Sigh. No where near as cool. But I recognize that stance. I have tried to crop mine to mask out the floor at the workstation. Cords, plugs, manuals, notebooks, whiteboards, pens, two area rugs, power buses, empty equipment containers, computer speakers, and my feet. Heh... eventually, I...

That's a good point. I didn't think about it until just now - with a different barrel to accommodate the "button", and a "locking" tail cap, it is potentially a "protected" LP. With the exception of the switches, the boards in both of the LPs are extremely close copies to the board you...

You are correct. I was going from memory and over simplifying. What they have done is include an aperture (a large pinhole) to physically remove some of the splatter/artifacts. I pulled the vanadate assembly from one the LP with the lower current and non-centered sticker (pinhole). I may...

I unscrewed the laser diode assembly to look at it again. Something I didn't expect to see - both of the laser pointers have a momentary contact switch mounted on the diode power supply board. I assume they bridged the switch contacts because the LPs are "on" whenever the circuit is complete -...

I haven't gotten any further than unscrewing the outer lense assembly from my 200mW FastTech (18650) laser pointers - mainly just to see what the laser assembly looks like. I did a blind "back of hand" test with the laser pointer, with and without the final assembly... I an say that I didn't...

Quick end-cap test: The laser pointers are billet as 200mW End-case amperage and battery voltage measurements from each: Black one: 420mA, 4.20v ~= 1.76W consumption Silver one: 320mA, 4.14v ~= 1.32W consumption I know this doesn't mean anything until I get a power-out reading, I'm just...

I *JUST* got my two green LPs (FastTech SKUs 3801200 and 3802013) today - about 2 hours ago. I thought it would take a lot longer. I will take some pictures and take what measurements I can, before I start any alien autopsy. My initial impression is - there is not much IR filtering going on...

Thank you. Well, now I'm getting TWO and I blame it on PayPal then. I moved the 200mW green laser off of my order and completed a bunch of flashlight, flashlight parts, and hobbyist electronics, and then to get the "free for $20 and up" tracking (or whatever), I ordered one 532 in a black host...

Anybody use FastTech for Laser devices? It won't let me use Paypal because I ordered a 200mW green laser. Are they secure for regular credit cards?

Ah, I meant to add that I'm looking at a 200mW green laser from fast tech - mainly for simple reasons: cheap (11 dollars), popular battery (I have dozens of spare 18650's), and at that price, if I totally screw things up, I haven't really lost much and I still have a cheap host. Pull off the...

So I'm reading about G1 & G2 lenses - but that's going in the opposite direction that I need to go. :D I NEED divergence. But it's neat reading about it. I am thinking that to really get an infinity focus would take two people... one @ the laser and one at the side of a target 30 or 40 ft out...

Thanks! Off to read up on OD and safety glasses. O-Like has a pair for about $20 less, but I don't know about shipping, etc. Maybe I can get all this figured out by the weekend and get an order together.

Thank you for reminding me. It's time I get some real ones. The glasses I got with a small 850nm laser are a joke and don't affect the beam at all. As an side, I've seen a couple articles recently about using 780nm and 808nm lasers at low fluence and through the eyelid for treating...

I appreciate the feedback. I didn't think about the fact that I'm not going to be TRYING to burn anything - focusing the beam and holding on spot with the intent of making it hot. I'm hoping to use it for photobiomodulation (LLLT). This normally involves illuminating a point for anywhere from...

Dang... only 1 post in 5 years? I thought I had done more than just lurk since 2011, but I guess not.

This is interesting to me. I want to find an 808nm illumination source - not for burning things, but for targetted transdermal irradiation. I had been wondering if hacking a green laser pointer would be an inexpensive source, and had planned some FastTech purchases of 5mW, 100mW and 200mW...

InfraRouge, Part 2- I've been looking for CHEAP, 18650-powered laser pointers. Real IR ones are pretty much out of my price range. I was going to go w/ the "Violet" 404nm pointers, and depend on poor filters, or try to remove the IR filter, and use them for focused therapy devices. Some...

Hey IR, Did you ever do the IR LLLT on your knee? I'm sorry you got such a crappy response from the regulars. How did it turn out? What was your protocol? Did you use manual controls (i.e., "thumb-gating") or electronic (TTL to control power through PWM)? I have been research LLLT and...

Hey Guy, I'm a new forum member. I've been haunting the forums off and on for a couple months, looking for some specific info about LLLT and 100mW 660nm lasers. I just noticed that you're on-line and figured I'd ask you direct... I saw a mention you made about uploading some pictures of the...
