Hi all,
First question:
--------------- being a citizen of an european country I do not know much about the US threads standards for screws and nuts. As I have to use them from time to time, I wonder if some of you guys can make some light on the different non-metric systems. As far as I know, there are three basic systems: UNC, UNF and Whitworth. I've been told the last one is almost abandoned, and I often come across definitions of screws without any UNC or UNF before. Does this mean that one of these systems is more used than the other, that it's not needed to mention it? Are there any tables of these threads available on the net?
Second question:
---------------- Is there anybody who can point me in the right direction to find an RC Servo control circuit which can be used to move a servo by an altimeter?
Thank you in advance for your help!
