    Rising butt hinge question.

    Thank you but no,a minimum of 2.5 Volts and an absolute maximum of 3.7 Volts.By themselves they'll be fine,but trying to get four to track with each other exactly and it has a bad attack of the judders.I'd guess they are designed to run from rechargable batteries,don't know how much current they...

    Rising butt hinge question.

    These servos run at a lower voltage than most servos do,in this case just 3.7 Volts which also limits their torque.The other problem with them is the feedback pots aren't very accurate so they don't all move at exactly the same speed or park in the same place.I had to buy six to get four that...

    Ok thanks for the replies everyone. This is what I'm trying to do...... But a lot quicker than this as this is way too slow.This is done using four ultra miniature servos and is triggered by a proximity sensor. The problem I have is very limited space.It all has to fit into a tube with 60mm...

    Rising butt hinge question.

    I need to make something that works in the same way as a rising butt hinge,but I need to have some control over how much it rises against how many degrees you turn it.Is there a geometrical name for the shape or form involved,or is there anything else larger than a hinge that uses the same...
