Pi network attenuator circuit. SpinningSpark (CC BY-SA 3.0). A Pi network attenuator is a simple three-resistor circuit, as shown in the diagram to the right.

An anti-log amplifier design with a temperature-compensation network built around a nearly linear PTC thermistor.

Calculating the appropriate resistor values for a photocoupler isn’t complicated, but some basic min/max considerations must be acknowledged in when doing the analysis.

Hackaday Editors Elliot Williams and Tom Nardi meet up virtually to talk about the week’s top stories and hacks, such as the fine art of resistor trimming and lessons learned from doing overs… ...
