This ones for all of you who either want to have arcade recoil for console or just a fix for broken gun drive boards.
Based around an Official Namco gun, ps2, Time crisis 1 pcb, guncon 1,2
Ive tested this with a timecrisis1 PCB and a heaps of ps2 ligh gun games.
If your using this fix for arcade use, it will completely replace the gundrive PCB, which can cost quite a bit and be a **** to find. :mad:
This is around $5 of components. and a little time. ;)
Normally people would just add a 5v switching relay to the gun but if you keep your finger down the solenoid stays engaged.
It just doesn't feel right at all + it stuffs around with the optics 5v feed. sends the target all over the place :wtf:
This seems to only be a problem with arcade pcbs, a guncon 1 can run fine with just the relay, no optic interference,
but the solenoid will still stay engaged with the trigger pulled.
So i decided to build a 555 timer with a pot to tune a pulse for the recoil. 8-)
Here's the circuit

and heres a video of it working perfectly.
Namco gun recoil running off 555 timer. (http://www.youtube.com/watch?v=-SWsk0CLSNM#ws)
I must add i made this circuit with the help of alec-t on http://www.electro-tech-online.com (http://www.electro-tech-online.com)
He designed the original and helped me tune it to this.

Very cool! So how would this work in a standard guncon 1? (I am building a PS1 lightgun cab and if it was within my limited technical capability to add recoil, I would love to).

open up the gun con1 and remove the optic sensor.
one side of the sensor is ground, the other is +5v.
run the ground wire on guncon optic to ground on the Namco arcade gun.
run 5v wire on guncon optic to +5v optic on Namco arcade gun, and also the 555 circuit.
Run center wire on guncon optic to optic wire on namco arcade gun.
find the trigger switch on the guncon, one side is ground the other is +5v.
wire the trigger +5v to the namco arcade gun trigger wire, and also to the 555 ground.
there should only be 2 wires left coming from the arcade gun, thats the solenoid power, wire that up and your done.

Final revision, now with rapid fire switch.

Do you have the circuit diagram still? I want to try my hand at this... the pic seems to have gone off the thread.

So my Time Crisis cab screen died and i decided to dedicate the gun to PS2, If anyone else decides to do this make sure to get the 5v feed for the sensor from BEFORE the guncon1/2 board.
Also put a diode coming directly off the guncon board trigger wire or the 555s wont discharge fast enough.
Now i need a second one for Vampire night XD

Sorry if this is a bit of a thread resurrection -
I'm interested in building at least the single-shot portion of your circuit for a solenoid gun, syntax_x. But I'm a little confused by your capacitor markings. Are the ones marked 470n, 470 nanofarads? And the ones marked 10nf, does that mean 10 nanofarads or microfarads?
If you see this, thanks for any help!
-
Yo, the 10nf is one of those little round orange ceramic type ones dont even really need it hey..
the 470n are a squarish safety cap.
if you do wire one up use the guncons original lazer diode and circuitry or youll have issues calibrating.
-
Sorry to bring this thread back from the dead, but this is the only thread I've found online which does EXACTLY what I want to achieve - Namco recoil with a ps2 for single shot (time crisis, point blank) and rapid fire (crisis zone and time crisis 3)
Has anybody been able to complete the same thing as syntax?
I've recently acquired a Namco gun and have no idea where to start.
I've also got a guncon2 that I'll be using for the mod. I'm decent with a soldering iron, unfortunately I'm horrible at electrical diagrams.
Don't even know how to power the solenoid. Not sure if it works.
Any help would be appreciated

Resurrecting this in hopes of some more input. I'm on the same mission. Recoil on gcon 2 would be awesome and I was wondering if anyone has done this here successfully?
