I could recommend ReadyMade Magazine because it covers a pretty huge spectrum of stuff and ranges all over the place. It's pretty fun. Some of it is for the home, clothes, pets, electronics, gardening, etc. Their Plug It section might be where the more fun stuff is. They also have quite a few ideas for repurposing stuff. Of course there's also Popular Science and Popular Mechanics. You can view the older Popular Mechanics on Google, and if you go waaaaay back, you start finding some really cool stuff. I was looking at a 1928 issue today actually. Pretty fun.
