Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Solid State Relays (SSRs) and Solid State Contactors (SSCs) are ideally suited for controlling dynamic loads such as motors, particularly where frequent or multiple start/stop cycles are required in ...

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

Abstract: Design tests for relays, relay systems, and control devices used for protection and control of electric power apparatus that relate to the immunity of this equipment to repetitive electrical ...

[Udo] figured out how to turn a bunch of LEDs into a very low resolution camera. The build is based around [Udo]’s Blinkenlight shield he’s been developing over the past year. The camera operates ...
