Automatic Aroma Diffuser (v2)
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 […]
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.

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 […]
A non-contact voltage tester (NCV Tester) makes electrical work easier and safer – and for a few bucks you can own it from your nearest home improvement center. The NCV tester is a simplest and […]
Float switch a type of level sensor that float on the surface of a liquid. It basically consists of a hollow float body containing a sensor or switch. As the liquid level rises/falls, the float […]
I have been using several microwave motion sensor doppler radar modules for years, but in cases where an ultrafine movement detection is demanded, those cheapo modules did not perform well. So I decided to have […]
This article shows basic circuit ideas for pulsing low power visible semiconductor lasers using inexpensive components which are fairly readily available. First of all, you need to know that this is a very belated sequel […]
Get ready to make a smart badge or a simple wearable device such as a wristband, lanyard or watch-style device for your smart kids. And, introduce your kids to electronics and microcontrollers without them even […]
I think you’re all familiar with the various Chinese sensor modules based on the LM393 IC. That’s good, but at this point I’ll share the design idea of an LM358 IC based variable threshold solid […]
I recently picked up a bunch of minuscule Chinese USB LED Lamps. You’ve seen these amazing gizmos before, I’m sure, under a variety of names in places ranging from local street merchants to online electronics […]
A while back, I got an inquiry via email about building a simple electronics circuit to monitor the status of an analog sensor i.e., whether it is open or working properly. After a little discussion, […]
