And Some General Comments on Cheap NiMH Batteries In this opportunity, I want to present my recent discoveries on the measurement results of some old NiMH batteries. These batteries are old. I think they are in the order of 3 – 4 years old and some have undergone medium duty usage, while some has gone under heavy duty… Read More Effects of Long Term Usage on NiMH Batteries

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
