Here, I am underway on the wiring of the misc buttons...





As I mentioned earlier that I was hoping that the power strip had a master outlet that would turn on the TV's when the pc was turned un, but it didn't turn out to work like that. Sooooo I had to take the little circuit boards with the buttons on them from the two hdtv's and solder wires on to the tiny solder points. I was able to figure out which points to solder to by looking at the circuit board traces (at least I was hoping I was right heh) Here are the two boards with wires attached-



I figured I could just wire these two boards together with the pc's power switch and power the whole works up with one button, but it didn't work like that. Weird things were happening- the pc would power up, but the tv would momentarily come on then turn off and when I tried to turn it back on, the pc would shut down.. I tried it a few different times to no avail. I just ended up installing two more buttons on the underside of the machine, next to the pc power/reset buttons. Not ideal, but at least it's within easy reach.

I need an analog switch/s to control bumping and tilt, so I figured I could modify a plumb-bob switch for bump in 3 directions and a tilt switch too. On the left is the metal contact plate that comes with the plumb-bob switch assembly. I need to cut this into four sections and still have it retain its shape so I figure I can glue it down onto some non-conductive acrylic so it will act as four separate switches. You can see the pencil lines I have drawn for cutting.



My dremel made easy work of the thin brass plate



Some cheap super glue does the trick here





Attaching wires-





More wiring- I really do enjoy wiring up switches and soldering and stuff, although sometimes I can be overly anal about it.



Here you can see the two additional buttons I put in for the tv power switches on the left side by the fan. The buttons from the front of the machine are-
power (top monitor)
power (playfield monitor)
power (computer)
reset (computer)



Everything is wired up and ready for testing thumb.gif

Thanks for looking! Please leave any questions or comments below cheers.gif

Well, the next thing to do is drop the screens in. The backglass screen slides down into the machine fairly easily with the (wood) bezel removed out of the way, although I did have a hand doing this just in case. The playfield monitor rests on two side rails screwed into the sides of the cabinet. Clearances are pretty tight-





I put a couple bolts through the side of the machine, going into the metal frame of the playfield monitor so it could have a pivot point, so I could lift it up from the front like a hood on a car, to allow for easy access to the computer and other stuff in the lower compartment.





Once it is up, tilting slightly towards the backglass monitor, the monitors frame hits the side rails and it can support itself in the upright position which is pretty cool and I didn't even plan for that. I thought I would have to use some kind of kick-stand...



When I turned it on, I was getting a 'HUMMMMM' from the TV's speakers that was unacceptable, so I added in a lepai 2.1 channel amp and redid the speaker wires to run to the amp instead of the monitor. I also had to add in a outlet adaptor, as the power strip only has 3 always on outlets and the other outlets only get activated when the strip gets some kind (any) of IR signal. ah well, I would have been better off using a different power strip/surge suppressor, but it's too late now as I modded this one already.

Here are a couple pictures of the lower case with all the components installed-

Next, I prepare some brushed stainless strips that I had cut. At my work, (I'm marble and granite slab mason by trade) we had used some stainless for kitchen backsplash and had some left over that my boss let me use some for the project. As it would happen, right next door to the shop where I work is a metal fabrication and machine shop. So handy! Anyway, I had the metal cut for the side rails, the lock-down bar, and some strips for a playfield screen bezel. These next few pics are just approx. 1" strips used to cover the metal screen frame. I use a file to knock the sharpness off the edges...



Then I use some SpeedTape (very thin, very sticky, double-backed tape) on the 'ugly' side of the strips...



Next, I peel off the tapes backing...



Then it's just a matter of sticking it down along the screen's frame, along the inner sides of the cabinet.

Now, My lock-down bar is not actually a real, working lockdown bar, and it doesn't actually hold the glass in. The tempered glass just sits in the grooves that I had previously routered into the side panels. It also butts the backside of the coin-door panel. I bought a $2 suction cup to help with glass installation/removal. below the glass you can see the stainless screen bezel-





In this picture you can see the wood apron that screws into the corner support blocks, which holds the front of the playfield monitor down snugly.



Moving on, I start laying out the screw holes in the side rails. I am using 5 small stainless steel screws to hold each rail to the cabinet. I also give all the edges a nice once-over with some 220 grit sandpaper after knocking off the sharp edges with a file. These rails were hand bent on a 52" brake, by my boss and myself. we also cut all the steel on the neighboring shops heavy-duty equipment and made 3 bends on the lockdown piece. Later, I had a friend weld the corners of the lock-down piece and had him leave big 'ol welds on the inside corners so there would be some metal there after I ball-rounded the corners.



Peeling off the finish protection to expose the brushed stainless beauty-



I previously drilled out the button holes and rounded the fronts of the rails.



After attaching the legs and the side rails. The button holes match up perfectly smile.gif notice I had to disconnect the buttons to install the rails. This is going to be kind of a pain in the butt when I need to clean the screen/inside of the glass. I will have to remove the buttons and the rails before I can remove the glass. I will think about this when it comes time for revision 2.



Here's a couple finished pictures for your enjoyment smile.gif

bah! I was playing some games on this and heard an electrical zzzzztt! sound and the backglass monitor turned off and would not turn back on. I think its fried. I guess that's what I get for buying a generic, used set off of craigslist. Looks like $200 wasted.

I have taken the monitor in question out of the machine and do not see any psychically damaged parts on either the power supply board or the other board, but I am no expert when it comes to TV repair. I have a friend who fixes TV's so I think I will have him come over for a look.

In the meantime, I have ordered a Westinghouse 46" led lcd from newegg when they had it on sale for $350 after MIR. Hopefully it will show up tomorrow so I can have the weekend to fiddle with it.

I have also ordered some diodes to hopefully prevent multiple signals bouncing of my tilt bob, that I am using for bumping the machine. The multiple bumps are causing the game to tilt. I just ordered them today, so I probably wont get the diodes for a week or so.

Happy 4th of July everyone!

I'm late to this thread.... but once again I am amazed at the quality of bob808's work. Bravo!

No updates since July so I assume this went on back burner. Nice to see you getting some use out of the garage you built... I followed that thread every day!

Thanks Burt! I finished this machine and sold it and built another which is currently residing in my living room but it's for sale too. I already have wood cut for v3 thumb.gif
I'll post some pics of v2 here when I get a bit more time. They are great fun! I'm thinking about doing a 1/2 size with 27" monitors for someone who doesn't have room for a full-size cab.

Yeah a smaller one using 27" or 24" monitors would be a cool idea.
