Artwork looks great. I hope the cab will have the notch in the back you show on the artwork. That's a great touch. :cheers:

Im with ^^^^^ The notch makes a big difference in style. I love when my pit makes those faces.

BadMouth:
Thanks for the comments!

I'm going to incorporate a way to attach it to the wall.
It would probably be fine with some weights mounted in the back corner, but not going to risk it.

The notch in the back is indeed the shape of the cab. ;D
It was originally just for asthetics, but it will also allow the cab to sit closer to the wall while still getting ventilation.

The pitbull is a throwback to neo geo advertisements in the 90's.

I didn't want it portrayed as rabid though.
The one on my workup is just copied and pasted from the internet, but I'll probably stick with it.
There will be other, more subtle NEO-GEO references throughout. ;)

I put the PC together a few days ago. It's basically my old desktop with a new mobo and the processor leftover from upgrading my driving cab(3.2Ghz Athlon X2).
Much to my surprise, the system builder version of Windows Vista originally on the computer installed and registered without any issues.
(it was my understanding that it was locked to the motherboard and not transferrable...was expecting to have to call microsoft and whine).
It's not bleeding edge, but should get the job done. The only thing I had to buy was a budget mobo and CPU fan.

The reason I decided to use Vista is because I already had it and the newest version of Demul requires directx11 to see any improvements.
Since this cab will lean toward Atomiswave and Naomi games, Demul is a requirement.
I also haven't been able to get the Taito Type X2 game King of Fighters:Maximum Impact Regulation to work correctly on Win7.
I know they all work on this hardware and OS.

EDIT: can't get the directx 11 plugin to work now. :banghead: I swear it worked before reinstalling vista.
I'm using the same video card which is only directx 10, but it was working.
Pretty sure I've done all the updates (been updating for 3 days now). Must be missing something.

My schedule opens up in a couple weeks and I'll be able to start on the woodworking then. :cheers:

LOL yeah the original dog looks like it may have some medical conditions!!

I cant wait to see the 27" LCD installed!!

BadMouth:
After some more windows updates, the pc now has directx 11 and demul .5.7 is working just fine. :applaud:

After tinkering with the Naomi & Taito type X shmups, putting the monitor on it's side and realizing how awesome they are with a vertical screen, I've decided to add monitor rotation. ;D
That little design change has slowed me down a bit while I thought about how to go about it and ordered the parts.

I picked up the lumber today, but haven't made any cuts yet.
Here is the progress I've made on the rotating mech.

Started with a wall mount TV bracket and hacked some out of the center:

Added 200mm lazy susan bearing from fleabay. The bracket is deeper than the lazy susan bearing is thick, so I'll have to add some spacers for everything to clear. I could have flipped the bracket over, but wanted to do it this way.

Traced the monitor onto foamboard, drew on the screen position, punched a hole where the center of the screen would be, and then where the VESA mounts are. This wasn't easy because sides of the monitor are slanted and the back of it is curved. I had an "L" shaped piece of foamboard leftover after cutting out the monitor. I used this as a square, holding it flat against the back of the monitor and marking the VESA hole locations while the other part of the "L" was against the top, then side of the monitor. Note that the VESA mounts are not centered with the screen or the monitor frame. By the VESA standard, they are supposed to be located at the center of gravity, but I don't know if that's always adhered to.

Then added some horizontal and vertical lines accross the center, lined the lazy susan bearing up with them (just eyeballing and lining up the lines in the center of the mounting holes), and marked the lazy susan mounting points. So there's pretty much the pattern for the monitor mount.
EDIT: this pic is upside down

Foamboard monitor bolted on for testing:

The main purpose of doing all this was to see how much clearance it would have when rotating since the bottom frame of the monitor is wider.
Answer: hardly any. I was planning to make the inside of the cab the same width of the bracket, but I'll have to add some wiggle room.
I'm surprised how accurate the center hole looks. It appears stationary when the monitor is spinning. I hope the real one turns out that good.

Here is the gameplan for the actuator:

I still need to make the mounting plate & actuator mounts. Don't know how I'm mounting limit switches yet. The cables have to pass through the center of the bearing somehow. etc etc etc.

I reaaaaaallly want to be centered when playing shmups. I figure it's either squeeze in another joystick & 3 buttons in the middle, or make the CP slide to the right. At least I have a width to the cab now (32"), so I can start doing some CP layouts and see what works. The games will be unplayable from the player 2 position when the monitor is verticle because the viewing angle from the bottom of the monitor is so bad. It looks awesome from the left or center.
