Looking good mate!
Nice job on the DIY PCB
Frickin sweet! How much did the whole thing cost you? Looks great as well.
Really cool. How did you make that circuit board?
THX ARG!
THX crazyspaz!

cca 100 €
this is quite a lot but still worth it. Great work on this.
In general you can build it for less than $50. Mine was around $30 but i had some parts already around like a cpu heatsink.
Very nice DIY LPM! :gj:

I just wounder how you calibrated it. What did you use for calibration?
Hm, unless you got them metered elsewhere with a calibrated LPM the assumed power isn´t a good value to calibrate a DIY LPM. 1.6A in doesn´t mean you get 1.6W out. The output can be somwhere between 900mW and at best 1.6W. All depending to the efficiency of each diode, the optics and your batteries quality.
You better build a calibration tool like I did or get your lasers metered with a calibrated LPM by using a lab powersupply as the power source while they get metered.
How to prepare calibration tool?
