MakerBotWatch

If you didn’t get the geeky watch you wanted for Christmas you should consider building yourself a MakerBotWatch. The watch is an Arduino, using an ATmega328 microcontroller running the bootloader. The watch has two concentric circles of LEDs for minutes and hours. A vertical row of four LEDs adds in the additional resolution needed to get 60 minutes on the watch face.

The schematic and board layout are available from an SVN repository so you can make your own board. The device will go into production as a kit but currently the laser-cut bezel will not be part of it.

(Yet Another) Twitter This Controlling Arduino That

Christmas may be over, but we still have a couple of cool holiday related hacks for you. One being [Alpay’s] Twitter based interactive Christmas tree ornaments.

We tried to dig up some more information, but it thus far appears a laptop running Processing searches Twitter for specific Christmas related words (like 1337, that’s Christmas-y), sends a buffer to one of three Arduinos which in turn light up a specific ornament. You can check out a live stream here.

For those wanting a bit more information on Arduino and controlling holiday lights, check out [Alpay’s] GE health care version of Twitter lights, or our previous post on controlling Christmas trees, or you might even try [Michael’s] $10 Walmart light controller.

VFD Clock (ends The World)

We honestly thought [Jason’s] VFD clock was some form of new terrorist attack when we came across the RSS. Thank goodness our relations with Russia aren’t as MAD as they used to be.

The main components are an IV-18 VFD with a MAX6921 driver, which to an untrained ear do sound surprisingly threatening. However an Arduino settles our hearts down and assures us this only has as much potential as blinking a VFD. While the main code, schematics, and CAD aren’t available (open source coming to a theater near you soon) at the moment – you can check out [Jason’s] inspiration, the Ice Tube Clock, which runs many of the same components.

Enjoy a video of it in action after the break. We love the ‘countdown’ feature the most.

Replacement Refrigerator Controller

[Michael] got his hands on a refrigerator that he intended to store beer in but found that it ran constantly. Instead of buying a new thermostat he and his friend [Doug] set out to build an Arduino-based controller for the fridge.

The finished project will switch 240v so they’ve used a transformer to power the logic circuitry and a solid state relay to handle the load switching, with a Dallas 1820 for temperature data. Because the Arduino offers more capabilities than the average thermostat hack they also decided to tap into its potential by adding an Ethernet shield. We see the Arduino as a prototyping device and so do these folks. Once the bugs in their first PCB prototype are worked out the circuit will use the ATmega328 and do away with the Arduino.

Spreading Christmas Cheer W/ Auto Parts

The folks over at [Soup], a British marketing agency, thought up this cool project. It’s a set of handbells hooked up to an Arduino, actuated by central locking motors found in car doors. By the look of some pictures, there was also a Lego version. Songs written by users (through the online interface) are placed in the que of a server. Once it’s time for the song to be played, serproxy sends the Arduino an appropriate set of commands for ringing the bells in sequence. All of this happens in the [Soup] office while it is streaming live through a webcam.

We think that this is definitely a great way to use surplus auto parts. After all, not everyone can build helicopters.

It seems as though the bells are down for the moment, or the employees got a bit annoyed at hearing them constantly ring.

Open Source Artillery

[youtube=http://www.youtube.com/watch?v=zPm84nxa2dk]

Thanks to [Josh, Kyle, and Mike], it is now possible to wage (Nerf) war with an Arduino. The turret designed around it is capable of shooting 6 foam projectiles in close succession, between reloads. The faux weapon interfaces with a computer through the Arduino’s onboard serial link (via USB). Software on the PC sends commands to the Arduino, which then executes functions, such as panning, tilting, firing, and rotating the cylinder. The power for the firing itself comes from a 5 gal, 80 psi air compressor. The Java software on the host PC also does smarter things, like show streaming video from the turret’s webcam and even performs basic object tracking (with mixed success). All the code for building the brute is available on [Josh’s] website.

Atmolight Clone Of An Ambilight Clone

[Fun3] wasn’t satisfied with current methods for duplicating Philips Ambilight. He wanted a completely plug and play solution without soldering so he could expand upon it in the future. This meant Arduino, ShiftBright, and (it pains us to say this) pre-made cables. Some of you are cringing at the thought of no real ‘work’ being necessary, but remember, now this is much easier for your “I can’t change the VCRs clock” aunt to set up and enjoy. Plus it’s quick, easy, and most importantly – clean, something a lot of hackers have a problem with.
