Rascal Micro hands-on (video)

Not far from the bustling labs of Northeastern University is the even more bustling hacker space known as Artisan's Asylum. The roughly 30,000 square foot complex is home to more than 100 makers, tinkerers and artists who building all sorts of crazy contraptions. One of the less ostentatious projects being worked on within its cavernous halls though, is the Rascal Micro. This tiny board is home to an ARM-based SOC and has its hungry, open-sourced eyes on competitors like Arduino and Beagle. Brandon Stafford, the creator, boiled down its primary selling points to this: "it's maybe 25 times faster, has 1,000 times more storage." Where as the Arduino excels at making things blink, move or Tweet, the Rascal Micro has enough power to function as a full-fledged web server.

SparkFun launches ProtoSnap MiniBot for the budding roboticist

SparkFun struck a chord with many when it released the ProtoSnap series last year. The perforated perfboard housed not only a tiny Arduino compatible chip, but a small host of sensors and components that made assembling simple projects a snap (pun not only intended, but relished). Tomorrow, the company will begin selling the next member of its ProtSnap family -- the MiniBot. Just like its predecessors, the ProtoSnap MiniBot is based around an Arduino compatible microcontroller (specifically ATmega328) and features a number of components that can easily be detached when you're ready to move from prototype to a more permanent arrangement. The onboard selection components is fairly limited. The base is a relatively bare perfboard with a 9v battery holder on one side and two wheels connected to a motor on the other. Up front is two IR sensors that can be used for basic controls.

Of course, it's simple enough to expand on the basic platform with any host of sensors and components, like servos or RF receivers. Ultimately it's up to your imagination and skill level, which is why SparkFun is primarily targeting the kits at the educational market. The company's new educational outreach program is making a big push to put the ProtoSnap MiniBot in classrooms across the country, starting with high schools and trade schools, as a bridge from more simplistic robotics kits to the more advanced projects tackled at the university level. The completely open source robotics platform will be available tomorrow for $74.95. As soon as we can get our mitts on one our own we'll return with a thorough hands on... one that reveals just how much smarter the average high school kid is than us.

Luminch One: an Arduino lamp you control with the wave of a hand (video)

A DIY lamp may not sound like the most thrilling project on Earth, but the Luminch One is special. Not only does this hand-made light from Francisco Castro provide illumination -- the most important function of any lamp -- but it does so while looking beautiful and providing a level of interactivity missing from most household lighting solutions. Underneath the pixelated-looking paper shade is an LED bulb controlled by an Arduino hooked up to an IR sensor. Simply wave your hand over the top to turn it on and off. You can also control the brightness by holding your hand above the stylized beacon momentarily to engage the dimmer, then moving your hand up and down to set your preferred lumen level. Check out the video after the break and head on over to the source for complete build instructions.

Matt Richardson turns Arduino, Twitter and lasers into art (video)

Matt Richardson's genius has never really been in question. The Make Live host and compulsive hacker has built an impressive library of creations, ranging from a Google Reader pedal to an email-triggered Christmas tree. The man's works are definitely art, in their own way, but his new project, Fade Away 1, is the first that we could easily see taking up residence in a SoHo gallery. At the heart of the installation is an Arduino (of course) that pulls in posts from Twitter with the phrase "fade away" in them. The same AVR chip then "prints" those tweets on phosphorescent paper with a UV laser mounted on a servo -- as the energy dissipates, the messages slowly disappear. And, if you're wondering what the "1" at the end of the title means, Richardson plans to continuously improve the project. For some more details about the next iteration and to see the current one in action, check out the videos after the break.

eSleeper combines cats, Arduino and Twitter in an eMac shell (video)

If we had to imagine our dream DIY project chances are it would involve Arduino, Twitter and, of course, cats. How we'd combine those things we're not sure, but we'll admit to being big fans of Samuel Cox's eSleeper, which turns a hollowed-out eMac into a bed for his feline. Inside the shell is an Arduino Ethernet connected to an IR sensor, some LEDs and a sound shield. When the cat breaks the infrared beam it triggers the iconic Mac chime and turns on a series color-shifting LEDs for a little mood lighting. From there the clock starts ticking. When little Fluffy (Captain Whiskers? Matlock? Penny? Greg?) decides she's had enough napping and leaves the white plastic cocoon, tripping the IR sensor again, a random phrase is tweeted, along with the length of the cat's siesta. Check out the video after the break to see the eSleeper in all its adorable DIY glory.

Add lasers to a tennis ball, drive your dog crazy (video)

It's a "programmable disco ball," a "cat toy for humans," and a "personal laser light show," all rolled into one. That's how one Matt Leone describes his latest creation, aptly known as the Laser Ball. To realize his dream, Leone drilled a set of holes into a garden variety tennis ball, and inserted about 14 laser diodes, each with an attached strip of diffraction grating. Said diodes were then synced up with an Arduino-equipped Teensy microcontroller nestled within the ball, alongside a rechargeable battery. As a cherry on top of this DIY sundae, Leone then incorporated an infrared remote package from Adafruit, allowing him to remotely jump start his next house party. The result is a cyborg-like ball that makes any LED cube look... square. Check it out for yourself, in the video after the break.

Tweephone is a rotary phone Twitter client, even your grandma could love

The collectives behind the Tweephone, UP digital Bureau and Unteleported tech agency, claim that it's the first analog Twitter client. We find that hard to believe but, while we've seen rotary phone-based Twitter tools before and analog meters that measure microblogging activity, we couldn't come up with a single example of a client that lets you punch in messages through non-digital means. Even if it's not the first of its kind, the Tweephone is still a pretty neat hack. Inside the old-school chassis is the ubiquitous Arduino, which interprets your pulls of the dial as letters. Like a phone with only a dial pad, you'll have to ring up numbers multiple times to get the right letter (i.e. dial "2" three times to get a "c"). It definitely not the most efficient method for sending out 140-character missives, but certainly one of the more unique. Check out the video after the break to see it in action.
