The folks down at LVL1, the Louisville hackerspace, are throwing a Halloween party. To showcase his building skills, LVL1 member [JAC_101] put together a Halloween diorama featuring the inner workings of Doctor Frankenstein’s laboratory.
There’s a bunch of really neat pieces that make this build great. First up is the LVL1 plasma sign. This sign is four circuits pumping a high voltage charge through Xenon flash tubes. Instead of a bright flash, a very Halloweeny Xenon plasma shoots though the tubes. The sign is constructed from four disposable camera flash circuits.
A few flickering-LED torches light Dr. Franenstein’s lair while the monster is a McDonalds happy meal toy wrapped in surgical tape and painted with UV reactive paint.
In the interests of repurposing existing materials, a plasma disc belt buckle was taken from
[Seven of Nine]’s regeneration chamber LVL1’s rave supply cabinet and provides a suitable ‘mad scientist’ aesthetic. A bit of EL wire was thrown in for good measure along with some black lights to activate the UV paint.
While Frankenstein’s lab is missing a hilariously oversize knife switch on the wall, [JAC_101] still pulled off a great build.
Forget flashlights, and leave those burning lasers at home, [Ben Krasnow] built a search light using a 1000W xenon arc lamp. That box you see on the side of the trash-can housing countains a starting circuit that shoots 30 kilovolts through the xenon lamp to get it started but it is separate from the power supply. [Ben] started experimenting with the lamp back in April but recently finished the project by using the inverter from an arc welder to get the 50 amps at 20 volts needed when the lamp is on.
The insert on the left of the image above is an outdoor picture of the beam. You can make out a tree at the bottom. Take a look at the video after the break for a full walk-through of the circuitry and some test footage of the finished product.

In a hack worthy of the flick Kick Ass, [Chein] built this arm-mounted light weapon. The lamp in the palm of your hand has a ring of LEDs for a nice glowing effect, but the real story is the xenon bulb at its center. The flash capacitor and charge circuit from a disposable camera are used to step up the battery voltage to 330V for an intense and slightly blinding discharge. The charging is started when you press a button on the back of the hand harness, with the flash coming when one of your fingers touches a conveniently positioned trigger. Check it out after the break.
This non-lethal weapon makes for a nice alternative to the dangers involve in playing with fire.

Joystiq has been tracking the new starlet of Xbox 360 failures: the E74 error. It appears as the lower right light on the console turning red and an on-screen message telling the user to contact support with the error E74. The number of reported E74 errors seems to have risen since August 2008 and people are wondering if the more recent increase in errors are related to the release of the New Xbox Experience (NXE) Dashboard update. Did Microsoft reclass Red Ring of Death (RROD) failures as E74 to avoid warranty replacements? Continue reading “Hackit: Xbox 360 Hardware Failures On The Rise?” →
