We started with this test circuit on my bench.
Values of resistors are not critical, they can be anywhere between 100 ohms and 10 kohms.
I am already using it on my focuser (with optical encoder - because I had couple of them) as a laptop-free alternative to my small application (that I posted some time ago on this forum).
It should be noted, that the smaller the resolution of the encoder, the finer positional accuracy of the focuser will be.
(My optical encoder has 96s/rev, and this gives me just about right transfer ratio) |
Cheers bojan, hope mine turn up for next weekend. These rainy day projects are keeping me busy to say the least lol
