Possible to use a coin mech with no power?

[cRckls]

I've switched to using a small nettop pc (aspire revo 3700) for my mame cabinet as it's a bit more powerful and I wasn't using it for anything else.
Previously I wired the coin mech to a spare molex connector on the pc power supply, but as the nettop uses it's own power supply, I can't do this anymore

The coin mech I am using is this one - http://www.arcadeworlduk.com/products/Comparable-Coin-Mech.html

I'd rather not have to run a separate 12v supply just for the coin mech, and I'm not fussed about it recognising correct coins.
Does anyone know if it's at all possible to wire the coin mech up to the ipac and still have it trigger by bypassing the detection?

check to output chute area for screw holes. you may have (or be able to) place a microswitch with a wire trip onto the side and just use the mech as a size comparator. your microswitch can feed back to your encoder.

Otherwise just switch your mech out to a standard mechanical style, no power needed at all.

I'd try feeding it 5VDC from one of the USB ports.  It may still work.

Thanks guys. I figured out a way to attach wires to two points that will trigger it mechanically. I did try it with USB power but it wasn't enough to activate it.

the mech probably runs on 5 volts, but the regulator (likely an LM7805) requires a minimum of 7 volts to properly run.
