Don’t Forget Your Mints When Using This Synthesizer

While synthesizers in the music world are incredibly common, they’re not all keyboard-based instruments as you might be imagining. Especially if you’re trying to get a specific feel or sound from a synthesizer in order to mimic a real instrument, there might be a better style synth that you can use. One of these types is the breath controller, a synthesizer specifically built to mimic the sound of wind instruments using the actual breath from a physical person. Available breath controllers can be pricey, though, so [Andrey] built his own.

To build the synthesizer, [Andrey] used a melodica hose and mouthpiece connected to a pressure sensor. He then built a condenser circuit on a custom Arduino shield and plugged it all into an Arduino Mega (although he notes that this is a bit of overkill). From there, the Arduino needed to be programmed to act as a MIDI device and to interact with the pressure sensor, and he was well on his way to a wind instrument synthesizer.

The beauty of synthesizers is not just in their ability to match the look and sound of existing instruments but to do things beyond the realm of traditional instruments as well, sometimes for a greatly reduced price point.

IoT for Ninjas – microcontrollers and sensors meet martial arts training


Carlos Justiniano writes on Hackernoon:

In this post we’ll build a DIY device to transform a Japanese Katana into a smart fitness device. Say what? Stay with me… the first part of this post will address the why for doing this, while the second part focuses on the how.

What if one could take a practice sword and retrofit it with sensors to track the quality of motion? And what if one could build a mobile application to analyze that data in realtime? While we’re seeing rapid advancements in AI — a Siri-like trainer is still some time away. And we’re even further away from replacing a human Sensei. However, since science fiction has a way of becoming science fact, it isn’t difficult for one to imagine a Jedi knight training sword, complete with holographic Sensei.

The build uses an Adafruit Feather Bluefruit 32u4 Microcontroller, battery, and the Adafruit LSM9DS1 9 degrees of freedom motion sensor.

Help bring CircuitPython messaging to other languages! #CircuitPython


blinka computer

One of the exciting features of CircuitPython 4.x is translated control and error messages. Native language messages will help non-native English speakers understand what is happening in CircuitPython even though the Python keywords and APIs will still be in English. We were inspired by the awesome translation work done in mu 1.0.0. (They even discussed the benefit translating error messages.) We saw this and loved the idea of both mu and CircuitPython being in one’s native language.

So, we’ve added the mechanics to CircuitPython that allow us to translate strings at build time. However, that’s not enough! We’re asking folks for help in translating messages to other languages. Carlos, @C47KD, was kind enough to help with the Spanish translation (seen below) and Pierrick, @arofarn, volunteered to do French.

If you would like to help, then please post to the main issue on GitHub and join us on Discord. Thanks!
