What is the DCZia 2018 Badge

This year we want to keep up with the tradition of our past badge which contained mechanical keyswitches on it to give it a retro look and feel. We decided on a 4x4 grid of mechanical keyswitches with an rgb led underneath and transparent keycaps to make an interactive display of sorts.

We also will be adding a small oled at the top center of the badge for more ovbious visual output. Board will be powered by an ESP32 and will talk BTLE and possibly Wi-Fi if we can find something cool to do with it.
