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.
