Testing software is — sometimes — easier than testing hardware. After all, you can always create test files and even fake user input before monitoring outputs using common tools. Hardware though, is a bit different. Sometimes it is hard to visualize exactly what’s happening. [Andrew Ray’s] answer? Produce simulated waveforms …read more
For most of human history, musical instruments were strictly mechanical devices. The musician either plucked something, blew into or across something, or banged on something to produce the sounds the occasion called for. All musical instruments, the human voice included, worked by vibrating air more or less directly as a result of these mechanical manipulations.
But if one thing can be said of musicians at any point in history, it’s that they’ll use anything and everything to create just the right sound. The dawn of the electronic age presented opportunities galore for musicians by giving them new tools to create …read more

[Hunter Irving] has been busy with the Nintendo LABO’s piano for the Nintendo Switch. In particular he’s been very busy creating his own custom waveform cards, which greatly expands the capabilities of the hackable cardboard contraption. If this sounds familiar, it’s because we covered his original method of creating 3D printed waveform cards that are compatible with the piano, but he’s taken his work further since then. Not only has he created new and more complex cards by sampling instruments from Super Nintendo games, he’s even experimented with cards based on vowel sounds in an effort to see just how …read more

We’ll be honest: If you are a regular Hackaday reader, you probably won’t learn much new information about waveforms from this website. However, the presentation is a great example of using React on a webpage and — who knows — you might just pick up something interesting. At the very least, it’ll be a great resource the next time you try to help someone starting out.
The animated waveform is cool enough. It is also interesting that it changes based on where you are in the text. The really interesting part though is that you can press the M key …read more
When it’s time to put together the annual Christmas card, most families take a few pictures of the kids, slap on a generic greeting, and call it a day. It used to be fairly common for the whole family to get dressed up and pose for a special Christmas picture, but who has the time anymore? It’s not like we have hours and hours to slave over a unique and memorable gift we can mail out to a dozen (or more) people.
Unless you’re [Chris Wolsey], anyway. Rather than take the easy way out and simply mailing some pictures of …read more
In need of a waveform generator for another project, [David Cook] crammed out the old turntable to modify it for a handy hack: By adding a simple reflectance sensor to the pickup he turned it into a waveform generator that optically plays back arbitrary waveforms from printed paper discs.
For his hack, [Dave] created a 3D printed mount, which attaches a LED and a photodiode to the pickup of the turntable. The mount also blocks most of the ambient light, allowing only the reflected light from the paper disc to reach the sensor through a small slit. A little breadboard …read more
