I'm building a basic thermometer that displays the temperature on 4 seven segment LEDs. I want to put the circuit in a box with a clear plastic lid.
I'll mount the LEDs on the PCB around the other components, and fix this flat against the base of the box so the LEDs shine up through the clear plastic lid.
My question is how can I hide the electronics (i.e. the MCU, temp sensor, resistors, etc) but still be able to see the LED display, by some how darkening the clear plastic lid, and make it look more professional?
Alternatively, can you get enclosures with a translucent lid? I've searched but can't find any.
