When we introduced you to the Twitter Christmas tree ornaments, sadly we had very little information about the project. Luckily [Rob] made contact and clued us in on the inner workings. It even turns out we were wrong about the usage of Arduinos! We invite you to check out all the juicy inner workings after the break.

[Joseph] wrote in to tell us about his Ikea Dioder hack. The Dioder is a lighting system with a silly name from Ikea. It is basically 4 RGB LED bars that are connected to a controller that will cycle their colors in different manners. They aren’t individually addressable, and at $50 aren’t really that great of a deal for people who could build their own. [Joseph] thought that maybe, if the features could be extended, it could be a decent lighting system. He bought it and began searching. Disappointed by the lack of hacks available, he cracked it open and began brainstorming. Ultimately, he decided to interface it with his computer. He can now control it with software, so making an ambilight clone shouldn’t be too difficult.
He does mention that he thought of making 4 independent drivers so that each light bar could be a different color. We agree that this would be the next logical step, possibly even rewiring for individual access to each LED.
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.
[Mike] covers his car whenever he puts it into the garage because the top is always open. After years of this ritual he decided to upgrade his garage to automatically cover the vehicle (link dead, try the Internet Archive version). The car cover, made from a few bed sheets, attaches to the bottom of the garage door. At the front of the stall the cover has two half-pound weights sewn in with plenty of padding to protect the car’s finish. Ropes attach to these weights, travel through a pulley system, and connect to the garage door opener carriage. This $65 dollar solution makes sure [Mike’s] car is always taken care of.

[Lucas] is at it again this year. Not satisfied by the computerized systems available on the market, [Lucas] decided to build on last year’s project. To save a bit of cash, he built the setup around Parallax’s low-cost SX28 proto board. The system is capable of controlling 102 channels, with 8-bit dimming. 6 boards control 7 channels each and are communicated to through a serial protocol (reducing the whole setup to only 36 feet of wiring).
More importantly, he’s teamed up with 3 other neighbors who also share a passion for outdoor Christmas lighting and they’ve put together the Christmas Tour of Lights. Money raised from all donations goes directly to the St. Jude Children’s Reasearch Hospital in Memphis, Tennessee.
…well not quite, but Victorian-styled nonetheless.
In the same vein as his previous creation, [Jake] decided to steampunk his new monitor. However, this time around, he managed to squeeze a full pc into the retro case. A custom aluminum chassis had to be designed and safely house the disk drives and motherboard behind the monitor. Since the 350W PSU was a bit too clunky to mount behind the screen, [Jake] rebuilt the base of the unit around it. The P4, 250GB SATA hard drive, and gold painted cooling fan allow the machine to run Kubuntu “Gusty Gibbon” smoothly. Coupled with a typewriter-inspired keyboard, [Jake’s] got a cutting edge antique setup.
[Willem] has been using an Arduino to monitor temperatures and electricity usage. For the temperature monitoring he picked up some 1-wire temperature sensors similar to those we’ve featured in the past. To pick up on electricity usage he’s not using an amp sensors, but because he’s in the UK he does have a flashing LED on his power meter. There’s a known trick to pick up these flashes with a photo cell to calculate energy usage based on meter readings. Finally, the data from the three sensors (indoor temp, outdoor temp, and energy usage) is piped over the Internet via an Ethernet shield so that it can be collected and graphed.
[Willem] has had the system running for a year. If you’re nosy you can look at the temperature graph generated from his collected data.
