For the past few weeks, we’ve been teasing the release of the Summer Circuits 2022 edition of Elektor Mag. The wait is over. Now it’s time to enjoy the 140-page issue, which is packed with more than 52 inspiring circuits and projects.
 
The Summer Circuits edition comprises circuits, projects, in-depth articles, and even an interview. In typical Elektor fashion, we’ve planned a little something for everyone, from the pro engineer in Munich to the student in Amsterdam to the maker in San Francisco. Let’s take a look at what’s inside this collector’s item!20220714112759_elektor-summer-circuits-2022-en.png
