WeMos D1 (esp8266) manage relay and shield
To help fast prototyping I’m going to create a set of shield for WeMos D1 mini, the shield manage a 3.3v relay with configurable pins
AWS IoT core and MQTT services: introduction and prerequisites – 1
It’s time to connect our device to AWS IoT core via MQTT services, in this tutorial I’d like to connect an esp32 an esp8266 and an Arduino MKT 1010 WiFi to these services.
Here a briefly introduction and I show all the prerequisite.

WeMos D1 (esp8266): i2c shield to manage encoder, multiple buttons, and LEDs
For fast prototyping, I will create a set of shields for the WeMos D1 mini; the first is a service board with integrated pcf8574 IC, an encoder, and five other pins to use as input or output.
bCNC Tutorial: restore work and milling process – 3
After carrying out all the calibrations, all that remains is milling our piece. If the whole process is successful, I expect an excellent final product.
bCNC Tutorial: autolevel – 2
One of the most important features is the auto-level. Even if your CNC is precise, it will never be accurate to one-hundredth of a millimeter, but to carry out the removal of copper, you will have to have an excellent level of precision.
Here we are going to learn how to do auto-level.
bCNC tutorial: installation, probe, PCB instruments – 1
I have been prototyping PCBs with the CNC for years. I have created a CNC machine suitable for this, and today I would not know how to do it without it.
I have been using bCNC for some time as a GCode sender, a very simple open-source software, we will see how to install it and do the probe.
esp8266 firmware and filesystem update with FTP client – 2
In this series of article about firmware and how to update It, I’d like to add a series of alternative methods of updating that are very useful for me.
In this article, we will learn how to add an FTP server to our device and use It to upload firmware and filesystem updates.
esp8266 firmware and filesystem update from SD card – 1
In this series of article about firmware and how to update It, I’d like to add a series of an alternative methods of updating very useful for me.
In this article, we will learn how to use external storage like the SD card to update firmware and filesystem.
