As guys said. The 532 nm looks yellow to orange. With my high OD goggles even Opto Beast looks like tiny orange dotie. No glare, no green, just fluorescent light. Without goggles it would blind you instantly...

Seems as dust on lens. Depends if on outside or inside. Try to use photographic cleaning/blowing balloon at first attempt - filtered, otherwise you will bring more dust in. It is important to do it in dust free room and with lens facing down. I clean my lasers in bathroom after shower (wait a...

Yeah, that glass pyramid is something else. And even holograms are kind of illusion - like (perceived) reality itself is - created in brain. Anyway thank you for your help, Paul. I'm about to use jpeg compression in combination with higher resolution on one detail from the artwork. This should...

No, I do not wear glasses for a few years now. However I suffered with headache few years ago. It was about a month with no single sun ray here. I went to optitian and my eyes were allright according to their tables. They were surprised how accurately I needed to set the correction for sharp...

Re: Radim's Laserpainting Art & more How to see it? Since I have not received any reaction so far, maybe this is because you cannot see it. The latest artwork is considered as first step show to get inside it. It uses leading optical illusion (order of pics, texts, other screenshots with...

Oh my god... I was asked by my mum to print some of my art as a birthday gift for her friend. So, I used the latest artwork The Pandora's Black Box and to test the holograms on others as well. I've just returned from the photo store, where I printed it in 4 versions (two matt and two glossy)...

The Pandora's Black Box Details taken from my laserpainting artwork: The Shape Of The Surreal World ...the shape of the soul... Note: For higher resolution click on the pic. ;)

Thanks Bob, I hope that thing won't be bigger than I'm. :crackup: It is always a risk when you are playing with complex systems and thinking too much (still too tired - just a few hours slept since Monday). :D And that's planned and thank you for not leaving me without that, I cannot leave it...

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele 473? DPSS rulez. ;) Beautiful beam. Thin, strong and great quality - JL Ple Pro. ;) Yeah, and overspec. Awesome laser. Kind of a bit of heating and eating batts like T-Rex and velocirapotors (both together)...

No buts in safety otherwise you will burn your butt. :crackup: Just joking. Great you take safety serious - this is the first thing when it comes to lasers. :) You've got some tips already, so there is a lot of lasers to choose from. Enjoy. ;)

I use it mostly for menu in restaurants when travelling and not knowing local language. :D

This.^^^^ Or you can build one from new 18650s. Definitely do not mix different types and/or ages of batts.

Not sure about second board. I would again identify ICs and get some idea from it. Especially the big one. Or you can get some translation app (google translate) for mobile and try to take a photo of the chineese writing - the app should translate it. Link for more...

Linear Technology - Product Page Looks like simple Zener. For powering the first bug. Reference.

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Hey, guys... I just want both - I still have to reward myself for my big job project stage 1 finished. :crackup:

That is how I would do it:
