I liked it as well. Anyway his books are awesome and Tom Hanks as prof. Langdon is also great. Like he was born for this role IMO.

Awesome guys! Really makes me think about first build seeing this. ;) I'm looking to see further progress. :pop:

Yes, as I do. :) Reminds me Dan Brown's Angel and Demons - Antimatter | Angels & Demons - The science behind the story

So guys, there soon will be "antimatter delivery service" (something like pizza delivery). :D Just joking, but check this: Article: https://www.nature.com/articles/d41586-018-02221-9 Fastinating world we live in, don't we? Any ideas for experiments you would do with your pizza... eh...

Happy B-Day, Rich! :beer:

^^^This Lasers are not always the best solution - so try to ask on some "Aquarium Forums" as well to have more options of potential solutions. If you have many animals in tank, it might be easier to use something else than laser. You would need to put them in another tank in case of laser use.

Welcome to LPF! Check Sanwu, they might have what you are looking for. Do not forget to add proper eye protection to shopping cart with your laser. ;) Link: www.sanwulasers.org R.

Welcome to LPF Nick! Depends on what you wish to get. There are some companies being top in the industry of portables - Jet Lasers, Sanwu, Dragon Lasers and Optotronics (these are however very special and expensive beyond what you might need for start), further many members of community here...

I believe you will succeed here with awesome LPF community, just do not hesitate to ask for help. Anyway, I would not recommend to use 1 W greenie for close range. Check this one of my earlier laserpaintings: (Higher resolution under click on the pic.) Do you see the green lines on the...

Welcome to LPF! Have a nice stay here and do not forget to be safe with lasers. :wave:

Welcome to LPF! Enjoy and stay safe. Good you study everything, I do as well, no need for limit. You have entire life for studying and exploring this amazing world and lasers will learn you a lot, if you listen to the beauty of coherent monochromatic light. ;)

Or maybe cinema projector - just to be sure all pics on LPF will fit. :crackup:

That is on the post list of Laserpainting thread already. Hopefully sooner than later. :crackup:

Thanks, Bruce. I'll definitely let you know. So far I saw NYC just from the plane during landing when going to Mexico for cenotes scuba diving many years ago. Definitely city on to see list. And if you are going to Prague, let me know as well. We can see some places too. ;)

That is amazing! I would definitly go there, if NYC is not that far from me. Anyway tip in case I have a way to US again some time. Thanks for sharing this. It reminds me my laserpainting a bit, however laser does not go off under hit obviously and there is not 5 mW limit in my case. :D

Hi Swi, It seems to me the pics you added are of corrupted links. I do not see them. Those under points 1 to 5. BTW: I've checked BG for some optics and diffration gratings recently. Do you offer something like this?

I'm affraid there is no such a function on LPF yet. You need to crop/resize it on your computer and put the "LPF convenient version" of the image between BB IMG tags. You can edit the original post accordingly.

Hey man, please resize/crop those pics, they cannot fit screen even on computer monitor comfortably. You can always check preview of the post if it is comfortable to see. ;)

:drool: Just drooling how awesome this host is. Very precise boards as well. Damn it, you know I planned that 445 nm 7 W diode for large surface illumination in the future. Now I do not know - go with Grainde's host or with ArcticDude's host (still curious how would be duty cycle with this host...
