Hackaday alum [Will O’Brien] cleaned up his messy breadboard with an RGB keylock Arduino shield. You may remember this two-part project from last year. It uses buttons backlit by an RGB LED to operate a door lock.
[Will] is still mulling over what type of kit options he will offer. We’re happy to see if the most important part, a laser-cut key bezel, will be available. This makes for a professional looking finish that made the original project difficult to replicate.

MIT is debuting their latest advancement in technology, a multitouch screen that also functions as a gestural interface. The multitouch aspect is nothing new, the team explains how traditional interfaces using LEDs or camera systems do work, but fail to recognize gestures off-screen.
Gestures are a relatively recent highlight with the introduction of projects like Natal or perspective tracking, but fail to work at closer distances to the screen. MIT has done what seems the impossible by combining and modifying the two to produce the first ever multitouch close proximity gestural display.
And to think, just a couple of months ago the same school was playing with pop-up books.

[drj113] wrote back to let us know his latest version of the infamous Word Clock, now in Arduino flavor. You may remember when we originally showed you the Word Clock back in September, while much hasn’t changed, he’s added and modified a few things to make it more user-friendly. Most notably is the use of Arduino instead of PIC, while some commentators will complain this as a waste of an Arduino, it is extending the project towards those who are less technically inclined. Other changes include a new case, dedicated time changing buttons, and blue LEDs (and who doesn’t love blue).
We would also like to give [Alex], one of our commentators, a shout out with is QlockTwo. Same Word Clock concept, but used acrylic, paper sheet, and stickers to produce a much smoother look.
Update: It would appear we’ve made a slight mistake, the original creator of the QlockTwo is actually [Ruud Burger], not [Alex]. Thanks [Ruud] for clearing that up.
Evil Mad Scientist Laboratories has just released a Bulbdial clock kit. This has come a long way since their first prototype, featuring three PCBs to carry the 72 charlieplexed LEDs. For accuracy they’ve included an optional header for a ChronoDot precision RTC.
With a great looking face and laser-cut acrylic case available, this may soon adorn our mantle. Time to write that letter to Santa…
Update: [Windell] of EvilMadScientist.com posted some video of the clock in action. We’ve embedded it after the break.

We really love this version of super mario brothers that [Brad] is putting together. It is played on an 8×8 RGB LED screen, powered by a pic microprocessor. There aren’t many details on the construction or code yet, but we expect he’ll publish it soon. We’re guessing it is very similar to his other 8×8 game system. If you really want to get a jump start, he has published some great tutorials on working with pic microprocessors.

[Satiagraha] let us know that Texas Instruments(TI) has given out a neat “LED Reference Design Cookbook” PDF. The document contains 17 some odd little projects featuring different TI ICs and ways of using them to control LEDs in things from backlights to torches to solar lanterns to advanced PWM control! Sure the document is biased towards using TI equipment, but that shouldn’t stop you from recreating, modifying, and generally just having fun with their designs in your own productions.
[NeZoomie] built an RGB mood lamp as his first electronics project. He certainly hit it out of the park with this one, ending up with a design so clean it could be a commercial product. The controller is an Arduino board (further proof that this is a fantastic entry-level platform) that interfaces with 8 RGB LEDs. He’s built an enclosure out of thick polypropylene that does a great job of diffusing the light and adding a stylish look. The control system features a rotary potentiometer from SparkFun and what he calls a tilt-potentiometer of his own design after drawing inspiration from Hack a Day.
Blinky things are fun and that’s why we see a lot of mood lamps around here. Take a look at the video after the break and if you’ve got the parts, give this one a try!
