I got a bit irritated by the claims for a particular device that is supposed to let one electrolyze water at a rate 1000 times greater than physics says is possible. The article, the D9.pdf - http://pesn.com/2007/09/29/9500450_B...r_Plans/d9.pdf- is full is nonsensical claims. The electronics...

I'm a relative newbie to electronics. My interest is in audio tube amplifiers and tube guitar amplifiers. Back in the days I built a Dynaco PAT5-BiFet and 416 and now wish I had gone for Dynaco's tube amps instead. This is pretty much the limit of my experience. (I have some bugs in the...

I'm going to use this space to link to projects I am currently working on, or have shelved with the intention of getting back to them (there are several in that catagory). I tend to jump around a bit, but you notice I'm trying to organize my blogs as a unit, a minibook if you will. If you wish...

i love Science because its teaches me about life and its ways. it also teaches me why some somethings happen and why they are the way they are. Science is a discipline, it teaches you things you don't know about yourself like... What your are made of, How your body gets energy, Why we eat food...

A chaotic neutral character follows his whims. He is an individualist first and last. He values his own liberty but doesn't strive to protect others' freedom. He avoids authority, resents restrictions, and challenges traditions. A chaotic neutral character does not intentionally disrupt...

Last time, I mentioned Chief M., an abusive type so bad that we got a sympathy card from his last command, and the "fun" the display techs had with him. I was also put off by the man, so I had to butt heads when it seemed appropriate (daily). He always came in at the same time, so I could be...

Well, it has been some time. My advice is to never get involved in a patenting process. It eats time with no guarantee of any success. Some years ago while I was still in the Navy, I was at a shore duty station. This was pure luck, as it came after my 2 1/2 years of training. I would have...

Last night Windows Vista SP1 came through on Windows Update following an update to my sound card driver (SP1 had been held off due to a selection of conflicting drivers). Having heard some good things about SP1 I installed it and thus far everything is fine. One thing I did notice was that by...

In the accompanying attachment, a circuit is analyzed first with Kirchhoff's Current Law (KCL) and then with Millman's Theorem. The purpose is to permit the reader to compare the two techniques when applied to the identical circuit problem. Once again, I welcome any comments or suggestions on...
