UltraWide Retro Computer Terminal

This is a small desktop computer terminal designed around an ultrawide 8.8″ 1920 x 480 LCD, with a rather exotic 4:1 aspect ratio. As this exceeds my 3D printer bed size, I had to figure out a way to split the design in two parts, and how to assemble them effectively. The design allows to run it with a Raspberry Pi 4 or a Jetson Nano 2GB; the mounting of the SBC is quite modular.

It uses M3 standoffs and nuts (I used nylon), and custom printed parts to hold it all. The standoffs are pressure fitted into the print, making it very easy to swap SBC, and also very easy to stack new components.

The design also makes it easy to mount the mipi hdmi board behind the LCD, keeping the build tidy. You will need hdmi ribbon cables with angled connectors, which you can easily find in AliExpress or similar sites.

The build also offers an optional mount for a particular USB speaker, that has worked ok for me, also found in AliExpress.

I printed this on an Ender 3. It barely fits on a 220
