Another 3h spent in drilling and soldering. The stepper and the 400rpm DC motor arrvied

Here's the ULN2003 driver just next to the laser driver. Above the LM7805 with its cooling unit. All cables will be attached at the end.




The Nano has all its necessary wires attached. Screwed to the bottom and USB is now pluggable from outside


This will be the final position of the DC and stepper (the stepper mirror is not adjusted yet)


The 400rpm DC motor with its mirror glued


And here's an updated version of the Fritzing schema

Here some updates:

Part of cabling soldered on the Nano. D13 Laser TTL, D12 Servo signal, 5V and ground


More stuff in the box. The small yellow board contains an 7805 voltage regulator to have 12V and 5V


Still waiting for the stepper and the dc motor to continue the work.
Additionally I am thinking about driving the DC motor through a PWN and transistor to regurlate the speed.
To calibrate the stepper mirror at startup I am thinking about an attached phototransistor on the side.
