WeMos D1 (esp8266): HardwareSerial shield for Ebyte E32 E22 E220 LoRa devices
To help with fast prototyping, I’m going to create a set of shields for the WeMos D1 mini. The shield of this article manages the EBYTE LoRa device (E22, E32 and E220) with HardwareSerial, already exists a variant with SoftwareSerial.
AWS IoT core and MQTT services: creating AWS thing with certificate and policy – 2
In this article, we’ll understand the security system used by Amazon, with a certificate, to connect our device via MQTT.
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.
