No matter what holiday you choose to acknowledge, you probably enjoy the thought of getting to put lights up everywhere. We know we do. Here are some instructions on how to make your own string of color changing lights. Sure, you can probably just buy a string of color changing lights for cheaper, but then you couldn’t arrange them however you want on the line, and you also wouldn’t get the satisfaction of doing it yourself.

We pretty much don’t know anything about this POV device other than it uses 96 LEDs. We’ve seen POVs with more LEDs, but usually they aren’t packed in so tight. This thing looks almost capable of displaying low res movies. Wouldn’t this thing be cool, and probably dangerous, in a hat?

The DS1077 is a 5volt, 133MHz to 16kHz programmable clock source. The internal frequency divider is configured over a simple I2C interface, and the chip requires no external parts. Not bad for under $2. We used the Bus Pirate to test this chip before using it in a project. Grab the datasheet (PDF) and follow along.

[jelengar] liked the ease of use of the Arduino, but wanted a much higher pin count. He set about converting the ATmega Controller for use with Wiring, the code that the Arduino IDE is based on. The ATmega128 in the controller features 53 pins as opposed to the 11 on the Arduino’s ATmega168. You also get 128kb of memory. The process is fairly simple; you just need to add the appropriate crystal. You can also add a switch to trigger the bootloader and a status LED.

While the iPhone 3G included several new features that its predecessor lacked, one thing it did not include was a dock. Instead of shelling out $30 to buy Apple’s iPhone 3G dock, [Roland] and the folks at Geeky-Gadgets.com decided to design their own cardboard iPhone dock. While this doesn’t include any fancy features like dock connectors or audio line-outs, it looks like a quick and budget friendly way to give your iPhone 3G a place to charge and sync.
WEEE Man is an art display that has been roving around England. No, he doesn’t walk or talk. He is here to remind us of how wasteful we can be. Hackers rejoice, we’re part of the solution. It also doesn’t hurt that he is Seven Meters tall and over three tons. WEEE Man looks awesome, but are we the only ones that spotted stuff and thought “ooh, I could have used that for a cool project.”?

Apparently you can revive dead Ni-Cad batteries by zapping them with high voltage. Some people have used welders in the past, but many of us just don’t have access to one. This project shows you how to hack a disposable camera into a battery revival device. This could be very cost effective. A single regular AA battery could revive many Ni-Cads. Remember, this doesn’t charge them, just makes them able to be charged again.
