Electronic, 3D printing and embedded programming
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.
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
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.
I want to modify the WiFi module firmware of my FlyingBear Ghost 5 to support the Web Socket protocol and I want to develop the web interface as well.
Here I’d like to explain what is the MKS WiFi module how to program and how to connect a device that can be used like WiFi module alternative.
In this article I would like to show my custom PCB for the Ciclop 3D scanner which is fully compatible with the original ZUM.
I’m going to use the esp32, and the first problem was how to put It on breadboard, so we are going to print an adapter, then I build a PCB to program.
When I went to use esp12 and esp07, and the first problem was how to put it on the breadboard, luckily I found an adapter developed by tweeto, and that was what I needed, but I would like to make it easier to use, so I redesigned it smaller and added some labels to identify the pins, than I create a PCB to use It as programming board.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In this chapter we are going to wake on radio the LoRa E32 and microcontroller and we show the ESP32 DEV KIT v1 shield created for this device.
I’d like to monitoring my ABB Aurora inverter. So with an WeMos D1 mini I create a centraline with web interface, notification and other.
Now a case where you can insert all the component to complete the work.
I’d like to monitoring my ABB Aurora inverter. So with an WeMos D1 mini I create a centraline with web interface, notification and other.
Now we must solder and assembly the free PCB that I create for this centraline.
