My previous instructable was an attempt to make an eye mechanism that was as accessible as possible to as many people as possible, but in this project I wanted to design something that was more of a middle-ground between accessibility and quality. This design features some more speciality parts such as servo ball-links and pushrods but it’s still quite easy to build. It uses a mechanism design which is commonly used in professional eye mechanisms, but it circumvents any machining by using parts that are designed for 3D printing. Compared to my previous design, it is much more compact, robust, and a little lighter.
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.
