1/6 🧵 I'm building what might be the smallest #opensource #spectrometer with an easy to use UI! I call it a pocket spectrometer. Combining #M5StickC (~$20) with AS7341 sensor (~$16). My goal? A complete spectrometer that is barely larger than a sample cuvette itself.

Made an automated toothbrushing timer - using accelerometer and #machinelearning. Running on a #ESP32
#microcontroller - implemented in #MicroPython

Mechanical parts in #FreeCAD

How to detect activities in motion data on wearable devices? With emlearn-micropython it is now pretty easy! Using #machinelearning one primarily needs to collect a small labeled dataset (for which there are tools & instructions). See github.com/emlearn/emle...

Last year I presented about Machine Learning on Microcontrollers at #PyData Berlin. Talk is available at

emlearn-micropython is a #machinelearning and #digitalsignalprocessing library for #MicroPython. Program TinyML on microcontrollers using familiar #Python

Hello world. My name is Jon, I work on Machine Learning for embeded systems and sensor data. github.com/jonnor/ and jonnor.com

The video of my "MicroPython: The Best Bits!" talk from the recent PyCon AU is now online:

As usual, PyCon AU was a great conf, thanks to the organisers and all the attendees!
