Not to often that a product really impresses me. In Pinball, Color DMD did when I first tried it on my Addams Family. That is what the DMD was meant to look like if the technology had been available in the 90's.
I always thought I would stay "pure" and not try LEDs on my B/W DMD games. STTNG, TAFG and TZ. Well having WOZ next to TZ made me wonder if LED's could brighten up the older game. That and we all like change once in a while, just ask my wife how she feels about our contemporary house now Black Friday sales with 20% off at Pinball Bulbs .com so I bought two kits one for TZ and one for TAFG. Learned a lot about LED's since then. Learned about ghosting issues, flicker, inability to dim GI, and the ghosting patch for B/W ROMs.
TZ with 9.4H ROMs already has the anti ghosting patch so no issues there. I do seem sensitive to flicker, sometimes even noticing it on my high end computer monitors, so I did see flicker on TZ most of the time. Only noticed it sometimes on the GI but of course had to turn off GI dimming. Didn't realize I would have to do that till after I bought the LEDs.
Even with the issues though I really liked the brightness, and insert colors with the Pinballbulbs kit. Game still looked good.
Read the accolades and watched the videos on games with LED OCD and tried making my own with an IPhone 6 in slo motion mode. Holy S#!^ If you have an IPhone give this a try the flicker is crazy. So I decided to purchase a couple of the LED OCD boards. (GI OCD boards were out of stock)
Really top quality looking product, No issues with quality at all. Installed pretty easily with the main board upper right of the back box and breakout board on the bottom just below the matrix connectors.
Turned it on and no flicker in fact attract modes looked perfect. Software installed pretty easily on my laptop and connected to the board on the second try. I had to make a few adjustments. The bulbs in the start button and extra bulb are incandescent and I changed the delay to 1 on the 2 profiles I used 7 everywhere except for the Piano and Slot Machine colored LED's where I used 5. With the stock delay at 3 attract mode was fine but during the game the door panels did not flash as expected. Improved at 1 and 0 delay, left it at 1 for now.
Slow motion Video is not great, sorry, but you can see where I switched from bypass to LED OCD board controlled at about 44 seconds. Now the flicker you see is just in the GI. The software has this bypass setting so you can see how it is changing things.
Now I just have to wait for the GI OCD boards to become available again.
