Here Come the Halloween Hacks

We asked, you answered-the projects in our DIY Halloween contest include pumpkin bombs, pumpkin 'bots and one very disturbing pumpkin garment. Scary!

Halloween is officially here, and if you´re still scrounging for ideas with precious few hours until the march for candy begins, we´ve got you covered. Entries have been pouring in to our DIY Halloween Instructables contest, and whether you´re fashioning a costume made entirely of pumpkins or wiring up a USB-powered jack-o´-lantern, one thing´s for certain-Halloween really brings out the DIY spirit in everyone.

Launch the gallery to check out a handful of terrific ideas, ranging from the divine to the disturbing. And if you´ve been too busy in the workshop to share your most elaborate Halloween build with the world, there's still a week left to enter our contest[link] over at Instructables for fabulous prizes and plenty of All Hallows glory. Happy Halloween!

Smoke Screen

Just concluded a lovely evening of TP-ing houses when the angry owners start marching out? Toss these pumpkin bombs down the street and disappear in a cloud of smoke, leaving nothing but a burned-out squash shell in your wake.

Fish Face

Why look, it's everyone's favorite bioluminescent predator! Papier mache, Christmas LEDs and dollar-store flashlights--you'll be the fiercest fish in the sea.

Storm Clouds A'Gathering

Pearlized soap and a lightbulb--how else to make a dirt-cheap lava lamp? Dump in some fake eyeballs, and you're golden.

Mini Monsters

Take adorable plastic pumpkins, and slap them on top of potentially lethal spare electronic parts. Dr. Frankenstein himself couldn't have done better.

Pumpkin Pal

Poor pumpkins, left to fend for themselves in the harsh outdoors. How about giving them a break? Embed a USB-powered LED in the little guy, and let it join in that most hallowed of celebrations: Take Your Pumpkin to Work Day.

And for the Costume

We debated putting this one in, we really did. Bonus points for not requiring any suspenders to keep those pumpkin-pants up.

And, Pull

What's a terrifying haunted forest without a working drawbridge entryway? Lame! Raid your friendly local abandoned barns for the appropriate frame, loop in some giant chains and Tiki torches, and laugh maniacally while small children traipse through.

Stone-Age Speeder

Don't dress your kid up unless you plan to do it right. This spot-on replica of the Flintstones' caveman cruiser is made from swim noodles, plywood, Bondo-Glass and a ridiculous amount of grandparently affection. Taking some artistic license, they even put in a pair of seatbelts. Too bad the kids will outgrow it in a month.

Blowhard

Puketacular! Thread a hose from a bucket of dry ice through a pumpkin's mouth, and enjoy. Nothing says "Happy Halloween" quite like a vapor-spewing Jack.

LED Shrooms

Phew, just in time! Toggle among three colors of embedded LEDs, and rake in the benefits. 1-Up!

Ray, and Drop that Golden Gun

As we can well attest, mad scientists need rayguns. Some creative caulking of candlesticks and lamps, and you too can go forth and damage.

Kreepy Komputers

Nothing like a little All Hallow's Eve resurrection. For a geektastic holiday, nothing can beat some bodywork and a well-placed full-screen image (transferred via floppy disc, of course).

Lightning in a Box

Wrap an ordinary bulb with mesh, and then up its wattage by feeding a high-voltage discharge through its base. Creating your own potentially lethal lightning--what could be scarier?
