GunCon2 on PC-monitor
<< < (24/42) > >>
Silver:
The chip basically divides the horizontal clock frequency in half, and generates a composite sync signal from this. You feed it the seperate horizontal sync and vertical sync from your VGA graphics card (usually by cutting up a VGA able or using a VGA->BNC cable) and use the output sync on pin1 to feed to the composite video connector attached to the gun.

Andy has updated the wiring diagram for this application on his site, tying pins 2 and 4 to ground:



I'm not sure if this will solve your problem or not, but it's worth a shot.

@Silver:
Thank you. So basically, divide the 31KHz to 15Khz and make a composite sync... Oauu! Only one chip to do more than the circuit i built to connect the guncon2 to my old TV/Arcade monitor! (The same circuit that Tivogre posted previosly). :o

@Tivogre:
Thank You. I'll try it. The capacitor is also diferent: 16uF->100nF and i don't know if is electrolitic or not.
BTW, which is the link to the page of Andy including this circuit?

Thanks again,
tivogre:
The link is:

It's just the picture I posted.

Call me lazy, but does Andy plan on selling pre-wired Guncon to PC chips? With shipping from the UK so expensive I'd almost rather pay extra for a finished product than going to my local shop to get the needed capacitor and resister and deal with soldering again.
