Hi everyone, Mike over at ArcadeCab.com suggested that I stop by and sign up for the message board.
Being the "newbie", I guess the best way for me to introduce myself is to show you guys the projects I have built so far. I think this will keep me "on topic" for this topic area as well...

I built my first cabinet last year. It's a full sized unit based off some plans that I picked up off the Internet. It's a pretty basic machine with an AMD 1300 processor that runs ADVMame/ADVMenu... The monitor is vertically mounted.
Shortly after that I built this jukebox from a set of plans from MameRoom Designs. Again, I used an AMD 1300 processor, but this time I put in a 100 gb hard drive. I used SK Jukebox (GREAT PROGRAM!) to categorize all the music. This unit has a fully functioning Bill Validator that accepts $1, $5, $10, & $20's...
My latest project is a bartop unit that I built based off of the Oscar Bartop & ArcadeCab Bartop designs. It has a 17" flat panel LCD monitor monted horizontally. To keep it simple, I am using MAME32 with this one.
I have all of the cabinet plans loaded into a CAD program and everything is cut using an OMAX WaterJet. Because its computer controlled the pieces come out perfect every time. Even the control panel holes are cut. Its almost the same as using a CNC machine except it can't do angles, so there is a little hand finish work required to bevel the back pieces and for the routed bits, but all of the major pieces are ready for assembly literally in 10 minutes. (This is a HUGE time saver) From there its just standard stuff with putting in all the internals and wiring in the control panel.
My next set of plans that I am in the process of finalizing will be a full sized machine with a custom control panel two joysticks, trackball, detachable steering wheel & a spinner.
My wife has complained a few times that the black red color scheme of the machines don't match any of the furniture, so this one will be an oak finish and all black trim. This should match the color scheme of the family room a little better.
So that's my intro... I'll keep you all up to date as I begin the next project
