      #Blog: From Pagekit to OctoberCMS

      Web designs | 1 min | 1381


      Just a small post. I've migrated the blog from Pagekit CMS to OctoberCMS. Pagekit was a nice CMS, but unfortunately the project is almost dead, so I've decided to migrate to OctoberCMS.

      Why I didn't choose Wordpress? Well, I hate Wordpress. I've tried a lot, but everytime I found that it was not for me.

      So, I have a ToDo for you: If you find something that it is not working, please use the contact formular or the comment section below to inform me! I've checked everything, but I've migrated almost 100 pages (articles, static pages etc.) and all the meta information and probably I forgot some...

      #Review: Meet the M5Stack FIRE

      m5stack fire

      This 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...

      #Raspberry Pi: CUPS Printer Server using Docker

      A good friend of mine has an old printer and he was always thinking of buying some adapter to make it Wi-Fi compatible. He actually bought one, but it was not compatible! I told him to buy a Raspberry Pi W Zero and build a CUPS Print Server, but he did not have time to do that, so I planned as XMas gift! I hope he is not going to read this before he gets his present. :) - If you received this as a gift, your instructions are here.

      A big challenge was to make it plug & play. I did not want to have his Wi-Fi credentials, and he should not use a terminal over SSH to configure it. I looked for som...

      #MicroPython: Home Automation using Blynk connected to a WiPy 3.0 / 2.0

      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...

      #MicroPython: Programming an ESP using Jupyter Notebook

      jupyter kernel
      visual studio code

      I was looking at my last articles about MicroPython and my new articles about Jupyter and Docker, and I thought if it is possible to make a mix between Jupyter and the ESP boards. I use usually Visual Studio Code to program the ESP but for analytics I use Jupyter. I looked if it was possible to connect the Jupyter kernel to the ESP using the serial port and: Yes!, it is possible. This can be a great tool to teach kids to access data from connected sensors and analyze it us...

      Out with the old, in with the new! Happy 2019!

      It's been a two years now since I started this blog. It's a hard job to maintain it up-to-date but I still have fun writing and coding for this purpose! I hope the next year will be better than this one! :)

      This post includes a new video for happy new year! The video combines some of the MicroPython code, that I've published this year. I'll be uploading the repo to GitHub in the next days. But, in the meantime enjoy the video, and check the MicroPython projects here!

      #Analytics: Portainer for Docker Management

      docker management

      Portainer is a management UI which allows you to easily manage your different Docker environments.

      This is what I will try to accomplish in this tutorial. You will be able to:

      • Run Portainer for Docker management on Windows, Linux and on a Cloud platform
      • Start container with a predefined admin password, in case you are on a public network

      Linux/Mac OSX

      If you are running Docker on Ubuntu or Mac OSX, you can start using Portainer as a Docker Container typing the following:

      docker volume create portainer_data
      docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:...

      Quoting the official MicroPython's website:

      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 optimised to run on microcontrollers and in constrained environments.

      Besides C++ and C, I use MicroPython to program microcontrollers, especially the ESP32/ESP8266 types. These two microcontrollers are compatible with MicroPython and it is easy to integrate sensors and actors programming using this language. I wrote a tutorial about installing MicroPython on the ESPs, as well a lot of articles a...

      merry Christmas

      LeMaRiva|tech wishes you a Merry Christmas and a Happy New Year! To celebrate I made a video using the Xmas-lights from last year, but this time I connected the ESP32 to a Jupyter kernel to control the lights. A new Jupyter-ESP32 tutorial is coming soon. In the meantime, you can track Santa and spend time with your family!
