In this tutorial I am going to create a chaser circuit that can drive 20 or more LEDs using 555 timer IC and CD4017 decade counter.

Created a small "PCB Christmas Forest" which is going to light up my study table this Christmas.

In this tutorial, I will show you guys how I designed and assembled the humidifier circuit into the 3D model.

In this tutorial I'll show you guys how to make this super simple 4x4x4 PCB LED cube "without over complicating anything".

I am going to use this screen to create a touch panel for my home automation system.

Had some time this weekend and a desire to create something new and interesting, so went ahead and created an Arduino/NodeMCU based indoor dial thermometer.

In the year 2021 I created a "Internet Hardware WatchDog" using NodeMCU which reboots my home router whenever there is an issue with the Internet. This device sits next to my router and happily takes care of it whenever it has a hiccup. This year, I wanted to extend the watchdogs horizon by adding an "Internet Status Notifier" that displays the current status of the Internet using an RGB LED.

My curiosity to create something new and interesting got me into this gothic style rechargeable lantern. A Gothic Lantern is a captivating piece of lighting that brings the allure of the Victorian Era into your home.

In this tutorial, I am going to use the ULN2003 IC to create a simple, inexpensive water level indicator.
