    Super glue damage from the battery terminal side of the driver. - Album on Imgur Lifetime17, your lasers look amazing. Why are the Heatsinks so far protruded? I love the look, but purpose? Higher duty cycle? How large of a diode could you possibly have in there? Im an engineer but fairly knew...

    Need someone to replace / help replace a driver

    http://imgur.com/a/tKZZJ What is the correct terminology? Are the two silicone circuit boards inside the heat sink housing both part of 'the driver'? Usually there is just 1 but this is more complex because of the pulse / low / medium / high features. What does it cost for a driver that will...

    Need someone to replace / help replace a driver

    Hello, The driver used in this laser I purchased (http://laserpointerforums.com/f39/sold-4w-ndb7a75-mx900-host-250-shipped-95836.html) has been ruined. The spring on the opposite side of it that touches the batteries fell off and I used super glue to put it back on. I found out quickly this...

    sci fi laser still in business?

    I have spoken with Mr. Joker within the past few days. I have one of his sf501b 445nm 2.4W. Theyre amazing. Hes the main sponsor here and i'm sure hes very busy. One of my lasers was damaged in the mail and it took ages to send back (not his fault) but quite a bit of time to get around to...

    1-1.2 watt 445nm lasers

    Re: 1-1.2 watt 445nm lasers CHEAP $180 As i was cleaning my lens i noticed as i rotated the lens the smuged area wasn't rotating with it, after taking the lense off i concluded that the diode might have a smudge on it. Is that an ok thing to clean with some rubbing alcohol and a q tip?

    Yobresal Build Possibly Underpowered

    @jbtm How focused are you making it? Pinpoint? Doesnt that just burn right through it and form a tiny hole? Or are you holding it so its a little past the focal point and ur heating up a larger area and it finally burns? Do you get it to burn through and then start heating the outside of the...

And im trying to focus a little past the focal point so that it heats up more area and maybe after a few sec it...

    1-1.2 watt 445nm lasers

    Re: 1-1.2 watt 445nm lasers CHEAP $180 This laser owns. Bottom line. If you want a cheap yet amazing laser. This is it. Though the lense does have a bit of a wobble. But apparently this can be fixed with a bit of Teflon tape or a spring. Question though, can i charge these 3.6v cr123 with the...

    Traveling at the speed of light...

    @pullbangdead I'm not sure how you are interpreting what im saying, its very simple. You add the velocities just like general relativity tells you, and you multiply by '1/1 + uv/c2' depending on whether the objects are moving towards or away from eachother. This basically is using the time...
