I've got old cell phones and a couple laptops. I don't plan on making much, short term, but the more BTC satoshi I can get while it's down, the better. (Even if it is psychological, and I am technically not making as much.) Still, I have seen plans for making low power solar panels for charging cellphones and other nearly free ways to charge a cell, so I can bring the costs down massively. When I start making them, I'll write a post about it.
