hello i have a question i got that home made laser driver and 16x laser diode it was working fine like 4 month with lipo battry 2 cells total of 7.2v and i tought about connecting it to a Transformer of 8v and so i did well my question is why my laser diode died after 1 min of using it. and...

hi ive build an laser driver from this site the 1 with lm317 at first it was working just fine with current set to 330ma but now i was just curious so i decide to check to voltage and ma well it show that the output voltage is not 3v its between 6-7.5 volts isnt it should be 3v? and second...

i have built an driver from the diagram it working and i can adjust the current the battery i am using is li-po 7.2v the diode working just fine but my problem is that when i measure the volt it shows the battery volt it shows like 5.5-7.5 volt out why its not regulating it to 3v? i am using...

ive got an x16 nec dvd burner diode its a closed can well the problem is that i set the current at 430 ma and the 1st problem is that it dosent getting evan alil warm(which is weird) it stay cold all the time even after 2 minutes and second which is the major problem it dosent lighting up a...

hello ppl i got this x16 dvd burner ive connected it to the driver and i give him 250ma its burning black things but its not lighting any matches i think its an open can diode the beam is kinda bright i can see the beam all the way to the point(which is cool!!) my question is there any1 knows...

i got and dvd burner called master write or something like that my driver output current is nearly 400 ma(390) and when i connect the first diode it works but the light is very low on max current so ive tryed the other the other have produce more light but still low light any1 knows what the...

is there anyway i can see the beam like i see it in the green lasers? cos in the red i only see the dot in the wall and i wanna see all the beam without smoke or something like that is it possible? or im can just keep dream about it? thanks
