Just wondering how many people realize that the 60HZ line frequency is eventually tied to this standard ?

This bug caused my Windows PBX to fail.

Actually, I have a time base setback thermostat circa 1930's.

Actually - no it's the FCC (you had me worried) http://www.fcc.gov/complaints BTW - This is just derivative of the toner sales phone calls companies used to get. They would ask you for the model # of your photocopy machine and then send you over priced toner - that they swore you ordered.

I told him to go F%$$%%% himself. and for one of the lower your credit card rates - I asked for his phone number so I could report him to the FCC - that shut him up.

Aka Klipshhorns - Great sound - very very efficient. I was able to bounce my wife's good china with an appropriate Pink Floyd song and 5 watts of power.

They didn't a great job for me in NYC - 8 workers 2 hours to tap (4) 1-1/2-6 holes in a 1/4" steel plate. Or sending a different electrician every day to the job site - so everyone in the union will have work. Or threatening to slice my photographs if I hung them in my trade show booth. Or cutting all of the wires at the fuse panel on a project my grandfather was running. (this is really nasty because you have to re-wire everything).

The worker who made the BMW works in South Carolina and isn't unionized. He/She makes a very good wage and doesn't have to put up with all of the union garbage.

We are an XP shop except for the engineering work stations which are windows 7 - I can't see us going to windows 8 every, our legacy CRM and MRP systems will not work. We still use a Windows 2000 domain- which we are virtualizing. and my workstationis Vista :(

There is nothing really unique about this - the concept has been around since WWII. It just wasn't reliable. Read about Operation Aphrodite. http://en.wikipedia.org/wiki/Operation_Aphrodite

You can passivate stainless steel also to improve it's corrosion properties. But it will rust in salt water. Hard coat anodize (over aluminum) is a better choice - I don't think it will ever degrade.

In Massachusetts businesses can be fined 1,000s of dollars for not having a written data breach plan, but the state is exempt from the rules. A few years back the unemployment office released personal information because of a virus installed on computers used by clients. There was no consequence for the state - and their response was - we can't do anything about it.

Southern California was a different frequency than the rest of the US until the 1930's. The US goverement had to hire clock makers to switch out the AC motors - so the clock would keep time

and for medium size industrial facilities 480V - and yes some but not all are controlled by VFD;s. But you aren't going to run a facility on DC - it' easy and inexpensive to step voltage up and down with a transformer about 1K for a 35HP motor - if you were using dc a dc-dc inverter would not be as efficient, cost effective or (this is a big one) reliable.

I live in "Medfield" and it's a unique town name. Members of the town have been trying to figure out how it got named.
