Toy/Hobby DC Motor Fun
Toy DC Motors, also known as Hobby DC Motors, can be a good choice for low-budget or pocket-friendly basic electronics projects. They are very rugged, easy to use, and generally available with a wide range […]
Tutorials on electronics for beginners, hobbyist, and experienced geeks. Electronics is a vast area that covers analog and digital systems. Codrey explains how to build your own analog circuits and transforming them into digital blocks.

As promised, this is a follow-up to the Quick OLED Thermometer post covering a few things about customizing the OLED display splash screen. Oh, I could not get this posted here at the intended time, […]
A handheld engraving pen can be used to create permanent and precise designs in hard surfaces like plastic, metal, wood, and the like. Inside the pen, there is a battery and a small electric motor […]
We all know that a reverse biased silicon diode can be used as a make-do temperature sensor (https://www.codrey.com/learn/bjt-diode-temperature-sensors-a-quick-walk/). But let me remind you again, a silicon diode, when reverse biased, will introduce a certain leakage […]
So, I am revisiting emitter follower this moment and sharing my dusted thoughts on it. I hope this post helps someone one way or another! This article mainly looks at an emitter-follower (also known as […]
As I mentioned and proved in an earlier write up, a regular light emitting diode can also be used as a light sensor (https://www.electroschematics.com/led-2/). So, this is a post that goes into a bit more […]
While testing some cheapo crash sensor modules recently, I was quite disappointed with the noisy and dirty output signals they provided. So, I got into the thoughts of restyling hardware debounce circuits suitable for contacts, […]
The LM385 is a micropower two–terminal bandgap voltage regulator diode. It is designed to operate over a wide current range of 10mA to20 mA, and features exceptionally low dynamic impedance, low noise and stable operation […]
Sometimes you may need ready-made hardware to set up a simple timer to help you control something at the right time. No wonder, Chinese electronics have many instant solutions for that, the simplest of which […]
If you often drive early in the morning or at night, you spend most of your time in a dark vehicle, and at that time a small interior/dome/cabin light becomes an indispensable widget if you […]
