In one sentence, describe what the following article is about: You can do this either using a Sharpie for a simple circuit or a printed out version from a computer program. Only one of these is needed, so select according to your preference. The schematic should contain a detailed description of all parts, as well as easy to follow connections. If no simulation program is used, assemble and test one or more prototypes of the circuit on a breadboard. Breadboards are very easy to use, and allow one to view the results of a circuit in real time without the need for solder or permanent etches.  Circuit boards are about a dollar apiece, and are simply a layer of copper over an insulator. The typical size is usually 3.5 inches (8.9 cm) by 5 inches (12.7 cm). Drawing is simple; all that is required is an indelible marker, such as a Sharpie. A ruler is also helpful. (Skip this step if you aren’t using the computer program and are using the Sharpie method.) Print the design out from the software's print menu. Make sure the print is on a glossy paper (like those in magazines or separate glossy paper).  Turn on the electric iron (the same one used for clothes). Carefully cut out the design and position it on the circuit board. Put the hot iron directly on top of the circuit board for about 45 seconds. Take the circuit board (careful it's hot). Wash the paper out such that the black ink is stuck to the copper circuit board. Draw out your circuit on your board with the Sharpie. Note that it's really difficult to draw out a circuit design in real life, unless it's as simple as a led and a battery.  Keep in mind that copper cannot be between components, for example, if connecting an LED, there must be a gap in the copper between the positive and negative points of connectivity. Without a gap, the electricity would flow around the LED, as opposed to through it. Remember laws of electricity, all circuits must end at either a negative or ground, or no current will flow. Use thin lines, but lay the ink on thick, it is important that the copper is dissolved before the ink, and that there are no thin patches in the ink exposing copper.
Summary: Select your method of imprinting the circuit schematic on the copper board. Draw the circuit schematic on either graph paper or a simulation programs such as MultiSim or Eagle CAD. If a simulation program is being used, test the circuit thoroughly in the simulated environment. Make sure the circuit functions on the breadboard, or in the simulation software. Acquire a circuit board. Apply a printed design. Alternatively:

Locate the shutoff valve in back of the toilet, connected to a pipe coming out of the wall. Turn this valve clockwise as far as you can to turn the water off. Make the mark at the highest point where the water in the back of the tank reaches. This will help you to determine whether the water in the tank rises or falls over time. For best results, use a sharpie; a pencil mark will work, but it may be washed away if the water rises. Add 1 dye tablet or 10 drops of food coloring to the water in the tank. Dyeing the water this way will allow you to see whether the water in the tank is leaking into the toilet bowl.  You can normally purchase water dye tablets from your local water provider. Be sure to wait at least 10 minutes so that the water in the tank will completely change color. If the water in the bowl has any trace of the dye you put in the tank, the water in the tank has leaked into the bowl. This means the cause of your leak is a faulty flush valve. If you have a damaged flush valve, it will have to be replaced. If the water has risen, this means there’s probably something wrong with the fill valve. If the water has gone down, there’s a probably a leak in your flush valve. If the water level has gone up, check to see if there’s any water in the overflow tube. This would also indicate that the fill valve is leaking and overflowing the water in the tank. If dyed water has seeped out from the bottom of the tank and onto the floor, this means it’s probably a leaky gasket. If dyed water has come out of the body of the tank, the tank itself may be cracked. Unfortunately, if the tank is cracked, it will have to be completely replaced.

One-sentence summary -- Turn off the water supply to the toilet. Mark the water level in the tank with a marker or a pencil. Add coloring or food dye to the water and wait 10 minutes. Check the water in the toilet bowl to see if it’s changed color. Look to see if the water level in the tank has gone up or down. Check if the dyed water from the tank has leaked onto the floor.

Problem: Article: your skin and pat it dry. Wet your skin with warm water and gently rub it with a brush, gentle scrubber, or exfoliating product, such as an exfoliating cleanser. Rinse your skin with cool water and then pat it dry. Exfoliating will remove dead skin cells that would otherwise clog your razor. Dip your clean fingers into a jar of pure coconut oil and then rub your fingers together. The heat and friction of your fingers will soften the oil, making it easy to spread on the skin you're planning to shave. Let the oil sit on your skin for a few minutes before you begin to shave. If you're shaving your face or armpits, you'll only need a coin-sized amount of coconut oil. You'll need more to shave your legs, especially if the skin is very dry. Although you could shave with just the pure coconut oil on your skin, you'll get a smoother shave if you apply moisturizing shaving cream. Spread or brush a thick layer of the cream evenly over your skin. If you're shaving short hairs, you may want to skip the shaving cream since pure coconut oil will be enough to moisturize the fine hairs. the hair with a sharp razor. Rinse your razor with clean water every few strokes, so the razor doesn't clog with hairs or coconut oil. If you find it difficult to rinse the razor, fill a cup with water. Then dip and shake the razor a little to loosen the hairs. Although you can gently wipe your skin with your hands as you rinse, avoid rubbing the skin vigorously. This will irritate the skin and make it appear red. Once you've rinsed the skin with water, take a soft cloth and gently pat the skin dry. Ensure that any little hairs are completely rinsed away before you towel dry. Shaving can dry out your skin, even if you moisturize before you begin. To hydrate your skin and protect it, spread a little more pure coconut oil in a thin layer over the smooth skin. Keep rubbing your skin until the coconut oil is absorbed and no longer feels greasy.
Summary:
Exfoliate Spread a thin layer of pure coconut oil on your skin. Use your fingers or a brush to apply coconut oil shaving cream. Shave Rinse the shaved skin and dry it. Rub a little pure coconut oil on your skin to moisturize it.
