How to Build a Simple LED Cube 4x4x4 - Part 2

Building the Cube Structure

In part one we prepared all LEDs for the assembly of the cube. Now, we start in earnest...


Step2: Build the groups
Each group consists of eight LEDs. Here they are:







You need a template to assemble the LED groups. My LEDs are 5mm, so I drilled a set of 8 5mm-holes in two rows with 4 holes each into a piece of wood.







Insert 4 LEDs in the upper row of the

Electrical Contactors AC1, AC2, AC3, AC4

Image
Electrical Contactors Utilization Categories:- Electrical Contactors are categorized according to the current making and breaking values for contactors. This will depend on the following: The type of load to be controlled (Inductive load, Lighting load, Motor load, Resistive load, Capacitive load) The operating cycle conditions. For any applications there are different contactors available depending upon load application which every electrical engineer you must know before designing any systems.  You may have often seen the ratings described on contactor name plate depicting various parameters. One of most important to be considered are as described in this article.  AC1 - These type of contactors are used for Non-inductive or slightly inductive loads they are used for Heaters which are resistive loads. AC2 - These type of contactors are used in Starting of slip-ring motors AC3 – They are particularly used for Starting of squirrel-cage motors and sw...
