STM32 E22900T22D LoRa Transceiver Module and Range Test
Useful Electronics Mar 31,2023
https://youtu.be/fPgSf5HOfO8In this tutorial, two STM32 micro-controllers are exchanging data wirelessly over LoRa using E22900T22D module that is interfaced over UART. The MCUs are exchanging dummy data to toggle onboard LED as an indication for ongoing wireless communication. Outdoor wireless mid-range (around 1000m) communication test was also conducted where no packet loss over LoRa was observed. E22900T22D Module which uses SX1262, parameters configuration, its interface packets are discuss...

CH340C programmer with Auto-Reset
M Mar 10,2023
Sometimes, your ESP based project doesn't need a dedicated USB to TTL chip because you won't upload the firmware so often (especially on custom / embedded projects).In this case you can use a dedicated USB to TTL module, to help you upload the firmware.But as you know, sometimes ESP chips needs to have certain pins tied to GND in order to enter boot mode, so you have to either add a button to do that, place some solder pads and use a tweezer to short those pins or some other methods.To be honest...

DIY Advanced Plasma Rife Machine
Pavleski Mar 10,2023
 Royal Raymond Rife was a scientist, inventor and medical researcher (1888-1971). He is known for his microscopes, which he claimed could observe live microorganisms but also by an electronic device constructed by him called the Rife Machine, which according to his claims, is capable of curing very serious and incurable diseases. In order not to repeat myself, if you are interested in the method of operation, making, technical characteristics, the way it is claimed to heal and many oth...

ESP32S3 GC9A01 LVGL Smart Watch
Useful Electronics Mar 10,2023
https://youtu.be/Td08fweKXwYIn this tutorial, ESP32S3 MCU is used to display time and temperature data on a round display with a nice looking user interface that is designed using LVGL library with the help of Squareline Studio.SNTP is used in order to get real time data over TCP connection with WiFi. The MCU processes the data and prints it on the GC9A01 display that is interfaced over SPI protocol.Temperature data, on the other hand, is obtained over MQTT connection with Node-Red that is runni...
