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.

Check out the entire blog post for the build, code, and more.

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!

The hits in the Adafruit Learning System keep coming today with a new guide on Circuit Playground Express Automatic Sunglasses. These glasses sense the light around the wearer and either cover your eyes or turn on a light. Perfect for the beach and camping. The code is both in CircuitPython and Microsoft MakeCode, take your pick.

I don’t think you can cosplay Data from Googies without such a nifty gadget, updated for this century. Check it out today!
