Finally came the time to put it all together and make it purty.
To elaborate on the controller issue I hinted at earlier. I originally wanted, and had LEDs. I had 8 LEDs total in parallel pulling from both the 3.3v and 5v lines on both controllers, so about 2 LEDs for each source. These were LEDs designed for 5v applications with resistors for 12v applications. There were issues regarding the LEDs. After a few controller PCBs kept messing up, I noticed that they only started fruiting out after I connected the LEDs to it, so I had to disable all of them. When connected, eventually they would start causing phantom presses that would never stop, even after disconnecting them. It's like they were modifying the chip coding or something from the voltages now being utilized. It's a shame, too, because everyone knows LEDs make everything look 100x cooler. I'm wondering maybe 8 was too much and maybe I could get away with just a few, but after having to trash 3 controllers (I get a batch off ebay for cheap because they're "broken"), I was tired of the old wiring song and dance, so I just jettisoned that idea.
Some may notice the color difference on the orange buttons. I had two from lizardlick years ago left over, and ordered 6 more from Bob Roberts, and they were slightly different. I'm not anal enough to spend another $10 to get two more shipped just so everything is exactly the same.
Also, if you look closely, you'll see I actually soldered a few pieces of ribbon/cables to the mobo pieces, to create the illusion that things are connected.
Now, what were the holes for? More electronics, of course. See what you can recognize in the last pic and the next post!
