You don’t need to have mechanical innards to roll around like BB-8. Do what Imgur user jtoeman did and construct the droid from paper mache. He used an emoji beach ball for the body — he had to use something big enough to fit around his frame so small balloons wouldn’t do the trick. He then used paper mache techniques. It took a long time to cover a 56″ ball completely. He used large strips of paper, but even with that adjustment, the process was still time consuming. He used a yoga ball base for BB-8’s head. He had to use a space heater to help with drying time. A couple in-progress photos:
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.
