Any electronic wiz's out there?

Ed_McCarron:

Ah, the missing piece of the puzzle.  I assumed it was a USB only connection.

Where does the signal to fire the solenoid come from?  An auxillary contact on the trigger or software?

Abomination:

This is the schematic off of the website they put up for the driver



Im trying to get a plug and play option to hook up two guncon2 compatible lightguns into a molex and usb port.  It looks simple and im sure it is but if someone could combine this schematic and a female port of a ps2 into some kind of a project box for 2 light guns it would be the ideal solution.

Like I said im willing to buy a box like that (will cost less than a ps1, used or not) and someone could setup a nice little niche market for themselves.

tivogre:

Here's your approximate costs (assuming you aren't building hundreds of these and buying in bulk):

PS extension cords:  2 for ~$7.00
HD Power "Y":  ~$2.00
Wire:  ~$1.00
Voltage Rectifier:  ~$3.00
PCB:  ~$1.00
Project Box:  ~$3.00
Misc: (Shrink wrap, solder, etc.) ~$1.00

So, just in parts, you're looking at about $18.00 for the "plug and play" box you asked about.

Add someone's time rate and a bit of profit on the parts;  I think you'll see that it is NOT MUCH cheaper than a used PS ONE.  Unless you can do it yourself, or are willing to pay more "just to have" the custom solution, it's not worth it.


I couldn't make and sell one for less than $40.00 without feeling charitable.  THEN I'd have to worry about warranty, service, and customer support issues...

You can see why no one is knocking down the door on this "niche market" where there MAY be 10 customers at the moment.

In all seriousness, this is an EASY project to put together; this is BYOAC.  I'd recommend either rounding up the parts and making it yourself, or going with a PS ONE off of e-bay.

I'm working on a photo documentary / tutorial on building this (and the guncon / JPAC circuit) for my web site.

Unless you want to cut the PS2 connectors off of the guns, you will need to splice +5V and +9V into a PS2 extension cable (with one end cut off) for each gun.

The "circuit" you need is really just taking +5V, +12V and Ground from a spare hard drive connector, and converting the +12V to +9V with a voltage regulator chip.

At that point, the +5V, +9V and ground can be fed into the PS2 cable(s) for connection to the gun(s).

While the chip is inexpensive, it isn't readily available at most walk-in places. You'll also need some wiring, a piece of PCB, a hard drive "Y" cable, and a couple of PS2 extension cables.

All told, the parts can be had for about $15-$18, if you can find them, and can find used PS2 extension cables.

I thought all GunCon 2 compatible guns were USB.

tivogre:

Some guns have features that require the PS power connections to work (recoil, laser site, etc.)  Other guns won't work AT ALL if the PS power isn't connected.

They do still need the USB connection for data flow.

Notably, the "Scorpion 3" guncon2 compatible gun requires the PS Power to work AT ALL.  It includes a laser site, but no recoil, and is consistently reviewed as one of the most accurate and issue-free guns for this application.
