Anyone who owned a Radio Shack Armatron robotic arm in the 80s likely has fond memories of it. I still have mine, with all of the accessories, and it still works!
In this 8-Bit Guy video, he restores one that he bought online for $20. During the restoration, he shares an invaluable tip. This thing is filled with gears. To keep them all straight for reassembly, he photographed each step of the disassembly. To reassemble, he just looked at the pics in reverse order.
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.
