Garden guardian
A soil-moisture-sensing, pump-controlling ESP32 micro-garden minder. Necessary? Obviously not.

I'm Mark — a mechatronics engineer with a bench full of microcontrollers and a head full of strange ideas. I make fun things and then I share how I made them. Come learn from and laugh at whatever I come up with next.
A soil-moisture-sensing, pump-controlling ESP32 micro-garden minder. Necessary? Obviously not.
Particle sensor + RP2040 mounted to the bench arm. Tells me when to crack a window.
Computer vision on a Jetson Nano. Tracks the cat. The cat does not approve.
A handheld software-defined radio in a 3D-printed grip. Listens to things it probably should not.
Gutted a 1970s analog meter, kept the needle, drove it with a DAC. The needle is happy.
Lego sparked it, university gave me the tools, and now I build mechatronics projects for the love of it. Mech Mark is where I document the results: the builds that worked, the boards that fried, and the eureka moments somewhere in between. Hopefully it inspires someone else to bring their own weird ideas to life.
