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.
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 […]
A while back, I came across a set of multichannel optocoupler modules at a discount sale, and what immediately caught my attention was the PC817 dual-channel optocoupler module in that collection. So, this post is […]
What is the point in critiquing a cheap Chinese power MOSFET module, you might ask. But I have a reason for that, because learning something useful from other people’s mistakes (even if they are trivial) […]
As Wikipedia says, a ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or three metal electrodes attached. Like the similar quartz crystal, when connected in an […]
This little post is a quick rescript of RMS and TRMS. As you know, this is not a popular or frequently discussed topic. So, let us jump in! RMS and TRMS RMS stands for Root […]
Last week the prime goal was to revise my design thoughts on automatic aroma diffuser and make a bit amended version for a distant client, again using a bunch of readily available inexpensive components. I […]
There are a lot of different parts in the electronics world, and often parts with the same functionality come indifferent forms and sizes. Now it is the time to pick another cheapo microwave motion sensor […]
