I get email notifications all the time, but I usually "hang out" here so they are not really needed.

My philosophical take is that zero point quantum mechanical fluctuations create matter and anti-matter from "nothing", and perhaps energy and...

There should be a small fuse (1A or less) on the AC line input, before the TVS. It may be worthwhile to see if there is a DC voltage on the large capacitors,...

Something else to consider is that time itself is affected by both gravity and relativistic velocities. So the few microseconds of the big bang may actually...

I find it fascinating that the cosmic background radiation, supposedly emanating from the singularity of the big bang, appears to be universally distributed...

Many years ago in Junior High School we had moved back into the locker room because a sudden heavy thunderstorm had come up. While waiting, I was leaning...

Anything on the reverse side? It almost has to be a switching supply with the small transformer on the upper right, and in the upper left seems to be...

Years ago (~1975) I found a bubble or blister on the sidewall of a tire on my van. It felt pretty soft and I figured it was just from a slow leak, so...

From his description:



Some of us recommended that when Brian was testing his engine for the edger. Also note that his engine...

I have to admit that I watch TV quite a lot, usually the 11:00 news followed by Colbert and Seth Meyers, and a few of the cop and courtroom dramas. I've...

I have a Ryobi P501 18V 5-1/2" cordless saw which works well enough, but I find it hard to get used to the blade being on the left side. Just seems...

There are no fuses in this motor starter. It seems to have an adjustable electronic overload device which trips the contactor after some combination of...

The motor tag says 28 amps at 230 volts. Locked rotor current during start-up could be 3-4 times that, or close to 100 amps. That will blow an FRS-R-20...

Track not found, or was removed...

Brian, if you could show details of one of your existing carburetors, perhaps some of us could suggest some simple modifications. I think it would be...

Most of the older wall-warts have E-I core transformers in plastic enclosures that plug into wall sockets. They are usually "impedance protected"...

Perhaps there is a valid reason for using a solid 2" diameter nylon rod with a 5/8" shaft tightly attached through a press fit hole bored through...

Note that in my simulation the average voltage (DC component) is 30.57, and the RMS value of the AC component is 16.97. If you compute sqrt( 30.57^2 +...

That sounds like the old B&S lawnmower engines that ran on kerosene.
