Charles: Yeah, we're building custom drivers for the solenoids and we built a 30v power supply as well.

I also just ordered a Practical Maker PWM shield for arduino UNO. 1
shield
gives you 32 pwm pins and they're stackable, up to 6 without the need for an external power supply.

Beware that you'll need PNP transistor for the power stage, or you'll get small bumps when the TLCs go BLANK each cycle.
