Batteries of any ilk cost money, while I have buckets of old wall warts. As is, my cost for AA and AAA batteries just for keyboards and mice and 357's for calipers and the 2032's for remote controls is north of $100 a year plus the hassle of going after them. Locally, the batteries these lasers use are $15 a set of 2, and made out of fairly pure unobtainium. I found just 4 of them in an afternoons search of the local merchants. Bought them all. $40.
So I'll go ahead and make a slip ring and brush holder, probably out of local scrap Teflon. That I've grabbed anytime its been available for a couple decades. Often free because most don't know what it is, its just slippery white plastic to them. My biggest problem will be fitting the slip rings tight enough to stay put. Theres no locally available glue that sticks to Teflon. Thanks Andy. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
