Everyone loves a good desktop decoration. We can also agree that keeping our desks clean is great. So why not combine both? In this Instructable I’ll show you how to make a desktop item that combines aesthetics and cleanliness to create (in my very biased opinion) the best desktop item ever conceived. Just like the

A few months back, I have installed a small-scale Off-Grid Solar System. I am always very curious to see the performance of my solar PV system, and the good news is that the charge controller that I am using has its own local display for monitoring. But, I am badly missing the remote monitoring facility.

Tic Tac Toe is a two player game in which the players compete to get 3 pieces in a row. In this project we constructed a Tic Tac Toe game using a number pad and neo pixels as pieces. This results in a portable Tic Tac Toe game requiring only a wall outlet to play.

There are many smart devices available to us that are able to detect our heart rate and other bio data by using a method called photoplethysmography (PPG), a concept of how blood is able to reflect red light while absorbing green light. The device can detect the amount of blood flowing, so when there’s more

A handy-dandy portable device for testing e-textile sensors on the fly. Sometimes your electronics workspace and your textiles workspace are not the same places. You want to make multiple samples and test them, but then you have to carry your whole electronics prototyping kit (laptop, breadboard, crocodile clips, Arduino etc) and do all the setup.

Random numbers are often used in daily for example in encryption, gambling, gaming and much more. These numbers are generated by computers using complex algorithm but it can be predicated if we know the seed value and the algorithm. So this is my attempt to create over engineered and as far as possible most random
