Problem: Article: You can build as large a Tesla coil as your budget allows; however, the lightning-bolt-like sparks Tesla coils generate heat and expand the air around them (in essence, creating thunder). Their electric fields can also play havoc with electronic devices, so you'll probably want to build and run your Tesla coil in an out-of-the-way place, such as a garage or other workshop. You will also want to consider whether it makes more sense to build a Tesla coil from a kit, or gather materials from scratch. Both have advantages and disadvantages in the areas of cost, building time, resources for help, and reliability. To figure how large a spark gap you can accommodate, or how much power you need to make it work, divide the length of the spark gap in inches by 1.7 and square it to determine the input power in watts. (Conversely, to find the spark gap length, multiply the square root of the power in watts by 1.7.) A Tesla coil that creates a spark gap of 60 inches (150cm) (1.5 meters) would require 1,246 watts. (A Tesla coil using a 1-kilowatt power source would generate a spark gap of almost 54 inches, or 1.37 meters.) Designing and building a Tesla coil requires understanding certain scientific terms and units of measure. You'll need to understand their purpose and function to properly make a Tesla coil. Here are some of the terms you'll need to know: Capacitance is the ability to hold an electric charge or the amount of electric charge stored for a given voltage. (A device designed to hold an electric charge is called a capacitor.) The unit of measure for capacitance is the farad (abbreviated "F"). A farad is defined as 1 ampere-second (or coulomb) per volt. Commonly, capacitance is measured in smaller units, such as the microfarad (abbreviated "uF"), a millionth of a farad, or the picofarad (abbreviated pF and sometimes read as "puff"), a trillionth of a farad. Inductance, or self-inductance, is how much voltage an electric circuit carries per the amount of current in the circuit. (High-tension power lines, which carry a high voltage but a low current, have high inductance.) The unit of measure for inductance is the henry (abbreviated "H"). A henry is defined as 1 volt-second per ampere of current. Commonly, inductance is measured in smaller units, such as the millihenry (abbreviated "mH"), a thousandth of a henry, or the microhenry (abbreviated "uH"), a millionth of a henry. Resonant frequency, or resonance frequency, is the frequency at which the resistance to transfer of energy is at a minimum. (For a Tesla coil, this is optimum operating point for transferring electrical energy between the primary and secondary coils.) The unit of measure for the resonant frequency is the hertz (abbreviated "Hz"), defined as 1 cycle per second. More commonly, the resonant frequency is measured in kilohertz (abbreviated "kHz"), with a kilohertz being equal to 1000 hertz. You'll need a power supply transformer, a high-capacitance primary capacitor, a spark gap assembly, a low-inductance primary inductor coil, a high-inductance secondary inductor coil, a low-capacitance secondary capacitor and something to suppress, or choke, the high-frequency noise pulses created when the Tesla coil operates. For more information on the parts, see the next section, "Making a Tesla Coil." Your power source/transformer feeds power through the chokes to the primary, or tank circuit, which connects the primary capacitor, primary inductor coil and spark gap assembly. The primary inductor coil is placed adjacent to, but not wired to, the inductor coil of the secondary circuit, which is connected to the secondary capacitor. Once the secondary capacitor has built up sufficient electric charge, streamers of electricity (lightning bolts) discharge from it.
Summary: Consider the size, placement, and power requirements of the Tesla coil before you build it. Learn the terminology. Gather the parts you'll need.

In one sentence, describe what the following article is about: for a simple solution. Changing the color of your walls can make a dramatic impact on the way your room looks. Choose a color you love that complements items you know you're going to keep and display, such as a dresser or favorite piece of artwork. Start by moving everything away from the walls and masking the baseboards and ceiling. Apply a coat or 2 of primer and let it dry fully. Then, paint the walls with a roller using long, even strokes. To make your room look more airy and open, choose a light color such as white, gray, or yellow. For a more dramatic effect, you can paint one wall a bold color and the rest a subtle hue. There are tons of cool paints to try, like chalkboard paint or magnetic paint. If you have the time and don't mind putting in the effort, hanging wallpaper adds texture and drama to your walls. Pick a color or pattern you truly love since wallpaper is more difficult to remove or redo than simply painting the walls. Measure your room before purchasing wallpaper and be sure to get a little extra in case of any issues. If your wallpaper is patterned, take care to line up the pattern when you add a new strip! You can use removable wallpaper if you don't want to commit to the print or color permanently. If you want something a little less common, you could cover your walls in shiplap, which is a type of siding composed on horizontal boards. You can use interlocking shiplap boards or even simple 1 by 6in (2.5 by 15.2cm) boards cut to the length of your walls. Work your way from the bottom of the wall to the top. You can do all your walls for a cohesive look or even install shiplap on a single accent wall. Paint the shiplap white for a clean, nautical feel or simply stain the wood for a more natural look.
Summary:
Paint your walls Hang wallpaper to instantly transform your space. Install shiplap to create a fun, nautical feel.
