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 […]
There are many ways to use standard hobby servos in do it yourself projects. I semi-regularly hear about design concepts that I’m not familiar with. Recently, I had a reader, who’s an amateur toy maker, […]
Not all Arduino projects demand all GPIOs. ATtiny85 microcontroller certainly helps in miniaturizing such projects as required. So, for simple projects, the ATtiny85 can be a great choice. Recall that the ATtiny85 microcontroller chip is […]
Water outflow alarms (flood sensor alarms) are arguably the most widely used commercial water leak detectors since they are cheap and easy to install. A water outflow alarm helps protect your home and belongings from […]
Hopefully this short post will give you some practical pointers for making your own LED spotlights that also includes a servo actuator. There are dozens of different ways to drive standard hobby servos, and here […]
Xmas star is more than just a lovely ornament. The Xmas star is also known as the star of Bethlehem and is a major seasonal symbol throughout the globe. Well, Christmas is just around the […]
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 […]
Not long ago, I played around with making an overheat sensor siren on the Arduino Uno, which I later modified a bit and incorporated into another hobby electronics project. Needless to say, it worked fine. […]
The goal of this little post is to share an idea to build your own robust mud water detector using readily available inexpensive electronics components. Although unintentional, the sensor component in this design concept is […]
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 […]
