Figure I might put the DMX servo driver we manufacture on sale for a bit..

Sale price, $45USD plus shipping, thats 25% off the normal retail price of $60USD on the store

This makes a easy cheap actuator, for either beam steering, or drop down gratings. Servo not included..

See DZ's great review here:

While I was at it, I thought I would drop the price of our other boards as well by 25%
