I made another wee thing at the weekend.
its a "mini arcade cabinet marquee" styled lamp.

its is controlled by 3 toggle switches that turn on / off the RGB components of the LEDS in it.

the end panels are held in place with magnets so they can be taken off and the front game panel can be removed and swapped out for another game.

its all powered off a standard usb cable.

A collage of four nighttime shots showing the mini arcade cabinet marquee lamp lit up in different colors — white, red, blue, and green. Each lighting mode creates a unique retro glow, highlighting the "Asteroids" game panel.

the second image is a slightly different earlier version showing the outrun panel instead of the asteroids.

Retro Gerry

theres light leak at the edge of the front panel so might put a defuser over LEDs to help that, maybe line the inside panels with some reflective foil to prevent all the light leaking through the top bottom and side panels.

I have a few other components laying around and was thinking of doing one with a ESP32 in it and controlling lights using WLED.

another idea is to switch out the toggle switches for rotary potentiometers and give more control on RGB values rather than simply on off.

I have several protoypes of the design laying around. mostly panels of various designs I wanted to test. So i could probalby make a few of these.
I even have an end panel thats got a cavity and cover to embed a zero W. so the entire mini marquee becomes a retro gaming mini cab of sorts when plugged into a monitor and using a wireless gamepad. I toyed with putting RFID chips into the back of the front panel to "load" the games into the Pi, but never did. but the gaming version worked.
