Wow! According to Youtube's statistics, the video about my charlieplexed LED cube was watched over 100,000 times. Unbelievable! Unreal! Unforeseen! Thanks for all your interest and all the positve feedback. I don't know if I will be able to top that, but I will keep trying,

Update Build this simpler version instead! Introduction When I wrote my post on my charlieplexed LED cube, I never meant to publish build instructions. There are plenty of instructions around and a regular LED cube is much easier to make. Instead, I wanted to show that it is possible to use charlieplexing for such a cube. And I wanted to share my thoughts on how I got there. So I never

Features Low cost and low part count Four different flashing patterns, easily modifyable Speed control and pattern switching via pot Introduction This is nothing special, really. "Knight Rider lights" or "Larson Scanners" seem to be very popular microcontroller projects. I guess they are the next step right after the blinking LED (a.k.a. the "Hello World" program for microcontrollers). I

Reverse Engineering a Solar Lamp Part 1 of this post is a write-up of my project for a thermometer with Morse code output. But I was not satisfied with the relatively high power consumption of the circuit, so I decided to use a solar cell to supply the circuit. A cheap source of solar cells these days are solar garden lamps. You get them for very little money in garden centres and DIY shops.

Newton’s law of viscosity is given by Ƭ = µ du/dy Where, Ƭ = shear stress. µ = absolute or dynamic viscosity. du/dy = velocity gradient. Newtonian fluids: Fluids which follow this law are known as Newtonian fluids. Example of Newtonian fluids are Air, water etc. But non Newtonian fluids are tar, paste, blood, glycerin etc.

A fluid may be defined as a substance which deforms continuously when subjected to a shear stress or in other words a fluid is a substance which cannot withstand shear stress. Fluid mechanics deals with the behavior of fluids at rest and in motion. Fluids may be of liquid or gaseous forms. Liquid is practically incompressible and occupy definite volume and have free surfaces. Whereas, gaseous

A system is defined as a region in space containing a specific amount of matter whose behavior is being observed. The system is separated from its surrounding by a boundary. The boundary may be a real one or some imaginary surface covering the region. The boundary may be at rest or in motion and may change its size or shape. The term surrounding is restricted to those portions of matter
