Together with the Corel USB accelerator, I programmed a YOLOv2 object detector, etc.
The CrowPi kit is magnificent and has everything you need to start playing with the Raspberry Pi. Furthermore, you get everything in a suitcase, that you can close and clean your "mess" in seconds. :)

It is a rainy day and you have a Raspberry Pi, which is running Raspberry OS (Raspbian), and you think: I can make a media center to watch some movies/series. You configure everything, and then you see something like the next picture, every time that you want to watch Amazon Prime, Netflix, etc. using the Chromium Web Browser:Update 2021.04.05: Installing the Widevine DRM package to the Raspberry Pi is a straightforward process, follow the instructions from this tutorial: Raspberry Pi: Amazon Prime, Netflix, Disney, Spotify - a DRM official solution

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...

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:
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 beautiful...
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! (...
This tutorial is about programming the M5Stack Atom using MicroPython to transfer data to a LoRaWAN gateway. The gateway is then connected to the "The Things Network" (TTN) to process the data.
Before you start reading, check out the video of this setup!
The M5Stack ATOM Matrix is the most compact development board in the M5Stack development kit series with a size of only 24 x 24 x 14 mm and a weight of 14 g.
- 6 GPIO (Dupont Pins)
- GROVE/4Pin PH2.0 interface
- 5 x ...
MicroPython has almost all the features of Python, and allows you to easily interact with microcontrollers and sensors, making them accessible to both beginners and experienced Python programmers.
If you are new to MicroPython, I quote the official MicroPython page for you:
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on microcontrollers and in "constrai...
Last month, I published a review of the DSO138. This time, I put together the WAVE2 (15801K) and I review it in this article. The WAVE2 is a 2-channel portable oscilloscope design by JYETech for a hobbyist. It has a resistive touch screen display, X-T (signal-time) / X-Y (signal-signal) plotting functionalities, memory (4 blocks), measurement functionalities (V -max, min, avr, pp, rms-, frequency, duty cycle), serial interface and can be powered using an external 5V source (micro ...

This is a tutorial to control and display widgets on an E-INK display using an ESP32. Three widgets are available:
- Weather: weather forecast obtained using the OpenWeatherMap API.
- News: news highlights obtained using the NewsApi API.
- Notes: notes that can be added using a web-server that runs on the ESP32.
The result can be seen in this video:
Thus, in this tutorial, I will try to achieve the following:
