My name is Petr Šrámek, and online — and in the maker community — I’m known as Chiptron. Since 2007 I’ve run Chiptron.cz, where I share practical guides and reviews about microcontrollers, electronics, and embedded systems. Everything I publish is built, tested, and often rebuilt, so it helps both beginners and experienced engineers.
I got into electronics before college — soldering, microcontrollers, and later my own PCBs. I earned an electrical-engineering degree at the University of West Bohemia in Plzeň and have always wanted to connect technical skills with community work.
Today I’m an application engineer at an international company. The daily challenges I solve there often turn into articles, tests, or debug notes on the site.
I’m active in the community offline as well. I create workshops, talks, and tutorial series. With Laskakit I write guides for new modules and help expand the local supply of affordable dev tools. I organized the Cena bastlířů awards for interesting DIY electronics projects and helped start the yearly Bastlířský kalendář, where makers showcase their creations. These projects show how active and community-based the Czech maker scene is.
Besides common MCUs I also explore less common chips like the RP2040 and CH32V series, non-standard uses such as art, home automation, or teaching kits, and modern low-power design methods. I follow and contribute to open-source software and hardware.
Chiptron.cz isn’t a commercial site or personal blog; it’s a hub with lab notes, test logs, and an open forum for anyone who wants to dig deeper into electronics while keeping the fun of discovery. I enjoy pushing my own skills, and I’m just as happy when someone gets their first sensor working, wires an I²C device correctly, or learns why their project freezes after six seconds.
A strong tech community runs on sharing, trust, and learning from each other. If hacking for you is more than soldering parts, you’re in the right place.
