Found some results for the H55N here on LPF. Now I only need to identify the visible one. There are 2 diodes in here. Be posting soon with more results. Before testing anything... or frying anything, remind me again, DVD-RW red laser diode right? so, if I have two laser diodes inside the...

Thanks, I'll be cheaking the diodes compilation thread to search for them. DVD-RW Models are: LG GSA-H55N and LG GSA H54W I'll be harvesting the diode tomorrow and let u know more then. Also, I'll run some searches on the models numbers, and further searches if I get more information from...

DVD-RW Models are: LG GSA-H55N and LG GSA H54W I'll be harvesting the diode tomorrow and let u know more then. Any specs known on those? So the pot is not needed if you already know the output ? And/or to use multiple diodes from the same driver and change the current ?

Hi guys, im getting a couple of DVD-RW DVD-RW Models are: LG GSA-H55N and LG GSA H54W I'll be harvesting the diode tomorrow and let u know more then. I figured ill be building a DDL driver LM317. First option: DIY: How To Make A Laser Diode Driver Circuit - Video Second: Laser driver - It...

Hi guys, im getting a couple of DVD-RW diodes, how do u find out the mA of a laser diode? or is there a chart for every laser diode chart? does it depends on the output mW ?

For the price of a 14500 i get two BL 5C cellphone batteries. Did a little research: 14500 3.6-7v 900mAh vs BL 5C 3.7v 850mAh (got the specs from nokia.com) If u got a compatible charger, o even a cellphone to recharge em (thats my case) the BL 5C is the way to go.

Surely its been mentioned before, but i'm thinking the easiest way to get 7.2 and not going for the rechargables standar batteries is to get a couple of 3.7 cellphone batteries. Only drawback its the custom conections u gotta do. But they r rechargable as well, quick, and really space friendly.

Thanks man!, been reading a lot, index really helps.

Hi guys, i've been reading a lot, almost ready to build a LM317 driver. I've got some DVD-RW diodes. But the LM317 driver requires 7.2 volt input, getting that from AA rechargables implies getting five of them toghether.... I was thinking, is there any 3v driver that can be built from store...

Hello ! So, its been a while since I came up with the idea of using some cd or dvd player laser to make my own laser pointer. What a surprise when I started searching for information and discovered that it is a well known procedure. That being said, I found mysefl with two dvd RW ready to open...
