3 min | 5641This tutorial helps you update a BRIO locomotive using an ESP32 that runs MicroPython. As a result, you can control the speed of the BRIO using a cell phone or a laptop (basically, everything that has a browser).
If you don't know what a BRIO locomotive is, check out the following picture:
Fig. 1: BRIO World 33594 In this tutorial, I will try to accomplish the following points:
- Hardware modifications on a ESP32 board;
- MicroPython installation;
- Controlling the locomot...

11 min | 26639This tutorial is about training (on PC) and deploying a YOLOv2 object detector on a MAix M1w Dock Suit running MicroPython. The MobileNet is used as a pre-trained model for the training.
Therefore, this tutorial will try to accomplish the following points:
- A quick introduction to YOLO(v2)
- A quick introduction to MAix KPU
- Training, evaluation, and testing of the object detector model (on Jupyter-Notebooks running on Docker)
- Flashing the trained model on the MAi...

1 min | 6438The following video summarizes the project highlights of 2019! Most of them are implemented using MicroPython on ESP32 and Python on Raspberry/Orange Pi.
The flying video was recorded with a Nexus 5X mounted on the Zhiyun Smooth 4. In the video-edition process, software stabilization was only used on the vertical axis. The Zhiyun Smooth 4 smoothed the horiz...

Dec - 2019M5Stack, MicroPython
4 min | 3656Holiday season has begun and Christmas and the New Year 2020 are approaching! This means, time to reflect and to clean up code and, therefore, I am updating some of the GitHub's projects to summarize the year. I started with the Christmas lights project! But, this time, I took the M5Stack Fire and a new LED panel (WS2812b - 16x16 pixel) and with the XMasLight project, these are the results (Fig. 1 & 2):

6 min | 76037Last year, I bought an ESP32-CAM board from Banggood and I wanted to use it with MicroPython. The board has an OV2640 without any chip (buffer) between the ESP32 and the camera. There are many implementation for Arduino or directly using Espressif, but I wanted to use MicroPython. Thus, the only solution was to use the I2S interface, but I didn't have time to write the driver. Thus, I put the project on hold. However, last week I was searching between the ESP32 boards that I have,...

4 min | 55031#MicroPython: VSCode IntelliSense, Autocompletion & Linting capabilities
MicroPython | 4 min | 55031
Last December, I wrote an article telling you that I was switching from Atom.io to Visual Studio Code to program MicroPython. Nowadays, I'm still using VSCode and the PyMakr extension. The latter enables the communication to a board running MicroPython using the built-in command line REPL. Thus, I can run a single file on my board, sync my entire project or directly type and execute commands using the Terminal on VSCode. However, I was missing some of the main features of VSCode, namely IntelliSense, autocompletion, and linting capabilities. Last month, BradenM contacted me and told me that he...

General, MicroPython | 1 min | 4258
This is a misc. small article. Two month ago, I bought on Banggood two articles that I wanted to show you, but this time, these are not connected to an application, code or a detailed product review. This is only a misc. article to describe my purchase: The Xiaomi Wowstick Screw Driver and the TTGO ESP32 WROVER with 8MB PSRAM.

5 min | 14666#MAiX Dock & MicroPython: Hands-On with low power AI at the edge
MicroPython, Product Reviews | 5 min | 14666
This week, I received from Seeed Studio a MAiX Dock to review it. The main board of the kit includes a Sipeed M1w which is a compact module like the ESP32 but based on the Kendryte K210 dual core RISC-V processor. It is designed for low power artificial intelligence workloads, such as face detection, object recognition, or audio processing. There are two type of modules: the Sipeed M1 and M1w, the last one includes WIFI connectivity.
The main features of the MAiX Dock boards are:
- Display I/F – A...

3 min | 8383This month, I received the M5Stack FIRE development kit with a PLC base kit from Banggood to review (see Fig. 1). After using it, I can affirm that the M5Stack takes an alternative approach to ESP32 prototyping, because the resulting projects are almost simultaneously finished products. This is possible because the board is housed in a stylish and robust hosing with graphics display, buttons, microSD card slot, USB-C port and speakers. I tested the M5Stack FIRE development kit, and the board i...

2 min | 10195#MicroPython: Home Automation using Blynk connected to a WiPy 3.0 / 2.0
Home Automation, MicroPython | 2 min | 10195
This time a quick tutorial to control your WiPy 3.0 / 2.0 or an ESP32 using Blynk.
Blynk is the most popular mobile app for the IOT. Works with anything: ESP8266, Arduino, Raspberry Pi, SparkFun and others.
I found a library to connect MicroPython to Blynk but it is only compatible with the WiPy 1.0. Thus, I modified it and made it compatible with the WiPy 3.0 / 2.0 and with the ESP32 running MicroPython. If you do not have any idea about MicroPython, I rec...
