The Closet Method: A walk-in closet is typically the most soundproof environment you will find in your home, thanks to the small size, lack of windows and hanging clothes. If you have to record instruments or voice-over with absolutely zero prep time, use the closet as your best bet. Ob...
I have used homemade gimmick capacitor and even double-sided PCB as a capacitor for Cy and they all got hot at high power. Silver mica capacitors run much cooler and they do make a small difference in the output power, so I
It's no surprise that guitarists quickly began looking for ways to pump up their sound. The very first guitar effects were built into instruments themselves. In the 1930s, Rickenbacker made a clunky Vibrola Spanish guitar with motorized pulleys that jiggled the bridge to create a vibrato effec...
The easiest way to do this is with another magnet -- stroke the magnet along the needle 10 or 20 times as shown below. If you are having trouble finding a magnet around the house, two possible sources include a can opener and an electromagnet that you make yourself (see How ...

The second nail is important because it keeps the strip of metal from pulling too far away from the electromagnet. It also serves to make a clicking sound when the strip of metal is released by the magnet and moves upward. To complete the telegraph set, simply connect the key, batteries,...
But assembling a homemade system is a great exercise for understanding how analog surround sound works in the first place. In the 1990s, a new kind of surround sound started popping up in theaters, and since then it has been gradually eclipsing the standard 4-2-4 approach. In the next ...
to this head are quite thin. i doubt they could take a current of more than 1 mamp. the platter is about 0.1 mm from the head. with these crazy assumptions, i can calculate the magnetic field from this small electromagnet. if you have a small loop of wire with current, the magnetic ...
