A user review of the Nerd Miner, a small device with minimal mining capabilities but allows users to participate in the BTC network.
A Flasher utility for DIY miners to flash NerdMiner firmware onto various boards, such as LILYGO S3 Dongle, LILYGO T-Display-AMOLED, ESP32-WROOM, LILYGO T-QT, TDisplay v1.14, ESP32-2432S028R, and M5-StampS3. The flashing process should take less than one minute.
Guide for setting up the NerdMiner, an educational bitcoin mining device powered by the LILYGO T-Display-S3 ESP32-S3 development board. Detailed steps for both educational and simple setup methods are provided.
Nerd Miners offers Bitcoin lottery miners with plug-and-play functionality for DIY enthusiasts.
This project demonstrates how to use the ESP32-CAM to capture an image of a vehicle's license plate, send it to a cloud server for recognition, and display the recognized number plate on an OLED screen. The project includes setup instructions, code, and component details.
Track Bitcoin prices automatically with an ESP32 and an OLED display using MicroPython or Arduino.
