Field Reprogrammability for Flexible Automation Control Applications

In my post before, I have analyzed a handful of rechargeable battery both old and new in an attempt to gain practical information as to what happen to them over time. The observation is made possible only by what I call, “A stable measurement platform” based on a 68HC908QB8 CPU from NXP (in the old days,… Read More Field Reprogrammability for Flexible Automation Control Applications

Using Transistor-Based Schmitt Trigger as Astable Multivibrator

In this article, I would like to write about my recent experiment in constructing schmitt triggers using discrete components. I have constructed 2 versions and the latter version is employed in a flip-flop. This whole excercise is done just to see how they behave, and seeing transistors flip and flop is kind of amusing. Classic… Read More Using Transistor-Based Schmitt Trigger as Astable Multivibrator
