pop up panel - servo? spring? any suggestions?
tony.silveira:
oh boy. the actuator with the screw that pushes out doesn't screw back in?
I guess I have a bit more to learn
PL1:
Here's a circuit that will allow you to reverse the polarity/direction of the actuator.
It uses a DPDT (double pole, double throw) momentary-on/off/momentary-on rocker switch that is spring loaded to return to center like this one.
When you press "up" on the rocker switch, it moves both throw arms (blue) to make contact and applies a + voltage through the normally closed (NC) upper limit switch (green) until the actuator pushes the keypad up far enough to press the upper limit switch and open the circuit (red) which stops the motor. Holding the rocker switch "up" after this will not cause it to move until the limit switch returns to closed.
To retract the keypad, press "down" on the rocker switch. The throw arms make contact and applies a + voltage through the normally closed lower limit switch (green) until the actuator pulls the keypad down far enough to press the lower limit switch and open the circuit (red) which stops the motor. Holding the rocker switch "down" after this will not cause it to move until the limit switch returns to closed.
You can also run it partially up or down, as desired.

This can be automated, I am using a similar circuit as PL1, except a Servo is acting as the rocker switch. I am then using ControlChoose to issue a USCCMD command to move the Servo to raise and lower my shifter and extend and retract my brake and gas pedals when a driving game is chosen. You can also have ControlChoose issue a command when choosing another emulator so your keypads would raise and lower automatically.

pl1 / darthpaul,
either of you up for some hand holding with a newb when it comes to servos? in all honesty, it seems like a different language...
thanks
