The Slowtronics store is finally LIVE.You can now get my gadgets shipped straight to your door. More weird, useless and ridiculously fun electronics coming soon.Go check it out: slowtronics.com

This little ESP32 is trying to mine Bitcoin by making random guesses. The chances of actually finding a block are insanely low, but technically not zero.Think of it as a lottery ticket that never stops playing. You can watch the hashrate, connection, netw

Built a sort of “EMP grenade” for under $10 using an ESP32, and a nRF24 module.The device creates heavy interference on the 2.4 GHz spectrum, which is the same band used by WiFi, Bluetooth, wireless speakers, headphones, smart devices, and a lot more.The

I wanted to see if I could build a Theremin without any of the fancy stuff, so I made this little monstrosity with an ESP32 and two cheap light sensors.One sensor detects how much light is reaching it and uses that to control the pitch. The other one cont

What if your ESP32 could become a gaming controller?For this project, I turned a tiny ESP32 board into a wireless motion mouse that can control my computer over Bluetooth. And yes, I even used it to play DOOM.The main component is an MPU6050 gyroscope, wh

I made an ESP32 captive portal that looks like a “Free WiFi” network… but there’s a little surprise waiting for anyone who connects.It automatically rickrolls you. Never gonna give you up.Want to make one yourself? I put the full tutorial on my website. L

Electronics made so accessible, even a complete beginner can master it. 🔌✨I built a full graphical operating system inside a $5 ESP32 board. No setup, no IDEs, zero code required.Here’s how it works:📡 Plug & Play: The ESP32 creates its own Wi-Fi network.

A servo + an accelerometer + an ESP32 = a tiny creature that moves based on how you tilt it.The servo is a small motor designed to move to a specific position. Unlike a regular DC motor, you can tell it exactly where you want it to go, and it will rotate

Can a tiny $5 microcontroller break into a Wi-Fi network? I built this device to audit my own network and show why online brute-force attacks fail against basic math.Here is what is happening under the hood:1️⃣ The Target: The ESP32 scans 2.4 GHz frequenc
