Sometimes Back up Generators create serious problems for IT professionals. Sometimes the voltage drops so low and the current is so high that power supply PC boards actually burn up do to massive current.
What products or product deals with this issue specifically. If the voltage drops so low or is too high, it kills the power, and not allow it through. When the power becomes stable it allows the power to go through. What is this product?

Look at this website. http://www.electronics-lab.com/projects/power/015/index.html Now I'm wondering why have the large and small caps at the input and output of the regulator. I understand that the caps help stabilize the voltage at the regulator, to keep it from oscillating, but why have a relative large and a relatively low capacitance? Since capacitors in parallel add, the outputs of the regulators essentially have 101uF of capacitance. Why not just put a 200uF cap there and call it a day? Same with the input to the regulator. There's a 2200uF in parallel with a 1uF, oooooo, 2201uF!! Why not just put a 3000uF there if you want more than 2200uF?

I want to create my own custom lighting in my vehicle. Mostly I want strobe lights because I am a DOT employee and frequently work on the side of the roadway or assist straded motorists. I would like to use low power, high output LED to create the strobing effect. Where can I get/purchase these at the lowest possible cost and best possible value?

....about what really happened to the steel? I would think if you build a building like the WTC, you would over-build the specs just to make sure.
