Shake control your music - Wii remote + Linux
Walter sent is this fun way to control your music, he writes -
"Today I hacked my christmas present. A Wii remote controls my xmms mp3 player in linux now. Shake the remote and it switches to a new song.
To get this working in ubunto linux you need the following packages: WMD driver 0.1.2 xmms control python files written by myself. Read the README's in the .tar.gz's for install instructions " - Link.

New shield connects Phidgets sensors to Arduino board
Bjoern writes -
"I just received my first Arduino Shield PCB design in the mail from Advanced Circuits. We have lots of Phidgets sensors lying around in the lab; they may be a bit pricey, but their plug-and-play model is sure handy when you're in a hurry. This PCB makes it easy to connect these sensors to the Arduino platform. The board has six Phidgets (aka 3 pin Molex C-GRID) connectors which are routed directly to the Arduino's A2D ports. It also breaks out 8 bits of digital IO to .1" headers and provides the all-important reset switch and status LED." Thanks Kevin! - Link.

Wave Bubble - Open source Wi-Fi, cellphone, GPS and Bluetooth RF jammer
Some folks go caroling on Xmas, others release open source hardware projects, like this one... A RF jammer -
"This website details the design and construction Wave Bubble: a self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camoflauging: it is the size of a pack of cigarettes.
An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). The battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). Alternately, 3 AAA batteries may also be used.
Output power is .1W (high bands) and .3W (low bands). Effective range is approximately 20' radius with well-tuned antennas. Less so with the internal antennas or poorly matched antennas. "

HOW TO - Make a music syncing light orb alarm clock
Max shows you how to make a music syncing light up orb clock, he writes -
"Okay, we have seen some really cool Light Orbs while trying to make this Music Syncing Light Orb Alarm Clock. We started with Tod's creation and soon realize that 1 LED will not be bright enough in slightest light conditions though his Light Orb is tight let us say. So we checked out RGB lights at Hackedgadgets.com. Which is cool and uses 4 Red, 3 Green, and 3 Blue LEDs.
Well during our google search for Light Orb HOWTOs, we came to the Ambient Devices schematic and their technical notes. Well it says that with the right voltage, you don't need to use resistors.
During our breadboard testing, this proved to be costly. We went through about 20 nice High output LEDs trying to match the forward voltage of LEDs... " - Link.

DIY Wii mega-tv
Jon writes -
"One of my friends is a manager at a local movie theater, which uses a digital projector to show advertisements between features. After seeing the It Burns When I Wii video, we figured we could one-up it with the equivalent of a 344" television screen. We wanted to use my friend's Nintendo Wii in the theater, but we didn't want to have to deal with yards of cabling. Inspired by doctabu's design, I built my own wireless sensor bar for less than $20." - Link.

Roombas go caroling
Tod and his bots send some seasons greetings, he writes -
"The Roomba family was out caroling. They stopped by and sang a few songs. I caught a few on tape. I think they were a little tipsy on mulled 30W or something.
This was a demo of RoombaMidi2, a Mac OS X program to turn your Roomba into a MIDI instrument. Click the link to find out how and get the source code (and find out why they were so drunk)." - Link.

Nixie tube ornament
Ian made an awesome Nixie tube ornament -
"The Nixie Tube Ornament is a homage to the light-up&motion ornaments from the early 90's. The ornament looks cool on a tree and makes a great gift. Finally, a use for IN-12/15 top view tubes!
I used an IN-15A symbol nixie in this ornament. An IN-12 works great too." - Link.

Wii EEPROM hacking & a wish list from Spark Fun Electronics
Spark Fun Electronics poked at the EPROM on the Wii, fun stuff--
"We just couldn't not do it. We had to see what was on the Wii EEPROM. There's surprising amount of 8051 instructions actually. How neat!
We hot-aired off the EEPROM and soldered it down to our SSOP breakout board. We then hooked up the unit to an AVR micro that could handle the I2C communication and clocked out all the I2C data from the M24128 into the AVR and down the serial pipe to the computer and captured it. You will find the binary file here. My bet was that the EEPROM contained all constants like Bluetooth ID, firmware revision, etc. And that all the fun Wii Remote functionality was burned into the Broadcom part. David's bet was that the Broadcom part was just the Bluetooth HID stack and protocol and that it pinged the EEPROM during boot up for actual Wii Controller firmware. We were both right!
Looking at the binary file, the fun thing to note is the word 'Nintendo' a couple thousand bytes into the file. Boy would that be fun to alter. The real kicker was that we found unencrypted 8051 code in the file. We don't know if it is checksumed or anything, but you should be able to hack away. This seems to indicate that the entire Wii Remote functionality is contained on this M24128 EEPROM. Nifty." - Link.

Hand crank - Drill power!
And0 writes -
To prepare for a 2003 doomsday "pole-shift" scenario, a group of survivalists put together this "Troubled Times" information hub. One neat idea caught my eye: using an old power drill as a makeshift hand-crank generator."
From the site:
"The unit is light weight (2.5 lb), portable, low cost ($10-$20) and can be used to recharge single cell batteries at from 1-3.5 amps. It can be made from a cordless electric drill in a primitive environment. The simplest way of how to make a hand crank DC generator using a standard 12, 14.4 or 18 Volt Cordless drill from Harbor Freight Tools. With no modification hook an alligator clip jumper to the two charging terminals (on the bottom that the battery plugs into). See picture below. Note that when a 14.4 Volt drill is laid down pointing to the left then the upper terminal is most likely to be the plus and the lower terminal the minus for these units." - Link.

HOW TO - Make your own DIY cables, XLR, TRS, studio cables
DIY-Central shows you how to make your own XLR, TRS, studio cables
"Looking to save some money? Create your own cables! By spending a few dollars on jacks, shielded cables, solder and soldering iron, you can save a ton of money in cables.
It's easy. Here are some step by step photos.
At the bottom of this article, is a wiring guide for XLR to XLR, XLR to TRS, XLR to TS, and whatever combination you can think of.
On this guide, I'm wiring up an XLR cable. First, we disassemble the cable by unscrewing the lock screw. Pull out the rubber plug (black thingy) and then you'll be able to push out the 3-pin connection assembly."- Link.
The site has a lot of other great projects to check out too - Thanks Ruel.

Open source PulseVU for Wii
Pablot writes -
"This is the first hardware mod available for the Nintendo Wii. It's called the PulseVU for Wii and is an internal chip that takes control of the light bar on the Nintendo Wii. It fades the lights when the console is off and pulses them with the audio when the console is on. It is open source with schematics and instructions, or you can get your own manufactured version for cheap. The site has a video of its features, as well as a large FAQ, links to the source, and links to the install instructions." - Link.
