so, here are a couple of shots of the control panel. I didn't think to take pictures of the construction process, but documenting that is probably best left until I figure out what I'm doing.

as it stands, I only have the control panel assembled, wired, and working, but I am pleased with the results so far. it was made from MDF and assembled it a few days ago at my folks' place with my dad's help. I spent a few hours priming and painting this past Saturday, which incidentally is not a bad way to spend shaking a hangover, and then yesterday, I mounted and wired the joysticks and buttons.
my next steps are to 1) do some field research on real-life arcade cabinets, 2) build my own cabinet, and finally, 3) put together an adequate box for running MAME. stay tuned as I will post updates from time to time along the way.
for what it's worth, I highly recommend the Happ 8-way competition joystick for anyone who is thinking about heading down this road.
