How To: Solder a resistor to an LED

A basic instruction for electronic enthusiasts. I use an RGB LED and a 510 ohm resistor as I may change from 6 to 9 volts later, but with my LEDs i could go as low as 330 ohms. I sacrifice some brightness for the sake of longer life. To choose your resistor, the value in ohms = voltage of your batteries or power supply / (as in divided by) the amperage that your LED needs to run.

How To: Find percent by mass & percent composition

In chemistry you come across problems which ask you to find the percent by mass and percent composition of each element in a chemical compound. To do this the first step is to compute the molar mass. Use the periodic table to look up the mass of individual atoms and multiply it by the number of atoms to find the mass of that element. Now add up all the masses to arrive at the molar mass of the compound. Now to find the percent composition of an element divide the total mass of each element by...

How To: Build a PWN circuit to control power that can dim an LED, control a motor etc.

Many types of circuits are useless and less useful if you cannot control the amount of power going through them. For that, you need a PWN (pulse with modulation) switch. This electronic component will let your control the power going through the circuit, enabling you to dim LED lights, control the speed of a motor, and other useful tasks. This video will teach you all PWN switches and how tom make your own.

How To: Calculate weight if given the mass

The video shows how to calculate weight if the mass is given and vice versa.Later on in this unit you will learn about Newton's laws of motion and Newton's second law of motion gives us a way to change mass into weight and vice versa.This law will tell you what is happening to objects when the net force on the object is not equal to zero and the easy way to say what will happen is that the object will accelerate.But how much the object accelerates depends on two things,firstly the mass of the...

How To: Gmask your gadgets

In this short demonstration, see how a Gmask is made for a cell phone. A Gmask is a DIY skin for your gadget (such as a cell phone or iPod), that could last and protect your electronic device for up to 7 years if made correctly. The Gmask at times covers your gadget's corners, edges, screen and even keypad in some cases.

How To: Calculate weight average atomic mass of an element

In Chemistry weight of some elements are measure in the form of Average Atomic Mass. Isotopes are found in different abundances in nature. Certain elements have many isotopes and certain elements have few isotopes. Regardless of the number of the natural isotopes, the weighted average mass takes into consideration not only the mass of each isotope, but what also its natural abundance in terms of percent as found in the nature. So when you have the mass of two isotopes of an element and are gi...

How To: Easily tune a guitar without using a guitar tuner

Sometimes you need to tune your guitar to another instrument, or you'll need to tune it when you don't have an electronic tuner handy. This video shows you how to do that. Start with the A string, and make sure that's in tune with the other instrument. Put your finger on the fifth fret of the low E string and play the E and A strings together. If they sound the same, they're are in tune with each other. If not, adjust the E string to make it match the A. Next, tune the D string by fretting th...

How To: Calculate weighted atomic mass

This video is about Level 2 atomic concepts, specifically the Pennium Lab. This helps you understand how atomic masses are derived for the periodic table. This teacher demonstrates how to do the calculation. He first reviews the Isotopes as they are different masses of the same type of atoms. He uses chromium as his example. It has a different number of neutrons in the nucleus. Using the equation, it could have either 26, 28, 29 or 30, with its 24 protons. So he subtracts the atomic number fr...
