eSleeper combines cats, Arduino and Twitter in an eMac shell (video)

If we had to imagine our dream DIY project chances are it would involve Arduino, Twitter and, of course, cats. How we'd combine those things we're not sure, but we'll admit to being big fans of Samuel Cox's eSleeper, which turns a hollowed-out eMac into a bed for his feline. Inside the shell is an Arduino Ethernet connected to an IR sensor, some LEDs and a sound shield. When the cat breaks the infrared beam it triggers the iconic Mac chime and turns on a series color-shifting LEDs for a little mood lighting. From there the clock starts ticking. When little Fluffy (Captain Whiskers? Matlock? Penny? Greg?) decides she's had enough napping and leaves the white plastic cocoon, tripping the IR sensor again, a random phrase is tweeted, along with the length of the cat's siesta. Check out the video after the break to see the eSleeper in all its adorable DIY glory.

Stradivarius violin recreated from CAT scan, 'sounds amazingly similar'

We've seen all kinds of crazy things being printed -- from bones to blood vessels -- and now you can add antique violins to that list. Music loving Radiologist Steven Sirr popped his into a CAT scanner to see what it was made of, then showed the results to a violin-making friend. Curiosity soon led them to scan everything from guitars to mandolins, so when the chance to take a peek inside a 307-year-old Stradivarius came up, how could they resist? 1000 scans later, the files were converted to 3D CAD format and another violin maker enlisted. Crucially, the images show the density of the wood all the way through, allowing a CNC machine to carve out copies of each section, with different woods used to match the differing densities. With all the parts in place and a lick of varnish, the replicas were complete. Sirr claims the copies sound "amazingly similar" to the original, but we are unsure if he plans to make it
