this is done - all spoken for.
but feel free to PM me if you want some - if there's enough interest I'll make up an order for some of the really tiny switches, 1/4" long - better than what I got on eBay - but will cost 75c each + mailing expenses (unless I find another cheap source)
Got some tiny magnetic reed switches really cheap yesterday (25c), and did a little testing... found that a DX neodymium mini-magnet will activate them at about 1/2 inch distance through shrink tubing. So... my next laser will have a built-in hidden switch that will change it from a 5mw pointer to a 200mw burner just by moving the magnet from the tailcap to a different spot on the body!
Goldmine has these for a buck each, but I've seen them somewhere else cheaper than that.
ah, found some eBays:
eBay
I just bid on them... if nobody competes they'll be about $0.20 each after postage - cheap enough to send out a couple free to anyone sending me a stamped envelope. We'll see.
