  1. Has someone been snooping around my house? 😉 I used a step-up/step-down transformer when running the modified square wave or the Reliable 3k sine wave just to make starting the fridge easier. Never tried it with the U-Power ( PJ ) one to see what would happen. As the transformer is a toroidal one it didn't care about the wave form in.

    Hey Sid!

    Another job for your Linux skills. Hack the code to get the user password. 😜
  3. So the largest US nuke plant, not the world's. I live within 15 miles of the US's 6th largest Nuke plant and it soon will be the 3rd largest nuke plant in the US if they get on with the construction. Yours does have another distinction, the only one cooled by treated sewage.😉
  4. You live in Japan?
  5. Take the second highest ADU and double it and that is ours. Comes out to about 8 dollars a day though.
  6. So does that mean I need to ship it back?
  7. I wonder if I should try my Warp Server Beta in one of my laptops. 😁
  8. I hope you have fuses or breakers between the inverter and the point where you pull off the power from. Because the Amperage going to the inverter could be the sum of all the other breakers/fuses combined. If you had (4 ) 150 Amp breakers from your batteries to your buss, you could have 600+ Amps on it before it would trip them out and that would burn up an inverter in a hurry if you didn't have a 250 or 300 Amp protective device at the start of that line. That being with 24 Volts. If you were on 48VDC, then you would want a 125 or 150 Amp unit to protect it. 125Amps X 48VDC = 6000 Watts 150Amps X 48VDC = 7200 which is the point where you would not want to run for long even though the GS 6K would not mind much. I'm on 24VDC so I put in (2) 250 Amp ones on the lines to the inverter from where the battery banks combine. That should take it to 6Kand protect it well.
  9. Hey, you are missing a few cases of Broken Windows. WFWG 3.11 was a good one until they broke just about everything in Lose 95. And then there was Windows ME and Bob. And what about Win 2K Pro which actually worked decent.
  10. Hey now, I play M$ Solitaire on my Samsung G-10. And where's the OS/2 for banking?
  11. And by the way, while the car was rated by Amtrak for speeds not to exceed 110MPH, on one stretch of the NEC, near Philly, we clocked in on the GPS at 115MPH and was also clocked the old fashion way, by RR approved watch.
  12. http://s3.amazonaws.com/rrpa_photos/102687/cs09nbrcocogrove.jpg The link will take you to a picture of the car when owned by my friend and lawyer.
  13. In between the ice bunker designs and the DC units was a third type that use pumps and fans. It was steam ejector A/C. Where the steam drew a vacuum on a water tank and the evaporation/boiling of the water gave up the heat. The chilled water then, like in the ice bunker style was pumped up to the radiator unit in the ceiling where the fan blew air into the rest of the car. Ice Bunker A/C was very good at cooling a car down quick as by the time the water had made two passes in the system it had cooled down to 34°. It could take a car in 90° temps inside and out and cool it to 70° in about 15 minutes. It also was very good at pulling the humidity out of the air such that the unit needed two 3/4" drains to dump it. Excess water to the needs of the system was dumped automatically when it was was coming back from the coil before being pumped over the ice again. The units were rated at 2 tons per day and the bunkers held 1400 pounds at a time each. The steam vacuum systems required add in water all the time to make up for the use. So it came out of the cars water tanks. Almost all of the cars built in the 40s had Ice bunker A/C while late in the 40s they started the switch to mechanical A/C. In some cases, simply sliding units into the bunkers to replace the ice and still using the rest of the systems already in use. All of the units used Freon 12. Cars that ran in the SW of the US had started using DC A/C in the middle 1930s. The car my friend had was built in 1936 for the Santa Fe Railroad and had DC A/C. It got AC A/C when it was rebuilt to meet Amtrak requirements in 1994-96. It is the oldest Stainless Steel car that meets those specs and one of the earliest Stainless cars that were interchange capable instead of units like the tilt trains are.
  14. Back in the good old days( pre Amtrak HEP ) railroad cars used 32, 64, or 110 VDC to run the cars A/C. When Head End Power became available and the cables mandated for any cars used on Amtrak trains, most owners converted to 230 VAC 3 phase units. From 1951 to about 1960, the crew car for the communications crew of the Communication Car, Presidential had ice bunker A/C cooling with just 32VDC fans and pumps ( same as would be found in the Presidential Pullman ) but had 32VDC freezers and refrigerator. The Communications car itself had 32VDC A/C. It needed it as just the lights in the Comm room would generate a lot of heat. And then you had the two transmitters and the receivers in the car. Those transmitters generated a lot of heat as they were tube type units. Those same units however were still in use into the 90s as they were the only things that could be guarantied to work under many conditions. So while the RRs switched to AC A/C units, many are learning of the benefits of having DC units. Thing is, I don't know of any that are sealed units. All were motor and compressor units which sooner or later will leak Freon at the seal of the shaft.
  15. While you are at it, make it so that it can have its own Starlink account. 😉
  16. It is running fine. Just one of these days need to find out why it will not take any kind of input or work with my WiFi in the shed. But then the MSB units won't talk to me either. Still think there needs to be a cover over the screen and buttons to keep out dust/dirt, dog hair, Gecko droppings.................................... Darn Tokay scared the heck out of me the other night as it sounded off right above my head. And unless you turn up the volume full blast, it comes nowhere near how loud they get.
  17. Ha ha ha.🤣 You don't know what some of us can print with a 3-D printer, crazy glue, and a plastic melt pen.
  18. That's what the screw holes are for. Anchoring it down........................ wait, mine isn't because it is sitting on a shelf and the cables prevent it from moving much. One of these days I'll put a couple of screws in the holes into the shelf. But after 600 hours of running, it hasn't moved yet.
  19. I used the measurements of the unit sitting here as shipped.😉 And 65 lbs was the shipping weight which way exceeds what I'm supposed to be lifting. By 45lbs.
  20. That first one is a 12Volt one anyways. The ones I use are either Bussmann 42VDC units or these.
  21. If it was the Wuhan Flu, it might have been the second or third go at it. Being of the Type O blood group supposedly makes one have milder affects and I had this a couple times last year. Need an anti-bodies test. Dropping the Voltage, I recalibrated mine and so It may never show what yours did but mine runs mostly 121 and 122 Volts on my meters on the split phase. Line 2 is always 1 Volt higher than L1 to N or equal. Never lower even if loaded.
  22. Now showing 317 hours of use and so far the only glitch has been the one No CPU Comms message. Didn't get much use the last 5 days as I have been down with something. Will know tomorrow if possible it was a mild Covid attack. Or some other flu bug.
  23. It shouldn't but it would load the transformer differently. Center tapped transformers can have different characteristics when one side is loaded vs if both sides are loaded. In you case, your transformer is a single doubled output L1 & L2. In my case, it is a single phase across L1 and L2 but center tapped. With light loaded L2-N, the magnetics of the transformer would be different than if operated as a single phase only.
  24. Your 3-D printer shouldn't care, at least mine doesn't. If it was going to do something, I would have thought that it would have shown up in a 4 hour run.
