Quoted from ypurchn:so I looked into pin2dmd and was overwhelmed by the piecing together of parts required. does someone have a cheat sheet or a dumbed down version?
I wanted to do it as cheap as possible and in the end I built 3 of them for $130 each including a tinted front sheet.
I bought:
Panels off aliexpress. They come with wiring too which is cool. Make sure they are 1:16 scan RGB(some are like GRB or something). You need 2 of them that are 80x160mm p2.5.
Stm32 discovery board with Pin2dmd shield from uncle sash. I contacted him through vpuniverse forums and Facebook but I think he's on pinside too.
12-5v 5a voltage regular off eBay for like $3. Hook to pinball 12v power, I used the same pinball connection point as colordmd uses.
I designed and 3d printed my own frame but I think you can get that from uncle sash too.
That's really all you need. feel free to contact me if you have questions. Best thing is to join the vpuniverse forums where there is a specific pin2dmd forum.
