Wow, this is an awesome instructables on how to make an LED Hoola Hoop!

Some friends wanted a lighted hula hoop for burningman, and when they turned out to be about $200 each, I decided to make one. All the parts cost about $15 . . . total time to make the hoop was about 3 hours, but that included time for figuring things out. You could probably make one in less than 2 hours with this instructable and soldering skills . . .

Wow, check out how to make HOT ICE! This is awesome if you have some sodium acetate laying around.

A heat pack like the one you are describing contains sodium acetate and water. It turns out that sodium acetate is very good at supercooling. It “freezes” at 130 degrees F (54 degrees C), but it is happy to exist as a liquid at a much lower temperature and is extremely stable. Clicking the disk, however, has the ability to force a few molecules to flip to the solid state, and the rest of the liquid then rushes to solidify as well. The temperature of the solidifying liquid jumps up to 130 degrees F in the process.

As far as tools go you can never mess around with measurements, when locating power cables and water pipes etc.

- Locates concealed AC power cables
- Locates concealed metal objects like pipes, nails, screws, cables etc
- Incorporates a Laser Level
- Incorporates a Spirit Level
- Incorporates a ‘white-light’ LED Torch
- Tests Light Bulbs including fluorescent and incandescent bulbs/tubes
- Tests Cartridge Fuses, Diodes, Capacitors, Heating Elements etc
- Locates breaks in an AC power cable
- Checks polarity on two cable (no earth) AC appliances
- Incorporates a ‘self-test’ battery check for added safety and piece of mind

This is an ideal tool for home, especially if you have new home and are not quite sure where everything is.

Check out this cool Multi-Touch Multimedia device. This could be a cool combination of touch, sound, and video for future video game controls.

MultiTouch is the ability of an input controller to detect multiple fingers simultaneously. Multitouch input devices are just starting to be seen in the real world, rather than just in the movies (the most famous being “Minority Report”). MAKE magazine has even declared them the The Future of Interfaces.

For Maker Faire 2007, I propose to demonstrate a variety of graphical, musical, video, and browser-based applications that I’ve developed that show some of the unique capabilities of use of MultiTouch controllers. Below is a picture of the custom controller I’ve built containing 3 Fingerworks iGesture pads (each capable of detecting multiple fingers simultaneously with excellent resolution and responsiveness), and a JLCooper CS32 with lots of sliders and buttons for additional control.

It’s been a blast yet we’ve been able to get barely 5 hours sleep. But we will get all this cool stuff posted.

Mayhem & Chaos brings you some really cool sit and pedal POV (Persistence of Vision) using recycled bicycle parts.

I guess Mayhem took it to Burning Man every year. Cool… I gotta go one of these days.

Thanks Mayhem for letting us take a vid!

Check out these Cool ALAVs (Autonomous Light Vessels) by Jed Berk! Tight! It uses Sun Microsystems SunSpot microcontroller, which can be programmed in Java. I like this idea since there’s a lot of Java embedded processors out there but this ones from the creators. Jed tells me that all the pieces were 3D designed on the computer and laser-cut, kinda cool~

Jed says, Make Store will have these cool DIY ALAV kits soon!

Internet is kinda slow here at the Maker Faire. (That’s why our posts are slow too.) We even switched to a Sprint Broadband but with live video streaming, it’s still too slow but we will keep postin’~

You can come and join us to chat here to while watching our live video.

You can also check out our Flickr photos from Maker Faire Day 1 and Jed’s Flickr for more ALAVs.
