If you want to give your children all the opportunities you can for a successful life, you can get them this DIY RFID kit to teach them all about nitty-gritty technology, all while allowing them to learn about privacy on their own. Of course, there's also a pretty good chance you'll be dooming your offspring to a lonely life of tech-nerdery. But hey, it wasn't so bad for you, was it? Right?

In any case, the DIY RFID kit should be loads of fun for nerdy kids and adults alike. It includes everything you need to track your household objects. Tags, scanners, and software are all included, giving you the tools you need to set up an alarm for every time the dog that you've implanted a radio tag in enters the house. Sure, your kid'll go to the prom alone now, but he'll probably get into MIT as well. It's a tradeoff. — Adam Frucci
