    Which pole is up?

    While working with unipolar hall-effect senors I checked which face of the bar magnet was the south polar with a compass. The sensor responds to the south magnet but I found that the face that triggered the sensor was the one that the north pointing compass needle pointed to. Looking on...

    Which Equipment for opening&closing coal stove

    I use these to supply hot air from my wood burning furnace to my 'cold' water hybrid heater - the geothermal type. You could just use the motor for your project. You can not make one for 23.88$...

    Which Equipment for opening&closing coal stove

    It's called a damper motor; very old technology. Look for a better buy on Ebay. https://wood-furnaces.net/honeywell-damper-motor-with-terminals-se51000 Connects to your thermostat.

    Coronavirus transmission prevention device.

    In regard to face mask. Say you are walking 10 feet (3 meters) behind someone and they sneeze filling the air with an aerosol. In 2 seconds you will occupy that same space breathing in the aerosol. I believe that a face mask, regardless of what they tell us, would filter the droplets out. Also...

    Questions cable controls snes

    Yes It may dissolve the plastic at the connectors. One can get cable extensions for 8$ and splice them in for new cables perhaps?

    Questions cable controls snes

    Make a small loop in the cable and soak it in acetone as a test; works for me. Save the used acetone to clean paint brushes with.

    British Television?

    two more for you: My dog, not me, watches it to keep him company while I'm at work. The subtitles on my TV are set to French, so I'm not paying a U.K. tax for something I can't read. A note from the same source: More than a quarter million people are fined annually for having unlicensed TVs.

    British Television?

    Some of the best excuses for not pay the license fee from Uncle John's bathroom reader. The best that I can recall: My husband spend 3000 pounds on a huge television so we have no money left to buy a license. A baby magpie (bird) flew into my house and I am to busy feeding it. The baby...

    British Television?

    Greetings from Penn's woods. In Britain I gather one pays a yearly fee on televisions. This goes towards producing programs? My wife just got done watching Father Brown which last only 45 minutes. So there still must be commercials within the programs? What are the fees like on televisions?

    Power shutoffs

    I gather that when you supply power to the grid you are selling your power wholesale and buying it back retail. For 335 KWH I pay 05.1980 cents per KWH or 17.41$ for the electricity. The total bell is 52.36$ or 15.62 cents per KWH. If one sold 100 KWH to the power company at say 3.5 cents...

    Power shutoffs

    If you have solar cells on your roof and you are putting the power onto the grid what happens when the power company shuts off the power as in California? No power for you? If one has an electrical automobile and charged it off the cells one could always steal power from it? Good excuse to buy...
