MintyPOV
How to make an Altoids tin version of the MiniPOV! -
It seems that everyone and their mother is cramming various projects into mint tins these days. Well, that's a bandwagon that I just couldn't resist jumping onto. The only question was what project to build?MintyPOV - Link.I ordered a MiniPOV3 kit from the Makezine Store, a while back. After building it and playing with it, and letting my kids play with it, and repairing it a couple times after the kids played with it, I decided it needed a case to live in. Realization struck. The first thing I did was check Google to find out if it had been done before. As far as I could tell, it hadn't, so I started gathering parts.
Rather than mess up my original kit, I decided to scratch build the circuit on perfboard. I used LEDs that I had harvested from a string of LED christmas lights, resistors and other bits from various sources, and the requisite mint (Wintergreen flavor) tin.

Light as you type
Another strange USB device. This lamp changes its color and gets brighter depending on how fast you type. Despite the fact that your LCD screen will probably give you enough light to see what you are doing, this lamp might be more useful if it was hacked to generate a small desk fan that cooled you as you started sweating from all of your typing hours.

HOW TO - Make a Tesla coil plasma gun
Design news latest "Gadget Freak" shows you how to make your own Tesla coil plasma gun -
Here's a gun that can light up an unplugged fluorescent bulb or spark electrical storms in an unplugged incandescent bulb -- the same effect as a plaza globe. Richard Morrow of Cheshire, England, built the Tesla Coil plasma gun using the casing of an inexpensive cordless hand drill. He uses the trigger of the hand drill as the plasma gun's trigger. The device is powered by a 12V battery. The high frequency, high voltage from the gun causes the argon gas in light bulbs to become ionized, which creates streamers that are attracted to the fingers holding the bulb.Tesla coil plasma gun - Link.

New stuff @ SparkFun electronics
SparkFun just opened up a huge can of newness - here are some of their latest that I thought was worth checking out...
You knew it was coming. The Port-O-Rotary has dropped in price for the holiday ridiculousness. Black is $200, red is $250. But wait, there's more! These new units have a built-in fast charger (no more opening the case). Pick up the handset and you'll hear what no other cellular phone has - a dial tone! - Link.
If you've ever played with Atmel AVRs, you may have discovered how annoying the two different ISP (in circuit serial programming) interfaces can be. We designed this simple interface board to allow you to connect basic 10-pin programmers to 6-pin devices (think Arduino and LilyPad). We also included an inline connector for easy AVR breadboarding! - Link.
This is a ScreenKey - a programmable button that can display any graphic with a backlight that is itself configurable to be a handful of different colors. We have both RGB and RG versions. So cool - Link.

Blinkin' USB port made from a candy LED treat
AlphaA writes -
Okay. So, this isn't my most impressive project. But, it's so simple and silly I believe others could have fun with the idea, just as I have. I have found something to do with unused USB ports. I call it U-S-Blink and they are quick, easy and cheap to make. This is another product of boredom. and some solder. I used an old RadioShack PCB which was laid out like a protoboard/breadboard and a Flashing LED snagged from a blinking lollypop once I finished devouring all of the sugary deliciousness.Blinkin' USB port - [via] Link.

iRobot Create personal home robot
We're a little late posting this, but check out the winner of the iRobot Create contest! -
iRobot Corp. today announced a winner in the iRobot Create Challenge contest. Built using the iRobot® Create® Programmable Robot, the winning entry, titled "Personal Home Robot," was designed to make life around the house more convenient and entertaining. It can water plants, control lights and appliances, play music and remind owners to take medication. The robot's creator, Danh Trinh, 35, of Towson, Md., won $5,000.iRobot create personal home robot - Link & press release."This is an excellent example of the enthusiasm people bring to the idea of building robots," said Helen Greiner, co-founder and chairman, iRobot Corp. "Contestants put in amazing efforts creating exciting and imaginative robots for the challenge. We saw everything from robots that serve food and drinks to robots that paint pictures and can be remotely controlled from distant locations."

Make a Joule Thief - Weekend Projects Video Podcast
This week, Windell Oskay of Evil Mad Scientist Laboratories joins me to teach you how to make a super clever little circuit called the Joule Thief! The Joule Thief allows you to squeeze the life out of what most people think of as "dead" batteries!
We were inspired by Big Clive to make this project and it's the perfect platform for a flashlight, book reading light, or really just something you should make to get more use out of your batteries!
Update: Windell posted more info and a detailed walk through of the toroid winding process. Check it out before you make it! - Link

Chip hacker blog
Bunnie writes -
Flylogic Engineering now has an interesting blog up on chip hacking! If you liked the posts on my blog about chip hacking, you may very much enjoy the postings at Flylogic. They've actually got a very nice piece up on the PIC18F1320 which reveals new findings about a device that I have some prior familiarity with. I'm looking forward to reading part II of their series!- Flylogic Engineering's Analytical Blog - [via] Link.

Critter board reference released
Critter and Guitari have released their boards...
...We are releasing all PCB schematic and layout files, including Gerber files for everything in the Critter Boards category. All designs are done in Cadsoft's Eagle layout program -- a free version of this program is available. This good news comes with some bad. For a variety of reasons we will no longer be selling small quantities of Critter Board development tools. This is unfortunate, but to keep support for those interested in building self-contained music/video instruments, we've decided to open up everything.

Tooth Tunes Musical Toothbrush dissection
Steve writes -
The Tooth Tunes Musical Toothbrush plays two minute pop song clips to help kids count down an appropriate length of tooth brushing time. Suspecting that this used a transducer to conduct the sound through the bristles and into the jaw (bone conductance) I wanted to both know for sure and see how easily it could be hacked, so I bought one and took it apart. Here are photos of that dissection. The audio IC is potted so I suspect it will be hard to change the sound which is played, but I think the transducer itself could make for a fun little toy. The sound quality is decent when the transducer is held directly against the teeth, the head, or any large, flat surface (eg: workbench).Tooth Tunes Musical Toothbrush dissection - Link.
