    Turning an X-Drive On/Off via MOSFET

    That's the route I would go. Although maybe that's over complicating things if you're not comfortable modifying your driver. The driver itself doesn't expose the EN/PWM pin, but I'm almost certain that the IC itself would have one. EDIT: In fact, that's exactly the route I did go with my...

    Turning an X-Drive On/Off via MOSFET

    I don't know...that's the point of what I was saying - it would require a little bit of logical deduction to find the PWM/EN pin since you don't know the IC, but it should be doable.

    Turning an X-Drive On/Off via MOSFET

    It strikes me that a much better approach would be to find the PWM/EN pin on the IC and control that, rather than killing overall driver power constantly. It should be relatively easy to identify, even if you don't know the IC, just by continuity testing with a DMM. chances are the pin is tied...

    Wicked Lasers Final 40

    Have they given you the tracking number. If not, assume they haven't shipped it. Nobody in China ships anything worth more than $10 or so without tracking these days. So if not, then dispute the charges with your CC, and move on.

    No longer WTB: C Mount 5W 650nm Laser Diode

    Re: WTB: C Mount 5W 650nm Laser Diode Edge Driver, version code F76V# is designed for low Vf sensitive diodes. I'll test it on a 4W IR C-Mount when I get a prototype board in (if I forget, and someone is reading this thread a month from now, feel free to remind me).

    Argh.... lots of typos. I should also note that the list of mappings is itself random.

    For Donation - Prototype 4.3A Buck, "34LIFV6V2"

    Here's how we keep it fair. Someone, anyone, even one of the contestants, will choose the winning number (between 1 and 45). Each number maps to one of the contestant's entries (danefex has 30, chaoslord has 10, nwfreefly has 5). The list of mappings has been posted here...

    Flying laser (quadcopter + burning laser)

    No kidding. I actually took mine apart fairly shortly after I made it, and put a big warning on the thread: http://laserpointerforums.com/f65/airborne-laser-hobby-edition-87922.html 3E10b_PgXdE https://www.youtube.com/watch?v=3E10b_PgXdE&hd=1 It's scary.

    I found it, Pyramidal Woo Woo Central

    I understand the value of emotion and imagination. I'm a big fan of science fiction. I'm a big fan of imaginative thought-provoking fantasy. The problem occurs when gurus start promoting "woo woo" ideas without the qualifier acknowledging that they are fantasy or science-fiction, and instead...

    I found it, Pyramidal Woo Woo Central

    If "woo woo" is a term that refers to (according to urban dictionary) "Unfounded or ludicrouse beliefs - Belief in talking to the dead, belief in telikenesis, in fact any belief not founded on good evidence, the poorer the evidence the more Woo Woo the belief." Then our society would look like...

    I found it, Pyramidal Woo Woo Central

    Ugh.... is "woo woo" an actual phrase? Laser Projector always posted crap labeled "woo woo" science, and I just assumed that was a phrase he made up. I also assumed it was over, but I see that the nonsense has infected others :(

    pic size limits

    Okay, what if your image is portrait? If it's limited to 600 high, then a 3:2 image is going to be max 400 pixels wide. That's pretty low resolution, even for luddites.

    Ehgemus fan thread, post your photo's of the host he built for you.

    Re: Want an unusual host built? Just ask Ehgemus - My RGB! How parallel are the beams? I'd be curious to know if he could do something similar with 7 diodes, closer together.

    Sold: G9 lens in holder

    I don't think it is. I could be wrong, but I don't think O-Like's lens is actually G2.
