+====== Description ======
+A nice linear move is sometimes a bit difficult to construct.\\
+Since a 3D printer has become a common thing in many workshops (also mine!), \\
+this option gave me a good idea how to construct a linear movement with a servo.\\
+Allthough... it is in fact a bit more complicated than just linear, because the movement \\
+starts slow, get a bit faster midway and slows down again at the end.\\
+The full required move for this standard is 6 or 9 mm depending on the size of the used excentric.\\
+More over the mechanic solution in the servoset2 [[servoset2|here]].\\
+But to move the servoset2, a servomotor and servocontroller are needed.\\
+And that controller can be this GCA224, with some extra options.\\
+===== Featurs GCA224 =====
+  * Two speed selectable for turnouts or signs(or railroad barriers)
+  * isolated command input max 5-12V from anything that has to activate the servo (can be a simple switch as well)
+  * double output for leds
+  * easy programming of the PIC12f675 (can be altered to your own desired task).
+  * switch to swap the left/right position from command input
