EDIT... Finished:
I've got the control panel (thanks Virtvic) cut, and overlay (thanks Muddymusic) applied.
I've connected it up to a MAME (emulating a 4-slot), with MAME Hooker and Arduino powering the credits (a 2-digit, 7-segment led on some veroboard) :
I'm going to light up mini marquees too.. and have this working really well on a breadboard at the moment:
Still to do:
1/ Get the cab and strip out the DK bits + art.
2/ Add a small de-cased windows PC, probably core2duo, running groovymame.
3/ Add a memory card slot and headphone jack under the control panel.
4/ Finish drawing the rest of the art and get it printed and applied
5/ Cut a clear acrylic bezel.
6/ Look at changing the coin mach to 100 yen.
Here's the arduino code if anyone wants to have a go:
Code: Select all
// Dual seven-segment LED Display
// Common Anode digit 1 pin 14
// Common Anode digit 2 pin 13
// F G A B C1 C2 M H I
// | | | | | | | | | -> pins and segments they control
// --------- ---------
// | A | | H |
// F| |B M| |I
// |---G---| |---N---|
// E| |C L| |J
// | D | | K |
// --------- ---------
// | | | | | | | | | -> pins and segments they control
// E D C D1 L K N J D2
// Segments that make each number when lit:
// 0 => -FEDCBA
// 1 => ----BC-
// 2 => G-ED-BA
// 3 => G--DCBA
// 4 => GF--CB-
// 5 => GF-DC-A
// 6 => GFEDC-A
// 7 => ----CBA
// 8 => GFEDCBA
// 9 => GF-DCBA

// corresponding segments on the LED display

- but I really fancied messing around with an arduino, electronics and mame hooker to be honest.I don't think anyone has fed a credit LED / marquee lights from MAME before.
