How To: Turn Any Wall Portrait into Your Own Personal Scooby Dooish "Eye" Spy Surveillance System

Remember how the bad guys in Scooby Doo would always use cut-out portraits to spy on people through walls? Well, unless your landlord is super cool, you probably shouldn't start cutting holes in your wall just yet, but you can make a higher tech version, thanks to NASA employee Mark Rober. Mark used a cheap picture frame and a portrait with the eyes cut out to make the "Scoob Cam," which also doubles as a surveillance device. He used an iPhone and an iPad to start a FaceTime chat, then taped ...

How To: Search for Photos on Your Computer by Exact Dimensions

As a technology writer, phone screenshots can pile up on your computer in no time. Testing out different apps, showing buggy software, and doing step-by-steps can lead to a plethora of mobile screenshots piling up on your computer's desktop. The problem with my screenshots is that they save as photo.png or photo.jpeg, as do many of my other photos. If I haven't finished a project or article, I tend to move them to different folders to save them for later. After a while, the screenshots begin ...

How To: Build Your Own Projector Screen at Home for Less Than Fifty Bucks

In the video below, How To Lou shows us how to make it with just some white or silverscreen paint, a few pieces of casement molding, and some black velvet for the trim.

How To: DIY Flanagan Neurophone Lets You 'Hear' Sounds Through Your Skin

In 1958, Patrick Flanagan invented the Neurophone, a device patented in 1962 that allows radio signals to be picked up by the human nervous system. The skin is the organ that receives the signal, converting it into a modulated molecular vibration, which the brain interprets into sound. Basically, it gives one the ability to 'hear' through the skin, making it sound like the audio you're hearing is actually in your head. It's kind of like having headphones in your brain. The only problem was th...

To start, you will need to analyze how many atoms in each chemical you have on each side. Once you do this, you will need to find what you can multiply by on each side to make them equal to the other side. Once you do this and have equal atoms on each side, then the equation will be equal. Remember that you cant have a half of an atom, so that...

How To: Use functioning & static dominant chords in jazz guitar

In this video, we learn how to play Jazz guitar: Functioning & Static Dominant Chords. When you play an A7 going to a D chord, you are playing a functioning dominant, because a five chord always wants to go to a one chord. This is because of the tension in the five chord and how it resolves to the one chord. You will hear that the chord wants to go to a different chord, so make sure you understand this concept as you are playing. If the chord does go to the other, it's referred to as a functi...

How To: Solve math problems using proportions

Proportions or ratios are fundamental concepts of mathematics. A proportions is an equation that states that two ratios are equal. Hence proportion can be written in two ways as a:b=c:d or a/b=c/d. In these equations a and d are called as extremes and b,c are called as means. So when working with proportions we can state that product of the means is equal to the product of the extremes i.e. a*d = b*c. This is obtained by cross multiplying the second form of proportions. In mathematics you are...

How To: Solve the 4x4 Rubik's Cube Revenge in seven steps

Solving the Rubik's Revenge Cube is similar in concept to solving the original Rubik's Cube. You still match colors and replace one piece with another, but there is an added level of complexity. Where the classic Rubik's Cube has fixed centers that determine the color of each face, every piece on the Rubik's Revenge Cube is fully moveable. It is also much more fragile than the original Rubiks Cube therefore requires greater care and precision. If you want to more... just watch and learn.

Two college students; Kevin Martin and Joey Smokey introduce the concept of Molar Mass. They start of by explaining what molar mass is, which is the relationship of a mole and a gram, it totals up the weight(in g)of a molecule. An example: say you have this compound, Sodium phosphate (Na3PO4). You know you have three sodium atoms, one phosphorus atom, and four oxygen atoms. You basically find the weight of each atom, if you have three sodium atoms, you multiply it's atomic mass by 3 (the numb...

How To: Understand nth roots and operations on radicals

This video teaches us the concept of nth roots. The video starts with the square root of constants. We find the number which when multiplies by itself for two times results in the constant inside the square root. Then we find the square root of variables. Here again the same concept is used. We find the variable which when multiplied by itself for two times results in the given variable. Then we find the cube root. Here we find the number which when multiplied by itself for three times result...
