NEO GEO Evolution (EVS-1) - Experimenting with DIY trackball

NovaMatrix LINX marquee light from groovygamegear:
(I wanted the light to eminate from a line down the center)

I explored a few different options for the air intake, but settled on having it in the bottom of the cab instead of the back.
Partly to keep light from entering through the fan, partly because I didn't want an area of dead air in the bottom of the cab that wasn't getting any airflow. Since it would be sucking dust bunnies off the floor, it had to have a screen and be removeable.

It's held in place by a wingnut.

Power supply and motor drive mounted, new long lever microswitches installed. The power supply is supposed to be 12v, but is putting out 14.4.
It's almost a waste to not be using it for an audio amplifier. I may switch it out if I find a true 12v one that can handle the current for free.
The wire I used for the motor driver to the printer port was way thicker than it needed to be, but I already had spools of it and just happened to have all the same colors as the pigtail that came with the motor driver, plus two extra colors for the limit switches. :)
I stuffed them inside 3/4" heat shrink to make them into a solid cable.

Final, final rotation mech assembly:

Pretty much self contained and has 4 cables coming off of it.

BadMouth:
Started painting the inside and back a little while back.
I had originally planned to use grill mesh for the back door, but I messed it up trying to cut it with a jigsaw.
Really need to buy an angle grinder.
So I just went with an open area for the sub and port, since the front speakers have no grills.

Speaker shroud finished and mounted.

I managed to poke a hole in one of the speaker surrounds when installing the speakers. :angry:
It won't have much of an effect because it was one of the sealed back mids and they are pretty limited to upper midrange, but it still bothers me.

It's a bit premature, but I was in the painting mood and wanted to make progress.
Decided to do paint instead of full side art because it's cheap and easy to repair.
The artwork will probably be limited to a couple logos on each side and the Neo Geo coin arrows on the front.

This is just a WIP CP that isn't quite right in a few ways, but this is pretty much how it will look.
(ignore the thin board sticking out the front, it's just holding the panel behind the main cp up)
The white panel is a move list/instruction card holder. The button layout for player 1 sucks in practice and will be changed to match Player 2.
The player 2 side is the same, but rotated left. It feels great, but I still might adjust the bottom row a bit.

I'm sick of getting dust on everything again and again, so after the paint has a few days to cure, the cab will be moved upstairs and monitor installed.
The CP isn't done because I'm experiencing some feature creep and having to rethink the design to possibly include more controls. ::)

The CP will also slide to the right so player one is centered when playing vertical shmups and classics.
When the CP is moved, usb inputs and some extra features will be revealed. I have the sliding mech worked out,
but the mounting of the extra features is going to take a while to work out because it all has to be removeable and serviceable.
I'm also experimenting with the idea of having the CP slide a little in the other direction so moving it could be used to nudge in pinball games.
(even though I hadn't planned on installing pinball games...... damn feature creep!)

Le Chuck:
That is one damn sexy rotation mech you've got setup there :applaud:

Hat's off to you.

Nephasth:
Looks great inside and out! Love your attention to detail! :cheers:

Thanks guys.

Part of the feature creep has cleared customs (luckily >:D ) and should arrive in the next few days.
