So, about two years ago I showed up here because I was trying to build a laser harp and sniffing around for parts/advice. I got such a nice welcome that I had to come back today when I FINALLY got the darned thing working and show you all the result:

So now I'm just looking for a more powerful, but still affordable, green laser. The one I bought way back in my innocent youth was, I am almost certain, a bit over-advertised when it came to the claim of 300mW...
Anyway, thanks all!
