Elektor Circuit Special 2023
In the summer of 2022, Elektor brought back its Circuit Special edition. It was well-received by long-time readers and new members alike! Today, we are excited to present our the Elektor Circuit Special 2023. With a nod to our past and a look to the future, the 2023 edition showcases the work of dozens of innovative engineers and makers from around the world. Just like last year, we emphasize simple circuits and creative projects, and we happily added dash of nostalgia. Download here your digital bonus edition.
Curious what’s covered in the Elektor Circuit Special 2023? In typical Elektor fashion, we have something for everyone, from the pro engineer to the ambitious maker: a tiny solar supply, a DIY Li-Ion battery monitor, Elektor’s classic One-Armed Bandit, a power overload monitor, a programmable fitness timer, and much more. On this webpage, we offer links to project files and downloads accompany the articles in the edition. We also offer access to a few resources that will help you get started on your project. Enjoy the issue!
