20 minutes. Press fits over any flat nose rotary encoder, for those times where you need a cranky crank!
Fusion 360 model included with accompanying STEP file. User parameters are setup for tolerances, length, shaft diameter etc. Gap is set to 0.4mm in STL file. Check out the source for your own tweaks!
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.
