The 5K pot provides the feedback to the panning servo.
Servos have a 5K pot in them, it tells the servo where the output shaft is pointing so it remans proportional to the stick position.
There are a few sites showing mods to servos.
Ill see if I have the URL somwhere.
As far as pointing the CCD through the viewfinder we have some testing of lenses to use going on at the moment, not the thread on it in here.
Currently I am about to test a 5.7mm lens we got from a company here (who led us to beleive it was free sample then handed me a bill for it, frigin curry puff.)
Ive tried a 4.8 mm lens for the mini camera but its still a bit small
Julian has a 6mm focal length lens that is the right size with a little overlap, hoping the 5.7mm macro lens will be spot on.
Keep an eye on the thread here on it Ill post a shot from the viewfinder when I fit the 5.7 lens to see the results.
If you dont have a mini camera yet wait a week, once you know the lense size you need you can go bargain a 5.7 mm into the camera deal, they come standard with a 3.6mmm lens.
Unfortunately most optional lenses are 2.9mm wide angle which not what we need for the viewfinder.
Anodised, hooley dooley !.
A word of advice there, if you are making your own rig be prepared to do some mods and changes to it as you go, there are things that become apprent as you use it that you will want to deal with that might require some structural changes, anodising, milling or casting and the like of parts might be wasted until such a time your refined the rig and stopped making mods to the construction.
Id hate to see your anodised bits looking like a swiss cheese from mods to it.
But if you work in an Anodising shop then yeah do the lot anytime.
My advice is start out watching your budget on it, in time it will blow out somewhat as you want better or more so keep some for later and dont get too flash with the cash to begin with.
Secondly when you buy some stuf you need to modifiy sit back and take a breath before you hop into it, things like this can cost, I fried my monitor outsmarting myself and blew $250.
