FooBarOur blog is live — and so is its first article.
Helix wanted to try their hand at a physical DIY project for once — most of their work is purely software. The goal: build a portable temperature & humidity monitor from scratch to tackle a real problem at home: poor insulation and rooms humid enough to grow mold.
ESP32 + DHT22 + a few euros of AliExpress parts. The article covers the circuit design, prototyping, and some tricks along the way. It's a work in progress — more updates coming as the project evolves.

DIY portable monitor for temperature & humidity
The need for a hands-on project Almost all of my personal projects rely entirely on software solutions, in which I either set up existing tools or write them myself. Even though the projects and software in question vary greatly, interacting only with code can get stale after a while. This encouraged me to start a hands-on DIY project. It specifically appealed to me since I’ve rarely built anything physical during my education, so it was mostly uncharted territory. I looked for something in my daily life that would benefit from a simple device I could build myself.
