Came here wondering if a picture of spoiled canned ham was waiting. :tired: You deceived me! :mad: Also I'm hungry now. :pop:

Awesome. I know they have liquid filled optical stabilization lenses but I never knew they had something like this. I'm glad bobhaha is already going to test them so I can try to resist taking on another project. Really interested in this. :pop: If anyone finds a decent source for Liquid Lens...

Reject diodes that were intended to be 808 can range 700-900nm or more? Is there indication that they were really manufactured to be 808?

Meh.. In other cool computer news the $25 Rapberry Pi is only a ~month away! They have posted their Final PCB artwork & confirmed its credit card size (85.60mm x 53.98mm). :D

That focus ring looks very familiar. :) Is that a lasers4u module? Nice modules. The diode pocket is a bit deeper, allowing heat to be drawn back a bit more IMO. Also its built in o-ring is really useful for semi-waterproof/waterproof builds. They just cost a bit more then aixiz. :bumpit:

Adorable!

The thread title got me scared too. :tinfoil:

Really interested in how these batteries & your build works out. I love small builds & I've always been a bit uncomfortable with li-ion.

Those are some nice diodes & that neat green module is a cute little thing. ~Edit~ I see it is those ones with a doubled 1064nm diode.

Your drawing machine is pretty neat! :) It actually single mode or multi mode, there is no "dual" mode. All high power diodes seem to be multi mode. If you could find a single mode one it would likely be prohibitively expensive. CD,DVD,Bluray require single mode so any diodes that come from...

Can you pick your color or is it random with this seller? I don't see explicit mention of a choice. Where Guidesman always this inexpensive? How is the threads & overall quality?

Defocused 200mW would provide the same 5mW power over an area 40x larger. I'm not clear on whether you want laser light or if you consider led just as good. I know companies use both & I'm sure most will claim whichever one they use is better. Both leds & lasers are supposed to be powered with...

I have a couple of Rhd's 9mm diode clones, very nice modules.

If your considering using a DIY laser for medical procedures it will leave you open to lawsuits. Your malpractice insurance may raise your rates when they learn of it.

Most "5mW" greens aren't actually 5mW & could be well over that. Its easier to just take whatever power comes out after tossing it together & aligning. They have to put a "5mW" label on them to sell in the usa. If you good at disassembly (w/o breaking it) you can often adjust the focus. Be...

Multiple posts right after each other is usually frowned upon unless days has past. You can edit your posts to add new things. @ostbey Really interesting info / links & I've only been a few links so far.

I just happened to run into an IR 880nm LED light pad on ebay 880nm INFRARED LED LIGHT PAD HOLISTIC HEALING | eBay. It is way overpriced for what it is. A lot of people could build you one for much less. I personally don't buy the medical effects of light but you didn't ask for an opinion on that.

Nope, a projector shouldn't emit 880nm. Here is a 10mW 880nm laser. Perhaps they can lower the power for you. With its divergence of 40° x 10° be aware the beam will expand more in one axis (fast axis) creating a rectangular dot that will get wider with distance. A neutral density filter might...

Anyone trying to buy a 1-2W laser who seems inexperienced might get a hard time or questioned here. It's not personal. If that pisses you off then perhaps you have too much of a temper to be playing with lasers. In the hands of anyone without proper respect & experience these lasers are quite...
