contest

Since we inaugurated Guess This Tool, you've all proven way too hard to stump, so for this week's contest, we're mixing it up a bit and giving you a mystery part rather than a tool.

Are you looking for that little extra "something" to kick your entry up a notch in the upcoming PopSci/Instructables Halloween contest? Then you might want to consider some professional help. No, not a therapist, rather a Cordless Pumpkin Carving Tool by Dremel.

Carving's its name, and pumpkins are its game.

We are happy to announce the latest winner of PopSci's rolling reader photo contest: Owen Wolter.

The theme for the next contest is Spooky Science -- let's see what you've got! Upload your entries to our Flickr pool

There are many prizes to be won in this year's Halloween contest, but we know you're most interested in the big kahuna: The Tech Grand Prize includes a $250 Shopping spree at the Maker Shed Store, a $250 gift certificate to Plaid Craft Express, and a $100 gift certificate to Hack N Mod. So get your tech tools out and start impressing the PopSci.com judges (that's right kids, we're in on it)!

It's a mere 50-some days till All Hallows Eve. Huzzah! Time to dust off your bioluminescent thinking cap, strap on your fanciest pumpkin duds and get hacking. Just like last year, we expect to be floored by you ingenious folks. And, just like last year, grand rewards (lest fame and glory fail to entice) await entrants.

Were excited to announce that were launching a special PopSci.com contest with Bug Labs, the folks behind BUG, the open, modular consumer-electronics hardware and Web-services platform that you can use like Legos to build practically any gadget you can dream up. And even more exciting, the grand prize will be a BUGbase and the first batch of four BUGmodules!
