Thanks Neale,
Meanwhile I have soldered everything as per second diagram.

Now i wonder how to test and adjust everything without burning my BOB or the laser driver. I still dont have the diodes. It seems i have to install the program and start from there.

I still don't understand what these pots do. The one at the output seems to adjust the max voltage output, right? I mean its still not clear how to adjust them.

I am frustrated at the point of freelancing sb to make PCB drawing and even revising all and making me a PCB where double laser driver and this is integrated in one so its very simple to connect and operate. Not sure if there would be enough public for this but i am ready to jump and sale it slowly later or some kickstarter campain.
