I just finished up doing a VGA mod using the mmmonkey tutorial. I've never seen someone mount the vga connector using the method I chose so I figured i would post some pictures. It does require you cut some of the metal plate shielding, but it allows you to connect everything to the dreamcast motherboard as one unit. Anyways, what do you guys think?
lol, yeah, I wanted to mount it there and couldn't think of another option. I know I went overboard on the glue, but I don't think It will cause any problems. I kind of had to pile the glue on just so I could attach it solidly.
Oh yeah. The only porblem with that location are the capacitors, they stick up just a little too much. I had to take the metal plate off of the GD rom drive and there's plenty of room. I'm not sure if it's necessary or not to keep that metal shield on it, but I'm going to remove those capacitors and mount them on a wire so I can lay them down flat.
I like the vga port placement... you could screw it on the case instead of using glue ... but in the end it works too
I agree, I like the placement too. But being upside down would annoy me (not got OCD, but it feels like it sometimes!)
Nice mod! Anyone knows the minimal wattage for resistors and minimal uF rate for the caps? Would be nice to make a surface mount version.
Haha, I know what you mean. The only reason the port is upside down is because the pins come off at a right angle at the other end and I had to bend them down so they wouldn't stick up so high. The one side of the port has a lot more plastic along it covering most of the lower pins which gave me a better surface to glue down. .
Wires are quite long, would make sense to use shielded wires instead so as not to degrade the image quality or introduce interference.
I have one of those Chinese clone ones that is really small that I plan to use internally at some point. Quality is good. Video goes to 15" Toshiba laptop screen with a 4:3 1024X768 resolution through ANOTHER Chinese VGA adapter for screen... It works flawlessly in the Dreamcast VGA 640X480 mode.
That's a lot of vertical pixels you got there. Seriously though I was planning building one myself, for the sake of it, and for that it'd been nice to know the minimal wattages and capacities, as those are kinda low with smd parts.
