Golf Club POV

"So we were thinking about how we could have a POV while making it useful. Well since people like to hit up the driving range or the golf course at times, we figured we could just make a POV out of a golf club. At the same time, we can make it kinda useful too.

As you can see, the letters will go backwards on the back swing and forwards on the forward swing. Ben Hogan’s “Five Lessons” has a good picture of correct swing arc for a golf swing."

If you already have a golf club than the whole projects will cost you about $74.00.

Floating Light Bulb

While many people will think that this was Photoshoped or edited in some way, it wasn't. The lightbulb is held in the air by an electromagnet that keeps the magnets that are hidden inside of the lightbulb about 2.5 inches from the nearest object and is powered wirelessly by a wireless transmit coil.

The Geek Scooter

ThoughtLab has taken a new Vino scooter and decided to make it into the ultimate geek machine. "The end result was a rolling system capable of long distance war driving, GPS navigation, Skype calls on the road and the ability to record TV programs so you don’t miss Lost because you are lost."
Their website has some great instruction on how they did this project and many more pictures.

Homemade RC Airsoft Turret

Invent Geek has built their very own remote controlled airsoft turret that it made using parts salvaged from an old airsoft gun, some servos, plexiglass, and some hardware. It shoots 1500 rounds per minute and can hold tens of thousands of bb's. Their website has step-by-step instructions but don't plan on making one unless you have about $200.00 to burn. Below you can see the turret in action.

Self Balancing Table

At the Retis Laboratory of Scuola Superiore Sant'Anna a team of engineers and DIYer's built a table that automatically tilts to make a ball stay on it even when the ball is pushed or dropped. The team uses a touch screen to locate the position of the ball and two servo motors to adjust the table. See the video below to watch the table in action. See their website for more details.

LED Hard Drive Clock

Ian has made an LED hard drive clock by using flashing LED's and a spinning CD with a slit in it to create patterns. He uses an LED strip from Super Bright LED's and programed the whole thing himself. The CD spins at 90 RPM which tricks the human eyes into thinking that it isn't flashing which is the reason that we see solid patterns. The thing, as you can hear from the video, is pretty loud, but later on Ian plans on building a plexiglass case to enclose the project to reduce the sound levels.

Weed Wacker Blender

If you think that you have a nice blender you may want to rethink that. Brett decided that he'd try to find a use for his old weed wacker engine from when he was a kid and he sure did! He took the engine and used it to power a blender, but that's not all. He is a huge drag racing fan and created his own miniature starting lights (christmas tree) as well as a nice looking RPM gauge and a cool trigger to power the speed as well as a cool LCD display. His favorite part.... The fact that he gets crouds to walk away from the drag race just to see his blender.

Ferris Bueller's Day Off Intercom Prank

Matt Meerian decided that he wanted to try to build a near replica of the intercom the Ferris Bueller used to try to fool his teacher into thinking that he was sick in the movie Ferris Bueller's Day Off. Matt searched on EBay for the same intercom that they used in the movie but, he couldn't find it so he just found an old intercom that looked like it had been outside for a while. He uses a Vinculum VMusic2 MP3 player as the main hardware for the intercom. The Vinculum VMusic2 MP3 player allows him to just plug in a thumbdrive into it and allows for the easy ability to jump from one sound file to another. If you are interested in building one of these intercoms for yourself or if you just want to see more information regarding how to build it visit Matt's website.
