You never know what a 6 year old will do to the hardware… And if it breaks, swapping in a new game board will be easy. I chose this solution to keep everything as simple as possible. The manual of the device includes a wiring diagram to make the cabling easier. The games in the machine come from an ‘Pandora’s Box 3’, which holds 520 arcade games on a on a single JAMMA board. It has a VGA output so it’s really easy to run it on a modern LCD screen. The black box on the upper right is a 520-in-1 ‘ Pandora’s Box 3′ games box that I got from China. The PSU was mounted to the bottom right side of the cabinet using some metal brackets. Easy peasy 🙂Īs I just needed 5V and 12V for powering the electronics of the machine, all unnecessary cables were removed.Īn appropriate sized power chord was addded to the PSU and all cables were guided out the back of the PSU case. If two of the cables are shorted, the PSU will run without being connected to the motherboard of a computer.

…and here is the finished control panel with a Metal Slug inspired vinyl overlay. The control panel graphics was also printed by rockstarprint ( link).Ī cheap way to power an arcade machine is to use a left over ATX power supply unit (PSU). Latches were mounted on each side of the cabinet to strap the control panel down. As none of the games in the final machine support this, the hole was blanked out with a piece of wood.Ī couple of hinges were mounted at the bottom of the control panel to make maintenance easier. However, the control panel was made to also accommodate a trackball. The control panel was handmade by a guy who really knows how to weld! I got it from another guy who got it from the welder-guy as part of a pinball deal… He has only made a few of them, so I guess I got lucky. Two aluminum rails hold the marquee in place with some black screws. The marquee vinyl was printed by rockstarprint ( link). The two cold cathodes for lighting up the marquee.įinally, the marquee graphics was mounted between two sheets af acrylic material.

This makes it possible to adjust the volume during gaming.Īnd a nice looking black aluminum knob to finish the volume mod. The signal cable to the loudspeakers was passed through a 1000Ω linear potentiometer. They are for lighting up the inside of the marquee.

In the background, two white 12V cold cathode lights can be seen. The game sounds are in mono, so I daisy chained the loudspeakers.
