There are a number of things here:
1) Motor travel control will not be a problem. Like ifeliciano said, we can use a couple of limitter / reversing switches at both end of the travel. You can put the switches by the cable which are then triggered by the movement of the cable. (I will put up a diagram later)
2) The whole thing will be controlled by using a 12 channel IR controlled relay board.http://www.electronickits.com/kit/co...lec/ck1615.htm
I have looked into it and it looks very promising. It has a 38kHz frequency, which the Harmony should be able to learn. This board will be used for other things also.....
3) An IR repeater http://www.smarthome.com/83608/Chann...IR-5000/p.aspx
will be used to control the different Aspen motors. The inividual repeaters will be controlled by the IR RELAY BOARD. With the repeater stuck on the IR window of the Aspens, the Aspens will be blind to any IR command except the one coming from the repeater. More on this later.
Any remaining chanells on the relay board can be used to control curtains, blinds, air conditioning duct dampers, a STAR CEILING setup, Butt Kickers in the seats and...........
4) Regarding the mechanics, check this out http://www.firgelliauto.com/images/p...s/DumbWait.jpg
You can use the Wonder motor instead of a linear acutator.
The lift in the third photo with the drawer slides also looks promising. You can use a couple of pulleys to make that work. http://www.google.com/imgres?imgurl=...&ct=image&cd=1
5) A linear acutator http://www.firgelliauto.com/default.php
would work best for motorizing the lens.Track acutators will work the best. Another channel of the relay board can be used to control this !!!!
Enough for now...
