$6.5 RAK11160 LoRaWAN, WiFi, and BLE module pairs ESP32-C2 with STM32WLE5 for low-power, long-range IoT

RAKwireless RAK11160 is a new low-cost, low-power LoRaWAN, WiFi 4, and Bluetooth LE module based on ESP32-C2 (ESP8684) wireless microcontroller and STM32WLE5 LoRa SoC for LPWAN IoT applications. The company noticed that many people would combine their STMicro STM32WL-based RAK3172 WisDuo LoRaWAN module with an ESP32 module to add WiFi and/or Bluetooth connectivity to their projects besides LoRaWAN. So RAKwireless decided to offer a module combining both STM32WL and ESP32-C2 to offer a cheap and much more compact solution to their customers. RAK1160 was born.

Map Remote ID-enabled drones with ESP32-C3/S3 and Meshtastic LoRa modules

Colonel Panic’s Mesh Mapper is a project designed to map drones emitting the FAA’s Remote ID over WiFi or Bluetooth with location, altitude, pilot position, and identification data. This project utilizes an ESP32-C3 or ESP32-S3 to capture Remote ID transmissions within range, and then feeds the data into a Python Flask web application part of Mesh Mapper that provides real-time visualization and logging. Meshtastic allows multiple detection nodes to share information across a mesh network, so several ESP32 nodes can be deployed in an area and be alerted when drones fly within your property or neighborhood. While you could use your own ESP32-C3/S3 board and Meshtastic hardware for this project, Colonel Panic designed a breakout board for XIAO ESP32C3 or ESP32S3 WiFi & Bluetooth module and Heltec LoRa 32 V3 connected over serial to make things easier. Something like the XIAO ESP32S3 for Meshtastic & LoRa devkit might also do, […]

$24 Lucky Miner SOLO-LV02 is the equivalent a lottery ticket for Bitcoin mining

Bitcoin mining now requires expensive machines, so I was surprised when I saw the Lucky Miner SOLO-LV02 cryptocurrency mining “machine” going for about $24 on AliExpress (link at the end of this post). The USB-powered box is capable of mining coins with the SHA-256 algorithm, and features a 1.9-inch display, WiFi connectivity, and two buttons. In theory, we’re told the device can mine BTC, BCH, BSV, DGB… Considering the really low hashrate, it’s the equivalent of a lottery ticket for Bitcoin or other cryptocurrencies, and the luckiest ones may get one Bitcoin block (3.125 BTC).
