I add the trimpot 100 k and resistor 33 K instead 56k. Sensor resisor is the same 0.47 Om.
All rest is the same like basic version. It is look like there is not current protection, - minimal adjustment is at the minimum pitch of the potentiometer and after 1/4 range current is not limited ( once Q2 was replaced - was a short circuit) It's probably PCB mistake . I have red one too from ebay (kit).
I build the same power supply a few years ago with PCB by myself and it is working for today! Great construction!
Now I want smaller version, but from ebay or banggood (red version kit) doesn't work properly.
On the movie is mistake with current point. Value of the current is 2.7 A not 0.27 A - one more mistake from banggood - bigger range of panel
