Here at Po’Man’s, our motto is “Why pay big bucks for expensive tools, when there might be a cheap way to get the job done?”


Lattice Wave Digital Filters

This article, and the accompanying design tool, were a result of my investigation into LWDFs which were just too cool to pass up.


A Logic Analyzer Tutorial - Part 2

Part 1 gave you an overview of logic analyzer basics. Now, let’s concentrate on actually using this instrument. We’ll examine some of its limitations and its numerous, powerful features that make it so useful in the lab...



Projects

Build a Remote Battery Bank Voltage Monitor

Everyone has heard the saying “necessity is the mother of invention.” Well, that is what gave birth to this project.
