I tried posting them, but I couldn't figure out how. :P However, you can e-mail me to get them if you want. Send me a message for the address. Sorry for the inconvenience... :(

Hey guys! I finished my first laser last night! It's running at 125.9 mA, and I can't measure the output, but it can smoke electrical tape. This has been a wonderful first project, and I can't wait to build more! Thanks for all your help and I'll see you around!

Hi! I'm new here and have much to learn about lasers and the laser community. I'd love to get to know you guys and get some words of wisdom. See you around!

Yeah, I have been pretty spaztastic. I was hyper and didn't know what I was doing (I'm better now). You also brought up some interesting points, and I'll be sure to be more careful with my words. Thanks for your time, and I'll see you around.

I know I keep changing my mind about what the heck I want to do, so sorry. :P (so. much. n00b.) I have a question, is the 100 ohm pot necessary? Or would just one 10 ohm resistor work fine for a PHR-805T?

I don't know, I'm just using what I have. Perhaps someone can explain what's so special about these other batteries?

AAs can deliver more mAh than 9V batteries. I'm willing to use more space if it means more current.

Honestly, I can't remember a lot of those details. Also, the PHR-805T diode is broken. I want to start over, but with a completely different diode. I'm a little ambitious, so I want to build a blue laser that produces about 200-500mW. I still want to try to use the LM317T, but with a variable...

In the build I tried, I measured the current by inserting my Fluke multimeter in the circuit and used the 300mA setting. The current was 37-47mA. The voltage coming out of the 8 AAs was about 12.5V. The voltage going across the 10 ohm resistor was .35V. Is it possible the PHR-805T was a little...

Vout is the middle pin, right? I also think the AAs were in series.

Hi everyone! After having some odd problems with my PHR-805T laser diode and Styropyro's 3$ laser driver build, I thought I would ask for some help (I need it badly DX). I began by using 8 AAs, using the positive wire to go to a switch. I then attached a positive to the other side of the switch...

Hi everyone! I'm back, as puzzled as ever. I attached the + lead of a 9V clip to a switch, then another + to the 'in' on an LM317T. On the 'out', I attached a 10 ohm resistor. On the 'adjust', I attached a + going to the resistor. From the resistor/+ combo, I attached another + that led to a...

One last question... What's the highest current I can give the phr-805t?

Would an aixiz ar coated lens focus the beam adequately?

Thank you very much! Just one more question: should this produce a fairly powerful beam? I'd love to burn stuff with it. Oh, I also forgot to mention I'm powering it with a 9-v battery.

Hello everyone! I'm new to LPF, and have a question for you. I designed a laser, called LPRD, and I'm using Styropyro's $3 driver design to control the current going to a PHR-805T laser diode. I tried to find the numbers for resistance, voltage, and current, but I'm having trouble doing so. That...
