I made this as a Christmas present last year. This is a small color-changing RGB LED orb light controlled by Raspberry Pi Pico. I got the inspiration for this project from the Chinese-made USB-rechargeable color-changing […]
Since every machine has its own vibration signature, drifts in a machine’s vibration can indicate potential faults. There’re multiple types of vibration sensors available to keep tabs on a machine’s vibration, and a widely used […]
Prolonged blackouts have always been an annoyance, but with the help of today’s portable inverter lamps/bulbs, tackling them has become much easier. Below you can see such an affordable LED Inverter Lamp from Osram (India). […]
This quick intro post tells you something about converting radio-control (RC) hobby servo pulse width modulation (PWM) signals to pulse position modulation (PPM) signals using commonly available systems and components. At this time, you can […]
This post explains how to build a mini PCB drill speed controller using a handful of common components you may already have stocked in your home lab. First off, let me say that this idea […]
In this post, you will find the construction details of a crazy bomb timer that can be built with the help of a handful of common electronics components available everywhere. Well, get ready to entertain […]
Flashing yellow lights are an essential part of sliding/swing gate and garage door automation systems, since they provide a clear indication that the system is installed and in operation. Thanks to LED technology, the total […]
This little post is about modifying a standard LED Tap Light/Stick Touch Light to run on the Arduino platform with additional features. Okay, let’s get started! Tap Light? So, what’s a Tap Light? Simply, the […]
As an active electronics hobbyists, I get to see a lot of applications for NeoPixel LEDs. In fact, this new breed of smart LEDs is great for a large number of fabulous hobby projects that […]
The objective of this little, and a bit odd, experiment is to explore the use of a single LED as a fancy glowing eye for toys and the use of a BJT as a simple […]
