Any one got any ideas for how to trigger a 350v capacitor with an arduino in the smallest way possible?
I was thinking something like a transistor or a mosfet transistor that would'nt need to many volts(probobly 9v max).

I have been playing with 1200uf 400v capacitors to create an electro magnet that is only on for a split second. I use a disposable camera as the charger and put a switch between the positive side of the capacitor and the coil wire. charge the capacitor bank and hit the switch. I use a 30 amp switch as the "trigger" which works great.
Hope that helped

Sounds to me like you are trying to make a coil gun?
Dangerous stuff. You might like to rey a lower voltage version of one like this: http://www.doctormonk.com/2012/01/diy-coilgun.html

I'd suggest an optocoupler triggering an SCR which fires or discharge the capacitor.
Since you've suggested its a 350v capcitor, we can only assume the voltage on it is 300 something volts.
Be sure to use high discharge capacitors, such as found in flash guns.
