Hello you guys,
anyone ever consider making a two (or more) mode, high and low,
variation of the popular lm317 DIY driver?
I thought it would be nice to have on a highpowered pointer, such as
a 445nm diode or an 8-12x Bluray.
You know, one mode to point around with (relatively) safely, and one
mode to BURN!
Say, 300ma & 1200 ma.
or 50ma & 300ma
As a switch, I figured a micro-sized slide Single Pole Double Throw switch on the outside of the host.
What would be REALLY slick is a reed (magnetic) switch, which would be
invisible from the outside, and the pointer would be in "safe"-mode until you
cling your magnet to the pointer!
Eh, Eh? whaddayall think about that!?
If only I could source a reed changeover rated for 1.5A...
EDIT:
hey this one might do the trick...
