Engineer designs DIY bionic hand for boy he met in an elevator

It seems like hardly a month goes by without news reaching us of advances in the field of bionic hands. Unfortunately, however, these high-tech prostheses can be very costly to purchase, with prices ranging into the tens of thousands of dollars. This puts them out of reach of a large number of people, such as a boy that General Electric engineer Lyman Connor met last year. Connor proceeded to design and build a low-cost bionic hand in his home workshop, which he now hopes to make available to amputees-on-a-budget .... plus he hopes to get one to the boy, if only he can locate him.

oneTesla shrinks its singing Tesla coil kit to palm-friendly proportions

The folks who successfully crowdfunded a DIY singing Tesla coil kit last year have taken to Kickstarter again to bring a smaller version into production. Like its older and bigger brother, the tinyTesla shoots out bolts of artificial lightning while playing MIDI music using the electricity itself. It looks like that polyphonic MIDI version of Danger High Voltage by Electric Six might just come in handy after all. Read More

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. OK, maybe not techno or electronica, but certainly blues, rock, jazz and folk music. 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

HummingBoard is set to take a bite out of Raspberry Pi

Since shipping in 2012, Raspberry Pi boards have found themselves the brains of such diverse DIY projects as a mobile phone, a touchscreen computer or even a treat dispenser for the family dog. Now there are three new boys in town that promise faster processing, more system memory and more connectivity options. Yes indeed, SolidRun's new HummingBoard family has all the makings of a serious Pi killer. Read More

MaynoothBike uses linear fork pedals for comfier ride

Seeking to cross the relaxed-back comfort of a recumbent with a higher seating position, German engineer Christoph Lenz has innovated the MaynoothBike, named after his home in Maynooth, Ireland. In place of the usual bottom bracket-mounted crankset, the dual drivetrain is built into the fork. 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."
