B50 Powerlight 660nm Build

[LaserEmperor]

and i want to run it on 1 or 2 18650 li-ion batteries

 

[Fiddy]

you've got lots of reading and searching to do then, this forum doesn't spoon feed newbies.

 

[LaserEmperor]

just need advice on resistor, then im set for my first build

Just ordered the host!

Got my LPM back, heres the power graph:

Wow, VERY nice build there buddy

 

[Wadeheat]

wow, it is really awesome, how long do you finish this?

Such an old tread, but sweet build might have to give this one a try.

i finished this in May 2011 lol

Its still going strong, got a custom focus adapter on it now

 

[awillis2589]

Nice, what did you have the current set at? I was thinking this would be cool with one of Moh's new focus adapters and some red gitd epoxy in the grooves.

 

[Fiddy]

not sure, something conservative, its only making 260mW

I am doing a very similar build to this, how did you test the diode before assembly, simply attach the batt+ to the +FlexDrive ? No need to worry about the negative with this driver ?

He connected the negative of the battery to the black heatsink somehow and continuous negative comes into play.

But when you assemble it.. the case acts as the negative and runs through the heatsink, through the diode wires and into the flexdrive. The diode negative and battery negative are connected. You can use a continuity test on the two 'connectors' and it will beep.

If you look at the flexdrive manual.. It's the top wiring diagram.
