How to Build a Simple 3D Printed Arduino Animatronic Eye Mechanism

Here's how I build my simplified 3D printed arduino animatronic eye mechanism. This is a good option if you'd like to try out some DIY arduino robotics but don't necessarily have access to certain specialist hobby components, high-quality 3D printing or workshop tools.

ABS is good for making realistic eyes but not necessary. - 6x SG90 Micro Servos: https://amzn.to/3TEXjpR - Various M2 and M3 screws although any screws roughly that size should work ok. A kit like this: https://amzn.to/2JOafVQ should cover you. - Arduino: This design was tested using a genuine Uno, but it's likely that any board which has SDA/SCL pins, 3 analogue inputs and a digital input will work. Arduino Uno: https://amzn.to/2JTs1Hs - 16-Channel Servo Driver: https://amzn.to/4cijGsg - 5V Power Supply, around 4A is more than enough: https://amzn.to/49Wqni0 - A female DC power jack to match your power supply, to be soldered to the servo driver board: https://amzn.to/43j0KFC - *2* axis Joystick: https://amzn.to/2NR4JnY - Potentiometer (optional): https://amzn.to/2r0nADS - Push-to-make switch (Some joysticks have this built in, but its easier to control when it’s separate: https://amzn.to/32Wnvyh ) - 10k Resistor: https://amzn.to/374seRU - Jumper cables: https://amzn.to/2NToCuw - *6** MG90s servos: https://amzn.to/4afx4vv Also, a pin vice hand drill might be useful for adjusting hole sizes: https://amzn.to/4afx7rb
