fiber launching, your divergence probably depend the most on the size of the fiber relative to the size of the collimating lens. Generally speaking, and assuming well-made lenses, the larger the lens, the lower the divergence. But benefit is that if your fiber can handle the power, you can...

Like a soda-laden child in a candy toystore! That must have been fun :beer:

It analizes it :eg:

Review of Charger LiitoKala Lii-260 < maybe relevant info. I'm curious if these are the same. I'm glad analyzing chargers have come down in price. Used to be you could buy a battery analyzer for half a grand. Wouldn't even charge or do anything else besides analyze discharge.

It might be that the driver is powering the laser diode just fine, but perhaps the optics in the brass housing are not converting the output of the laser diode into green. Can you detect any IR using a cheap webcam or camera phone? Don't point laser at the phone. Shine it at a paper and look...

10440 is probably not the best choice for this application. LiPo often has higher safe discharge rate compared to similar sized LiCo. typical 10440 has a capacity of ~300mAh. I wouldn't take these past 1A discharge. I don't dabble with LiPo too often, but there should be specs regarding t

Nope, no damage. You're right, just an output cap discharging.

Sounds like political bickering to me...Russian Air Force playing the martyr, make America feel bad for escorting a large Russian aircraft flying offshore of the US. "See? We were only doing sciences for the good of all, not any practice bombing run" Really, I don't care who practices what...

Yep, it'll say that for a while until it gets to and through customs and into USPS's hands. For RC#####MY, use track17.net or track a package from malaysia's site, using the "FlexiPack" option in the dropdown box ALL-IN-ONE PACKAGE TRACKING or Track & Trace 17track is the shadiest url ever...

For those of you whose tracking shows that it's been sent to Jersey City, it is very likely that this means your item has been scanned on its way into a cargo container that will be loaded on a boat and sent to Jersey City. Once it is offboarded, unloaded, and scanned in, I reckon that is when...

hah, those guys always had teh best jokes. Even now, after they're dead!

There isn't a definite line between biggotry and stereotyping. But you can't satisfy 100% of the people 100% of the time. Me, I don't judge a book by its cover unless the author chose to put the synopsis on the cover.

Sounds like they miniaturized the classical beam dump using material that already has decent absorption, and I'm guessing tuned length to provide attenuation of UV and IR as well. I still think someday nanotubes will be implicated in some sort of horrible disease epidemic. But I'm just jealous.

I'm with Ped. Real FPSers use a mouse and keyboard ;) And if you go on XBox Live (or anywhere, for that matter) looking for racism, you'll find it. IMO, if you let your kid play on XBox Live, you may as well let them join a gang, sell crack, or do whatever it is kids do when you leave 'em...

If you are careful, just be more conservative with your current. If you cut it in half, you are even less likely to suffer COD from light being reflected back into diode.

These lamps are for streetlamp post #2,390 on I-40 Westbound. They don't fit any other streetlights. :eg: Maybe it is for a source of a particular wavelength? First electronic camera flash evar?

World's longest lasting keychain indicator light, this has the makings of!

Usually switch-mode drivers will start to flicker when the power source can't supply enough power. Still, I would recommend finding a better battery. Some cells have protection circuits that actually allow them to discharge at their rated maximum discharge current, but some don't...

Next project: solar water heater! I like that picture where you can't really see your house, but you can see that it is down the street because everything in the street is lit up by it. Be careful, though, some unsavory individuals might see that as a sign of wealth. At least, that's what...
