Today I had time to continue led build. Now was the time for some screw driving and soldering.
Leds screwed in with nylon washers and Arctic Silver thermal compound.
Wires soldered.It was hard to solder because the heat transmission to heatsink.
I decided to have 4 channels for leds so extra channel for green led. I tested the led strings with buckpuck driver and everything was ok. Still need two more LDD-700H drivers to continue this build (waiting items from fleabay supplier).
Next phase is to complete drivers board. The driver PWM controller board and software is ready and I will post blog about it when its closure build is completed.
