I built my own TinyURL-style URL shortener to explore how these systems work under the hood. From generating short codes to handling redirects and storage, this article covers my hands-on experience, the design decisions I made, and what I learned from building a URL shortener from scratch.
Build a Wi-Fi temperature and humidity sensor using the ESP32-C3 SuperMini, a DHT11, and MicroPython, and view live readings through a simple built-in web server.
In this article, we build a captive portal on the ESP32 using MicroPython, allowing users to configure Wi-Fi through a simple browser-based setup page.
In this article, you’ll learn the LEGB rule through clear explanations, practical examples, and real-world mental models that help you debug faster and write cleaner Python code with confidence.
