NEW GUIDE: John Park’s Ninja Timer:Giant 7-Segment Display @adafruit @johnedgarpark #adafruit

Here’s a new guide on how to make a huge seven segment display timer for a ninja warrior obstacle course! Or, any other need you have for a super big timer or clock. Segments are made from NeoPixel strips, diffused through acrylic, and controlled via massive arcade buttons and an Arduino!

Here it is in action at the UNAA (United Ninja Athlete Association) competition at Train Yard 317 being used to time each run.
