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.
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 self OTA update in HTTPS (SSL/TLS) with trusted self signed certificate – 3
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi connection rather than a serial port.
In this article we are going to explain OTA update via HTTPS secure connection, and with a valid self signed certificate trusted from the client.

I bought an Alexa device and since then I don’t want to press a button anymore and I want to turn all my devices into voice control.
We have reached the last phase, now we have to go and test our smart home skill on a device, this must first be enabled and linked to your Amazon developer account.
esp8266 OTA update with Web Browser: sign the firmware and HTTPS (SSL/TLS) – 2
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi.
In this article we are going to explain OTA via Web Borwser of signed firmware and HTTPS with self signed certificate.
AWS Alexa Smart Home Skill: load sample code and test Lambda – 6
I bought an Alexa device and since then I don’t want to press a button anymore and I want to turn all my devices into voice control. So I start this tutorial to explain how to create a simple custom Smart Home Skill.
In this article we upload the Lambda sample code, it must first be packaged and then uploaded to AWS as a function code.
esp8266 OTA update with Web Browser: firmware, filesystem and authentication – 1
OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi. In this article we will explain how to make OTA updates via Web Browser, with and without basic authentication.
