DIY 3-way Hi-Vi tower loudspeaker project
Adam has constructed a pair of 3-Way Tower Speakers using all Hi-Vi drivers. The speaker enclosure is divided into a bass reflex portion that contains a single Hi-Vi F8 Woofer and a sealed portion that contains a the pair of Hi-Vi F5 mid-woofers and a Hi-Vi SD1.1-A tweeter. The sound is divided using a 3-way 2nd order crossover network.
The speaker enclosure is using MDF and finished with black oil based epoxy paint and red oak trim, thanks Gio! Link.

Arduino - NGAutoReset
Here's how to auto reset the older Arduino NG's (just like the new Diecimila) -
If you have an Arduino NG and you're envious of all the seconds saved by those Diecimila owners who don't have to press the reset button anymore, this page is for you. You can upgrade an Arduino NG to take advantage of the auto-reset functionality in Arduino 0009 and beyond with just a 0.1uF (100 nano-farad) capacitor and a soldering iron.Arduino - NGAutoReset - [via] Link.

HOW TO bleach a shirt the WoW geekery way
Sykora writes -
/flex is one of my favorite WoW (World of Warcraft) emotes. Often, the programmers made this emote way over-the-top, and funny to watch. It's also rather instantly recognizable in silhouette, which made it a good subject for this shirt.HOW TO bleach a shirt the WoW geekery way - Link.

Bare Bones Arduino Diecimila mod
David Fowler of uC Hobby writes:
A new version of the Arduino board was released that added a cool new feature. With help from Paul Badger of Modern Device Company and Brian of the Freeduino project this article will show you how to modify the Bare Bones Arduino board to make it compatible with the new Diecimila Arduino. No more pressing the reset button to load your code and no more long waits to see if it runs.

Make a pocket LED cube - Weekend Projects Podcast
This week, Bre Pettis teams up with Mitch Altman and George Shammas to make a little 3x3x3 cube made of little LED lights that you can program with any kind of animation you like! - Subscribe Link
Update: in the podcast I say you need a yellow purple brown colored resistor (470 Ohm). I need to get my glasses checked because actually you need a yellow purple black (47 Ohm) resistor!
Update 2: It has come to our knowledge that James Clar is the initial creator of the 3D LED Cube. He is a lighting designer that has done many things with technology lighting and his works can be seen at: www.JamesClar.com You can view his patent for the 3D Cube with the wiring schematic at the USPTO patent # 7190328

HOW TO - Build your own Chaos Machine
A Double Pendulum, a.k.a. a Chaotic Pendulum, is a simple, jointed pendulum used to study dynamic systems/chaos theory. It's also just a really cool widget that's fun to watch.
Not to be confused, BTW, with Steve Jackson's (of Steve Jackson Games fame) Chaos Machine, which is an entirely different mechanical animal.

Homemade jet engine
Hmmm. Beer and garage-built jet engines. Is it just me or does this look like an accident waiting to happen? That is one angry motor.
BTW: There are dozens of similar engines on YouTube. Search on "homemade jet engines." Few of them look quite this... dramatic.

Defconbots autonomous sentry gun
Kevin Hjelden and his friend Joe built this autonomous shooter for this year's Defconbots competition. They described the build before they started:
The electronics for this project are going to be relatively simple as well. To control the three servos (pan + tilt + firing), we are going to use the Pololu 8-channel servo controller. Normally we might use an atmega to do the control, however I already created code to control the pololu controller for another project and it's really inexpensive/easy to use. If it required more complicated feedback or logic, a microcontroller might have been the better choice, but in this case it wasn't, so the right decision was just to use the Pololu controller. To control the valve, we had two options. One was to use another channel on the servo controller and something like a Banebot motor controller to apply power to the electronic valve, the other was to use the servo that pushes the plunger to push a switch that opens the valve. The latter option was chosen.

SlugTerm - A Terminal for a Slug
Phil writes -
This page describes how I've solved the problem of adding an interactive terminal to my Linksys NSLU2 (aka Slug) with a USB keyboard and an LCD display. My soltuon consists of some C++ code (about 1000 lines) and some hardware to attach the display to USB. I hope that it will be useful to other Slug users.SlugTerm - A Terminal for a Slug - Link.

External enclosure with custom microcontroller
Al writes -
A homebrew microcontroller to monitor a computer's hard drive usage was originally posted on Makezine back in Feb. of 2006. This apparently generated a spark. A reader created a very attractive project based on that with some creative customizations using SATAValut from CoolDrives.External enclosure with custom microcontroller - Link.

Breaking down and repacking a 36V battery pack
SLK Electronics has a piece on their site about breaking down a DeWalt 36V A123 high-power Li-ion batteries to make your own battery configurations. This (and several other related articles on the site) is gear towards electric model planes, but is obviously applicable to any application.

HOW TO - Make "Ice Gems"

Make your own 1952 Fraction-of-an-inch adding machine
Evil Mad Scientist Laboratories writes -
Last weekend we took a trip to Urban Ore in Berkeley, where I found an incredible gem: this "Fraction of an Inch Adding Machine." It's a simple to use device that lets you add any number of fractions-- from 1/64 to 63/64-- quickly, automatically, correctly, and without thinking about it.Make your own 1952 Fraction-of-an-inch Adding Machine - Link.As proudly proclaimed on the bezel itself, this calculator design is covered under patent Des. 169941, submitted in 1952, and granted a 14-year term in 1953. Forty years after the patent has expired, it's painfully obsolescent, and yet remarkably charming. The design is so simple and so obvious in how it works, and yet... there's something almost magical about it.
But enough talk. Want to play with one? Using our pdf pattern and some office supplies, you can make a working replica in 5-10 minutes and try it out yourself!

Make your own ringtones with iTunes
This is a good direction, the new version of iTunes will allow you to make your own ringtones. There will be ones for sale of course but this is the way it should be... Until it comes out I'm not sure what the restrictions are and how it works on purchased/non-purchased (can you make your own ring tones from plain old mp3s you own/ripped from CDs)...? - Link.
