Hi guys,
I'm a carpenter by trade and have a small pet peeve that involves my nail guns. Every time I climb a ladder and hold a massive lump of timber in just the right spot, my God damn nail gun has no nails in it. It happened twice today (and a lot of other days). I need some ideas for a small long battery life sensor so that when the sensors line up with say 3 nails left, it lets out a beep. I've always thought this should have been standard on these thousand dollar guns for years now. Any ideas?
