Check out this cool home brewed iPhone Voice Recorder. Tight.

My iPhone broke. The screen just died a slow death, getting brighter and brighter and then very hot and then…nothing…over the course of a morning. With no phone to play with this morning, I did a lot of thinking and hunting through iPhone foundation files instead. And I seemed to find quite a lot of interesting calls in the Celestial framework, specifically the AVRecorder class.

Yep, you CAN make a hovercraft during your lunch break now. Just follow the directions!

I built a working hovercraft using cardboard and a shop vacuum in 30 minutes.

You can build a hovercraft quickly and easily using cardboard, duct tape, and a vacuum. There are excellent instructions available on the Internet. I adapted these standard instructions by substituting cardboard for plywood. In fact you build a hovercraft out of most anything that’s more or less airtight.

You can ride your hovercraft outside by using a gas powered leaf blower instead of a vacuum. Don’t use a leaf blower indoors because they are very loud and create smoke. One problem you will encounter outside is that there are few flat surfaces. Tennis courts work well. If you try to ride on the road you will quickly end up in the ditch since roads have a convex surface that keeps rainwater from building up.

Well… you CAN make an alarm system in 3 minutes too… (That means you can make 10 alarm systems for the time it takes to make 1 hovercraft…)

Wow, this is somethin’ I’ve always wanted to make with the free laser Dragonlasers sent me a long time ago…

But here it is! Looks like he’s from the UK.

P.S. Remember we ARE giving out a FREE Dragon Laser to the top commentator this month.  So make sure to participate.  Looks like Brian is going to get it at this rate.

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.
