As a learning experience, I had a metal chassis that my friend in the news helicopter business had brought home.. and it had the right basic shape..
so I made a 47% scale Star Wars.-Two foot 4, just about Yoda size..a "Yodacade", from the Dagobah arcade.
(I know, Yoda wasn't in the first movie.. But I'm not going to start over and make it a ESB conversion..)

Recycling to its extreme. Two junked 9" trinitrons gutted and modified to fit _safely_ in there (well, as safe as say, a arcade monitor)
And lots of little bits from varied regular games (switches, harness wires) and just $5 of wood and a $7 tiny flourescent tube from K-Mart.
(That's a lighted button recycled from my Triviai Whiz parts with coin slot art inserted into it-
I may make a working coin switch from a spare- it would have to accept dimes, though..
Most expensive part, not surprisingly, is the art, but it was much cheaper than the real ones. I have all the bits, just waiting utnil I get the bezel area fabricated.
It really helps having a color print place that isn't overly concerned over copyright issues.
I've used a lot of information from the forums here for methods to this madness.. and again, easier to make mistakes on a scale model than the real thing.
Still working on it, got to make the 3-D monitor bezel from pipes and things, and figure out how to do the marquee area correctly. Even stereo speakers, gutted from
some PC amplified speakers. Currently it's just using the video inputs, but the plan is either a Mame Mini ITX PC or a x-box. The PC would fit better,
I don't think there's room for the x-box!
Then there's the issue of the controller. That joystick is not the finished product. I've got the parts to make a regular yoke, then a mini..
but 47% scale isn't going to be very playable, so I may hook up the regular-size equivalent that allows play external of the cabinet. Weird, yes.
I have more the details, methods and art bits I used to make it on me
website.There was one modification to fit the proportions of the cabinet I'm using. Can you spot it?
