GunCon2 on PC-monitor

<< < (22/42) > >>

Silver:
Quick bit of info:

You don't need a JPAC - you can order the chip seperately from ultimarc directly. Its the "JPAC small chip" from the upgrade page on the ultimarc site:

www.ultimarc.com/upgrade.html

I think it costs $8. The circuit for wiring is shown below. 680R is a 680 Ohm resistor, C1 is a 10 micro farad capacitor (rated at 16V). All the grounds from the syncs can be wired together.

Silver:
Note while I've had mine working, I'm still testing and have not always had it working 1st time. For the record, I also added some extras to the above circuit to smooth out the output a bit when I could not get it working. However, it was not working for other reasons it turns out.

Andy from Ultimarc has had his Namco2 guns working with the above circuit.

Here's my board (ignore everything that isn't around the chip - thats a couple of other circuits to smooth the output and also to give me a regulated 5V supply from a higher input.)

tivogre:
Anyone know if this device:

...would work to get the VGA sync signal for the gun.

Looks like it has a VGA pass through and simultaneous composite output.

Shouldn't this work?

It costs about $80.00... one of these and two guncons is still cheaper than 2 ACTLABs.

dabone:
That shouldn't work because it's a frame buffer that re-renders the signal to meet the output independent of the input (i.e. the sync won't be the same)


Later,
dabone

jelwell:
Silver, congratulations and thank you for the circuit.

Hmm, should I hack one up now? Or does anyone know if Andy plans on selling a kit? I am both handy and lazy, but mostly lazy. ;)
