X-mas Hack: 8-channel Musical Show

December 2, 2009 by Mike Szczys 22 Comments

We’ve been seeing them appear one house at a time over the last few weeks as Christmas lights are making their annual appearance. Some folks just throw a set of net-style lights on the bushes and call it good but that wouldn’t suit [Noel]. He’s outfitted his house with a show that includes music, 8 controllable light channels, and an Internet interface.

He’s used a plastic toolbox as an enclosure to house everything. Affixed to the base of the enclosure are eight solid state relays for the strings of lights. An Arduino is used to control the SSR switching, playback music through an FM transmitter, and to interface with the wireless bridge.

Rubberneckers can tune their radio to the broadcast frequency and log into the web interface to request their favorite tune or track Santa’s current location. The device even implements VU monitoring to sync the light show with the music. If you want more, watch the video after the break or check out his step-by-step instructions. The Arduino library sure makes the code pulling this all together pretty simple!

IPv6 To 1-wire Protocol Translator

December 2, 2009 by Mike Szczys 16 Comments

[Fli] assembled an AVR based system that can assign IPv6 addresses to 1-wire components. An AVR ATmega644 microcontroller is used in conjunction with an ENC28J60 ethernet controller chip. To get up and running with IPv6 on this meek hardware [Fli] ported the uIPv6 stack from the contiki project over to the AVR framework. Although he encountered some hardware snafus along the way, in the end he managed to get five sensors connected to the device, each with their own IP assigned using the stack’s alias capability.

This is great if you’re looking for a low-cost IPv6 solution. We’re not sure if there’s much demand for that, but it’s useful for that 1-wire home automation setup you’re considering.

Joystick Controlled Alarm Clock

December 1, 2009 by Caleb Kraft 13 Comments

While it may sound like a dirty joke, turning off the alarm clock with a wiggle of your joystick is entirely possible here. [Sean] was inspired by the light gun alarm clock featured in Make magazine a while back and decided to build something similar. Instead of going the light gun route, he chose to use a joystick. You set the time on the clock using the joystick and the fire button works as a snooze button. Though it currently doesn’t have a snooze-waggle feature, it could without too much effort.

[Sean]’s server is small. He notes in his comments that he can’t handle the traffic from us. This is why we had to find it our selves instead of him submitting it. Tsk Tsk. To help, we have included the few other pictures of his build after the break. If you really want to overload his poor little server, you’ll find the link to his site here, instead of at the beginning of the article.

Control Your Tree From Anywhere

December 1, 2009 by Jakob Griffith 22 Comments

We honestly never thought we would see an internet controlled Christmas tree before, sure maybe a remote controlled claw or online soccer robots, but a tree? Regardless, team [Schwippy] did just that. 5 separate sets of lights are connected to 5 individual x10 modules. The x10s are listening over the household’s AC lines for commands from a server in the other room, with its own x10. At about 12$ a module, the project can get expensive quick, totalling over 200$ for [Schwippy’s] setup. Just to control a tree, but anything to spread the holiday cheer, right?
[Thanks Yon]

Voice Controlled Lock? Almost…

If you watched the video before reading the article (like we did) and started shaking in your boots at a voice controlled lock system, prepare to be disappointed. His spoken commands are actually to his son to press the appropriate keys on a keypad off screen, the lock is not actually voice controlled.

But still, [Michael Krumpus’] door lock is pretty astounding. By using a torn apart CD drive he easily attains a nice fast and smooth linear motion to bolt and unbolt his door. It wont open his door like some locks we’ve seen, but it will probably be added sometime in the future…right alongside voice commands.

Cable Management For Pull-out Shelves

November 23, 2009 by Mike Szczys 25 Comments

Cable management is a headache for all, and if unmitigated it becomes a playground for cats. [kws103] posted a project a while ago that takes care of the messy wires for electronics on pull out shelving. Channel bracket is used to house the cables and has been articulated in three places to facilitate the movement of the sliding shelf. For an added touch an outlet was built into the surface to make it easy to unplug and remove the components if necessary. The hinges for articulation use aluminum base plates and rely on rivets as a pivot point, something that might need improvement if pulling the shelf in and out is a common occurence. Add this to the Ikea based solution we looked at in August and your days of electronic rats nests may be coming to an end.

Another Stationary Bike VR Rig

November 19, 2009 by Mike Szczys 10 Comments

[Shingo] shared his implementation of a stationary bike as a virtual reality interface. This is similar to the Google Street View setup we covered a week ago but goes a few steps further. They patched into the bike computer to pick up rotation of the bicycle wheel and added an accelerometer for directional control. This setup can navigate through Street View but the video after the break also details an interface with Google Earth and even the ability to navigate through Second Life, following your avatar as it bikes along with you. The use of a wearable display is far superior to something like the SurfShelf and really gives you a goal other than just some cold-weather exercise. So take this idea, patch it into a wearable computer and you’ve got the exercise setup worthy of the future world we’ve been promised.
