Wouldn't the beam have a tendency to pass right through the glass, with little reflection? Wouldn't it be best to have it meet the glass above the critical angle, so it would experience maximum reflection? Of course, the detector would then have to be well away from the laser, and aligning them would be very difficult. And in these days of double and triple glazing, it would be even less viable. > OTOH this simple Soviet invention worked well and had no such issues: > https://en.wikipedia.org/wiki/The_Thing_(listening_device) Thanks for that link.

If I were a coyote, very probably I would. De gustibus non est disputandum. Coyotes are one of the few members of the canis family that eat carrion, as well as fruits, berries and some vegetables.

If the battery has a protection circuit built in, you can tell by the dark band at the negative terminal and a strip up the side to the positive it will trip at something under 3 volts and refuse a charge for safety sake. You can put a very low current limited charge into the to get them up to around 3.2 - 3.4 volts then and only then will a lithium battery charger ( a proper one) attempt to charge it. |

If the watchdog feature lives in the same hardware that it's trying to monitor, then chances are good that if one hangs, so will the other.

"pfjw@aol.com" <pfjw@aol.com>: Nov 16 12:31PM -0800 First a bit on me. Neither of my parents spoke English as a first language (Gaelic & German), nor were they born in the US. Growing up Mid-West, East, South and Mid-Atlantic, and working in various professions and 'jobs' from Janitor to Machinist, and in the US and Middle East, I have seen a bit of the world and experienced a few sorts of people and cultures. Dinner guests in my childhood through teen years included the likes of Dorothy Parker, Helen & Scott Nearing, Hannah Arendt, Felix Morrow, Oscar and Edith Tarcov, Richmond Lattimore, J. Glenn Gray, Peter Drucker and more. Those are the highlights, but I could drop a bunch more names if needed. I get my words from my father, and my humor from my mother. My politics are quite far left of center, but no where near as far as my parents - who were both gun-owning believers in personal responsibility, and felt the world owed them nothing, quite the opposite. I had an aunt in the Irish Post Office, my father was seconded to the OSS during WWII spending most of the war on both sides of the line in Europe. I am married, two step-kids (but I got them very young), four grand-kids, two cats, two dogs. I also consider myself an elitist of the first water - I dislike spending time and effort around ignorance - which I believe can be fixed and is a deliberate choice, never an accident past the age of consent. I also deeply believe the Islamic mandate: Never refuse food, water or shelter together with the Social Contract (best summed up by Karl Marx), although I subscribe to no religion in the belief that religion per-se is largely responsible for much, very nearly all, that is evil in this world - along with any -ism that requires absolute adherence. I am a few months from (technically) retirement age, although I very much enjoy what I am doing and intend to stay at it as long as that enjoyment remains. Due to my wife's and my efforts over the last many years, retirement will be comfortable. It takes a lot to get me to light off on someone. But, anything worth doing is worth doing well - and I try. Some seem to learn and get over it. Some seem to escalate the exchanges beyond banter. I feel like the opposite of the Taxi Driver in the Rutabaga Stories - I can be a much nicer person 'at home' if I vent my spleen in venues such as this one. But, for the record, it ain't nohow personal - nor is any one in the focus worth any actual time, effort or real emotion. I reserve that for friends, family and some very few actual enemies, all now dead (not from my efforts, sadly). Usenet requires the hide of a rhinoceros, a dry sense of humor, and considerable tolerance if it is to be enjoyed. Considerable, not complete. Peter Wieck Melrose Park, PA |

I did describe the cap in my first post. It is a 220 MFD 250 volt cap.I did not name the generator though. It is a Champion model C46540. It has an RV type 120 volt receptacle that used to put out the full 29 or so amps. It also has another 120 volt receptacle that is wired in parallel to the RV receptacle and it is the type that allows either a 15 amp or a 30 amp plug to be used. It also used to put out the full rated amperage. I don't know if it does now. It also has a 240 volt receptacle that I have never used except once just to test it. In your previous post you mentioned using a heat gun to remove the pottying compound. I'll take a look at the links you posted. Thanks, Eric |

Typically, not. This is not liquid-nitrogen cold. The stuff usually cracks into fairly separate pieces, but not explosively. Peter Wieck Melrose Park, PA |

"pfjw@aol.com" <pfjw@aol.com>: Nov 16 11:43AM -0800 Every so often, Phil goes off his meds and starts to act out. Dealing with him at these times is much like nailing Jell-O or peeling raisins. Not very rewarding despite considerable effort. I am not sure what drives him back onto his meds - I expect he mouths off to one-too-many people face-to-face and gets his clock cleaned, or he is found moldering in an ally somewhere. A stint in rehab, and he is fit, once again to be in polite society until the next 'event'. Either way, he has some good knowledge, with the failing that it is neither absolute, entirely accurate or complete. This is true of all of us - however, Phil takes that failing very personally, and deems himself exempt from the consequences. Peter Wieck Melrose Park, PA |
