  1. Im not talking about gel, klirit is kind of plastic. Williams use it in some real pinball in front of display, but of course not dim.
  2. That happen when real pin owner post on vp forum.
  3. Have problem with orange too. Only solution i find is to put dim klirit (dont know how you call that material) in front of panel. But it must be dark brown dim, not black.. Brightnes is almost at max. and RGB is 255/105/0. on one type of panels. Second type i have is 255/75-80/0, First i try 2mm klirit it was ok.. But with 5mm dots look much smother (like on real plasma) there is no edge seen on pixels. By the way, Taking 5V strait from power board is not best solution, specialy on wpc games. 5V regulator is already runing on its maximum. When you ad led panels with white on whole display and brightnes at max it would surtenly reset. Better idea is to take it from 12V unregulated and ad dc-dc convertor. See rapelbox displays he use it too.
  4. First of all i dont like idea powering panels true usb. Thet isnt purpose of usb conector on stm. Also im not sure how much curent stm can hold true 5v lead (before pcb will burn) There is lot of them on alliexpres, look for step down or buck converter. I use this They are good for 2-3 amps.
  5. I use it for real pinball. Did you measure how much amps when whole panel is on? Whole panel white and brightnes at max. I suppose it will be very close to 2amps.
  6. I use this cheap dc-dc convertors, and take supply directly from unregulated 12v on driver board. Not 12v for display (it goes true 7812) take it before 7812, there is 12vA (12v analog) test point on wpc boards.
  7. That is the way. Bravo lucky!!!!
  8. I done frames on 3mm klirit, thet was cat on laser. Here is file if someone need it. front
