Lightsaber Boasts Detachable Blade And Crystal Chamber

December 30, 2010 by Mike Szczys 23 Comments

[Bradley W. Lewis] continues to amaze us with this Return of the Jedi Lightsaber build. You’ll remember his fine work from his previous Episode IV replica. He’s taken the parts that turned out well for him and expanded upon them. In the demonstration after the break you’ll see the new version has a removable blade (which happens to house 90 LEDs). Just like the last time he’s got a Hasbro sound board and a speaker to add the Jedi-like sound effects. But there’s another trick up his sleeve. Two parts of the grip slide apart on a spring-loaded assembly to reveal the crystal that gives the weapon its sting. And as we found out the last time, [Bradley] really knows how to share his work in the build log.

Oh, and the drawings above? Well, someone who plans this meticulously obviously knows what they’re doing.

Adding A Serial Port Through An RJ45 Connector

December 30, 2010 by Mike Szczys 21 Comments

[Mike Lu] likes to add serial ports to his routers to use for debugging but he didn’t want to drill holes in his new RT-N12. After a bit of head-scratching he thought about repurposing the four unused wires on one of the RJ45 Ethernet connectors. This would allow him to interface with the necessary signals and still have the option of using that port for a network connection. The first step was to build the circuit to output the correct serial levels and connect it to the unused pins on the jack. Next, to separate serial and Ethernet on the outside of the router he build a short adapter cable.

This is an elegant solution if you’re looking for zero case modifications. But if you don’t mind a few inconspicuous holes we love the serial port used on this Dockstar.

Lego Pinhole Camera

December 30, 2010 by Mike Szczys 8 Comments

[Bshikin] built a pinhole camera out of Lego pieces (translated). It is a fully automated unit thanks to the integration of the NXT pieces. It took a bit of careful calculation to get the film spacing adjusted to match the focal length, and quite a bit of tape was necessary to keep light out of the film chamber. But in the end, it’s an amazing build that takes decent pictures. The software has settings for film size and speed, and takes care of exposing and advancing the frame at the click of a button. See for yourself after the break.

If you hunger for some more camera building goodness check out this SLR hand crafted from scratch.

IPod Nano 6g Closer To Being Cracked

December 29, 2010 by Mike Szczys 32 Comments

[Steven Troughton-Smith] figured out how to push signed firmware through to the iPod Nano 6g. This is accomplished by modifying iRecovery to recognize the device on the USB after forcing a recovery mode reboot. So no, this doesn’t mean that it has been cracked since it checks the firmware you push and reboots if it’s not approved. But if you can figure out how to craft a custom image that passes the check you can call yourself a jailbreak author.

Custom Made Industrial Hookah

December 29, 2010 by James Munns 44 Comments

Since their invention in the 1500s, Hookahs have always been a way for craftsmen to show off skills by creating ornate, elaborate, and functional pieces of art. This still holds true today, as easily seen above. Found on the Hookah subreddit, this pipe was pieced together by recycling an old vodka bottle, as well decorating and re-purposing a number of plumbing items. Some finishing touches such as LEDs and gears to the base, as well as a set of turn-valves to the hose plugs give this hookah a very distinctive look.

As always, we at Hackaday do not recommend or promote smoking, no matter what goes into the bowl of the hookah. However, whether you smoke or not, the final product is worth appreciating. Be sure to check out the higher resolution pictures after the break.

A Tricycle Built For Plowing

December 29, 2010 by James Munns 27 Comments

What do you get when you combine two bikes, a couple levers, and a home made wooden shovel? Why, a light duty tricycle plow, of course! [Craig] of Firefly Workshop cobbled together this contraption to assist him in shoveling his 90′ driveway when a few inches fall. More convenient than a normal shovel, and much more environmentally friendly than his 8 Horsepower snow blower, this trike looks like it could actually make shoveling the snow fun. Not really much more here than meets the eye, we just wish we had a video to share of this sweet ride in action.

Bringing The Shark To The Bee

December 29, 2010 by James Munns 12 Comments

Wireshark, a tool recognized universally as being one of the best network analyzers available, has long been used by legitimate network professionals as well as a shadier crowd (and everywhere in between). While useful for analyzing both wired and Wi-Fi traffic, monitoring 802.15.4 protocols (such as Zigbee) have not been a common use in the past. [Akiba] of FreakLabs has brought us a solution which works around the normal limitations of Wireshark’s libpcap base, which does not accept simple serial input from most homebrew setups that use FTDI or Arduinos to connect to Zigbee devices. Using named pipes and a few custom scripts, [Akiba] has been able to coax Wireshark into accepting input from one of FreakLabs Freakduino boards.

While there are certainly professional wireless analyzing tools out there that connect directly into Wireshark, we at Hackaday love showing off anyone who takes the difficult, cheap, out of the way method of doing things over the neat, expensive, commercial method any day.
