Sadly, no I haven't taken the time to finish it up.
I do like that controller option though. That would definitely make the electronics side of it easier. However, you would still need a way to only power the actuator for a second, or you'd burn it up.
As a side note, one of the guys on ecorenovator used a similar one to convert a freezer into a super efficient fridge aka freezerator.
