I've wanted to build a MAME cabinet for a long time and finally got started. I intend it to run mostly MAME, atari800, and stella. It'll be powered by a Raspberry Pi and use a 19" 1280x1024 LCD monitor. It's going to have a modular panel, like the one Rick Reynolds (here on AtariAge) built, and another one with smaller component panels.
It's going to be styled like a Tempest cab; I have a sketchup based on the original dimensions, but modified a bit to make it a bit easier to cut out and build. The control panel is going to be 24" wide, and will have a bunch of smaller panels that can be swapped in and out.
There are panels with 4", 5" and 7" widths, and this is a mockup of the control panel section because I wanted to experiment since I'm still not quite sure what the best way to lock the panels down securely will be:
Each of the little panels has a quarter inch plywood tongue on the bottom that locks into a groove on the front of the cabinet, and another tongue at the back that I think I'll try to lock down with a hinged board that will lock into place, holding the top of the panels. Here's a view with one of the panels removed:
and a closeup of the two panels I've built so far:
So, I'm sure this build will take a while, but maybe by posting my progress it will help keep me motivated.
