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 [...]

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 [...]

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 [...]

[Sebastian Steppeler] has been hard at work on his optical sensors for an electric piano. When we looked in on the project back in October he was testing reflective sensors to increase responsiveness and MIDI data resolution for his electric keyboard. Since then he’s finalized the sensor circuits and produced enough boards to monitor all [...]

[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 [...]

What do you do with 100 player piano rolls but no player piano? You come up with a way to digitize the information for MIDI playback. The rolls have 90 columns worth of holes, 88 for the keys and two more for pedals. Voids in the paper cause a note or pedal to be played, [...]

[Sebastian] is trying to improve the responsiveness of an electric keyboard. He was unsatisfied with the lack of adequate sensitivity to keystroke. The first step in his process was to measure how fast the quickest keystroke actually is. By setting up an LED and phototransistor and taking some measurements he found that sampling at 1 [...]

[Diego Stocco] makes music with instruments he assembled. For instance, his Bassoforte uses piano keys, the neck and strings from an electric bass, and what look like some cymbals. Throw in a hammer from that piano and a double bass bow (plus heavy use of audio software) and he’s in business. Big business actually, his [...]

The MIDI piano instructor is a tool aimed at those who wish to learn to play piano, but don’t want to take lessons. The LED bar mounted above the keys lights up to show you exactly what key to press and when. We’ve seen this available in some electronic keyboards for some time, but this [...]

We always wondered what happens to ancient pianos when the internals can no longer be kept in a playable condition. [Jean Philippe Roch] gutted his elderly upright and fit a Korg Triton inside. After the break you can watch a few videos including a slide show of the work log.  [Jean] separates the Korg keyboard [...]
