EDIT: Apparently made a post while I was blacked out drunk last night... I got it working Actuator sweeps from 0 to 100%, Video coming soon. I lost my cell phone at the bar the other night so I gotta borrow a camera..

used the webcam on my laptop, so the qualitys bretty bad...
UPDATE: Found out I used an undersized 3.3V voltage regulator and fried the ethernet controller when it failed short-circuit.. Was also having issues with the 3.3-5v level shiftter at >16MHz, so I decided to do a complete redesign for v2.0.. New board will be fully 3.3V and will use a microcontroller with integrated ethernet. Reusing left over PCB, so new board is approx 3in x 1in.
Also discovered that the actuator responds fine to both 12V and 5V PWM signals, and erratically to 3.3V PWM.
