MechBass robot nails bass guitar sounds with Arduino and a stone cold groove (video)
End-of-year engineering school projects often pique our interest for their creativity. It's not every day that they can carry a bassline, however. James McVay's robot project for his honors year at the Victoria University of Wellington, the supremely well-named MechBass, wouldn't have much trouble keeping up with a favorite band. It centers on a custom, Arduino-compatible board that controls the plucking, fretting and damping of four strings to faithfully recreate bass guitar sounds from MIDI input. The design even accounts for the unwanted noises of actuators and motors, while virtually everything was either 3D-printed or laser-cut just for the task at hand. Sounds good? There's more in the pipeline: an upcoming Swivel robot will experiment with different playing techniques, and McVay ultimately sees his work teaching us about robotic music's interaction with human performers. For now, we'll be happy with the video after the break and hope that MechBass takes requests.
IBM cluster powers Murchison Widefield Array's radio telescope, answers mysteries of the universe faster than ever (video)
Radio telescope operators have as much of a problem coping with the avalanche of data as getting that information in the first place. The Victoria University of Wellington is all too aware and is leaning on IBM for a powerful (if very tongue-tying) iDataPlex dx360 M3 compute cluster to sift through the deluge at the upcoming Murchison Widefield Array. Combined, the 4,096 array antennas probing deep space and solar atmospherics will have the Xeon-based cluster tackling signal data to the tune of 8GB per second, and about 50TB per day -- that's a Nexus 7's worth of astronomy faster than you can sneeze, folks. A 10Gbps network connection will feed the results to Perth to save scientists a roughly 435-mile trek. Construction is still in mid-stride, but the $51 million Australian ($52.2 million US) being spent on the Murchison array may be worthwhile if it helps solve the riddles of star formation and solar flares.
