Gonna agree with this.

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Hmm, I might need to get the 488nm too then:drool: I remember only a year or two ago people here were paying like $1000+ for a 488nm pointer from CNI.

For classy and safe <5mw pointers you really cannot go wrong with LaserGlow. I've never hesitated to recommend their Lyra series or give them as a gift.

This is one of those "cool in theory", "impractical and dangerous in real life" type ideas.

True lol :crackup:

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Just bought a 505nm guardian to add to my wavelength collection. Would there be any point in getting one of the 488nm guardians if I already have a 495nm guardian? I assume the colors would be almost...

It would be great if manufacturers would adopt a standardized battery scheme which is always followed. Basically the negative side of the battery should go towards the spring. Seems like most things follow this scheme, but every now and then you get some weird product which doesn't.

Oh, that's easy. 589 nm direct diode would be a dream come true. DPSS yellow lasers are super overpriced and hideously inefficient.

I always get annoyed by jokers like these guys who run a predatory site trying to take advantage of ignorant customers who don't know any better.

Welcome back, always good to see long term members still around.

Amazing builds like usual, I've come to expect nothing less from your threads. I've got a Sanwu 495nm, and it really is a unique laser color. Not quite green and not quite blue. It's sort of like how 561nm is between green and yellow.

Welcome to the forum. Plenty of helpful people here so long as you're willing to do the basic legwork to become familiar with things.

Looks impressive, would be nice to see somebody review one of them.

Sounds fun, I still need to post a review of the 495 nm laser I got from sanwu a while back. Maybe I'll finally get the time this weekend.

Sup, I was never really gone, I just got really busy with work and other projects and forgot to post here for a while.

Honestly I have no idea. I assume there must be some kind of life out there, even if only primitive pond scum or something. With that said, I won't be convinced that aliens have actually visited us without some kind of proof or first hand experience. I put that idea in the "I want to believe"...

Excellent and detailed review. +REP

Soldering irons are something you really don't want to cheap out on if you're serious about electrical work. Buy something decent like a Weller and it will give you a lifetime of outstanding service. Bad/cheap soldering irons make everything harder at best, and can destroy sensitive...

That laser can burn things, but I'd recommend spending a bit more for a Thor M2 from laserpointerstore or something.

If you have some magnetic battery spacers you can possibly use them to check for connection issues. Most issues are related to the batteries not being quite long enough. Also if you have a multimeter try checking the battery voltage just to be sure.
