Potentiometer, PIC 16F..., LD293 H-bridge, RS232 level shifter and some other minor stuff. The main intellectual property lies in the firmware.

ZABER translation state - the magnet

I had to shift the magnet, as the new position of the motor (bad mounting thread...) had shifted the lead screw horizontally. Homing didn't work anymore, as the hall sensor was 'blind'.

Problem 1: The power jack was broken
Problem 2: The magnet had fallen off and homing didn't work anymore.
Problem 3: The thread on the stepper motor (plastic) is pretty worn out, so I ha had to shift the motor.

My LAST perfboard prototype

|
And this is only half done...
I wonder why I get myself into such tedious work every now an then. Sometimes soldering is ZEN-like, sometimes just a pain.
