A family built a robot project, faced challenges with a display pinout, and later miniaturized it into an Altoids tin.
They received a robot kit from a booth at MIT Swapfest.
They used an Arduino Nano and a solderable breadboard to reduce size.
They struggled to fit all components into an Altoids tin.

It all started when I took him to MIT Swapfest for the first time. We saw an assembled robot from a couple’s booth; later we learned that it was from a kit. It was built by their daughter many years ago. After realizing I had come with my son, they gave us the robot for free. We also picked up a used ThinkPad laptop at a very reasonable price, which we used for the project.
As any curious mind would, we disassembled the robot. Noticing that we were missing the control, we wanted to see which parts we could reuse. We took the 128x64 display off. But we couldn’t find the pinout for the display. We tried using AI, but it hallucinated so badly that it gave us a 20-pin pinout when the display only has 10 pins.
