This is a solution to a problem I definitely have - I often find myself wrestling with coffee and a few gadgets, without enough hands to hold it all. This DIY sleeve takes at least the coffee off your hands.
It's basically one of those coffee sleeves you get to keep from burning your hands, but with a few strong magnets embedded inside. So if you need an extra hand to tie your shoes, fiddle with a smartphone or PMP, you can just stick your coffee to the nearest street lamp. And it looks like it might be even more protective for our delicate nerd hands than those wimpy cardboard ones. [Lifehacker]
