So I did the build a little different but overall the same outcome. Made a aluminum housing and recessed 1 inch foam inside that we water jetted the segments out of. Also a layer of powder coated black aluminum for the face. In between the aluminum and foam is a thin acrylic material to act as a diffuser and then a final clear acrylic for the face. Made it bigger. 24 inch tall numbers will 11 leds per segment… These are drag race scoreboards and each lane will get one. The computer system will send the et and mph to these boards.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
