Sorry it took a while but I updated my location. The popcorn would ship from somewhere in the USA, but I don't know exactly where.

I'm a Life Scout, I should have mentioned that earlier

Dear LPF community, I am currently a member of Boy Scouts but, scouting has gotten more and more expensive over the years and that combined with having a difficult year last year my budget has gotten very tight. I don’t want to have to quit scouting but it is starting to look like I might have...

I have brought mirrors into those vault games and they don't work. I tried to figure out why when I noticed that you could 'break' a beam without touching them. So I took a closer look at the system they had and it turned out to just be a ton of cheap motion sensors. The best way to cheat...

well on a brighter note, I would like to say good luck to everyone trying to build/sell these boost drivers, and also to everyone who is trying to learn more about all there different driver options.

WOW, that's crazy... I Can't wait to see that thing finished +1 for such a great build!

Why isn't this a sticky yet?

Ya, I agree with Bluefan. But personally I would just buy my own pair of safety glasses and encourage my class mates to buy some as well.

If you use a solar panel then you wouldn't have to deal with expensive/dangerous lasers and complicated aligning/focusing...

you could use the cap from this host 5mW 532nm Green Laser Pointer Pen with DX Logo (2*AAA) - Free Shipping - DealExtreme or this one www.rayfoss.com They are the standard new wish hosts and the cap they have should fit your module.

Glad you like your new laser. Nice Review

OMG, that was EPIC my life will never be the same. Now I am going to watch some more laser shows. :pop:

OK this one might be easy if you are an astronomer. No hints because this is an easy one.
