Virtual Pinball Backbox Display Mounting Made Easy

Starting with a backbox that has a hinged door, we cut out extra holes where the AC plug and the VGA connectors will go.

We remove the hinge and relocate it back about 3 inches or so.

Put a stop block on the other side to keep the swinging door from going in all the way

Steve brought me a 24" LCD and a 14" LCD. We mount each of them on a plank that will get screwed onto the swinging door that we just recessed.

The threads on these monitor mounting holes were metric M4 -.7

Position the monitors, then screw mounting brackets onto the swinging door.

No need for de-casing the displays. They both fit neatly in the backbox.
Now all we need is to cut a bezel from 1/2" MDF and route some proper-sized
rectangular holes for the displays.

More Virtual Pinball pictures

OK, here is the Rawhide Virtual Pinball cabinet, finally ready to play.

Legs are not attached, it is still on the dolly so I can move it around in my limited shop space.

RAWHIDE Virtual Pinball General Debugging

Each Virtual Pinball cabinet presents its own set of challenges. This Rawhide is no exception. Here are some of the issues I have had to deal with in the building process:

EVGA GeForce 210
This video card would not hold its settings for dual display. Every time I rebooted, I had to physically swap the display connectors at the card to get the playfield and backbox to display. I returned that card and got a different one...

ASUS 210 Silent
This video card worked fine for configuring dual display, but when I assembled the cabinet and started configuring tables, the DMD would freeze or go blank when I dragged it from the playfield to the backglass display. Tried all kinds of tweaks and settings, but nothing worked. I returned that card and eventually got an EVGA GTS450, which is what I have in my first Hyperpin, and it worked fine for dual display.

Proview 32" monitor
This monitor does not power up when AC is restored to it, and the ON/OFF is out of reach when the display is mounted in the cabinet. I had to rig a lever to physically hit the power button. Primitive solution, but it works, and saved me from having to disassemble the button panel.

Ball movement shuddery... this I discovered was because the displays were connected to the wrong ports. I swapped the displays and now the ball movement is smooth like it should be.

Flippers and Plunger not behaving properly.
I am using a Keywiz (which has a PS/2 interface), and the PC is a Dell GX280 that doesn't have PS/2 ports, so I am having to use a PS/2 to USB Y-adapter. This does weird things to the keystrokes. The plunger, when pulled, will misfire (or release prematurely). The flippers will not hold when I keep the button pressed. It will release, then if I keep the button held down, it will stay up, but this is not really acceptable. I ordered a PCI card with PS/2 interfaces today, and hopefully that will solve the problem.

RAWHIDE Virtual Pinball Display switch

The Proview 32" display will not turn on automatically when AC power is restored to it, so I had to rig up a lever to hit the ON/OFF button on the bottom of the display.

Just used a latch with a metal strip epoxied to it. I also epoxied a bolt head to the end of the strip where it hits the button.

Just a little push of the lever, and the display turns ON.

RAWHIDE Virtual Pinball... making progress...

Almost done with this one.

The bezel was put together from 4 pieces of MDF. This technique is easier than trying to route the opening from one big piece of MDF. I know, I tried it that way...

Just needs the glass and legs now. Also need to tweak all the tables.
