Help me start on a small blue burning laser.

Hi,

This is a forum full of intelligent people! I have no experience in building small DIY burning lasers but I'm very eager to learn how to build a blue/violet one; and from what I understand they're not too different from red ones? I have a few questions.

1. Blue diodes are expensive for me, especially the phr-803t ones. Should I be worried if I just buy one? I am thinking of buying 2 sleds from the group buy thing going on over at the group buy forum.

2. So far, the parts I'll need are: Blu-Ray diode, a driver (no clue which one), Aixis housing and a 9V power supply. Do I need anything else?

3. Do I need safety goggles for the phr-803t diode?

Thank you so much.
 





Or you can buy one of mine :P ;D click my sig, I have links and a semi-detailed explanation of one of the many possibilities...
 
I am not trying to buy premade ones, but I do need burning lasers so I'm not sure if 70mW is enough? I was looking more for 150 to 200mw, unless all phr-803ts are 70mw and the drivers make them even higher powered?

Questions are still in the air, thanks.
 
70 mw will burn also just focus it correctly + it will live a long long time at that ma usually ;)

if you making your first better buy a couple of each cause its like a lays potato chip cant just do one

prh 803-t anywhere from 13-45 bucks depends on who and where its bought

flex drive if you want to run it at 3-5.5 volts groove drive or rckstr if 7.5 to 9volts is used

i personally prefer the rckstr drive but kenom might have a few groove drives left

or like Ace said first buy a complete one professionally made by him and skip the headache and

possible heartbreak  ;D
 
I am not looking for a premade one. I am trying to get the experience of building one myself and feel that I might as well buy something from dealsextreme if I was that lazy to not make my own. I'm not worried about the headache or heartbreaks.

Thanks.

Its clear he wants to make a circuit and extract the diode on his own. You can build a DDL circuit and use a 9v battery. Make sure your careful when extracting though, TAKE YOUR TIME!!

heres a video of how to make a DDL circuit (you can make it smaller) --> http://www.youtube.com/watch?v=BI7iuBze5I8

You might want to look at this video even if you can already solder.

PM me if you have anymore questions. Also, you know that its violet and not blue right?

I did not know the 803t was violet. Thanks for the information. I appreciate little things like that.

To be honest, while I don't want a fully made one, I do want some already made components, such as a rckstar driver because I want to hook it up to a 9V. Also, I am not extracting the diode since I don't have any blu-ray drives at home, so I will be purchasing two of them from a group buy.

A) What is the mW for the 803t?
B) How much current should I ask the seller to preset on it (I want to burn, life span not too important).
C) Do I need safety googles?

A) See power graph for a rough estimate:

B) Dunno
C) Yes, for anything over ~35mA or 5mW. There's a GB going on for these now too-check my sig
 
According to that, it reaches just over 100 mW at 120 mA. I could probably buy an adjustable output driver to control the power. These will run considerably weaker than 200mW red diodes right?

As a beginner to the laser world, here is my parts list:

A) 1x PHR-803T Diode ($8 group buy)
B) 30-150mA Adjustable Output Rckstar Driver ($18)
C) Aixiz Housing Module ($6)
D) 9v Battery
E) UV Goggles
F) Soldering Iron, Solder

Anything else?
 
I think questions 1, 2 and 3 are all answered here in the forum sites.
A search and read should suffice to cover this.

Preferably some sort of host and heatsink combo. Jayrob has heatsinks for MXDL hosts off of dealextreme as well as custom ones. Likeitbright does custom heatsink work as well ($35 for saik rc-a2 + heatsink).

But with the rkcstr driver, you can buy the resistor kit and change the output range if you ever want to. There's an M$ excel file on his site to compute the mA. 30-150mA is fine for the 803T.

These will run considerably weaker than 200mW red diodes right?

As far as raw power, yes. But things usually burn easier with the short focal length. So it takes more mW for the red to match the mW of blurays, as far as burning goes.

And I know HighTechDealz has AixiZ modules for $4 shipped
 
Thank you for all the information treb! I will compare both AixiZ sellers to see which one comes out cheaper (w. shipping that is). All questions answered so far. Waiting for group buy seller to set up payment page.

I know I have to be safe, it's going to suck knowing that I'll never be able to look at the laser with my eyes alone. The goggles are gonna make everything different.
 
Anytime. Keep in mind the input voltage requirements for the drivers and host size, though. FlexDrive is required for single battery hosts-usually as the rkcstr needs >7.2v for blurays. Jayrob has some excellent tutorials on how to piece a host together, some with DDL or rkcstr and others with the flexdrive drivers.
 
Yeah I will use a 9V for the rckstar drivers. Is a host required? I'm doing this mostly for learning purposes and to keep myself busy over the next few weekends. A host is like a fancy casing, correct? The AixiZ alone looks quite nice to me.

But then again, I enjoy looking at bare electronics.
 
a heatsink is still recommended. some washers or something that fit over the aixiz module should work. but you'll need to a shorter duty cycle at higher powers. I think i've read about people on here drilling holes in computer heatsinks or something.. would be kinda neat for a lab style heatsink if you can get good surface contact with the fins somehow.
