I know this question isn't directly linked to the BASIC stamp,
but I am doing a robot project (with the bs2.p) and need to get a
servo that does at least 180 degrees. When I have gone to the hobby
shops they tell me that almost every servo goes about 180 (note the
key word there "ABOUT"), but then I find that, that is only if you
are stretching the limits of the servo.
Does anybody know of a servo (preferably small) that goes 180+
degrees? I need it to be postion controllable also, so I am not
looking for one that has been stripped of the pot. Thanks!!!!
If you can build it yourself, you need to add a couple of different
sized spur gears (one to the servo output) to produce a rotation angle
greater than the servo shaft. (bigger on on the servo shaft, smaller on
a new shaft) . If you can't build it yourself, then look for a small,
say ~2:1, model railroad or model car, reduction gearbox and drive it
backwards.

If servo torque is a concern. then a 2:1 might be to much...
Suppose you could at least get 150 deg, then a 5:4 ratio would
bump you up to 187.5 deg with a minimal loss in torque.

try searching for rc sailboat servo. I have a capstan servo that does 3.5
turns stop to stop. you should be able to get 180 out of that but I dont how
much resolution you need.
