I think you can contact SpaceLas to see how much they'll charge you for a set of galvos. They ship from China, so you'll be paying for shipping, but usually their prices are pretty reasonable for some usable galvos.

Oldie but goodie WTF

Kudos to your friend for being so cautious and aware of the potential consequences of misusing lasers! After seeing a laser that produces a visible beam it isn't surprising that your friend is afraid that it may attract unwanted attention. We need more citizens such as him! If you really want...

I don't play it, but I won't knock it. It's probably pretty fun and augmented reality is a neat concept. It is funny hearing people at work talking about their kids playing it, and them helping their kids play it and about how there are some Pokestops or whatever they're called in the office...

I have to agree that two monitors are a must for coding for me. I do like the extra vertical space for seeing different parts of the same source file, but I really hate having stuff pop up over my coding window. I find that even with extra space on the primary monitor -- even more than having...

I've seen a few rare 16:10 monitors, but I haven't found any laptops besides Apple's that have 16:10 aspect ratios. They all seem to use that inferior "FHD" aspect ratio. At least Apple hasn't fallen into disgrace using that resolution, but I wouldn't be surprised if they switch over because...

Even with a giant screen I still use a second monitor. I just like having stuff off my main screen no matter how much space I may have. It's also nice for playing games and being able to see stuff on the second monitor. I also keep my (vertical) taskbar on the second monitor.

Hmm, most of the programs I've used, such as Photoshop and even old ones like Fireworks 8, can properly zoom down so I can see the pixels without much issue. If I really need inspect something I can also use the screen magnifier (Win + plus or minus). I found that 28" @2560x1600 monitors (or...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please They may also be dielectric mirrors for 633nm/HeNe lasers. I've seen that gold/purple color on some of the mirrors that Meredith Instruments was selling in one of their assortment bundles.

32" 4k computer monitors are quite nice though. :) I don't know if I'd want something bigger though. At two feet it is just right. Larger would just mean it would be further away and effectively the same screen size to my eyes.

Yeah, it is kind of a pain that way. I usually limit my strips to about 50 led (mine are 30/m) so that there isn't a huge variation in LED intensity due to voltage drop. That makes it about 300W per 20x 50-LED strips (30LED/strip). You can usually get away with less though, since that's for...

Yeah, some those IP67 strips have a small bit of diffusion. They certainly don't look as sharp as the IP-65 type

How did you figure that? Did you have any maximum permitted exposure (MPE) calculations to verify this claim?

Well I'm only partially "going to" by installing a separate drive to install and register Win10 with this computer's motherboard before they expire the "free" copy after July 29th. I still suspect that they won't really stop offering it for free, but whatever. Then I'll just swap back my old...

Re: WTB: Aspheric Lens 4/λ, 50mm or larger dia. + Infrared PBS cube, approx. 10-12mm Sorry about the late response. I should've been more explicit: I meant multiplying the matrices together. You can pretty much compute the entire lens system, including the curved interfaces at each side of...

There are those RGBW LEDs that are pretty nice. Have you also done some gamma correction and possibly used a library that does dithering (e.g. FastLED)? The dithering seems to work better for LEDs like the APA102-based LEDs and their higher PWM frequency. They seem have better color...

There are no goggles with which you can see the beam that will also protect your eyes, period. If you want to see the beam, the best thing to do is set up the laser (while off) so that it is secure, won't move, and is situated where nothing will cross the beam close up. Then put on your...

I'll buy CDs of artists I really liked, and to get a high quality rip of something that is hard to find, but most of what I have was not bought. It's also convenient sometimes. Plus, I can use the digital $1 "free credit" from not rushing things with Amazon prime to grab a single or two if I...

I can't remember what Winamp's pro version actually had that the free one didn't. The free one was pretty good in its day. Nowadays, I use Foobar2000. It has really good format support, customization, and plugins, and can even use Winamp visualizers like Milkdrop in it. I'd say it's the best...
