Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...

This rugged current-sense transducer provides high performance along with high isolation for applications ranging from solar power to EV charging. Sensing current, especially in higher-voltage ...

Competitive gaming equipment, such as controllers and keyboards, have recently seen some major changes to their design that make them more efficient and reliable than ever before. One of the most ...

We’ll beat everyone to the punch: yes, actually building a working Turing machine, especially one that uses a Raspberry Pi, is probably something that would have pushed [Alan Turing]’s buttons, and ...

We’re always happy to see hackers inspired to try something different by what they see on Hackaday. To [SimpleTronic] has a project that will let you stretch your analog electronics skills in a really ...
