[Jack Toole] and his team [Aaron King] and [Libo He] sent in their computer interface dubbed the Chronos Flying Mouse. The video above explains the concept very thoroughly, but we’ll reiterate some of the highlights here. The project uses a Chronos EZ430 with its accelerometers to wirelessly transmit delta positions of the user’s wrist. Add a little open source software and you have a regular PC mouse, a video game joystick, a game wheel, and a few other different devices in one. We just love the suave feeling of snapping to click.

PCB Trace Antenna

August 5, 2010 by Jakob Griffith 19 Comments

If you’re working on a device that includes RF wireless, [Colin’s] Guide to PCB Trace Antenna Design might clear some headaches when sending off for PCBs. While it is directed at devices transmitting at 2.4GHz, the techniques and recommended equipment (read: espresso smith charts and network analyzers) should work for almost any frequency. While trace antennas aren’t as easy to implement as a measured wire, the space benefits make up for the difficulty. Unless you don’t mind how larger your project is, did someone say cantenna?

All Metal Hot End For Makerbot

August 4, 2010 by Jakob Griffith 19 Comments

Imagine if you will for a moment, you’re printing along on your Makerbot clone and all of a sudden your PTFE hot end melts, what are you going to do now? One solution is to mill your own all metal end from a bolt with some careful drilling. Or you could follow [Peter Jansen] who has made his own all metal hot end using the existing extruder. All that’s required is some aluminum sheet and cutting down the nozzle and hat (and fans to help, but technicalities), and you’re in business with no more melted PTFE hot end.

Hardware Hack 3D, Software Still Needed

If you’re on the fence about 3D TV and related technologies [Anton B.] might be able to help you decide. No, he’s not going to shove pamphlets in your face and explain why its the wave of the future. Rather, by showing the hack-ability (its a word) of 3D shutter glasses. A simple bridge of wire across specific contacts can ‘trick’ the glasses into only displaying only the left or right picture.

Wouldn’t that make it just a regular 2D TV again? Yes, that’s the beauty of it. Person A could be watching a completely separate movie pr0n than person B, but all on the same TV. Or two people could be playing a video game, without dividing the screen in half. The only problem is the current lack of software that can interlace movies/games, who’s up for writing some C++ this weekend?

Jailbreak Your Apple Products

August 2, 2010 by Jakob Griffith 31 Comments

It’s finally here, after being declared completely legal to jailbreak your iPhone, JailbreakMe 2.0 is released.

Now, any and all iDevices can be jailbroken by simply visiting the URL above; however, before you start your devious adventure in the land of apps not approved by big brother Apple, there are a few issues.

The webpage is being slammed at the moment so you’ll have to wait. There is a chance the jailbreak will not work, and you could brick your phone. MMS and Facetime are having complications after jailbreaking. And finally, carrier unlock still needs to be done with ultrasn0w.

But beyond those small stepping stones, jailbreaking is just a touch away.

Save A Baby, Nursery Temperature Monitor

August 1, 2010 by Jakob Griffith 36 Comments

Yes, you could argue this Nursery Room Temperature Monitor is simply an LED and an Arduino with a temperature sensor, but [Jay] really did put more thought into the process. For instance he stuck with AVR, built a wooden base and sanded globe, and even included schematics and source code. Plus, SIDS is no laughing matter and the more you know, the more it can be prevented. Back on point, one thing we would add is PWM for a more gradual change in color. What would you add?

Elegant Wearable Computer

July 30, 2010 by Jakob Griffith 50 Comments

[Jason Statham] [Martin Magnusson] wrote in to tell us about his adventure in building a wearable computer. The device in its current state is a Beagleboard running Angstrom Linux tethered to an iPhone for internet. A bluetooth keyboard allows for input, while output is displayed on monocle-ized Myvu. And last but not least, the entire setup is powered by 4 AA batteries for 3 hours of life.

Its not as small as some of the wearable computers we’ve seen before, but if you wanted to whip out your own it sure takes a lot less soldering.
