iFixit Magnetic Project Mat
Here's one for your favorite tinkerer: an ingenious work mat that keeps screws and other tiny electronics parts safe and organized. The 8-x-10-in. mat has a dry-erase surface divided into a grid, so you can use the included pen to label each section for a different part or just make notes. Even better, the mat is magnetic, so parts won't roll off and disappear.
The Pro version of the mat (pictured) has the same footprint but includes a non-slip foam backing and a stronger magnet that can hold larger screws and parts. (If your giftee has a rambunctious cat, we recommend going Pro.)
