This was an extremely fun job I did for an organization called Brazil Against Violence.  Among some other signage, they wanted a statistic counting clock.  What the heck is that!?  It’s a digital clock, that keeps track of different metrics, based on statistics gathered by an organization called Fundo Brazil.

The most fun parts were discovering how 7 segment displays work in terms of software, and implementing my own using Neopixels and Arduino.  Designing the the physical part was fun too.  I used the laser cutter to make baffling layers that sit between the LEDs and the front surface.
