I’ve recently completed the basic design of a general-purpose analog constant current generator employing easily available electronics components. This is a simple circuit that is easy and cheap to build and is very useful especially […]
Welcome to the lovely sound of analog electronics! Now I’m building some white noise and pink noise generators for an upcoming amateur audio project. In this article, you can see a few basic design ideas […]
The prime intention behind this little post is to share some notes about analog optocouplers which might be useful for hobbyists, students, etc. I know many novices who want to learn the secrets of analog […]
I’ve been asked if I could post a little primer on key components widely used in guitar electronics and special-effect units. While there’re no solid plans to do so yet, I was thinking about what […]
This is a quick primer on analog signal processing, which lets you smooth out the noise from analog readings in Arduino microcontrollers, resolving one of the major disquiets of analog sensor inputs, very easily. Recently, […]
Assume that you’re in the middle of a microcontroller-based project with a big array of sensors and transducers ready and waiting to get their I/O allocation by the microcontroller, and sadly you found yourself there’s […]
Let me introduce another simple do it yourself project, this time an electronics thermostat for residential electric water heaters. The circuit is designed for use in two-element water heaters in the upper position (upper thermostat), […]
Recently I got an unusual query from a newbie microcontroller hobbyist on how to drive an electromagnetic relay using a bipolar junction transistor (BJT). Admit it, analog electronics is not a piece of butter cake […]
