What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...

The 859 Series DIN-rail timer relay module offers on-/off-delay timer modes and multiple time ranges for applications such as switch and package de-bounce sensors.

WAGO Corporation's 859 Series DIN-rail Timer Relay Module offers On-/Off-Delay timer modes and multiple time ranges for diverse applications such as switch and package "de-bounce" sensors. Unlike ...

We often marvel at the many things a 555 can do. But [Zafer Yildiz] shows us that it can even take the place of a PCB. You’ll ...

The initial plan was to use the ubiquitous 555 timer IC to build the feeder relay module. But then I chose an Arduino microcontroller. I wanted to build something that would happily accept potential ...
