Front Panel Instruction Indicators - Cardboard Prototype

It is pretty rough, but this cardboard prototype of the "Instruction Indicators" panel will be pretty useful when I am working on control logic. I am working on the computer instructions / operations, and this will greatly speed development and allow easy confirmation that the control signals are correct.

Making a prototype was also helpful to identify some issues with the current design, including how impossibly bright the LEDs are. The illuminated LED in the above photo has two layers of opaque plastic covering it. I will be experimenting with dips and coating in the coming weeks, but the best option may be to power the LEDS from a separate 3-volt system to improve the lifespan of the LEDs.
