A bit late to the party, but I use Nitecore i2 charger. Pretty decent for the price (equivalent to $11).
It can automatically detect the type & capacity of the battery and then use the correct charging settings. (There is a way to manually change the settings but I never need to do that)
Ah yes, doing things just because I can...
Regardless of legality, things that attract public scrutiny wouldn't be good. Regardless of what happens to you, it has the potential to affect everyone else.
It's not hard to see why everyone treats you not so warmly. Asking the same/similar question...
Glad to help! The 1.6 watt 525nm is a new diode and it's not decanned, so if you really want 525nm it may be the better option to go to. (I imagine it'll be insanely bright!)
I spent quite some time contemplating before purchasing, so here we go.
Sanwu's "white copper" I assume means cupronickel alloy. It should be a similar material to the Nickel (5c coin).
When new, copper nickel and stainless steel look very similar. Stainless steel wouldn't discolor much over...
There are a few members who got Lasence modules. I've got one myself and the purchasing experience had been good.
Do note that alibaba is a marketplace like eBay though -- there are both good sellers and bad sellers. I vouch that Lasence is good.
Oh, and did I mention that they are developing...
Please, seriously read some basic laser safety information.
"Violet laser is better", better in doing what?
Any laser with equal power rating are equally harmful. The dim violet blurry dot of a 1W 405nm laser packs as much energy as the dot of a blindingly bright 1W 520nm laser.
Green lasers other than 532nm are usually direct diode lasers -- they don't emit IR at all.
As other members have mentioned: Sanwu Laser, JetLasers, laserlands (ebay)
I think that's due to technical practicality and philosophical considerations.
Back in the 70's, they were using conventional films, and IIRC the way they did lightsabers was to use some sticks during filming then sort of overlay the special effects manually to the physical film later...
