Verizon Users Shout “I Am Root!”

Droid has been rooted. It was only a matter of time but we do like to celebrate this sort of thing. Why? Because if you pay for it you should own it. This will probably spark a flame war about licensing agreements and such in the comments but answer this: if it breaks, who pays to fix it? If you’re the one paying for it, you should be able to do what you want with it.

The process seems simple. Copy the magic file onto your SD card and go through the firmware upgrade process. Just make sure you know what you’re doing so that you don’t brick this sexy device.

Robot Hands You Your Ass At Beer Pong

Guess who built this contraption? You’re right, college students. But as much as we like to make fun, the subject of Beer Pong is our addition, not theirs. The device uses an air stream that can be directed along two axis to control and sort ping-pong balls.

Unlike the lethal ping-pong ball launcher, the goal here is elegant control of the ball. They’ve achieved a great success. Watch the video after the break to see balls sorted into beakers by color, transferred to vessels over a large distance, and navigated through an elevated obstacle course. To give us a hint of what you can do with this, we see the machine controlling an apple, an onion, and a water bottle at the end of the video.

Fully-automatic Crossbow

[youtube=http://www.youtube.com/watch?v=QS4RKoRyTik]

We received an excited email from [Noah] regarding a gentleman who works with crossbows and crossbow pistols. Begrudgingly, we took a look and what we saw made our day. [TheDuckman666] must have an insatiable love for all things crossbow. His webpage has details and pictures covering seven different models that he built. His YouTube channel shows off three more models, all with magazines for multiple bolts.

Seeing the electrically-cocked, automatic projectile launchers wets our appetite, but we do wish there was more background info about the build process.

Creating Wooden Enclosures

[Matthias] built a wooden enclosure for his keyboard. He’s used to using a Commodore 64 keyboard and decided he didn’t need the num pad found on modern keyboards.

It’s not the finished product that interests us, but the methods he used to create such a nice looking enclosure. From the wooden binary adder he produced we know he’s a talented woodworker. He takes us step-by-step through the use of a scroll saw, table saw, and router tabled to turn out this one-of-a-kind. You may not own these tools but someone you know does. Follow his example and turn out your own wooden wonders.

Ionocraft Aka Lifters

It’s hard to believe that in five years we haven’t covered lifters before. This realization was sparked when [Tyler] tipped us off about a lifter project demonstrated at the Kansas City hackerspace called CCCKC.

Lifters, the casual name for ionocraft, fly without combustion or moving parts. We’re not going to tackle the particulars of what makes flight possible, but high voltage is required to feed the phenomenon that provides the lift. One of the first comments when we asked what to do with old CRT monitors was to use them for lifters. The flyback transformer puts out plenty of voltage if you can tap into it without killing yourself (no, seriously, that’s an issue).

This is the method that the CCCKC folks used. Take a peek at the video after the break. If you’re thirsting for more fun with lifters, stop by the Lifter Project.

Water The Tree – There’s An App For That?

Well no, but [Chris] needed something to remind him when to water the tree. Most folks would use their nifty iPhone to set up a calendar reminder, but why do that when you can purpose a 32 bit microcontroller to do it for you?

To detect a falling water level [Chris] attached a two-pin header to the end of a clothes pin clipped to the side of the tree stand. When the water level is covering the pins it completes a circuit, verified by a measurable current. When the water level drops the mbed microcontroller detects the loss of conductivity and through some creative code sends out an email and SMS reminder.

If you’re in love with your iPhone but not your living things, this will keep that tree kicking until after the new year.

Simple Liquid Dispenser For Auto-cocktails

[Qdot] came up with a simple way to dosing out liquids to use in his Bartris project. As you can see above, flexible tubing is connected to some inverted bottles that house the liquid. A chopstick is attached to a board on one end, and via string to a servo on the other. When the servo turns it pulls the chopstick tight against the board, cutting off the flow of liquid through the tubing. This isn’t as elegant as the system the Bar2D2 uses but it’s a heck of a lot less expensive.

You can check out some of the build pictures in his Flickr pool. He’s included this concept in a project he calls Adult Mario. Watch the video after the break but the quick and dirty is that the more coins you score in Super Mario Brothers, the more beverage is rationed out into your cup. Ah, human lab rats, is there nothing they won’t do for booze?
