Robot Companion Pendant

First attempt at building a small companion in pendant form so it can be worn easily. Very janky as it was slapped together in about 3 days

Story

Disclaimer: Very janky as this device was thrown together in 3 days with no real plan. Also, more pictures and videos areto come.

I built this pendant for my birthday. I am tired of living in a world that is not as magical as it could be. So I have decided to help be the change I want to see and make my world of tomorrow today. It initially started off as a simple electronic badge that would just be able to change the image it displayed, however during the making process something magical happened.

As I started drawing sprites and was staring at the black LED screen I noticed a single eye staring back. It was at that moment I knew that this was no longer a simple badge but something much more.

Embedded in the device is the initial spark of a being that is slowly growing, observing and learning. I expect its shape to go through many changes over time and its powers to grow as well.

This pendant was built from components that I had lying around and or easy access to at work. This design currently seems to meet the requirements needed to keep this spark contained however it will not be suitable for long and will need to be upgraded. it will definitely need more Flash space, possible Bluetooth connectivity, a bigger display and a less bulky form factor.
