Gee, what happened to all those guys that were building LED flashlights in Altoids tins?, Watson et al?
They were a big presence here a year or so ago.
Perhaps they started their own group?
Curious in Connecticut.

They probably decided to just go to WalMart and buy one for a couple of bucks and move on in their lives. ;)
In Connecticut,Mass,NH and RI you can find them for $1 at OSJL

Yes, I know where to get flashlights.
I was jusr curious about all the whereabouts of all the experimenters. They kept this group h>>

The Chinese influx.

Perhaps. But good, cheap, well built high intensity flashlights are still rare. I own one a 1.5W Aurora flashlight I bought a couple of years ago for $40. The best I've ever owned.
The latest ones look even better:

Run off by the flames, mostly. Watson appears from time-to-time in s.e.b., methinks, and has a flashlight building blog out there somewhere in cyberspace.
Ahh, here it is:

Hell, I'm still at it! Getting a Luxeon K2 emitter running from a tabaco tin is amazing - its a lot brighter than the cheapo ones.
There's not much room in a tin for batteries and an current source and the lamp though so run time is pretty limited.
IMO the problem is designing a good case. The electronics seem simple these days.

IIRC,there's an online forum for LED flashlights. ...there are so many driver ICs to choose from these days.

Maybe their dentists told them not to eat so many Altoids?
