Cloud Mirror is an interactive art installation that combines you and your easily available online information in real time. Attendees stood in front of the camera and held up their badges. Cloud Mirror then projected them on the wall and displayed a speech bubble containing information from the web. In the example after the break, you can see our very own [Eliot] displayed with his most recent twitter post. To add another layer to it, you could send a text message with someone’s badge ID to the system and it will display your message in that person’s bubble.

Going Green, By Not Buying New Stuff

Recycling is great. We’ve seen a pretty hard push in that direction recently. We like the fact that our modifying of hardware is generally saving it from the dump. Keep in mind, that just using old hardware can be advantageous too. We don’t always need the new shiny thing, maybe we’re fine with what we’ve got. That is exactly what lastyearsmodel.org is about. You can join their facebook group and even get stickers for your old devices.

Uses For Magnets

Sometimes we forget just how useful magnets can be. Sure, we use them in some projects, but usually we just pull them apart for our amusement. Evil mad scientist laboratories reminds us that they can be useful tools. They’ve made a list of 17 uses of magnets. We’re also reminded that magnets can be dangerous. What else can you think of?

Phillips AmbX Dissected

Electrosthetics has taken it upon themselves to open up and explore the insides of a Phillips AmbX system. The unit is supposed to help immerse you in your video games by adding ambient lighting, vibration, and wind. They got the starter kit, which is missing some bits. Interestingly they found that the hardware was not hampered in any way. You could plug in fans and such and, in theory, build the larger kit. There are lots of pics of the various pieces for you to look at. They note that the hardware all seems decent, but it’s the software that really causes issue. On their Vista64 dual core machine, the software was eating up an entire core to do ambient lighting.

Making Cool Looking PCBs

[Mike] has posted an instructable on making cool looking PCBs. He does it a little differently than we do. He uses soda cans for the stencils and combines the solder mas and silk screen steps. Also, a bit of extra cooking gives him this cool gradient of color. He has managed to get some really fine etching. It isn’t as fine as a laser etching, but this should be able to handle the smallest stuff you can throw at it. We’re a bit curious what exactly he’s building. There’s a color picture after the break to show you what we mean.

Twitter Brain Interface

April 20, 2009 by Eliot 36 Comments

Just in time for the influx of sedentary Oprah viewers, [Adam Wilson] built a brain interface that allows you to post Twitter messages. The electrode cap monitors the user’s brain functions to determine where they’re looking. The display slowly flashes each letter in the alphabet. The user focuses on the letter they want and when it flashes the cap can pick up the resulting impulse. It’s a long process and the average user can only do ten characters a minute i.e. 14 minutes to use all 140 characters in a Twitter post. It’s interesting research and shows how far we still need to go with neural interfaces. The researchers note that Twitter’s forced brevity levels the playing field between locked-in patients and normal users. A video of the device in use is available on the NITRO blog.

FIELD A Fluorescent Array, Wirelessly Powered

What would you do if you were driving along the highway and you glanced into a field to see a giant array of fluorescent tubes lit wirelessly from the electromagnetic fields of power lines. Back in 2004, [Richard Box] set up this display after hearing about a friend playing “light saber” with fluorescent tubes under power lines. The tubes can be lit pretty easily by have a variation in voltage between the ends. By sticking one end in the ground and the other up in the air, he’s harnessing the strong magnetic field from the power lines. Though some thought the display was made to bring people’s attention to possible hazards of living near the lines, [Box] states that he did it just because it looked cool.
