Last week, I've received a brand new M5Stack ATOM Echo parallel to the market launch (see Fig. 1). You might already know the M5Stack company. They make robust and open-source development kits with stackable modules. The kits allow you to make rapid and high-quality prototypes.

Today, the M5Stack launches the ATOM Echo. Check out this video, and see how it works with MicroPython:

As you may have noticed in my past videos, I've been using a self-made rotating platform to display the projects. In this article, I'll describe and present it to you. It is still in its baby step, and I need a case to put everything inside. However, the code is available. The microcontroller is an ESP32, which is connected to Wi-Fi and hosts a website to configure the angle, speed, and direction of rotation. The ESP32 is programmed using MicroPython. Check out the following video!...

I've never used my blog to criticize a company. But this time, I need to express my complete disappointment with Gearbest. The last days, I have had the worst shipping experience, and I do have extensively worked with companies in and outside of the EU. In a nutshell, I ordered a home appliance on Feb. 21, and I'm still waiting to receive it. They've extended the shipping deadline twice (each time for one month), and now the tracking number has expired.

I've just updated the LoRa/LoRaWAN repository for MicroPython and added a configuration that works on the M5Stack Fire using the LoRa868 Module. Therefore, this will help you connect the M5Stack Fire to the "The Things Network (TTN)"!

If you're new to MicroPython read this tutorial: Tutorial: Getting Started with MicroPython on ESP32, M5Stack, and ESP8266If you want to know more about the LoRaWAN and MicroPython, read this article: Tutorial: ESP32 running MicroPython sends data o...

This tutorial is about exporting data from Google Firestore to Google Data Studio to visualize it; or to import it on Google Colab to analyze it and train a machine learning model.

This is the third tutorial from the series "implementing real-time data pipelines - from generation to models" and the other tutorials are the following:

• MicroPython: GCP getting air-quality data from an M5Stack ATOM
• GCP: Implementing Re...

Last year, I bought a Timeular tracker and I've been using it the past months to check the time I spent on my activities and plan my days better. Furthermore, on work-from-home days, it's hard to track how many hours I work per day, and the tracker helps me a lot with this! Therefore, I still recommend it.

I also wrote an article about the tracker and the Timeular application: Timeular: Tracking your time using an Octahedron. Both work great on Windows, Mac OS, and Android....

Two weeks ago, I published a tutorial that explains how to connect an M5Stack running MicroPython to the Google Cloud Platform using the IoT Core, and I did mention that upcoming tutorials will examine the following topics:

• Collecting and synchronizing external data (weather from OpenWeatherMap) and other sensors -window/door status, sneezing detector-.
• Saving the data to a NoSQL database
• Displaying the obtained data on Google Data Studio.
• Tra...

Spring in Europe has already started, and many people are having allergy problems. Therefore, I thought of making a project to measure air quality and collect this data to train a model that can tell me, when is the best time to open my apartment windows to let some fresh air into the apartment and thus minimize possible allergy attacks and sneezing! Like almost everyone right now (thanks to COVID-19), I'm working from home and this beautifu...

As you may know, the Philips Hue Bridge v1 has support until April 30, 2020. This means, after April 30, 2020, no software updates will be made available and it will not connect to the online services. However, you can still control it locally via the "dedicated Philips Hue Bridge v1 app". Nevertheless, you have a device (connected to your network) that can be a "treasure" for hackers (MITM-Attacks), and the "dedicated Philips Hue Bridge v1 app" will disappear shortly! (...
