Flying Bear Ghost 5 simple spacer for dual drive extruder
I have a little problem with my Flying Bear Ghost 5; the filament does friction on the filament sensor because it changes angle when extruded, so I added a simple spacer to fix this.

GY-291 ADXL345 i2c spi accelerometer with interrupt for esp32, esp8266, stm32 and Arduino
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. This device works with i2c and SPI protocol and Is suitable with Arduino, esp8266, stm32, and esp32.
STM32: ethernet enc28j60 with plain (HTTP) and SSL (HTTPS)
We already saw the w5500 devices to make a wired connection with STM32; now, we will examine enc28j60, a cheaper device with few resources but relatively stable and widely diffused. We also try to add SSL for a secure connection.
Arduino: fast external SPI Flash memory
For devices like Arduino UNO, we can use the SPI Flash with a basic and very light library, but It can manage a good quantity of memory (from 256Kb to 64Mb), and it’s enough for a lot of projects.
ESP32-CAM: control CameraWebServer from your own web page – 3
I’m going to write this simple article because I started using this device as an “external IP cam” for my web project, and I’d like to share my experiences.
ESP32 WeMos LOLIN32 EByte LoRa E32, E22 and E220 shield
I’m going to publish my LoRa shield for WeMos LOLIN32. This is one of my favorite microcontrollers, and until now, I have been using a simplified version of shield for rapid prototyping, but in the end, I created a more complete version, and I share it with everyone.
STM32: ethernet w5500 with plain (HTTP) and SSL (HTTPS)
When I started using the STM32 I discovered a world. they are powerful with a lot of features, but they have lacks a network connection. This can be resolved with a w5500 module, a quite powerful device that allows a wired connection.
LoRa remote water level and pump controller (ReWaL): assemble client and 3D printed case – 7
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify to the server.
Now we put all the Client components in the relative Case.
Black Pill STM32F4: pinout, specs, and Arduino IDE configuration – 4
This article will explain how to program the Black Pill STM32F4 microcontroller board. It can be considered the big brother of the STM32F1 series, more powerful, and with all the features of the F1 version.
LoRa remote water level and pump controller (ReWaL): assemble server and 3D printed case – 6
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify to the server.
Now we put all the Server components in the relative Case.
