    Adjust your laser's output on the fly(digital pot)

    Re: Adjust your laser's output on the fly(digital I've used an existing pwm control circuit to modulate a driver, and it worked very well. The control circuit was a chip from a Photon Micro-light. The signal from that was fed to the shutdown pin on a buck/boost regulator. btw, You don't need...

    is my new BLU-RAY DEAD ????

    Here are a couple of ideas - it may take me a while to ype it all so I'm going to post, then edit this postas I get more written - I hope that works ok for you. First: any testing of the connections that you do should first be done without power to the circuit. Because if there is a loose...

    268mW 6X Key Chain Blu-ray! (With FlexDrive!) - Awesome!

    Re: Key Chain Blu-ray... With FlexDrive! waaaay off-topic here! but I'm sure the others won't mind, this is so much more interesting than little round batteries ;-) Remember my post about those really nice sky-blue LED's that light up with only 100uA? Combine that with the mini-LiPo; stack up...

    Laser Malfunction.

    <sigh> not at all - the diode has been fairly well-characterized, including the fact that they are somewhat variable. Some appropriate thread-reading would help your understanding of the subject... ;-) DanQ

    Laser Malfunction.

    Unfortunately, this may not be among those. Read Electrofreak's post. Read through The XBOX 360 HD-DVD high power laser thread ...or just about anywhere that IgorT writes about 405nm diodes. Through many, many blu-ray diode tests he has found that there are factors that will kill the diode...

    268mW 6X Key Chain Blu-ray! (With FlexDrive!) - Awesome!

    Re: Key Chain Blu-ray... With FlexDrive! Hey! that's not fair, putting the information up front like that - people aren't going to have to read all 7 pages to find the best way to go! ;) thanks Jay! but I do wish we'd get notification when someone edits a post like that... heck, I'd be happy...

    268mW 6X Key Chain Blu-ray! (With FlexDrive!) - Awesome!

    Re: Key Chain Blu-ray... With FlexDrive! :-/ I'm confused - what host does the 10280 fit (when tailcap drilled)?? and where did you get 10280's? I'm trying to follow this discussion, with notification being sporadic at best (and my attention spaan not much better)

    268mW 6X Key Chain Blu-ray! (With FlexDrive!) - Awesome!

    Re: Key Chain Blu-ray... With FlexDrive! Powerstream there are a number of sizes of these ultra-lights; a lot of possibilities, but probably won't be too useful for lasers. But that little 10mAh unit will power an efficient led for a loooong time! I had one hooked up to a little blue LED that...

    Strange Things About Blu-Ray (405nm)

    Right - I've been advocating a bleeder resistor across that 'protection cap' for quite a while, but it doesn't seem to catch on... everyone mentions the need for a cap but not the R. It's such a simple addition, and if you use surface-mount components they take up very little space - could even...

    Laser Malfunction.

    In my experience - which admittedly is not as much as others here - a current of 100mA is just about right for the average PHR.  Since the PHR's vary so much it's hard to say how much power you'll get out of it, but there's a graph around here somewhere that shows a current/power curve. If I can...

    That reminds me of something I've been thinking of lately. It would be good to know how old people are - or at least whether they are 18 or 21. Why? so we aren't selling to (or being sold to by) minors. I'm a bit nervous about the prospect of some kid getting a laser here, then doing something...

    ditto. AMK, you just reiterated the very reason for true Group Buys! that is, the ability to pool our resources to do what we would be unable to do as individuals. BUT - as soon as somebody shows up (hopefully in For Sale section) who can does front that money and time themselves - AND sells...

    In need of Soldering / Diode Help

    Re:  In need of Soldering / Diode Help Kyle, a really good way to practice soldering - and test your soldering equipment - is to get some old electronic item, like an answering machine or older CD drive or whatever; and take it apart piece by piece. Some of that will be mechanical, like screws...

    most of us would welcome that! anyone wanting to pay me for no reason, PM me and we'll figure out the randomness aspect once the PayPal transaction clears ;-)

    268mW 6X Key Chain Blu-ray! (With FlexDrive!) - Awesome!

    Re: Key Chain Blu-ray... With FlexDrive! I emailed to him a couple days ago; he said it'll be about 2 weeks until he has more. BTW - I think that other source  given on page 1 of this thread is the same guy no wait, AW is in China and Lighthound is in Texas, so he's their supplier - note the...

    Cheap Lead Light Host $9 Chrome.

    aaahhh... so you are the interloper! ;-) Cool, I'm glad everyone is ok with this. I don't mean to poke my nose into other peoples' business unnecessarily... sometimes I'm just grumpy :P time for my meds!

    Cheap Lead Light Host $9 Chrome.

    I don't know how current either list is, I just saw the obvious discrepancy in that statement so pointed it out. Did Jake drop out? he's on this list... were other people who show on Jake's, formerly on this list? I just don't know. DanQ
