Yes Indeed! I am saving old PC boards out of computers and whatever old electronics I get my hands on. Even Bigger yet, I reclaim electrical components of most types. That stuff is really expensive if you have to buy like 2-3 pieces. These are FREE. I got some old car/truck parts at dad's and most of it was heavy. I had 2 large trash cans, one was full and the other 75% with crushed aluminum cans. I was saving from everyone who would give them to me. It was maybe 5 years worth of cans! It all adds up, a little at a time, Right Big Ed? ;)
