Fresh hacks every day
[Chris] picked up a baby grand. Of course for a complex mechanical device made out of wood, it wasn’t in the best shape. He’s doing his best to refurbish this $350 piano and turn it into something that plays and sounds like a $200,000 concert grand
The 1941 Kimball baby grand piano [Chris] picked up for $350 was a complete … Read the rest
[Sebastian] wrote in to update us about the optical sensor project he started a couple of years ago. You’ll find his most recent update here, but there are four different post links after the break that document various parts of his progress.
You may not recall the original project, but he was looking to add resolution and sensitivity to … Read the rest
We love the look of this papercraft piano which [Catarina] built along with some friends at NYC Resistor, a hackerspace in the big apple. It starts off as a cubic black box with a white top. But just lift that top as [Catarina] does in the video after the break and three of the sides fall flat to reveal a … Read the rest
At Hack a Day, we don’t throw the term genius around lightly. We’re obligated to bestow that title on [Don Gilmore] for his amazingly simple self-tuning piano. To appreciate [Don]‘s build, you need to realize that just because a piano has 88 keys, that doesn’t mean it has 88 strings. Treble notes have three strings per key while tenor … Read the rest
Sometimes you just don’t have space for a baby grand. [Abdullah] got around this problem and built a virtual wireless MIDI piano. Unlike it’s inspiration, it’s not bad but we still love it.
[Abdullah] got his hands on some flex sensors and attached them to a glove. These resistive sensors are put through a voltage divider and sent … Read the rest
[Todd Harrison] recently wrote in to tip us off on his submission to the Tektronix oscilloscope contest – using a scope to tune a piano. In his video he demonstrates how a Fast Fourier Transform can be used to determine the fundamental frequency of the note being played. This is a quick and easy way to determine if that … Read the rest
[Joren] likes his digital piano, but it was missing one key component that he wanted to use: the ability to produce vibrato while playing. Vibrato can be done in several different ways on regular pianos, but it seemed as if there was not a lot of consideration given to the effect when designing digital pianos.
He enjoys playing all sorts … Read the rest
