Hi, some really great first timer questions. I will try and explain what I have read from past forums and experiences.
1. Pots lines on the R/B/G wires to allow for picture adjustment?
This I believe is important when using XRGB mini framemiester. The raw signal coming from the arcade boards come be much greater then it is really need. Causing the source to not have very much variance. Put pots on your lines good idea.
2. 5 pin to a male 8pin din?
I believe most around here recommend this for pure convenience and easy plug and play. Pretty easy task if you have the tools and pieces/ parts needed to take care of the job.
3. RGB mini would negate the need for encoders or sync strippers?
This I really do not know much about, however, I would love to hear someone else's that is experienced with the device.
4. 220-280 ohm resistors on each line?
I have read this too. Once again, I believe this is to tone down the signal and regulate it more. Also, I would assume having the resistors on the lines would allow for better controls once it is inputted in any device. Similar to add pots to your lines before inputting your signal wires to the XRGB mini framemiester.
5. Advice and/or suggestions?
First off, good for you to take on the job of building and designing your own. I have build three total in the last few years. It is a very patient and relaxing experience. Try not to feel overwhelmed. Just remember this one simply concept. The whole thing is just positive signals looking for grounds. That is it. Seriously. Unfortunately, one of my own mistakes was size of supergun. MIne is HUGE!. Granted I also have my CPS3 inside the enclosure with the supergun parts. Kind of a ALL-in-ONE box of Street Fighter III: Third Strike! YEAH!
.
I wanted to protect the CPS3 because it only comes with the metal cases that I do not trust others being around.
Back to what you want to know, WHAT I USE?:
1. Video - JROK 4.1 component Video Encoder for most of my video processing. I also take my raw RGB+S and have those available as outputs for monitors or sources that accept it (output is BNC).
2.Controls- I have both DB15 and UNDAMNED usb encoders. Both are wonderful. UNDAMNED is a beautiful device. Highly recommended, however, the solderless terminal version of the device is no where to be found.
Paradise Arcade Shop sells the device but has not had them in stock since late December. If you can limit your time using a solder iron, I feel, you are going in the right direction. Especially, if this is something you are not experienced or have not performed at all. JST connections are the new standard when building. A little tricky at first but pretty dope when you got the skills to handle it. Takes away the need for a soldering iron. I suggest watching the
HOW TO video of Building a Supergun. I have watched this countless times. Keep in mind he is go to setup that supergun for DB15 connections. That step can be optional now with the help of
UNDAMNs USB.
3. POWER -Finally, POWER IT UP!!!!! Power Supplies: I use
POWER PRO 130W UL, CL, CE POWER SUPPLY. I find this to be the choice for those trying to build a supergun small and compact from video of builds. Keep in mind you can find this cheaper elsewhere. It is a far better PSU than the cheaper ones from China that are compact. Granted I don't wanna knock too hard on the cheaper Chinese made ones because I was a new guy and used to own one It sadly died on me in 9months. I have since switched to the Power Pro and have had no said issues (knock on wood for good luck).
Last few comments: Remember the right tools for the job. Shop around for parts. If you need to solder try not to burn yourself (it hurts not a good feeling). Take your time and double check all of your steps and connections for voltage lines. These are VERY IMPORTANT, stuff can blow up or even straight burn or start a fire (believe me I almost burnt my whole super gun. I have ran two pretty decent size tournaments with my supergun, cps3 multi, cps2 mulit, and naomi net dimm multi boot. And will be running one this April 1-2. I LOVE THIS THING. ITS GREAT!
These people that are here at this forum are here to help you and others understand the importance of the craft of arcade goodnesses. Most of the knowledge I have consumed is because of these individuals or because I have followed individuals from other sites to this site.
You have great questions that I am sure other want to know. And remember..."If you build it, they will play it." - Jon Harris (Good buddy of mine told me that when he gave me a crazy amount of money to go build the supergun for our crew twitch.tv/povertygamenight.
NOW GO BUILD A BADASS SUPERGUN FOR ARCADE BOARDS AND TAKE OVER YOUR TOWN, CITY, STATE, or REGION. LET THEM KNOW, "I GOT THE POWER NOW!"......I'm out.
