Your Saviour

I have 5 PCs and want an audio file to start playing at exactly the same time on each computer.

It's a 10 hr recording of an air raid siren (off utube) and I want it screaming out of each PC at the same time, and synchronized so that it sounds like one, large distress signal.

I am guessing that I would need to synchronize each PC's clock to NIST or other accurate source, and then have software time the start of the file which will be on each PC.

Can anyone point me to software that can do that or explain an other way to do this? Thanks.

I'll be Googling this in the meantime, but I hope the geeks out there can help me.

Does anyone have a guaranteed way to loosen brake bleeder nipples that have been untouched for 8 years? Here's what I'm already trying:

- Scraped away all dirt around thread, applied PB Blaster several times over several days.

- Tapped with small hammer, again soaking with PB Blaster.

- Will buy a micro-torch to heat bleed screw, then PB again.

Before buying new rear cylinders I will use my method of last resort: bleeding through the piston seal. I have a very small, flat, strip of spring steel that I insert into the gap between the piston and the cylinder wall. While someone gently presses the brake pedal, I push the top-most part of the the piston seal inward with the thin strip. This allow air and fluid to bleed out. One has to be careful not to damage the seal though. This method requires removing the shoes, springs and piston dust covers.

Another way is to hold the lowermost piston inside the cylinder, preventing it from exiting, and allowing the uppermost piston to completely exit the cylinder (as a helper is pressing down the brake pedal), letting trapped air out. One has to keep the upper piston pressed against the cylinder bore just hard enough to prevent it from popping out completely, but loosely enough to let air out.
