DaOld Man:
I would ground the metal plate.
Attach a wire to the plate and take it all the way back to the power entry ground.
On one of my builds I did not ground the coin door. Later on (probably during winter months) the keywiz quit working. Im pretty sure it was due to static from the coin door. My nephew who I built the cab for, kept it in a carpeted room. We all know what that can do (ever get a spark when touching the door knob after dragging your feet across the carpet?)
Good work BadMouth. I like the drink holder, but is there any chance of getting your fingers pinched by the CP sliding and catching your fingers between it and the glass?

Edit: attaching the plate via a wire to the power supply should be ok. The power supply case should be the same as the power entry ground. (As long as the power supply is properly plugged in.)

Guess I better ground the coin door too then. :lol
Maybe the lamp sockets are grounding it, but I'll run a wire just in case.
It will actually look cleaner to run from the control plate to the door, then to the PSU.

Hadn't really thought about it as it's not automated. After your comment though, I attempted to pinch my fingers under it and couldn't.
Everything is smooth and there isn't much of a gap. It just pushes my fingers out of the way, even up over the lip on the cupholder.
I'd have to have my hand down in the drink holder and then push the CP into it.
Even trying that, the CP doesn't fly back and forth. It has a fair bit of resistance and moves slow and steady (no bearings).
Nothing to worry about. Very few people will play on this cab but myself. ;D

BadMouth:
Doesn't look like much progress, but I've managed to make a full size 300dpi version of the CP in Paint.net
I don't know how to use illustrator and don't want to take the time to learn right now.
The goal with this is to get the button locations perfect and then turn the layers over to a pro so they can make a nicer version.
There is a drilling template layer with the centers marked and an outline layer that has both centers and outlines marked.

I'm going for kind of a candy cab/MVS mashup. I'd like something brighter and more modern in the background in place of the stripes. Might leave that up to the final graphic designer. I'm sure they'll have some tricks for abstract backgrounds. The grey thing in the middle is a spinner knob. Not sure I'll add one, but I want the artwork to allow for it just in case.

The joystick and main button locations are set in stone. I've done extensive testing (playing) on the cab and that is just where they belong.

I can't make up my mind about the start buttons though. :-\
I like the symetrical look of them on the edges, but it feels more comfortable when using the machine to have them at a point midway between the joystick and action buttons. If put there, I'm not sure what to do with the leftover space to the right of player 2 start.
Opinions?

I keep coming back to the same boring marquee.

I think with the same abstract background as the CP and some shading on the letters, it could look good.

BadMouth:
Maybe if I bump the thread, I'll get back to work on it.....

Was saving this until it was finished, but that doesn't seem to be coming anytime soon.

Music by eds1275, animation by PixelHugger:

Original for reference:

eds1275 made three different versions with slightly different music.
There is this synth one, a fancy lead guitar one, and a gritty sounding guitar one.
They all rock!

PixelHugger is creating the marquee and control panel artwork, but I told him not to be in a hurry.

Next on the to do list:

> Build circuit for 4/8 way switching (accomplished by adjusting brightness of IR leds in optical switches)

> Cut out yokes for rotary sticks and figure out how to keep open bore encoder perpendicular to shaft.

It is playable and is awesome to play on, but that's not what is slowing progress.
The problem is that I have too many projects and just when I get them down to something manageable, I add more.
I'm also horrendously non-productive when I force myself to work on something when I'm not in the mood.

EDIT: To go along with the Evolution part, we're using DNA strands in the background.
This is just a draft, the SNK and EVS logos will receive some kind of embellishment.
Much better than my plain red version.

Chris John Hunter:
Whoop Whoop! This is bloody awesome BadMouth. And this is the first great cab I have seen on here without the 'US Fridge' syndrome.

:applaud: - I really like your genre menus too they look the dogs bollocks (British compliment)

Can you get your arse in gear cos I can't wait to see what this turns out like!!!

:cheers:
