This Batman retractable gauntlet project is being refined with stronger mechanical locks and magnetic electronic controls.

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

Tablets like Apple’s iPad have Hall sensors built into them. The idea behind these sensors is that they can detect magnetic fields, allowing them to be used with cover accessories that turn the ...

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, ...
