Perl Tutorial

Perl TutorialThe number one request I’ve received is to create a Perl tutorial so here it is. I cover basically what you would learn in a 250 page book in this one video. We’ll learn all the basics plus pragmas, scalars, arrays, hashes, printf, print, math functions, conditionals, boolean operators, if, elsif, else, unless, ternary operator, looping, for, foreach, while, do while, reading input, given, strings functions, s///, ranges, slice, sort, push, pop, join, subroutines, recursive subroutines, packages, object oriented Perl and so much more.

All the code as well as a transcript follows the video below. Continue reading Perl Tutorial

Electronics Tutorial 4

Electronics Tutorial 4In this part of my electronics tutorial I’ll focus on transistors and also review what I’ve covered in previous parts of this series. If you haven’t watched the previous videos watch them first or you’ll be confused.

A transistor is a semiconductor component that is used to amplify or switch electronic charges. I’ll show how they are used as switches and amplifiers. We’ll see how changing voltages at the base effects the transistor. We’ll cover the Darlington configuration. Then we’ll create a fun voltmeter. All of the circuit diagrams follow the video below.

Electronics Tutorial 3

Electronics Tutorial 3In this part of my electronics tutorial we’ll cover Voltage Drop, Capacitors, Variable Resistors, Potentiometers, Rheostats, Diodes, Schematic Diagrams, Electronic Circuit Diagraming Software and much more.

If you missed part 1 or part 2 definitely watch those first or you may be confused. All of the circuit diagrams can be found below the video along with a transcript of the video. Continue reading Electronics Tutorial 3

Electronics Tutorial 2

Electronics Tutorial 2Welcome to my 2nd electronics tutorial. If you missed the 1st video watch it first. This time well learn many of the basics that you’ll need to start making and understanding circuits. I’ll be covering Current Flow, Reading Schematics, Using Multimeters, Voltage Drop, Series Circuits, Parallel Circuits, Using Bread Boards, Switches, Resistors in Series, Resistors in Parallel and more.

Bread board photos are below so it will be easy to make the circuits. I’ve also included a transcript of the video plus more info not covered in the video below. Continue reading Electronics Tutorial 2
