Jamma Video Signal Splitter, Interest? - Now Available!

Hello,

I just finished a design for MAGFest to buffer and split the video signal for jamma based arcades. We are using it so player can play on original monitor and we can then send the buffered signal to a VGA scaler for displaying on projectors alongside. Scalers are not designed to work in parallel with the monitor but this device will allow you to do so.

Anyone have a use for this?

- Alright enough people were interested

First Rev is up and for sale

Newest Design will be ready soon, early March, It includes a line out for audio and I also put a +12v pad in addition to the ground and +5v pads.

Seems like something that would be good for doing old-school tournaments, or even small scale in home ones, so everyone is not crowded around the players
 
That is the idea! We are using them for tournaments at MAGfest and I am about to put in a large order of the design. Was looking if anyone else is interested
 
Very interested. I run an arcade similar to the Magfest one and have been wanting to do exactly this. I'd be in for 5 or so at least.
 
I don't know if I would have a use for one but subscribing as I am not as creative as many on here.

Cool project.
 
Also good for sending to a capture device via one of the RGB-to-whatever encoders, I would imagine. I usually just splice an extra lead on RGBS of a JAMMA extender, and take that to an encoder, but this would be much cleaner.

Would be good to have an optional cable to interface with the encoders on the market (standard 5-pin female plug, like the one that plugs into the CRT chassis...here it is, for reference: http://www.jst-mfg.com/product/detail_e.php?series=258)

Would also be cool to have pins for audio out, along with a cable that would connect to the splitter, and 12" of lead wire for each pin, so a RCA connector could be easily wired up to said cable.

Maybe going off into the weeds with your idea, but just spit-balling, and I think it could open it up to a wider market.

(^including the hardcore DK players that are constantly streaming their gameplay. :D)

Not a fan of impedance matching are you....
 
Oh Wow there is a lot more interest in this than I thought.

The design worked great. It fixed the issues I was having and allowed you to be able to adjust the monitor signal and then adjust the signal on the scalar separately.

As far as taking the audio out, I have considered it but the audio is at speaker level so to save cost and time I have just left that out for now. I was in a crunch to finish this for event.

I may make a future version with a voltage divider and one more opam to bring it down to RCA levels with an adjustment pot. If you plan to use it for streaming, I suggest just using a mic. Depends on demand.


I'll post a price soon. I have not figured out cost per unit yet. More info soon
 
Can't wait! My event is coming up in a few months and I want to have this in place for a special tournament we're doing!
 
Have you thought about changing this from Jamma to just interfacing at the monitor RGB connector? That would open it up to a wider audience and allow for streaming the classic games as well.

We went JAMMA on this because it's a standard on the newer games that delivered power and video signal. Making a splitter board that plugs into monitor connectors would involve a lot of different styles of monitor connectors, and there is no DC power there.
 
I am looking at $28 shipped in US.

The board uses high quality op amps to replicate the RGB and Sync signal and breaks them out along with the video ground to be hooked up to a GBS8200 video scaler. It also includes a 5v breakout header to power the GBS8200.

PM me if you are interested in ordering some and what quantity. I will considered doing quantity discounts.

That makes sense. Will be easy enough to make a board that has the inputs I need adapted to JAMMA to feed into this. Won't need to worry about the output side as it will just go to the scaler.

I think no matter how you did it, there will need to be customization for anything that isn't JAMMA. But there may be a market for adapter boards for you to explore!

Do you have a picture of the final product?
