Finally, a working hoverboard you can make yourself, Ep. 186

Hey guys. My name is Stephen Beacham and here's what's happening this week on CNet's Crave blog. Who needs a dentist these days when you have a smartphone and a tooth scanner. Okay, okay. You probably still need a dentist but this tooth scanner device can sure make you feel like a sci-fi [INAUDIBLE]. Tooth scanner uses spectroscopy to scan your teeth for cavities. The device looks like a futuristic toothbrush, but instead of bristles it contains a pulse of light that bounces off the enamel of your teeth, relaying information back to the scanner. That data is then relayed to an app on your smart phone that can evaluate the health of your teeth. Spectroscopy is the process of evaluating the different colors. And a beam of light to determine certain information. In this case, according to the product video, when a light beam reflects from a healthy tooth, it has a distinct spectrum. When the beam reflects from a problematic area, there will be a spectrum deviation indicating poor health in your tooth. The overall idea is that if you monitor your teeth regularly, you will know whe- Concentrate brushing in places you may not be brushing properly, which may help improve the overall health of your teeth. You can pre-order your own tooth scanner on IndieGogo for $149. Since the Star Wars trailer came out recently, the Internet has gone bonkers with trailer candy, art. Work in 3-D printed toys made for a movie that has not even yet been released. Like some challenging folks at the Maker organization, like Fab Shop, have put together detailed instructions and uploaded a downloadable file to Instructables for 3-D printing your own customizable cross guard light saber. But, it's been the topic of some controversy. Amongst Star Wars super fans. [NOISE] The candy makers over at Le Fab shop watched the trailer, studied the controversy over the new lightsaber configuration and decided the best way to test the design was to make one. [MUSIC] The specs for 3-D printing your own lightsaber currently available for download at Thingiverse.com. So if you have a 3-D printer go and get it. [MUSIC] Dude, 3-D printers are so cool. While you're printing out your new lightsaber why don't you head over to 3DPrint.com. And learn how to hack MIDI files that you can upload to your 3D printer to play music. I'm not kidding it's a thing and it works. Check it out. [MUSIC] 2014 will be known as the year of the hoverboard, well to me at least. We saw a few working hoverboard prototypes, but the problem is that if you want to purchase one of these hoverboards [NOISE] You're looking at a pretty hefty price tag. Well do-it-yourselfer and inventor Ryan Craven is trying to reverse that trend and has produced an affordable and relatively easy to build DIY hoverboard. [MUSIC] Using four leaf blowers he purchased on Amazon for $200, he built, essentially, a hovercraft on top of an old water ski he found on the side of the road. He used other household items like, a shower curtain, tape, and staples to build his first working prototype he is calling, Mr. Hoverboard. Craven has been testing the boards agility at local skate parks in Austin Texas. And is currently refining the next prototype to be quieter and with improved air flow. He wants it to be as quiet and as sneaky as a Prius Hybrid. [NOISE] If you'd like to build your own Mr. Hoverboard. Ryan Crave has thoughtfully posted instructions instructions on how to make your own hover craft, hover board at Mr.Hoverboard.com where he is also accepting donations from people who want to support the project, so go and check it out.
