But, please more pics! I am especially interested in your rotate mechanism, since Im working on one..

I took a look at your thread.. so first - I cheated. I used a 20 inch (4:3) LCD monitor. I did this for 2 reasons:
1) I wanted to be able to take the top off to use it as a pedistal in the Home theater. That meant a serious reduction in weight. As it is, its still really heavy, and I should have used more 1/4 inch MDF on the back.. Oh well. I can get it down if I really strain, and 2 people , one on each side can take it down easily.
2) NO Degaussing Required.
An LCD has the disadvantages of being really expensive if you go larger than 20 inches (I think this one is an Acer I bought at New Egg for around $220) and if you get too far off axis, you have a hard time seeing the screen. Luckily thats only an issue in the 3x4 position, and I have no 3x4 4 player games loaded (are there any?)
You could of course, attach a large pully (wood cutout etc) to the monitor and do the same thing, but I think for a CRT, you will need something larger than my little hobby motor..like it looks you are using. The Premade circuit from Solarbotics I used can drive anything upto 600 MA load, but I am not sure thats enough. Anyway, from your thread it looks like you are on the right track..
My goal was more or less to provide an easy, cheap (around $50) way to rotate an LCD, that required a minimum of soldering and electronics work and worked mostly under program control. (if anybody wants the binary exe file I used for the control, just email me and i will ship it over..)

Love the etched plexi. :o Legendary!!!! Are those electric ice buttons? if so where did you get the maching balltops? The only thing that has prevented me buying a set is getting a replacement for my light up bubble ball.

Yep, electric ICE using the older, less bright LEDs. I got the sticks at http://www.slikstik.com/index.asp, they are just shafts to use with a regular HAPPS SUPER joystick. Looks like they are carrying Trackball upgrades now as well, but I got mine from Groovy-Game-gear. Had a good experience with that- just screw the LED PCB to the bottom of my old WICO trackball and drop in their ball instead.. Had a great experience with both companies.

That is an awsome cab. Im in love with the new slim style that is catching on using lcd screens instead of crt. The CP is amaizing!!

Again, great job!
I thought about going with a 19" LCD (which the viewable area is about an inch larger than the 19" CRT), and I was going to do that if I couldnt get the problem I had with the CRT monitor worked out.
But I think I do have that problem fixed now, so Im going on with the original plan. Unless my mounting mechanism is too big for my cabinet.
I plan to cut circles out of MDF or ply to fasten the CRT to.
My motor draws about 1 to 2 amps with no load, so your drive would not work for me.
The drive I am using is only good for 4 amps, so that may not be enough when the motor starts to push the monitor around, if not I have a back up plan, using 10 amp relays.
I would be very interested in trying your program, can you post it here?
If it is too large to post here, let me know I will PM you my email..
