I Built an RFID Jammer by Accident | Here’s How It Works
I get asked a lot if I sell pre-assembled ESP32-DIV units. Right now, the answer is No. The project is still in development, and I need to address flaws in both hardware and software. I’m not willing to sell something that’s not ready. A reliable version is coming 🍻

Wasted an hour messing with soldering and code, trying to figure out why my I2C line was dead. Turns out, it was just a super tiny solder speck screwing things up. 🧠

It’s surprising how many Sub-GHz signals you can pick up at a mall. This experiment gave me some great ideas to improve the Sub-GHz features of the ESP32-DIV.
Built ESP32-DIV. Now my neighbor’s smart fridge thinks it's 1998 again. ❄️
