    Not Again!

    Man sorry to hear that, I don't know what is up. Mine is still strong after several 20+ minute runs.

    Miniumum voltage needed to shock?

    Unlucky one here, caught one side of 480 main (220) here while back at work, it was locked out but the idiots who worked at the plant took the lockout off and turned back on the breaker while I was working on the line. They needed a pump on now, now they need a job. That was an experience I will...

    RadioShack Green Laser

    I don't know if it does have a filter or not because when mine gets real cold it doesn't lase green, but when I look at it with my cell camera I see a butt load of IR light, almost like a white led inside the hole. Wouldn't an IR filter block that?

    Voltage of open can long die?

    Yes, up to 35 volts, the laser only will get the 3 volts it needs to run and the LM317T dissipates the rest as heat. Note at those levels the heat sinking.

    Laser LED Guide on Kipkay Video

    Finding that specific one will be hard as it is a cheap mass produced one. There are soooo many types. I will look at flea markets around here for anything similar, and if I find one I will get it for you as they only cost around $1. It might not have the blue LED though but I will make sure it...

    Glass collimating lenses?

    Also try Teflon pipe thread tape, works wonders to tighten up the threads.

    see red at night?

    Yeah even a 300mw red is nowhere near as "bright" as my 5mw green in open sky (no fog, clouds), but it is visible at 100 yards. (laser straight up at one end of football field, pal at the other)

    Voltage of open can long die?

    You can go to 420ma and be ok on a long open can. The voltage stays the same at the laser, its only current that changes. Really the DDL driver needs at least 7 volts to run efficiently, if I'm not mistaken, but could run on 12 volts, with serious heat sinking on the 317. Add another AA to it if...

    Laser LED Guide on Kipkay Video

    Walmart has a decent one for $20, if you need it now and a wally is near. Has a pressure switch and other stuff with it. Think It's a BSA. Also a Daisy one in the pellet guns and a crossman, and an airsoft pistol with laser for $20, but its probably a chip diode.

    RadioShack Green Laser

    I have a butt load of IR filters out of cameras, those ok to use as a filter, or different IR wavelength use. I love having a friend who owns a camera shop, cause I get all the busted digital cams I want and loads of different optic pieces out of the lenses to play with. Oh I am gonna keep this...

    RadioShack Green Laser

    I bought one Monday and like it alot, but wish I was patient enough to wait for shipping on the 50mw from ledshoppe. After seeing the 5mw beam the 50mw must be awesome. Are they worth it to ship to USA. Thinking of taking it back now but my little girls love it, and I think 50mw is too much for...

    Indestructable 22x ?!?!

    They're not indestructible, don't sneeze while soldering. It rips pins out. :-[ Other than that they rock.

    possible 3$ boost circuit

    Agreed, but what about driving a flexdrive, or is there still not enough mAs? Seems not likely because as far as I understand there has to be the required mAs for the flexdrive, but I still don't know what that is. (800ma 200ma 100ma) Get what I am asking?

    possible 3$ boost circuit

    Thats nothing, the ones I killed went up to 142ma and as low as 51ma. No modifications done yet though. I have been through 7 and have 3 more

    possible 3$ boost circuit

    With the test load on mine I got 3.1 volts @98ma. I have been messing with one of these for a month now, trying to get it to work alone, but figure it might work with a Flexdrive.? With the original LED in place it reads 3.41v 78ma.

    My first blue ray pointer was great... from FRANCE

    Re: My first blue ray pointer was great... from FR Did this module come in the laser or did you buy it? Thank you and sorry about your blue.
