I've made it and it works well, seems like my SMS1 has a bit of interference on the audio line. Not sure why but it's not on my Genesis 1 so I think it may just be an issue with grabbing audio from the DIN connector. The housing I made is still a bit fiddly so I am working on improving the...
I am using this board to output attenuated RGBS to a custom 8DIN to VGA+3.5mm adapter into my RT5X. Everything is working good except for the overall brightness. Looking at the Unibios color bars, the white ramp ends at a light gray. I'm wondering if I can just remove the 75ohm resistors on the...
I got around to building the console VGA dongles created by Jeff Chen and loved them so much I wanted to design one for my SMS and MD1. The original creator of these dongles doesn't have any plans for making an 8 DIN 262 or 270 variant so I went ahead and made both, however I will only be...
Yeah and then I had the idea to create a circuit using a potentiometer and some logic but life got busy and I moved on to other projects like my FDS stick mod
I've been trying to improve my skills with CAD software like fusion 360 but I can't stand watching a yt lesson or series because I know a lot of the base material. My solution? Jump into a project that seems way over my head and learn as many new techniques as possible along the way. I decided...
Looking for a PC Engine multitap, can't be the Duo Tap or Turbo Tap as the connectors don't fit and I don't want to get adapters for all my controllers. Thanks!
You just need to solder a potentiometer to each of the positions on the edge. Usually they have 3 legs, you'll only need to solder 1 to the edge and the other leg to the wire going out to the monitor.
You could try adding like 2k pots to the RGB lines and turning the resistance up should lower the brightness. Could you get a voltage reading of RGB and sync off the JAMMA edge for us?
