Thanks Everybody!!
1. Ok it says to measure across the resistor so in other words the two solder points on the resistor correct?
2. it says one mV = 1 mA so how exactly would one Measure a mV using a Multimeter all I see is V. mA, AC V, DC, and Resistence
so Im assuming that V. mA is what I'd use but if so isn't that just a Volt and wouldn't it be impossible to see 32 mV because a Volt is a thousand mV's?
ok so basically I get the Driver the, diode, test load, solder the the Test load to the Driver, disconnect the Red solder apply solder to the Blue solder pad, connect electrical source, test voltage with Multimeter across resistor, change mA with pot on the Driver till correct mA, remove batteries. Use the short pad on the Test load to remove electricity from driver, connect driver to diode and test to make sure it works? then fully assemble?
bleh to many commas
everytime I read the next post this project becomes more and more complicated!!! and more expensive!!!
Heh, gues its my turn to help.
1. Your first question is confusing to me... I could probly understand it if you worded it differently or added a picture (a cheesy one done in ms paint should do). The resistor you mention, are u referring to the test load?
2. 1 mA is what current you are giving your diode. 1 mW is how you can measure how strong the beam is that the laser is emeting. 100mw is pretty good for a blu-ray, and depending on where u live u should be able to see the beam at night or at least very very dark areas (I live in San Diego which gets less then no rain, which means there is always dust in the air making my current 100 mw green laser exremely visible... although your eyes can pick up green light much easier so blue, rather violet, wont show up as well). Using the 1mA to 1mW would mean suplying your diode with 100mA would resort in 100mW of output power. HOWEVER, I personally think wherever you got that number is a bit much... 120mA would probly give you 100mW.
K enough ranting on Q2, the cut to the chase answer is, power your diode at 100mA, if you can't see it bump up the power to 120mA but no more, you don't want your diodes life expectancy shortened.
3. (k well u didn't have a third question, but you did have a third paragraph) That seems about right. Have you seen Kenoms short video on how to do all those steps? It's very helpful:

Although I'm not sure if your using the Dorcy flashlight as a host, its still helpful to watch. I'm asuming youve also seen the post on how to install this very diode and driver into a dorcy considering you posted in the "tutorials, Help & Repairs" and thats where the instructions are. If not heres a link:

on question number two you think im referring to be able to see the beam when I am talking about how it would be possible to see a slight movement on normal multimeter seeing as a mV is 1/1000 of a volt were talking about the smallest movement of the pin. so how would one determine the actual mV on a Multimeter?
Thanks for the Videos they are very helpful!
The guide is Also helpful except no one explains exactly how to use the Lava Driver not even the pdf Guide on Dr.lavas site is Very detailed on it. well maybe it is but not from a First timers point of view.
