    PWM or TTL controlled driver

    I want to build a PWM driver for my red and UV diodes. (6X blue ray and open can Red) Has anyone tried this approach? I am using an LM317 with pot to set the current then a 2N2222 to tie the adjust pin to ground when I want to turn it off. Any one have any thoughts on the best) and safest way to...

    Glow In The Dark stuff

    I am making a better GITD panel and just Ordered 1/2 pint of this http://glowinc.com/detail.aspx?ID=3 I remember Daguin recommending to Not get the Ultra Bright as the glow would not fade fast enough do achieve cool stuff. Anyway, what are other people using for cool GITD paint or anything...

    History of the 803T?

    Who first figured out that we could yank the diode and DIY it into our own creations? WHo was the first on the board to build one and figure out the pin out etc? I am fascinated how information like this gets disseminated gotta love the internet. I gotta thank the board for getting me back into...

    DX 35mw Labbie Green

    I just got mine, I am at work and can't power it up. Couple observations: The PSB shows AC input and those leads go straight to a bridge diode on the board. There also appears to be two complete sections. One for Red one for Green. Outputs to the Laser module show a green connector and a red...

    Sanyo Catalog of Diodes...

    I found this although I think it might be old news. There was a comparison of the current 8011 diode to the Sanyo in another thread. Here is what I want for Christmas... The "Under Development" one! Here is the link to the Catalog...

    803T drives left??

    Are there any remaining sources for these?  Hopefully in the inexpensive range? I "need" to run one @150ma and don't want to lose the one I have... I missed the $17 sale locally for the X-Box 360 HD-DVD drive. Waa! Jules

    My 2 motor spirograph project

    Just finished a spirograph this weekend. It has reversible motors http://www.youtube.com/watch?v=5TDTlyhr3HU I am using two small DC motors and found a sweet way to drive them. I am using a 10K pot with the wiper tied to the base of small transistor 2N3904, used as an emitter follower. It is...

    Got her Going! 803T

    Here is a pic of my Sony 16X DVD Red running at 150ma, the 803T up and running @ 80ma and the DX 30mw Green. I tried a highlighter but it was really old. THen I tried blueing for clothes it didn't fluoresce but did show the beams. Then I painted with it on some GITD stars and plastic thingies...

    Glass vs. Acrylic lens?

    I just got a glass lens for my Aixiz module and am wondering if I should use it for the Red laser or the 803 UV laser? Thanks in advance!!!! Jules

    803T Max and nominal current?

    What is the max and nominal current that you run to the 803T? I have burnt one (although I am not sure it was due to over current lol) Before I fire up my next one I want to be sure I am in the "safe zone" I am looking at just the Aixiz module as the only heatsink to be conservative Any one...

    Digital and Video Camera Safety...

    I have noticed on a lot of the pictures people post of their beam shots that the camera CCD appears to have some damage. Usually the multiple beam shot pics have the same spots or glitches in the same place. Any one have any suggestions on keeping your camera safe? I am about to finish a 803...

    Hello from Jules in Texas

    Hello all I am very excited to have found this board. In a nut shell I am an avid hobbyist. I build my own speakers and other assorted audio gear, mostly in the studio kind of thing. I am an electrronics guy with a degree in Physics. I LOVE Lasers and played with them all the time in college...
