Large magnets spark on Halloween, who knew? This overly large magnet certainly completes the mad scientist look (for an even crazier look, take a jar of water with red food coloring and place in one large cauliflower, instant brain in a jar). The base of the magnet is painted foam cut with a makeshift hot-knife; [...]

BBB #1: The Santa-pede challenge Welcome to the first Buy Break Build at hackaday, sponsored by Adafruit Industries and Make. This challenge will be focusing on dancing Santas, or what is inside them. We’ve seen them everywhere, and may even have one or two in an attic somewhere.

Unreal speaker build These speakers are hand made and almost one of a kind. [Lluís Pujolàs] didn’t come up with the original design, but he sure did an amazing job of crafting them, including an eleven page build log (translated). They’re called the Odyssey 2, after the original design. The shell-shaped cavity on the bottom was built [...]
Portal…shirt? [Ben Heck] is in the Halloween spirit with his Portal inspired “see through” t-shirt. That is, a thin lcd is mounted on [Ben's] chest, with a not as thin camera mounted on his back; when the system is running, everything behind him is captured by the camera and displayed on the LCD. The concept [...]
Gas containment for laser cutters Tired of breathing all the noxious fumes your laser cutter puts out? Yeah… we don’t have a laser cutter either. But [Jeri Ellsworth] does and she needed a way to evacuate off-gases generated during cutting so that they don’t damage the laser cutter, or her lungs. What she came up [...]
Hackaday links: October 24, 2010 Square Gears This video demonstrates square gears and other oddly shaped cogs. We can’t think of a use but it’s interesting none-the-less. [via Tinkernology] Cooking with Lasers It’s late and you’ve been at the workbench for quite some time. But why go to the kitchen for a snack? Grab a [...]
Marx Generator, knocks our rocks off What weighs more than 500 pounds, produces 500 kilovolts, and we don’t recommend you try at home in any way shape or form? If you guessed a rock disaggregation device, you’re correct! We also accepted lightning generators as correct answers. Using high voltage electricity, a rock can be split [...]
Halloween props: Pumpkin in standby-mode Evil Mad Scientist Laboratories is preparing for Halloween with this standby-mode pumpkin. Inside there’s an LED plugging a hole that is drilled just to the skin of the gourd-like vegetable. It fades in and out similar to a sleeping Mac, using what we think is a vastly over-powered circuit based [...]
