HBTU9992

In the foreground to the left are the +5V and ground connections for powering the rig.

In the foreground to the right is a board labeled "Koltech MD3110 module board V1.0a."  Coming out of this board are the two +5V lines to the motor.

In the middle is another board with a chip labeled  "AMIC      A29L040L-701     1053011     AML0099"

In the background is a white motor with four cables coming in from the top and two from the side.

This is an image of the oscilloscope when it is connected to the two +5V lines, 2a and 2b.  (Note that the oscilloscope's voltage scaling is off by an order of magnitude).

This is an image of the oscilloscope when it is connected to the two oscillating +3.3V lines, 1a and 1c.

It looks like the green/blue & red/orange wires are going to switches. As the motor turns does something trip the switches? maybe they count revolutions. The motor is probably using just 2 wires (5v)
The MD3110 might be E-San Electronic's dc-to-dc-Charge Pump Voltage Converter.
The A29L040L looks like its flash memory.
