That type of driver will require 8-9V of battery power to operate.. ;)

I have been buying from Digikey for many years now. My only complaint is they don't give me the actual shipping charges until AFTER I place the order, and even then I have to look it up at the bank to figure it out or wait until the package arrives with the receipt - they are the only one I deal...

Re: 215mW 6X Key Chain Blu-ray! - With FlexDrive! Hey Igor, Let's say you do put a mini USB connector in there. Then take a USB cable and cut it in half and insert a charger PCB out of a DX "DSD" charger in line and put a big piece of HS tubing or something over it. Bingo - you can now...

For those of you still insisting on using linear regulators, why not replace the old-fashioned LM317 with this low-dropout regulator and save on batteries? http://www.national.com/ds/LM/LM2941.pdf ;)

What's next, nano-bots with fricking nano-lasers mounted on their heads!? ;D http://machineslikeus.com/news/miniature-laser-breakthrough

Re: 6x feeler!!!55.00 shipped Put me on your list for 2, please :)

185mW out of a PHR! :o You sir, are a fiend. A LUCKY fiend! ;) Nice night photo, I'm jealous cause my Cannon A540 is blind to 405nM. :(

Last I heard they sell in lots of a hundred, unless you get lucky and they have a smaller Qty - like 50 or so. They would have to prove better than the 6X to make it worth while. ;)

Re: Laserman532 Blu Ray  A NEW Standard of Ex Don't forget to add some aluminum foil for heat sinking.. ;D ;D

I'll take as many as I can without having to sign any divorce papers! ;D ;D ;D ;D ;D

Re: 215mW 6X Key Chain Blu-ray! - With FlexDrive! Igor, for whatever it's worth, I think you are on the right track with the prismatic cells. As the batteries get smaller, the internal resistance increases proportionally. For a 10440 it is around .35 ohms at full charge and about 3 times that...

Re: PLUG & PLAY CO2 BURNING LASERS only $150 DELIV What kind of power output can we expect from these - my meter won't go this high? :o Just wondering if they are in the 8-15W range...

Re: Key Chain Blu-ray... With FlexDrive! This battery was from DX, but I have tested these before and already knew the capacity was really just over 300mAH, and was real happy to see that the specs for the AW batteries match my tests! Actually most of DX's Li-Ions have ridiculous ratings...

That focus label is a nice touch. Thanks for posting the file :D On the Safety labels, some classes appear wrong, though, they should follow the chart below- Old style classification New Power II/IIa 2 <1mW IIIa 3R <5mW IIIb...

Nice Work! These Li-Ion batteries open up a lot of possibilities... :D

Those are kind of cute, but... there would be some problems :-? Neither one is CURRENT regulated, which would require additional circuitry. The first one is too big for most hosts, I would think, but has enough output to power a Bluray. The second one, falls short of the needed 5.5V for...

Re: PLUG & PLAY CO2 BURNING LASERS only $150 DELIV I would like to buy one of the remaining PnP units, could you PM me payment details please.. Thanks

Re: Adjust your laser's output on the fly(digital Exactly! A dual comparator, dual op-amp, or 555, and you get 0-100%, virtually infinite resolution, no assembly (language) required - I have one in my shed that dims 12V light bulbs, and that is what I used for the driver (LM393), because I...

Re: Key Chain Blu-ray... With FlexDrive! Sorry, i was missing for a couple of days... Well I did the Constant current discharge for the 10440 - a brand new one, fully charged to 4.2V. I needed to learn to use a better graphing program, so this is a sort of learning experience - now my...

Re: Key Chain Blu-ray... With FlexDrive! Alright Igor, we can all understand torturing diodes, but Batteries? Dear lord, where will it all end?! ;D (I was back a few pages) Would anyone be interested in my doing a Constant Current Discharge curve of a 10440 or other Dia. Lithium cell? I was...
