BIG thanks to ARGLaser-
he sent me some great info that made testing a Linna Lk-PD 2.0 projector much easier.

I will post here asap to add pics of the best way.

It was mistake thinking I had to open the projectors to read each laser module. You only need to do that if you wanted to see the output before losses.

Likewise with my idea of using Pangolin Quick Show to do the graphs.
^^^ not the best,
accurate or an easy way.

see the attachment below-- with a simple 5vdc power source( maybe the 5v from USB will work?) one can power up to the max output each laser inside a projector.

All you have to do is make the connection of the following pins in the db25 pinout for each color-
to test red use pin #5
for green its #6
and for Blue its # 7
the ground pin is #25 for each color.
SO for the output of combined (white) just add the numbers.

HOPE this helps---Hak(& ARGLaser)

Pics coming asap of some LPM tests and graphs on the LK PD2.0 from Miss Linna. ( A new GB for three different LK PJs is in the feeler stage ATM)

One buyer at p/L got around 625mW of white from his PJ.
