I turned an ESP32 Bitcoin miner into a practical Pocket Admin Toolkit. After running for more than 100 days, my original Bitcoin mining experiment became something much more useful: a fully offline touchscreen toolkit for Linux, networking, and system administration. Everything runs directly on the ESP32. No Wi-Fi. No cloud. No accounts. No API keys. Just fast, offline tools that are always available. Features • CIDR & subnet calculator • Visual Linux chmod calculator • HTTP status code reference • Common network ports reference This is only version 1, and I already have ideas for many more features.

The generator allows you to create STL files for 3D printing a fully customizable electronic enclosure. By changing the parameters in the source file, you can adjust the enclosure’s properties and adapt it to the specific requirements of your DIY project. The parametric generator is based on an OpenSCAD file in which you can modify parameters such as the enclosure dimensions, the position of the feet, the size and placement of ventilation openings, wall thickness, corner radius, and many other features. As the final output, the generator produces separate STL files for the top and bottom parts of the enclosure, ready for 3D printing.

This project demonstrates how to build a real-time GPS tracker using the Heltec WiFi LoRa 32 V4 and the REYAX RYS352A GNSS module. The tracker hosts its own web interface, allowing any device on the same Wi-Fi network to monitor live location and travel history directly from a browser. The project processes NMEA data locally, displays live coordinates on the onboard OLED, and visualizes the current location and travelled path on OpenStreetMap without relying on cloud services.
