It was completely overcast where I live, maybe one day I'll live north enough to see them. Love the pics!

Videos and pictures lie. Even if you are in the same place at the same time of day you cant control the atmospherics and how your camera will respond to it. Take for example: The camera would suggest the green is brighter despite the blue cranking out 56 times the power! Thats 125mW vs 7.1W...

Did you measure the green to actually be 700mW? I have a 524nm @ 750mW that absolute smokes any of my 425nm-450nm blues that sit in the 1-2W range. Once the blues start getting up around 460-470nm they get pretty close thanks to the extra power. Are you comparing brightness between the lasers...

Alien, have you had all of these just squirreled aways for a decade or something?

We need more hosts like that, it amazing!

These are sweet, I love drivers capable of running off of a single cell.

A buffing wheel on a bench grinder will be easier on your hands since you can use both to hold the host. Other than that it looks like you did manage to make a nice shiny spot already.

All the yellow and orange laser pointers are DPSS

I've let the smoke of out many laser driver with accidental reverse polarity, did just that today in fact. Some are protected but definitely not all.

Unfortunately there is no standard. Back in simplier times it was quite easy, red diodes are always case negative so unless someone goes through the trouble of isolating the module, all home made red lasers and store bought red lasers were case negative. Green lasers were also all dpss...

Now I'm almost sad I don't know what this post originally said

I think its because USB recharging allows for distributors to sell to a larger market, often times people who are new to lasers. If you present a laser that can recharge via a usb cable that most people already own, its more likely to sell than trying to market a laser that runs on separate...

https://www.ebay.com/itm/134043171833 Green NECSEL's! More of a novelty now that high powered green diodes are so common place now

He came, he posted, he left lol. Would anyone happen to have contact info on Smeerworst? His post says "more classic models available" so if he does intend on letting some of his collection go I would love to purchase some.

Haha, yeah I had one of those

Shes got some crazy curves! very cool looking

The host is very unique, is there a rationale behind the necked down section in the middle?

They both appear to be unprotected button top batteries, trading current caring capability for overall capacity -> 3A @ 1250mAh versus 10A @ 1000mAh.

DPSS 607nm would be tremendous, if you managed a small production run I would be in for one
