just one question you know the bit where you gotta glue the pot head - it is actually unnecessary. why would you bother holding it in place when there is nothing that is going to move it any way?
Ive had this happen on two occasions where the pot head slightly shifted itself, messing up the servo centering. This is because the pot head is extremely sensitive to even vibration. Considering Ive used servos a billion times already its pretty rare, but possible. A small dab of glue cant hurt, and if you want to remove it, you could always dissolved the glue later with like acetyl alcohol . . . But even then, if it does happen, you could just simply tweak your code or reopen up the servo to fix it . . .
what are the maximum and minimum pulse widths for modded servo?
this is different for almost every servo type, and even sometimes varies within the same type of servo. usually its between 1ms and 1.8ms. to find out, i just run a test program that slowly ramps up the servo speed while outputting the speed value to my laptop with hyperterminal
. when the servo stops changing speed, thats when its reached the maximum. most of the time tho im just too lazy and guess until its satisfactory.
what would happen to the servo if i go out of the max/min limit
nothing bad would happen to the servo . . . usually it would just lock/freeze up at some value. depends on the servo, if its an analog type or digital type, etc.
