The Coherent Compass lasers are adjustable output by a analog 0-5V input, So you can dial in whatever output you want. At which point they settle back into SLM operation after a minute or so. But the 215 has two thermo electric controllers in addition to the diode driver. Without driving the...

Sam has a very nice complete 215m that is tested SLM and does 16mW. He also usually has some Uniphase uGreen stuff lying around. Sam's Classified Page Or, I have a 315M-100 head tested by Sam. This one is low hours but has a intermittent second mode that is less than 2 percent of output. Of...

They look like five inch. Sam has some six inch tubes that look like these. He has several power supplies including AC and 6 or 12vdc. Less than $50 with shipping. Sam's Classified Page If you have never owned a HeNe, get one. --John

Those pointers can be had for the price of a Coke around here. He said it was 1mW and "after 1 minute the intensity decreased". The problem is that those lasers are a bare chip bonded to a little heat sink that does not radiate very well. You can get 5-8 mW, but they heat up in just a couple...

Jake 21 got me for $23 No big deal, I spend that on lunch. If thats what its worth to be a thief, fine. And he preys on new people, makes it look like dishonest intent. Maybe he is in over his head, and decides to stick the new guy first. And I'm new, so new I owned a laser before he was...

I cant seem to find that post either, but that wooden RGV was done by FireMyLaser. With a PWM RGB micro controller that cost 6 bucks. You can see it in his youtube video"RGV Laser Awesomeness" http://www.youtube.com/watch?v=XxfQktdH70c I have 3 of these RGB CONTROLLER CHIPS from...

Another reason for us to get what we can from you. If they have what I want in Alabama thats where I'd go. Or some of the other usual sellers in here. I'm still hopeful that the diode being tested will be a bright one. I wont be holding my breath based on some of the date codes. --John

Great !! Thats why I'm here. Theres quit a few "swell guys" in here. And I like the dedicated BR section, as opposed to PL. Though I also know some good people that stay over there at the other forum. And I never did like that flashlight forum much. Back on topic, lets hope that sled Amkdeath...

I gather. And I do recall seeing his avatar. Its just that I hang mostly in the 405nm section, and he hasnt been real active here in the last few months. And I've seen your avatar before too. And I'm only becoming familiar with you today. There's alot of people in here. Maybe I should give a...

I don't see anything thats really screams no, yet. It would be nice if Jack was a reliable supplier for all those various sleds. Really nice if that 8x comes thru... And Amkdeath is a member I'm not familiar with, but he has been rep+1 by some prominent members. I think I could trust what he...

Ok pseudolobster. Thats the weirdest thing I ever saw LOL. --John

Thats a JIN PENG website. And a JIN PENG email address. He posted 73 times in a week, and has not posted since. Now this is a different email address. A yahoo account. Maybe the same guy. Maybe not. And pseudolobster, please change your avatar. If I happen to look at it, I become mesmerized...

Or on the other hand..... This could be "THE" guy that all the sleds come from in the first place. It would be nice if somebody is familiar with the address. jinpenglaser@yahoo.com.cn I would be suspicious if he wanted to pass out only a few for testing, and was mostly interested in group buy...

At those prices, who cares about the middleman. I got the same email from JP. But I wont contact him. Demand drives up prices BUT this may be a scam Established in 2001, Jin Peng Electronic Trade Co.Ltd. is a diversified enterprise integrating wholesales, manufacture and import and export of...

Great build Chuck!!! I always wanted a real phaser. Looks like you did a pro job. And thanks for the tip on flashpaper, were always looking for something to burn. Flashpaper seems like a winner. I had to order some from http://www.magical-tricks.com/flashpaper.htm. I cant wait And welcome to...

You know that pinwheel effect seen in your "awesomeness" video was exactly what I had envisioned doing. But this RGB chip will make it easy. I was trying to think up something much more complicated. You saved me time, money, and a bunch of space on a circuit board. Thanks for showing that IC. I...

Congrats, the first finished build. I'm sure your having fun now that your really portable. Just don't forget how dangerous these things are. Have you ever seen a biplane with a aluminum cowl. Where they used a powered rotary hand tool to polish in overlapping swirls. You could do it with a...

You probably did not hurt the LM317 or the voltmeter. Might be a good way to hurt a laser diode though. And it would be quicker to build a dummy load yourself. I think Radio Shack sells a 50 pack of diodes for a few bucks. There should be about 10-12 1N4001's in there. And some 1N4002 diodes...

Uh, maybe, uh. If I understand correct, that wont work right if the diode is connected. Your parallel with the diode. Some current going through the diode, some though the meter. You have to flow all the current through the voltmeter to measure current. You can put the voltmeter between the...
