Need help with T2 solenoid driver circuit!

Dammit, I went out and got a 1uF cap when I already had a 1000uF!
ErikRuud:
If you are using a solid state relay, you shouldn't need the diode. There is no coil in a solid state relay, so there would be no back EMF.
Elkor:
While I have done some extensive (if simplistic) electronics in the past, and understand what you want to do, wouldn't it just be a lot more simple to have the relay fire when the trigger is depressed and not worry about the ipac led's at all? then it could be done with a simple relay or even a transistor to fire the solenoid?
Does mame even flash the led's for the gun fire or would there be a source code change as well (I have not looked myself)?
I dunno, just seems easier to make it an independent function (especially as it is specialized equipment (T2 guns) anyway).

Looks like you're making good progress :D. If you need any info from the original coil driver board like schematics or transistor part numbers let me know. I'm hoping to do another small run of pcbs in ~4-6 weeks if you get something working well I'll run off a few and send you one.
