Hi,


That's an interesting sounding project.

Since the figures I always see quoted are 90-95 degrees I would say if your shooting for a plus/minus of 2 degrees then set it for 92.5 if you can.

The 95 being to top end I'm not sure you would want to design a system that would exceed it by any great margin for a protracted length of time.

If you go ahead with this I would quite like to see pics and progess if you don't mind. I have an O.N.D. in electronics sitting here doing nothing and quite like the idea of building a couple of fun herp related projects.
