Tele Servo Bender emulates a lap steel sound using servos

Though mostly associated with country music, there's a pretty good chance that you've heard the sweet singing tones of a lap steel guitar in whatever modern genre floats your boat.

Rather than gently stroke the six to ten high action strings of an electric lap steel with a glass or metal bar though, Dean Miller opted to recreate the sound using four servos controlled by a modified foot pedal array and an Arduino running some custom code. The result is pretty astounding.Read More

The linear drive not only creates a more relaxed seating position, it offers some claimed efficiency advantages, too.Read More

Linux software engineer builds his own PiPhone

Since its launch and slightly delayed shipping in 2012, we've seen Raspberry Pi computers used for everything from a bartender to robots to a bizarre musical instrument. Now dedicated tinkerer Dave Hunt has used a Model B to create a touchscreen smartphone called the PiPhone, though he readily admits that it would be easier and cheaper to pick up an (arguably much better looking) budget cellphone from a shop in the mall, "but hey, where’s the fun in that."Read More
