Hasta La Gadget!

“Magical Tooth” adhesive crooked canine caps from Japanese cosmetic accessories company Luvlit are designed to make wearers look younger, cuter and more attractive than ever before… and not just to vampires, either.

An LED Matrix Display is a very affordable and versatile tool for showing information. But Stephen Wylie and Stacy Devino made an even more affordable and useful version of it. They call it LEDgoes, a display that you can expand by snapping modules together like LEGO.

Each module measures 1.5″ x 2″ and has 35 LEDs that can display red, green or yello. You can connect boards in real-time and even stack up to two rows as one. They also each have two ATMega microcontrollers as well as 26 hackable GPIO pins.

Out of the box, you can type a message to display on your LEDgoes using a PC or mobile device, or you can sync it to a Twitter or RSS feed. But because they’re ready to be hacked, you can make your own apps and display whatever you want on them.

Pledge at least $29 (USD) on Kickstarter to get a LEDgoes kit with two small display panels as a reward.

While you won’t get rich running a single Raspberry Pi Bitcoin Rig, you can probably make back your initial investment in this ingenious little machine. RaspPi Bitcoin rigs are nothing new but Dave Conroy has just built one and, more important, shared his plans in a fairly easy-to-read page.

The system uses the Pi as a main processor and a 330MH/s ASIC. In total he spent $127 on his kit and, as far as we can tell, the power outlay will be negligible.

The system uses an ARM-centric mining OS called MinePeon. It is basically a version of Arch Linux ARM with a few mining apps thrown in. Then all you need is a Bitcoin wallet and a little bit of time. Given that you’ll be mining at a maximum of 330MH/s, you probably will be seeing pennies a day, if that. If you’re absolutely new to Bitcoin, you can learn a bit more about how to set up all the accounts and wallets here. I think the real point, however, is the novelty of the kit.

It’s cool to see this little rig running and I think the wee USB-powered fan on top of it is the crowning touch. Put a couple dozen of these in a room and you could probably really do some damage and your farm will look sort of like Pikmin, which is a bonus.

Once again, World of Concrete magazine is looking to award the most innovative products in the masonry and concrete industries. If you’ve been tinkering in the construction field, it may be time to shine!

When was the last time you thought about crayons? More specifically, when was the last time you bought over 100,000 of them in order to make a sculpture? The answer is probably never, unless you’re Herb Williams. He is the Cezanne of Crayon, the Calder of Crayola, and his playful works often hold many more shades of meaning and depth than meet the eye.
