OpenGL accelerated SDL2 with no X running is very nice, boots fast too, probably in about 10 seconds-ish? It feeds out to an LCD of 1366x768 size, which is a nice physical size for the backbox. The raspberry pi takes commands from the master board that basically just tell it play sound effect X, play images Z etc.

It spends its entire time basically doing millisecond timing of all 32 solenoids which is nice to detach it from the master board. The nice thing is I have this all running inside the chips cache so its running at its full 80mhz speed. 1 core will be driving the HC595's that turn the solenoids on/off, the other 7 will each run the timing of 5 solenoids (last one only running 2, tallying up to 32). The solenoid driver is run by a propeller chip, which can run 8 threads simultaneously, which is fantastic for timing all the solenoids on/off with PWM at once. Once I have that back from being fabbed I can start work on the playfield whitewood. I've bread boarded the solenoids for testing, so now I've got a schematic design going in Eagle. One of the first things I decided was that it would have some form of colourdmd and the only way to do it was an LCD. All the A/V work will be done on a raspberry pi.

A Solenoid control board for driving up to 32 solenoids. Master controller (UBW32 pic32 board) with custom shield doing the game rules, switch input and lighting. I'm doing my own electronics because I think PROC is massively expensive for what it is and what you get. Sooo with theme in hand we proceed to the nitty gritty.

sounds pretty good to me actually, and I have 200+ hours playing skyrim, so I kinda like that theme idea. Originally my theme was Big Trouble in Little China but the wife pointed out, the first time I do something I tend to mess it up a bit, so shelve the idea I really want, and go with the backup which is Skyrim! A TESV:Skyrim pinball machine. I've been working on a DIY pin for a few years on and off (mostly off, you know, wife kids chickens dog life etc). So, I've seen a few DIY threads popping up, so I figured I'd add mine to the list.
