What do you get when you put an ultra-bright LED in the palm of a glove, and strobe it controlled by an accelerometer? A Time Control Glove! In creator [MadGyver]’s own words, it’s “just a stroboscope with frequency adjustment” but the effect is where all the fun is.
The Time Control Glove uses the stroboscopic effect, which many of us have seen used in timeless water drop fountains where the strobe rate makes drops appear to change speed, freeze in place, and even change direction. [MadGyver] made the entire assembly portable by putting it into a glove. An on-board accelerometer toggles the strobe in response to a shake, and the frequency is changed by twisting the glove left or right. The immediate visual feedback to the physical motions is great. The whole effect is really striking on the video, which is embedded below.

[Sam] is an avid Halloween builder and has been hard at work on a time-machine simulator for this year’s festivities (alternate link). He recently assembled the enclosure which is seen above. It’s got room for two riders who will be strapped in place, with plenty of interior items to keep them occupied. There will be three LCD monitors acting as front and side windows for the time machine.
In the video after the break (taken from his vblog on the page linked above) [Sam] walks us through all of the electronics that went into this. He’s got red lights controlled by a servo motor attached to a dimmer switch. There’s a vibrating seat to give the riders a jolt, and a control panel which shows the status of the time machine. The thing is, it’s not just the physical build that’s impressive. We know from his past projects that [Sam] is a showman and he doesn’t disappoint this year. He spent a lot of time filming and generating computer graphics and sound to really make the ride a multimedia odyssey.

With today’s release of Security Update 2008-006 Apple has finally addressed this summer’s DNS bug. In their previous update they fixed BIND, but that only affects people running servers. Now, they’ve updated mDNSResponder. Clients are no longer susceptible to DNS cache poisoning attacks thanks to the inclusion of source port randomization.
The Security Update addresses some other interesting bugs. Time Machine was saving sensitive logs without using the proper permissions, so any user could view them.
