Re: Meta Topic : Pinout & Performance of actual LD I don't understand this graph. can someone explain plz? why does Amps goes with Volts?? and why Watts is on the other side?

line 13th ur infinity mean high ohm right? thank you for info i get it a lot now my DMM dont have diode check, it the dial kind(needle pointing to number) are there another way to check if it burned or not? thank you very much

wow oh i got it now another question how do i check that diode is burned or not? what is the resistance should be when it's still good and burned? and some laser diode look exactly the same but - and + might be different how do i know that ,so i wont burn another one T_T

how much? i dont have money im 15

Arggg:confused::confused: it's ok now i saw little metal thing on my laser and i try to pick it up and i broke the glass thingy by accident :confused: can u help me with my other laser? my driver is 12.5-230 mA and 7.5-7.5 V why my laser is not bright? or that's the brightest it can be?

no it's all like that when i open and it's doesn't look like anything has been broken away i dont see any part of wire that should have left when it's burn out (see with my microscope) and my"try them all" i tried by using that thing that use to measure ohm (idk what's it called) b/c when i...

this is my old laser and couldn't figure the legs out so i try them all, and it didn't work:confused::confused: i measured ohm and they all connected to each other i open it up and got some pic for ya:undecided: can u tell me which leg is - and +??:bowdown::bowdown:

i cant make video so i take some pics my driver connect with regular LED and turn pot to MIN and turn to MAX then connect with my laser(old one) and turn MIN and MAX now i know that it's IR diode and some pics it wasn't bright at all is it should be brighter than this?

the first one is 4 legs IR and red LED diode and i think i burned the IR i got it from DVD player and i know it's weak i turn my pot to highest but it it's still shine only 1 cm away. i will upload the video

my other 2 is regular red LED the first 1 on http://laserpointerforums.com/f42/meta-topic-pinout-performance-actual-ld-26417.html what is the mA that i should use?

I tried with my 2 other laser and it work, BUT it wasn't shine very bright. Light just came out for 1 cm that's all. -*- I measure my driver's V and ma without Testload and i get range (adjust with my pot) ~7.6-7.6 V and 12.5-250 mA is it only 250 mA or it's support to be 300 up?? i will make a...

I cant T_T i think i accidentally burn out the IR and Red is still not working i will test my driver and try with other first and i will know that my driver is wired or that laser. thank you for reply PO

i turn it on in the darkest room and shine it to something black, but my cam still can't see anything except at the laser diode.

i read it for like 3rd times now but i still dont get answer that why it's so weak i gonna try to make load test and try with my other laser thank you for link

why green laser diode doesn't exist??

i made my driver and it's exactly like this. YouTube - DIY: How to build a laser diode driver i test it and my laser wont come out the, i try IR and my camera can see little purple light and i wasn't bright at all, then i see little tinyyyy red light come out when i testing IR then i think i...

i got it now btw some other ppl say AC some say DDC thank you very much jerry

I have read it and thanks for the link If I put in high Volt battery in to my driver, what is gonna happen? is it gonna burn my laser? and if i use 100k ohm instead of 25 it just gonna be hard to adjust right? sorry for post on the wrong place I am new

I am new here and i confuse about transformer and resister they both change the Volt of current but what is the different??? thank you for reply

my driver is everything like this one DIY: How To Make A Laser Diode Driver Circuit - Video but i use 3362 trimmer for pot and i think it's 100k ohm this is my guess i use 9v battery so maybe it's too high and my driver cut it down it's just my guess i am noob thank you for reply
