so what is 3rd pin there for?? /according to Sam`s laser FAQ, it COULD be a PD... I measured mVolts at pins when shining flashlight into LD, and voltages matched Sam`s description pretty close :-? / I will have to risk those dvd LDs, as shipping from US to europe is waaaay over my bugdet...

hey guys where could I get DVD LD power ratings? I bought 3 broken 16xDVD burners, to yeld some nice LDs, just waiting for post. I toasted 2 DVD LDs by unknown [smiley=cry.gif] [smiley=cry.gif] [smiley=cry.gif] way (I use DDL`s driver), and I want to avoid frying these new pieces. Is there any...

yeah, but Im thinking of another way to discharge cap. I powered on/off circuit without LD, and cap held charge which killed LD after I connected it.

hey guys, any ideas how to discharge end capacitor after power - off [smiley=huh.gif] ? I mean placing a discharging resistor across cap, or to use dual switch for power, AND shorting cap :). would that work? . I blew my LD by forgetting to discharge that damn cap :(

My first LD died @ much lower voltage and current. driver is OK. so I cant understand what was wrong. :-/ bad luck I cannot get any more LDs coz of their price :'(. and I should save some cash for DMM, this one sucks >:( guys, is there any use for DVD reader LD or DVD burner IR LD? got couple...

well, Im done... have no idea what happened, LD just dimmed into LED i gues... >:( >:( >:( faulty capacitor? I dont think I screwed the circuit, but thats my second (and last one) LD that passed out [smiley=cry.gif] [smiley=cry.gif] [smiley=cry.gif] [smiley=cry.gif] [smiley=cry.gif]. and that...

heatsink hello. I found a nice heatsink for LD modules. Made from transistor hatsink, just drilled hole bigger, to hardly fit module. I think that only half of heatsink would be sufficient, I just had no time to cut in two :) IcE

low power? hey guys. how come my laser cannot burn anythig? do I need optics to focus beam into single point? I ripped 16x pioneer DVD burner, built daedals driver, put LD into collimating module, put it into heatsink, hooked to the batteries.... I find it weak. no match burning :(. it just...

"Maybe you could(if you'r bored) build a potential divider across the 3xNiCd batteries?" what you mean by "driver"? :). I have lots of parts lying around, except that damn lm317 >:( >:( >:( ;D ;D ;D ;D sorry. I know what divider is, but cannot figure myself how to connect it (i mean resistance...

so collimating lens from cheap pointer? :-? im just fu... very :) courious if LD works or not, I am goin to make 317 current source next week. i hooked up like 12ohm resistor and 220uF :) cap, and output is next to nothing. without resistor i can see a red diffused thing on the wall... picture...

theyre not AA batteries, but NiCd cells, being 1.2V each, not 1.5 as batts :). (dont have batts) and my measurment : +accu -> DMM -> LD-> -accu :-? anyway, i guess my DMM is dead [smiley=undecided.gif]. and what about that collimating lens? where to get them?

not a feint glow, its pretty intense :). dont have lm317 yet, is there any other way to power LD (to test if it lases or not) ?

need help hello guys. I need some help [smiley=cry.gif]. I just got pioneer 16xDVD burner, and took out LD. I connected it directly to 3xAA NiCd cells (I measured 3,8V and 122mA), but all I got was red diffused glow (LD did not get hot). Did I blew the LD? Or do I need some optics to make it...
