A rack and pinion array is a great way to transform circular motion into a linear one, the problem appears when you try to build it or get it, so we show you how to build an array of rack and pinion, in an economically and quickly way, without any machining.
In any electronic design or electronic experimentation is necessary to feed the circuits and unless we have a useful laboratory power supply we usually have to make some arrangements with the wall adapters, batteries and other stuff. In this guide you will learn how to make a small circuit that will help us solve this problem and provide some functions that are always helpful when working with circuits.
Why do I need a charger to charge my phone or my iPod?
Why does not matter in which way I connect the plug to the wall? Or why does it matter which way I put the batteries?
Because they are two different forms of electricity, alternating current AC and direct current DC.
We all know that if you trigger the wall switch the light is turned on, that our cell-phone at the end of the day tells us that we have 10% battery, if you lick a 9V battery gives us a weird and not pleasant sensation but mostly we know that all of this involves electricity.
But what really is and what are the causes?
Every day we come across objects that affect our lives, since we wake up until we are asleep and even then, they interact in our lives, they make easier the day by day and even happier and simpler.
But, what do I need to bring that idea to reality?
What skills do I need to have?
Do I need an Arduino?
Where do I start?
Take a deep breath and be calm, the answer is closer than it seems.
A power supply is an indispensable tool in the design and testing of circuits, whether you just want to light a LED, working with a microprocessor or design the next generation of computers, you have to interact with a power supply. This guide covers the essentials to work shop or design a power supply.
All you need to know about electricity, in a simple, all without electrocuted in the attempt and not burn your components.

Performed the design of our 4 images (if not already done so check our previous guide), we'll see how to make them a functional piece Fritzing. In this guide we will see step by step:
Fritzing is a fabulous open-source circuit editor for PC / MAC / LINUX . Among its features are the capacity to document your project to and from a Breadboard or in traditional schematic form, the option to design your own PCB's with ability to export to Gerber format and of course, its FREE.
The only disadvantage is that being a relatively new project, does not have some components. That's why we will explain, step by step how to make new Fritzing components using Illustrator.
