  1. This thread have some great advices: http://www.scienceforums.net/topic/54213-nicotine-tapering-method-to-quit-smoking/
  2. I am sorry, but I can't give you any guarantees about your inverter's output, as i don't have any experience with it, however at my work we have lots of computers running on UPS power supplies to protect them from surges and brownouts from our mains. The charger in the UPS could still be connected to the battery even if the UPS is disconnected from the mains, if it is powerless it should not interfere with another charger, but I need to stress that I can't give any guarantee that connecting a second charger won't harm the UPS or the charger. EDIT: If you are going to try this you n
  3. If it is a good inverter then it will not destroy your appliances, and if you already have used it for longer durations without mishaps then I don't think it will be more harmful for your equipment if you were to always use it. The problem with another separate charger is when your mains voltage goes above 170 VAC and the UPS also tries to charge the battery, then there will be two chargers competing on the battery voltage and if they don't work together one or both could be destroyed. If the UPS allows a separate charger and you can find a charger that is compatible with it, then it w
  4. If you want 220 VAC independent of input voltage then you need some kind of inverter. It have to automatically switch from bypass mode when voltage drops to low and start to supply 220 VAC but still be able to continue charging its battery or capacitors in the intermediate circuit with the low input voltage. (Or if you have very long periods with low voltage then you could have a separate charger and inverter and manually turn them on when they are needed.) Much like your UPS but with an intermediate mode where it supplies enhanced power while still charging the battery from the low
  5. There is nothing in that device that will make it able to output exactly 220 VAC. It has three stages, adding a low voltage to input, removing a low voltage from input or forwarding input to output. (Also if the input voltage goes way too low the relays will not be able to activate and it can only forward input to output.) It is likely that you have changed the settings for the two potentiometers such that the two relays no longer can activate as they should. Finding the correct settings for the potentiometers without access to adjustable voltage is not going to be easy and since
  6. Yes, but my view of a flat Earth is the old fashioned with a fixed Earth and an absolute up and down. If they believe that the flat Earth is like a spinning coin orbiting the Sun and has the Moon as an orbiting companion, then they have already come very far from the old model and the final step to a spherical Earth is small.
  7. Thank you for clearing up the misunderstanding.
  8. The front implies that the device can handle 90 to 250 VAC but it does not specifically guarantee that it will output 220 VAC from 90 VAC. From the image it looks more like there is one indicator light that shows that the input is between this level and one indicator that shows when the output is around 220 VAC. Did you take note on how they where located so that you can return them to the position the second repairman placed them in? How do you know it gives power if the electric iron didn't work? Good. What voltage did they show with the electric iron connected?
  9. During a partial lunar eclipse we can look up and see the curved shadow of Earth on the Moon: A lunar eclipse occurs in two regions, an outer penumbral shadow where the sunlight is dimmed, and an inner umbral shadow, where much dimmer sunlight only exists by refraction through the Earth's atmosphere, leaving a red color. This can be seen in different exposures of a partial lunar eclipse, for example here with exposures of 1/80, 2/5, and 2 seconds. https://en.wikipedia.org/wiki/Lunar_eclipse Maybe you and your friend can see it yourselves on September 28: A total lunar eclip
  10. Well, speaking for myself, I can personally confirm that gravity exists and see with my own eyes how the Moon is shaped, logically it is gravity that holds all the parts of a natural celestial object together, thus the Earth has to be round too.
  11. If he believes in a world wide conspiracy that hides the truth of a flat Earth, then why do you think he would trust personal photos from strangers on the internet?
  12. This thread is getting slightly out of hand, first we need to understand and solve the issue with the stabilizer before we can move on to other equipment the OP want to connect to it. ----- I have only looked at a few of the photos since I have serious trouble with dropbox from work and this seems to be a very simple device only able to stabilize voltage above around 180-190 VAC and up to 250-260 VAC with a maximum current of 10 amperes. There is no pulse wide modulation, switching nor capacitor filtering in this unit. I guess it has a low voltage transformer that probably has a
  13. That would depend on the potential of the circuit and the charge of the capacitor at the end of the wires. If the battery is connected long enough for the potential to even out and if the battery later is reconnected with the polarity switched, then L3 will light up. For the second circuit the capacitor is almost entirely removed and to small to light up L3.
  14. Well yes, sure they could probably compete or even be considered superior in scientific knowledge and they could likely teach the caveman some useful stuff. But that was not the question, the question is if they can be trusted on everything they claim knowledge of. Should we take their word for it and accept whatever thay say without questioning it, just because they step out from a fancy ride? You seem to argue that anyone with "a functional interstellar spaceship" is all-knowing, infallible and only wants the best for us. I think 'they' could be wrong about many things, make m
  15. A caveman would probably learn a lot from listening to a former Resident Expert at SFN, but how much not relevant crap could he be fed if he would meet a random proponent from our Speculations section?
