Tilt sensors come in umpteen flavors. The cheapest and most common flavor is the belittled SW-520D tilt sensor module you can find everywhere. Key component in the demoed module is one SW-520D ‘roll ball switch’ […]
With this article, I’m trying to share one simple idea on how to build a single-key touch pad sensor/switch using a quick and cheap Chinese module. We can easily build a simple touch sensor using […]
This article is about building a little hydrophone that can be used to record underwater sounds. Professional hydrophones used in science world are relatively costly, and even do it yourself ideas feature expensive components. As […]
Let’s make a quick and dirty foam cutter! Foam is an easy and cheap material for various prototype creations, and cutting the common polystyrene/Styrofoam is easy with a hot wire cutter. Now do it yourself […]
A fan failure in today’s advanced electronic projects may result in other delicate and expensive components failing, causing costly repairs and delays. A 3-wire PC fan is an easy and inexpensive way to prevent such […]
Having spent a few days messing on with building simple inductive proximity sensor circuits, I’m putting together anew inductive proximity detector device for a small-scale industry. I already have an expandable idea with the sensor […]
If you build battery/usb powered electronics projects, often you’ll be in need of a high-voltage power supply. That is a power supply that has an output voltage higher than that catered by the battery. One […]
In this article, I’ll dig into everything you need to know when it comes to the build of your own minuscule wired/wireless spy camera system. Since the spy camera itself is one of the most […]
Here’s a simple and clever way to build a toggle switch with a quite popular, highly available, and cheap CMOS logic chip CD4049UB. Since the little electronic toggle switch presented here is an easy to […]
