    Sanwu RGB review

    Interesting how the intensity of the most head on beams changed their color (increased their saturation I guess). I almost thought you had 3 other lasers lined up behind the diffractor , NOT shining through it, like 405 and 505 and 445.

    How to make your way overspec $5 pen focusable + new bonus section added

    I actually found last night that weak green was just an unstable one. I tried using it for longer than a quick flash and saw it flicker bright and dim for 15 seconds until it became a solid medium power. I found that if shut off for a second, then first 1/20th of a second was as bright if not...

    How to make your way overspec $5 pen focusable + new bonus section added

    I am curious to know why the power seems to vary so much with these pens. I didn't see a pot on the regulator in Pman's first post towards the bottom, so it probably isn't from slight differences in how it was adjusted. Maybe the design of the regulator is so bad that each one has a different...

    Macro pics of <5mW Laser Diode

    It is complete with a switch, battery spring, and resistor for limiting current. So I'll just give it 3x 1.5v batteries like what it took, but I'll use batteries bigger than buttons, but not bigger than AAA

    Macro pics of <5mW Laser Diode

    I was powering it with a little more than just enough to light it @ 2.1v, hardly enough to form any noticeable unidirectional emission. A little more power, and a huge contrast forms between light going in many directions and the main beam. this one was supposed to run on 4.5v of button...

    Macro pics of <5mW Laser Diode

    Sony wx220 looking through either a 50mm 1.7 lens or a 24mm 2.8 which isn't as good (too much magnification which causes distortion)

    Macro pics of <5mW Laser Diode

    I found this module out of a dog laser that had been lost and trampled in someone's yard a year ago. The diode must be less than .1mm, maybe even around .05mm or less wide. Super tiny

    Techhood are incompetent imbeciles, I cannot do business with.

    What's the hurry? DHL tends to be 3 days from china with the best case standard speed scenario being 1 day due to time zone change, and fast processing. They oughtta give free shipping when they fix the mistake.

    Need a laser that can burn iPhone camera sensor

    I'd think the desired effect on the picture would get old fast. Better to get an old cheapo camera off craigslist to do it with. CCD sensor might be interesting. But certainly any 8 year old these days could write a picture editing app with damaged sensor effects.

    What color is it? I'd complain to the seller, probably a mixed up order.

    How Much Laser Power Gets Through Goggles

    I'll be more careful in the future, but I was trying to point out that the lenses were green by just calling them green goggles when asked if they were full spectrum goggles, which they are not. I just said "green goggles" not "green laser goggles", but I see how it could be confusing.

    Enchanted Beams Thread

    10-30 second open shutter with one laser turned on at different times. Varying the duration makes it look like different laser powers. I was testing, trying to set the laser back to infinity after burning with it.

    Not much of a camera, but I hope these are good enough
