Your Weather App Is Eating 200MB to Show You a Number

Weather data is tiny โ€” a few bytes of JSON. Yet typical weather apps consume hundreds of megabytes of RAM. The real inefficiency isn’t the app; it’s the entire OS and GUI stack it runs on. An ESP32 with an ePaper screen can do the same job with a few kilobytes. Efficiency is a design choice we’ve stopped making.

The ‘Vibe Coding’ Hype Is Wrong. Here’s How One Engineer Actually Used AI to Build a Bowling Lane.

The ‘vibe coding’ hype is wrong. One engineer used AI as a research assistant, not a crutch, to build an open-source ESP32 bowling lane automation system. The result? A real project that works โ€” and a lesson in why owning your design decisions still matters.

Stop Building AI Data Centers. This $8 Chip Just Trained Its Own Model.

An $8 ESP32-S3 microcontroller just trained a language model from scratchโ€”319K parameters, two days, zero cloud. It barely works, and that’s the point. While the industry obsesses over scaling up, the real frontier is scaling down: AI that learns on-device, preserves privacy, and costs less than lunch. The underdog era of AI has begun.

The Web Is Broken. Here’s the $5 Fix.

Babe32 is a $5 ESP32 microcontroller that can browse the web in monochrome, proving that modern web bloat is not a necessityโ€”it’s a choice. This minimalist browser challenges assumptions about digital equity, environmental impact, and what we truly need from the internet. It’s a quiet rebellion against the corporate, ad-ridden, resource-hungry web we’ve accepted as normal.

Your DIY Radar Isn’t a Radar. It’s an API Consumer. And That’s Killing the Maker Spirit.

A popular ESP32-based ‘radar’ project is actually just an API consumer for adsb.fi. This isn’t a critique of the projectโ€”it’s a wake-up call for the maker community. We’ve traded real engineering for convenience, building fragile interfaces to cloud services instead of devices that actually sense the world. Are we building sensors or just signs?
