A new twist: I took the batteries out of the 5mW (the ones fresh at noon that now produce only a feeble green glow) and installed them in my 20mW laser. It produces a bright beam! So now I'm thinking that it's an intermittant problem with the diode itself. Hmmm. On Thu, Feb 21, 2013 at 8:15 PM, Chuck Hards <chuck.hards@gmail.com> wrote:
Just to be sure that I didn't put in two pair of dead (but new) batteries, today at lunch I bought another pack of brand-new AAA cells and installed two of them. Tonight at 8:00 PM, the batteries are dead.
