Have you had it with Fido’s stink? Need some relief? Are you a sucker? Well, the Pet Collar Air Purifier can help. It takes that filthy air around your animal, sucks it up, and spits out clean air.

The purifier will save you and your pet from allergens, dander and smoke and also coats your dog, cat or whatever with spray from a scent dispenser that will relax them. And do god knows what else. It can’t be good.

We love video games around here. Whether we’re playing the Xbox 360, the PS3 or even an old Atari 2600. We thought we would take a look at the history of gaming consoles from 1972 to the present. You grew up with the vintage consoles, you play the new ones, so take a walk down memory lane and revisit all your favorites from the massive list below.

The Float-a-Pet collar is a good idea. For one thing it keeps your pet safe, for another it’s fun to see pet heads floating down Main Street during a flood. Win/win. It’s an inflating floating emergency collar with a flashing light so you can locate your pet even in the dark.

Sure, dogs can swim, but that doesn’t mean they don’t get tired, just like us. It may not be such a great idea that the flashing light is powered by solar. Probably not the best way to power something that is made for emergency nighttime situations. But with this thing, at least your pet has a chance to become one of many floating heads in a flood situation.

Sony took the wraps today off an expanded line up of its nav-u personal navigation devices. These new models – the NV-U94T, NV-U84, NV-U74T and NV-U44 – price around $400, $350, $300 and $250 respectively and will be available in September.

Sony says new features of these four just added nav-u GPS units include more brand icons, search functionality and photo viewing features. The top dog of this group is the NV-U94T, adding “a photo viewer, audio/video player and stereo Bluetooth technology for streaming audio and making hands-free phone calls using compatible devices.” You can get full details on these models after the jump.

Sometimes the coolest gadgets in Sci-Fi are not gadgets at all. But robots. Here’s a look at some of the most memorable robots from sci-fi in no particular order. It’s not a complete list. Think of it more as a walk down memory lane. Because geeks love Sci-Fi and Sci-Fi has a long history of loving robots.
