My super super gun

Post by invzim »

It's not so much for playing games, but I got sick of manually shorting pins on the jamma edge when troubleshooting boards so figured it was time to get a testbench/supergun thingy.

Stuff used:
  • Sega Saturn stick, hss-0136. Got this off ebay for 30 USD + 50 shipping
    Buttons from an original virtua-tennis control panel
    pico-PSU-120WI-25V, supertiny and accepts 12--24volt input - http://www.mini-box.com/PicoPSU-120-WI- ... wer-supply"
    el-cheapo JAMMA harness from jammaboards.com - I do not recommend this, but I had an unused one
    cable sleeve off ebay
    and old laptop PSU I had laying around
    various connectors and stuffs

The HSS-0136 was chosen because I got it cheap(er than other sticks of that size), not really ideal as the buttons are 29mm instead of normal 30mm - so I had to break out the dremel to widen the holes. The original buttons are soldered to a PCB, so not really practical to use.

The thing I love about this supergun is that it's fully contained, and I can pack it away in minutes and store it on my bookshelf should I need the desk space for soemthing else.

All that is missing is a panel mount RCA for audio which I forgot to order - will snap some pictures of the insides when I get that.

What I don't understand is the use of that Pico PSU as well as that laptop PSU? You just put the Pico one inside the shell from the laptop one? Also, the specs say that it's 12-24V, what about +5?

I've been looking for a small PSU for my Vogatek Supergun, and that Pico model looks neat. :think:

Edit: Forgot to say: IT LOOKS GREAT! :awe:

The pico-psu has INPUT of 12-24V, this is perfect is it allows me to use just about any laptop power "brick". The one I had laying around was 19V. This 19V is then fed into the stick, which contains the pico-psu that gives me 12V and 5V for the game.

So: 220V AC-> Laptop power brick 19V DC -> stick -> pico psu -> 5V DC and 12V DC to game.

Aha! That's great. Does the Pico PSU give you -5V as well? :think:

Finally got the panel mount RCA jack for audio today, so shot a pic of the insides:

pico-psu in botton left corner.

Since last post, I have also changed all of the power/gnd wires on the jamma harness.

I really like this supergun. I'm just building myself a CMVS, then I plan on doing a supergun and this is now my inspiration! Never heard of the PicoPSU before, but it looks fantastic. Thanks for sharing your info :)

I also use a PicoPSU (of 120W variety) for my as-of-yet unfinished supergun project. I can confirm that it works like a charm! If you need -5V, it gives -12V which you should be able to step down to -5V, but I haven't tested that yet.

You could certainly use a regulator such as the 7905 to drop the -12V down to -5V, a small heatsink would be recommended.

I picked up some 7905's complete with heatsinks on eBay in anticipation of my upcoming Super Gun build (I'll be using a PicoPSU as well). How do I know what pin is input and what pin is ground? These ones: http://www.ebay.com/itm/2pcs-voltage-re ... 5147783725" :think:

I'm quite the novice when it comes to circuits like these. :shifty:
