“You want to keep your noggin toasty in the nasty winter weather.
You don’t want to wear a hat that looks like everyone else’s hat.
You like lions (or dragons).
Now you can combine all of these desires into a simple, yet useful, item of clothing that’s infintely customizable and tailorable to your (or a recipient’s) tastes.” – Link.
“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.
“Brenda, my wife got me this stereoscope from an antique shop, they are pretty common. It didnt have any stereogram cards to look at or a holder for the cards. I had it for a while. Then this idea happened in my brain. I got an iRiver clix and thought, its small enough to fit on the stereoscope. Then I grabbed another clix, and made it.” – Link.
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. “
