Ascom focuser

[Marc1980]

I have just ordered a skywatcher motorised focuser. I would like to control it from the pc by building my own device that does this http://www.firstlightoptics.com/astronomy-cables-leads-accessories/hitecastro-dc-focus-controller.html

I feel confident in building one if someone were to point me in the right direction. I have searched for it but I can't find one where it is added to an existing focuser.

If anyone could point me in the right direct that would be awesome.

Many thanks

I use the SW kit its only A dc motor so its not auto focus, it have 4 set point I use 1 as all the way in and 4 as all the way out , 2/3 the set for stars ect so if you push 2 it will move out the focus

 and them fine ajust on stars . recheck every 15 min just to see if focus have moved over time.
