I know it doesn't look like much, but it's a lot cooler in real life. Taking an idea from someone else on this board, I got some Rustoleum paint from Home Depot, painted a board with it, and now, using my PHR laser, I can write with glow in the dark ink! Literally!

Just thought I would share... can't wait till I get a 12x to see that really work it's magic!
 





Cool! I've been meaning to do this for a long time.
How much was the paint at Home Depot?
I was there earlier today...
 
It was like $8.70.

Just make sure you get a good brush and some primer for Latex paints, if you are painting on wood or metal directly. And follow directions!
 
Cool I also have been meaning to do this and need to rember to buy the paint next time I'm in town, Thanks for sharing ;)
 
Yeah, it's really neat and cheap. Especially when you turn off the lights!

And hey, one of you guys with a 700mW 405... get some pictures for me, will ya? I won't be able to afford one of those diodes for a while... :(
 
That does look pretty cool :D well i havent found any GITD paint in my local shops yet but i will someday....

i also would like to see what a 1.3w 445 would do, im not sure if it will light it up or not.
 
Unfortunately, it wouldn't light it up at all. The only reason it lights up under 405 is because 405 is UV or near-UV, depending on who you refer to... and least, as far as I know. Glow in the dark paints only react to such ultraviolet colors... and 445nm isn't close to UV.
 
Really? My GITD board made from store bought zinc-based (I think) paint reacts
very happily under 445nm as well.
 
445nm works for sure. I have a glow in the dark ball and 1200mW of 445nm makes it glow very bright
 
THE INTERNET LIED TO ME!

Oh well.

I guess it makes sense that it would make it glow because it's such a high power than even if only a small percentage of the power is absorbed, it would still be quite a bit of energy.

But would, say, 100mW of 445 make GITD stuff glow?

Yes.
405nm is much better for fluorescence and phosphorescence but 445nm still works on many of the same materials. 473nm doesn't work very well for charging GITD since it is not energetic enough but it does excite fluorescence in the same things as 532nm (orange hi-lighters, pink post-its, etc.).

I think this is a good idea that nobody got around to doing. May I ask what power 405 laser you're using in the picture?
Also, I have a glow in the dark ball that did work under 445 light just to clear things up although I do read in a lot of places that 445nm doesn't make work at all. And have you ever seen a 405nm laser on a flourescence green fabric? I'll take a picture later tonight.
 
Huh. Interesting! Well now I know!

EDIT:

The 405 I am using is a low-powered PHR, running at around 100mA, so I estimate it to be at about 80mW.
