When you start hauling your SG around to other people's houses and they don't have a television with component inputs, you are going to wish you went all-out for the composite/S-video/component JROK.

Anyway, sounds like you have everything planned out, so I look forward to see how it ends up.

You bought a couple of things from Radio Shack and online... in the future, you can probably save a lot of money by finding a local electronics shop - the kind which has things in little plastic baggies from floor to ceiling. Have a look in your telephone book.

Well all my friends have component HD LCD flat screens, im using my 36 inch Sony HD CRT.

Just started modding the case........

First attempt at inside mounting DB15 connectors, pain in the ass!

Edit- Fucked up the other side, mounted them both on outside, look good now

So many terminals... what do you plan to use them all for?

Well i want to keep everything organized as best i can, the front row will be for the controller ports (12 ea.) The two rear terminals will be for +5V and +12V for power using a bridge, the the middle strip will be for grounding and the small strip for the JROK RGB, sync, and ground connections

Gwyrgyn Blood · Post by **Gwyrgyn Blood** » Mon Oct 27, 2008 3:47 am

Personally I think it would be neatest if you just bundled the wires and ran them along to their ports when possible. Terminals take up a lot of space and with so many of them they may end up just being messier using them. At least, for the controllers anyway. Sound and Video depends entirely on how elaborate your output options are.

Wish I could show you a picture of what I mean but the Supergun I have here is a trainwreck I didn't build myself and learned a lot from. :X

lawnspic · Post by **lawnspic** » Tue Oct 28, 2008 1:37 am

Well, i got to say the toughest part is out the way except the grommet for the Jamma. No i just got to hook it all up.

BTW i suck at cutting cases, its not the worst but a few things are slightly off

iatneH · Post by **iatneH** » Tue Oct 28, 2008 2:20 am

Nice back panel, I probably should have used fuse holders like that too for my gun.

Agreed about the terminals. With all the space they are taking up, you probably could have had enough space to mount the PSU board internally if you skipped the terminals.

The case is deceiving, its just 2in high (the arcade PSU would not fir inside even with it removed from the steel case) Also i like the idea of it being separate, it might limit video interference. I think im gonna get rid of the teriminals for the controller. I liked it at first because i could add and move wires around when needed with ease. I will post a pic of the PSU tomorrow.

iatneH- Should i fuse the 12 and 5 volt before the power switch or after heading to the jamma?. Im using 2.5A for the 12V and 10A for the 5V

May I know how much have you spent on parts alone? I'm always interested in building one but I'd have to import every single part from overseas

Nice gun you have there thus far, good luck with your finishing

You can build it completely using very standard parts bought locally, you just have to know where to look for them. You ought to be able to find everything from an electronics store (electronic components, not consumer electronics). I'm sure there are electronic hobbyists down under.

Even the JAMMA connector is a standard 56-pin edge connector, it's just way less work (and not much more in cost) to buy one already wired up. But for everything else, it's much cheaper to buy locally. Also, despite mixed recommendations for and against, in my experience a standard PC power supply gives very stable power, and I've been able to use a compact PSU from a dead DVD player for my weaker boards. You can probably get several of these for free without too much trouble.

Give it a try, it's fun (except for cutting mounting holes in the case, as I'm sure lawnspic can tell you all about it now).

very nice and clean... 2 thumbs up

lawnspic · Post by **lawnspic** » Wed Oct 29, 2008 2:35 am

First stage of wiring complete, all power and grounds done, some JROK, soldering tomorrow. Kudos to Matt Ross and Dean for there incredible patience when making these for the masses.

What it should look like when complete

lawnspic · Post by **lawnspic** » Thu Oct 30, 2008 3:11 am

Just got done wiring all except half the controllers. Man this just kicks your ass. I checked all the voltage and grounds at the end of the harness with a tester and all is well. I will do a test run tomorrow with a 4 slot MVS. See ya

BTW that JROK has a nice bright blue led when powered, how cool would it look with a clear plexi front panel? Hmmmm.....

lawnspic · Post by **lawnspic** » Fri Oct 31, 2008 1:42 am

All wired up !!!, running good AFAIK, tested with JAMMA Raystorm PCB

I almost freaked on the audio at first, it was not working, then i realized i was using a patch cord that was not hooked up to my AV selector, Phew!!!. I fired up Raystorm and it powered right up. The audio had a slight hum, and the video had some line scroll, GROUND LOOP!!!. My PS3 had the same problem, easy fix I had to undo the frame ground on the arcade PSU and the audio and video were fine after. I then tried to tweak the RGB adjustments and realized they are best left at default. The colors are very vibrant and crystal clear. JROK does live up to the hype over S-video. Well, im shot and tired and had no time to really tweak it yet. I will post pics of it in action soon.

BTW, anyone want me to make em one?. Maybe the next custom builder, he he! Who knows, but one things for sure its hard work. Later

LOL! I never noticed. It's like how I was with mountain bikes, when a sexy young thing rode by and all I could do was look at what she had installed in her transmission.

lawnspic · Post by **lawnspic** » Fri Oct 31, 2008 3:21 pm

Yeah i thought that was funny as well. I did not even noticed until after i posted th pics.

lawnspic · Post by **lawnspic** » Sat Nov 01, 2008 3:24 pm

This is the finished product in action. I wish i had RGB adjusters on the case, since boards vary with this encoder. The colrs tend to be very saturated unless you spend some time tweaking. Anyone have some tuning ideas? I wish i could find a happy medium. Anyway it runs good, no problems.

jonny5 · Post by **jonny5** » Sat Nov 01, 2008 3:36 pm

dunno if its the pics or not but your colors seem a bit off.....maybe try and set them with a color bar on screen

Yeah jonny it was a combination of the pics and my TV settings. It turns out that someone was playing with my TV (kids). It was on vivid and the temp was set to warm. I set everything back to factory defaults and wow. So the default JROK settings were just fine, it was the TV set. Man the picture is so crisp and clear with vibrant colors and rich detail. I really started this project for the JROK alone as i wanted the ultimate in picture next to true RGB. Well worth the effort. My last SG was great and this takes it to the next level. Im glad i did not buy a Sigma, because i knew it would be lacking certain things such as component and DB15 (those proprietery dins are bullshit BTW). If the person who builds the SG knows what they are doing the are as good as any commercial SG, and there were only a few. Even MAS supernova's i consider home made. I really might consider making these things to sell and see how it goes. If there is a need i might do it, no one else is really doing it at least not in the US. With Matt and Dean gone why not.

For lawnspic,

Very nice compact Supergun you've got there. ^_~

What type of PSU are you using to power up the Supergun? A PC based one or a true arcade based one instead?

If you do plan to make more in the nearby future, it will become more easier for you. That is a given. ^_~

@ PC

I purchased a arcade PSU from Jammaboards.com. I bought a medium duty power cord (16 GA.) and used that to wire it to the wall outlet.. I then bought three conductor wire (16 GA.) for PWR (12V, 5V and Gnd) and ran that to a four pin din to the SG. I really wanted a desktop power supply, but i could not find one that could deliver the correct current (AMPS) or one for a decent price. The arcade PSU is a good choice for me, but for a consumer SG not so good. I would have to put it in the case and would have to sacrifice the size of the enclosure for a larger one.

I dont know if anyone noticed, but quess what? I dont have a controller. I sold my adapter and controller not long ago like an idiot. I think i will get a old style Neo stick or Tototek PSX adapter.

Yes, those cool Neo-Geo AES arcade sticks use a short-throw Seimitsu joystick for instant responsiveness. I've got one and it works like a charm. ^_~
