Overview
The Brass Problem.
The decision to design MO completely out of brass wire was made to put the internal electronics of MO on display. Most electronic devices hide the internal components, killing the curiosity of interested individuals. A 1.51 inch transparent OLED display is used to show eye expressions and ultimately increase the playfull, lifelike nature of MO. The ESP32 WROOM hosts a wifi network that can be used to drive MO and change his facial expressions.
The challenge
Electrical and Machanical Design Considerations
MO is build completely of brass wire. This creates a difficult problem when it comes to wiring. The frame is grounded, and all PCB's are soldered to the frame using ground conections. Logic wiring must float from point to point as to not ground out if they touch the frame.
