Stop wasting your air freshener.
Airwick air fresheners come with an amazing feature. They spray air freshener every once in a while no matter what. It is extremely wasteful and obviously a marketing plan to force you to buy more. There is a solution though. You can hack them, to turn them back in to a manual release like they used to be. Two cuts and two soldered wires is all that is necessary.
yes, we know you could just buy an aerosol, but many of us just come home and find them in our bathrooms since someone else in the house bought it. If you’ve already got it, why not hack it? This is also a great project for teaching beginners how to improve hardware.

Sound activated christmas lights.
Christmas is coming up pretty quickly. [tinkernut] shows us how to do a quick and dirty music activated Christmas light setup. Simply crack open a pair of old computer speakers and wire the speaker leads to a relay. Use that to power an outlet and you have music controlled lights. The section at the beginning of the video is a bit misleading as that kind of choreography would be rather difficult with this setup. This may look familiar as we mentioned an almost identical project back in 2006.
Since we last reported about The Great Internet Migratory Box of Electronic Junk, several of these boxes have begun circulating in different areas of the world. Team Hack-a-Day launched three themselves. Robots.net decided that there was a need for a specialized box just for those who hack robots, and have launched their own.
The box contains lots of things that will appeal to roboticists, such as servos, various sized motors, RC car parts, and even a small microcontroller board. Plus hackable items like old CD drives, a trackball, and miscellaneous electronic and hardware parts. Everything fits in a standard sized shipping box, but it is full. A complete list can be found on the robots.net site, and they also have pictures of the contents.
Those who wish to track the box can follow it under the name robots.net-box1 on the TGIMBOEJ wiki. There is also a place to get your name added to the list of potential recipients. The wiki contains information about the whole process, including how to start a new box.
Wiimote finger tracking music controller.
The Evolution Control Committee has been doing live mashup performances for many years and recently upgraded their hardware. Inspired by [Johnny Lee]’s Wiimote whiteboard, they built a rear projection display they could use during performances. It displays a dense collection of samples in Ableton Live. On each of the performer’s hands is an IR LED mounted to a thimble. By touching the thumb to the forefinger, the LED turns on. Two Wiimotes watch for these IR flashes to trigger mouse clicks. [TradeMark G] found the Ableton display too complex to navigate quickly and accurately with a mouse; this new display make things much easier and enjoyable.

[Casey Pugh] with the help of a few friends constructed a Daft Punk style helmet for his Halloween costume. Embedded above you can see a timelapse of LED matrix construction. The 16×5 display is driven by an Arduino.

Nintendo DSi gets its first flash cart.
A month ago, we reported that Nintendo’s new DSi portable didn’t work with any of the current crop of flash cartridges. Things didn’t look good for homebrew. Here we are a month later and looking at the release of the Acekard 2i. It’s the first DSi compatible flash cartridge. The features appear to be identical to previous versions and we expect other manufactures will be updating their product lines in short order. You can find a video of the Acekard 2i after the break.
These carts may exist because of pirates, but we happily use them for homebrew. There are a lot of great programs out there; here’s a list of 24 apps that are dedicated to music creation. You can run Linux on it too. It’s as easy as copying a file to a flash drive. If you have a DS and aren’t using homebrew, you’re wasting it. We’ll be picking up a DSi as soon as they’re in the US (they’re region locked).

Firefox addon makes pirating music easier.
The Amazon MP3 Store may have the lowest prices on DRM free music, but for some people 79 cents for a song is just too much, especially when [john] and the folks at pirates-of-the-amazon.com can help you get that song for free. Pirates of the Amazon is a slick Firefox addon that inserts a “download 4 free” button next to the “add to cart” button in the Amazon MP3 Store. After clicking on the button, the addon refers users to a thepiratebay.org search page with bittorrent download links for the song or album. While there is no question that this makes getting your music easier, by using this addon you do run the risk of violating copyright laws, depending on which country you live in.
There isn’t much here that hasn’t been thrown into Greasemonkey scripts in the past and we wonder if they’re marketing this to anyone at all. People who absolutely love using Amazon but hate buying stuff perhaps? They cite a couple interesting projects in their about section: Amazon Noir robotically abused the “Search Inside” feature to reconstruct entire books. OU Library searches your local library to see if it has the Amazon book you’re looking for.
[unusualelectronics] posted this animated LED snowflake. It has 61 LEDs, is controlled by a PIC microcontroller, and can perform about 30 different effects. The instructions are quite thorough, including diagrams for soldering and source code for the microcontroller.
[sixerdoodle] sent us this nice firefly project that serves as an intro to charlieplexing. We’ve mentioned charlieplexing before, in our LED Life post and the Breath Controlled LED candles post. This project is quite simple and focues mainly on how to make a charlieplexed circuit work.
The goal was to create a tiny firefly bottle with SMD LEDs and as few wires as possible. In the video, after the break, it is hard to tell just how small this thing is until we see the battery. There are clear directions and fantastic pictures detailing exactly how to set up a charlieplexed circuit with 6 LEDs.
Great job [sixerdoodle], thanks for sending it in.
Wii Drum High, Wiimote drumming.
[HE Zao] sent us this sweet Wiimote Drum kit. You’ll nee a Wiimote, a Nunchuck, and a Balance Board to use with the the Wii Drum High software. You get a Hi-hat, snare, bass drum, crash cymbal, ride cymbal, mid tom, and low tom. You can even connect multiple sets, up to 4. Download the software from the site and get started.
Inside Nokia’s hardware damage labs.
Like everybody, we sometimes get a little frustrated with our cellphones. Probably one of the most annoying things is when we drop our phones once and they stop working. At Nokia’s hardware damage labs in San Diego, they physically test their phones for extreme uses. They test things like flip tension, water resistance, and even UV resistance. Recently, the folks over at MobileCrunch were given a tour of these labs and were nice enough to post an in-depth article about what they saw. In addition to the impact testing video above, there are many more videos posted that demonstrate the tests they perform.
Python 3000 officially released.
Python 3000 has officially been released. The final bug, Issue2306, “Update What’s new in 3.0″ has been closed. Python 3000, py3k, Python 3.0, is a major release for the community. [Jeremy Hylton] pegs the earliest mention of the beast to January 2000. The new release has grown from PEP 3000, opened April 2006.
Py3k breaks backwards compatibility with previous releases in order to reduce feature duplication and promote one obvious way of getting things done. The first major change is that
intandlonghave been unified, and integer division now returns a float. Py3k uses concepts of “text” and “data” instead of “Unicode strings” and “8-bit strings”. You can read about many of the changes in What’s New In Python 3.0. Some new features have been backported to Python 2.6 so you can start implementing them in your current code to ease the transition. 2.6 also has the-3command line switch to warn you about features that are being removed or changed. Finally, the tool 2to3 is a source-to-source translator that should automate a lot of the changes.Documentation for the new release is online. Source packages and binaries are available now.

A couple months ago we posted [Ben Heck]’s in-progress photos of his Xbox 360 laptop (with links to his other versions). He’s just put the finishing touches on it, and dubbed it the Xbox 360 Portable. It has a removable hard drive on top and memory slots on the side. The webcam is embedded in the frame and there’s internal WiFi. With chatpads available now, he’s decided not to include a keyboard. It’s really a nice machine. Check out the video below for a tour of the system.
Winboni, a window cleaning robot.
The Winboni is the first place winner in the International Student Design Competition of the American Society of Mechanical Engineers. Winboni is a small robot that cleans windows. That alone doesn’t set the robot apart. The fact that it is held on by suction is what distinguishes it. Running off AA batteries, this robot clings to the window as it cleans it with felt pads. It is hard to believe that this isn’t already a commercial product. Actually, we thought we had even seen it before, but we can’t find it now.

[Guy John] sent in this cool sequencer project. He’s using the game Go as the input. A web camera pics up the location of the pieces on the grid and plots them in his sequencing software. You can see that it is still very much in progress, but it is coming along nicely. He openly admits that it may never be completely practical. There is still so much to be improved to get it even comfortably usable, such as motion detection to remove his hand from the mix when re locating the Go pieces. This project is very similar skittle interface that we posted back in july. It would be kind of interesting, though probably repetitive, to actually play a game of go and listen to the variations in the music while you play.
Refresh.
