Had some time this weekend and a desire to build something new and interesting. So, went ahead and created this masterpiece using some free pallet wood. 3D Design Before getting our hands dirty with sawdust, lets design the 3D version of this project to get all the measurements correct. All my…

Created a small “PCB Christmas Forest” which is going to light up my study table this Christmas. In this video, I am going to show you guys how to design these PCBs and assemble them to create a small PCB Christmas Forest. Designing The PCBs Sorting Out Images To start the designing process, I…

Intro In my hand is a 4-Digit 7-Segment display module. The heart of this module is an inexpensive Serial LED Driver from Titan Micro Electronics called the TM1637. In this tutorial, I am going to show you guys how to control the TM1637 4-Digit 7-Segment displays using an Arduino. If…

Intro What do you generally do when your remote controls starts playing up? Do you generally use a multimeter and check the voltage and current produced by the battery? Or do you point the remote control to a digital camera and try to visualize the infrared light? In this video…

Intro Last year I created some Halloween Jacko Lanterns using repurposed pallet wood for Halloween. This year, I thought of creating a Candy Box and some Pallet Figurines for Halloween. Hardware Requirement For this project we need: Pallet Wood Protective equipment like: Face mask Glasses Gloves Sanding Tool Hammer Measuring Tape Nails …

Walkie-talkie using Arduino, humm.. sounds interesting isn’t it? Alright, lets spend some time today and design and understand this fairly simple circuit, and lets find out how our expectations are challenged by the reality. Story While compiling data for my tutorial on “nRF24L01 Module” (All About nRF24L01 Modules) I…

Intro My 5-year old son asked me to create a Police Car like flashing light that he can put on top of his nerf-gun, while playing around with his mates. No worries mate, sounds like a plan to me. Bang, weekend sorted. In this tutorial I am going to create…

The 555 timer IC is an integrated circuit that is used in a variety of timer circuits, pulse generators and oscillator applications. The heart of the tutorial is the 555 timer IC that is wired as an astable multivibrator. In this tutorial, I’ll first blink “an LED” using the…

In my last tutorial I created a NodeMCU based Duino Coin Miner. It is an awesome little miner that sits on my desk and mines few cents a day. However, adding these miners to my home network choked my WiFi router. Home Appliances and Smart Devices connected to the…
