Bangle JS opensource hackable programmable smart watch

If you are searching for a smartwatch that can easily be customized and is completely open-source then you may be interested in the new Bangle.js hackable smartwatch.

You can easily install new apps from the web or develop your own using JavaScript or a graphical programming language (Blockly). All you need is a Web Browser (Chrome, Edge or Opera) and you can upload apps or write code to run on your watch wirelessly! Bangle.js is waterproof and AI-enabled and comes with Bluetooth low energy, GPS, a heart rate monitor, accelerometer and more.

Why JavaScript?

Developing software for embedded devices can be a real pain. You normally need wires attached to the device you’re developing for, and you need to install and set up a complex toolchain. Anything more than a few lines of code can take a minute or more to compile and upload to the chip, and this applies to every change you make. Many tools don’t even allow for debugging.

Bangle.js has none of those problems. The Espruino JavaScript interpreter allows you to upload code and debug wirelessly out of the box using just a Web Browser, with no need to install software on your computer.

Tensorflow Lite AI

Tensorflow Lite for Microcontrollers is built into  Bangle.js’s firmware so you can run machine learning models wirelessly on your wrist! This allows you to detect gestures using the accelerometer. If you’re feeling adventurous you can customize the data you collect and create or update machine learning models without even having to reboot your watch!

Simply train and test your model on your PC with Tensorflow, then create a tflite model and upload it to your watch.

Open Source

Bangle.js uses the Open Source (MPLv2) Espruino JavaScript interpreter. All source code, tools, and documentation are provided under an Open Source license.
