Probably way too hard to get the wires attached to the male part of a BNC. I sort of thought phono plug but that would leave the male part where it could short out to something when unplugged if the male was hooked to the power supply. Ebay has lots of the coaxial type power plugs and sockets for a few bucks. Just buy a matching set so they will fit without any problems. |
N_Cook <diverse@tcp.co.uk>: Dec 02 02:33PM L'esprit d'escalier. Next time I'd remove the speaker connector on the main pcb, and solder in the sp wires and add solderable/desolderable tags on the rear outlet pcb, to give some space for the replacement components. So can get some air through the replacement components rather than just around, as well as the same simple baffle to direct air into that backwater area. Did use long W/W Rs rather than the squat ones that were in there, so at least the tops will be in moving air. Added a simple LED monitor , requiring 25V pk-pk 4KHz or 10 V pk-pk 40KHz and about 4V of 200KHz before the LED is visible in a dark room, wiht instructions to owner to ignore any pulsing with notes, just a continuous LED would mean a problem in the making. |

I find most things are OK if I add 25% to the cooking time. For example, if it says 3 minutes I use 3:45. BTW, some people have said that if I got a new microwave, it would probably fail before the old one. [snip] -- 24 days until the winter celebration (Sunday December 25, 2016 12:00:00 AM for 1 day).

Maybe, we have one that was manufactured in 1983, still works fine, but we have two, and this one is not used as much. Mikek |
micky <NONONOmisc07@bigfoot.com>: Dec 01 11:03PM -0500 In sci.electronics.repair, on Wed, 30 Nov 2016 23:20:17 -0500, Mike >+1, You are the only one who did not lambast the OP for using the term >'warm up' to mean 'cause the ambient MW intensity to reach its operational >range'. Just for the record, I consciously used the phrase, because it reminds me of simpler times, harmed only by the extra time it took to turn on the radio or tv. (In the movies, sometimes they would turn something on and it woudl start immediately. I did stay at a hotel once 8 years ago that was also operating in the 30's and it still had the remote speaker/channel selector for the central radio it used then. Each room had one and the patron could swtich between two or three stations, and adjust the volume, so when you turned it on, it went on immediately. Unfortunately, the hotel finally closed.) >When I am judging time for extremely small loads (like softening butter >without liquifying it), I allow 4 seconds for my oven. I'm pretty sure mine is less tnan 4 seconds becuase I really have used 7 seconds and found noticeable heating, more than I think 3 seconds would have done, based on the prior 10 seconds. BTW, if you get one of those slabs of chocolate chip cookies, precut, they say to cook them in a hot oven of course, but 37 seconds per square does a good job. Not like baked, but like a differen4 recipe. Another reason to know the startup time is if I make two of them, it only has to start-up once, so it needs less than twice the time, but the instructions already say less than twice the time, and their differential is greater than 4 seconds. I think there is some reason for that other than start-up, warm-up time. |

Is there a way to come out of the VGA jack on the back of my laptop and somehow end up with composite or S video out? I tried an adapter that my son said he had used to do this in the past. It plugs into the RGB jack in the back and it has two short cables out of it. One has an RCA female jack on the end of it and the other has an S video female. I didn't try S but although I can get an image on my composite monitor you can see that there is more than one image and it's out of sync. I tried adjusting the display settings and that seems to put the frequency way off. I used to have a video board on an old DOS computer that had an RCA jack on it and it was very handy. Is this still possible to do? I think that I read somewhere that anything ten ears older or less should be able to support this. I don't know how old my laptop is but i don't think that it's over ten years. Thanks, Lenny > I thought "perpetual motion" was a theoretical quantity, kind of like the square root of -1.

ohger1s@gmail.com: Dec 01 10:33AM -0800 > Now, exactly what is wrong with: > From each according to his abilities. > To each according to his needs. Because it doesn't work.. never has and it never will. It's a nice theory, but human beings as a group are not inherently altruistic. Humans will do as little as they can and take whatever they can get away with. It's been that way in every society that ever existed. The Romans knew this and therefore *chained* the rowers to the boat. Motivation. And while self-preservation is a big motivator, money is just as good. Most technological or medical breakthroughs happened in capitalistic societies. And, in general, the more you give to a needy person, the more he'll need. Why is it that the more money we spend on the poor the more poor are created? People that need help should be helped, but this welfare state we've created has created generations of enabled folks who have no hope, no skill, and certainly no motivation to improve their lot. And if I were more suspicious, I might be inclined to believe that the party that "advocates" most for the poor is just keeping them enslaved and buying their votes. |
