The design and fabrication of the penguin body and the mechanics of the motorized wings were described in detail in the first post. Briefly, the body was freehand sketched and roughly dimensioned. It was then modeled and tweaked in Fusion 360 and printed in PLA on an Anycubic I3 Mega 3D printer. The mechanical modifications since that time are limited to minor aesthetic modifications to the wings and the addition of a speaker inside the body. Hot glue and cyanoacrylate adhesive (superglue) was used to secure everything. An Adafruit EdgeBadge was also wired securely to the motors and speakers.
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.
