Weather canvas
|
|
Another Cornell final project, Weather Canvas aims to make watching the weather a little more pleasant. Data is captured via a thermometer, humidity sensor, anemometer, and a Hotwheels radar gun turned precipitation sensor. Once it’s captured, it’s transmitted to the LED matrix inside which displays pretty patterns to convey the weather conditions. They have set

iFob: Keyless entry

[Nate] hates keys. He’s gone through a lot of effort to remove them wherever possible. He has a keypad at home and a keypad at work, but he still has to carry car keys. His solution is to build a device he can carry in his pocket that will unlock the car via RF. To

Laser cut drum kit
|
|
[Segwaymonkey] picked up an arduino based drumkit circuit and needed a kit to place it on. He worked up a pretty cool design and had it laser cut out of acrylic. The cool part of the design is how he delt with the head motion of the drum. Each head has 4 “springs” that were

Wireless portable USB tether

[Pete] has put together a fairly simple writeup on building a wireless USB tether for your DSLR. He’s basically using a pair of USB wireless adapters and a battery pack. In his original version, he did some slight modification to the dock that powers the USB dongle, adding his own battery pack too. He notes

Folding hexapod bodies
|
|
At Berkeley, they’re coming up with new ways to make their itty bitty hexapods. These are basically tiny flatpacked bodies cut from cardboard. The end goal is to not only make them smaller and faster to build, but to reduce the friction in the joints. You can download the files on their site as well

[Ladyada] has released this tutorial on using pressure sensors. They cover everything from the basics of their construction through how to connect and read data from them. The elegant sensor pictured above is available through the adafruit store, but you could always build your own.

Digital Dice
|
|
There have been several attempts at bringing Dungeons & Dragons up to date with modern technology. Most attempts have been in the form of computer games that somehow fail to capture the essential experience. This attempt, however seems to add some techie flair to while keeping the game the same. [Itay] has built some digital

Color detection using an RGB LED
|
|
[Kyri] has made a simple circuit to do color detection using an RGB LED. Simply set the LED to the color you want to detect then wave the object over it. Another LED will light up if the object is the same color as the LED. The detection is done by a photo resistor. The

D-Link router captcha broken

We reported last week that D-Link was adding captchas to their routers to prevent automated login by malware. Unsurprisingly, it doesn’t work all time. The team from SourceSec grabbed the new firmware and began poking at it. They found that certain pages don’t require the authentication to be passed for access. One of these is

[Marc] submitted this project he’s been building. It’s a web enabled HVAC monitoring system. He’s using a pic-web development board with a custom I/O daughter board to control the HVAC system. The project allows for the system to be monitored and controlled via the web. It should be able to interface with most commercial and

Laser overkill, iPhone style

Ever wanted a projector for your iPhone? How about a laser projector? These guys did, they made one using an individual laser for each pixel. They have a 5×7 grid to work with, so they have to keep it simple. Well, as simple as it gets with 35 lasers. We think maybe a scanning POV

Goggle camera mod

Snoozy the Sloth

Snoozy the Sloth clings to you and sleeps. While this may sound easily done, the maker wanted the sloth to actually simulate breathing with exhaled breath to add to the realism. To do this, they had to build a “respiratory system” out of a rubber glove, a solenoid, and a couple pumps. This kind of
