I collected the insurance and here I am."<p>"That's a coincidence," says the second one. "Same thing happened to me. A flood came along and wiped out my...

Re: variance euqation?

In the right hand term in the TOP equation shown in the<p> http://user52.starbeta.org/others/question.doc <p>link, you are taking the sum of the indexed values from i= 1 to i = n, and then dividing by n to get the average value of x. This would be proper.<p>In the right hand term in the BOTTOM equat...

Re: since somone had a ultrasonic question....

Same effect as with ultrasonic room humidifiers. I've often wondered if the "dusting effect" is due more to collection and settling of dust particles on the water droplets in the air rather than solute load in the supplied water. Anyone know?

Re: How About an Ultrasonic Pill Splitter?

The shock advocates seem to have the right idea. I've found that merely pushing the manual pill cutter blade down tends to crush, while a sharp rap tends to split the pill evenly. Centering the pill in the little v-groove is important, also. Not 100% perfect, but a sharp rap sure beats just pushing ...

Re: hot surface ignitor

Don't experiment with furnaces unless you live next to a fire house.<p>Since we know these ignitors are fairly standard devices, but are fragile and consumable, the solution is to buy proper spares in advance.<p>The heating circuitry is designed for the silicon carbide. You could probably jury-rig s...

Re: appliance without batteries

Pardon my ignorance, but how come the word-wrap on this topic is about two of my screens wide?<p>Any suggestions to cure this?<p>A UBB or HTML tag to change the whole topic on my screen?<p>I don't want to sidetrack this interesting topic, but if someone can help in one post, it would be nice.

Re: radio controlled relay

OK. I just didn't think IR would do it that far in adverse atmospheres with reasonable powers. Hm... <p>...and speaking of power:<p>http://205.243.100.155/frames/longarc.htm#Disconnect<p>This link might scare some people who only deal with TTL levels. ;) <p>Make sure your sound is on.
