Hello again everyone. It seems my recent post is one of the victims from the server upgrade, so here it is again. If you replied previously, I did not see it. I'm looking for a source of motors to use for a spirograph. Preferably 12v as everyting will be running from a battery, and so far I...

I'm looking for 12V because the laser power supply runs on 12V, and the whole system will be run from a 12V car/marine battery. I could add a stepdown transformer, or maybe a regulator, but that's wasted energy, added heat, and more work! :p

I have optics for liquid sky. Looks great with 445nm! Awesome, thanks! Yep! You're welcome, heh. :)

Hello everyone. I'm looking for 3-4 front-surface mirrors, about 1" to 1.25" would be most ideal. Does anyone have any for sale, or want to point me to a website that has reasonable (cheap) prices? Also, while you're reading this, do you have any recommendations on bidirectional 12v DC...

My Arctic arrived with a single-cell charger, and a sea-green Samsung battery. I read the battery thread, and someone mentioned Samsung as a high quality brand. ICR18650-22F SAMSUNG SDI 1A35

I'm on the West Coast of California, so for those of you who were promised you'd receive your Arctic by Christmas, and live on the West Coast (where customs notoriously confiscates ALL Wicked products), they have found a way to make good on their promise (a first!). I have one of the very first...

I don't know anything about the driver or diode they use, but given the heat sink isn't anywhere near what a DIY would have, I wouldn't even attempt it. Even with a nice heat sink, I killed a 300mW red in less than a minute. Overspec is just a marketing procedure due to human psychology...

I'm not a spammer (thanks for the vote of confidence), and have nothing to gain from sharing information here. Rest assured however, if I were selling one of these lasers, I'd post pictures (and/or crappy video) to backup my claims in order to help the sale. For now though, I'm keeping them...

Pictures? Seriously? Would you like the picture of the initial peak, or after it's settled down? How would you trust that I posted the picture I said I did? Oh, then someone would want video. Then I'd be accused of taking the best one of a bunch of each. Then... You see, what I've come to...

I ordered a batch of O-Like Red/IR "New Style" lasers, and tested them on the LPM. All are slightly overspec - here are the test results: 980nm/150mW = 155mW 808nm/220mW = 230mW 780nm/120mW = 130mW 780nm/120mW = 125mW 660nm/200mW = 205mW As for the recent discussion of "Old Style" vs "New...

Just checking in on the community opinion of ThinkLasers. I searched the forum and found problems earlier this year, but nothing lately. Are they actually located in the US? So, if they ship an "in stock" laser, it's already been through US customs? Since they resell Wicked products, would...

What's the best place to setup a permanent DMM to measure current on a setup with external variable current pot (so that mv readings can equate to know/measured power)? Inbetween diode and driver? Inbetween driver and battery? Thanks!

SPACE.com -- Snapshot: NASA Fires Twin Lasers at the Moon

Seems the Spartan has hijacked the Arctic thread... On that note, is it reasonable to assume the 400mW Spartan is running the same power as its big brother, only the losses from the beam correction optics are reducing the power to 400mW? Still waiting on my Arctic... 47xxx... *sigh* EDIT: Been...

They both probably sourced it from the same laser manufacturer. I doubt either company actually makes these...
