  1. Is Sodsong related to Johnson by any chance?
  2. Would that be Windows or would that be Linux............ Never seen a battery coffee machine before. Wonder what would happen to the battery if the coffee got too hot. Never a problem with sodium cells. I nearly got a load of sodium batteries for my Solar many years ago but the Canadian company went bust first. You can get 'em here https://bridex.fujielectric.com/salt-water-battery
  3. The rusty old wreck is more compulsive click bait.
  4. Soon we will have multitasking batteries.
  5. The country could adopt something like the UK national insurance system. The ageing population and reducing birth rate may make that a bit tricky though. A reducing birth rate isn't so bad because, although the number of contributors to the system becomes fewer, so does the number of recipients.
  6. Yeah, Grondfos is the Rolls Royce of pumps but I swapped mine to Mitsubishi 350W because the Grondfos was 1100W and didn't 'arf use my electric. The Mitsubishi does the job equally well.
  7. Sounds to me like a motor problem. If you can check the running current (electric that is) and compare it with the rating plate power this will give a good indication of state of the motor. It is quite possible that a 10 year old pump will suffer from stiff bearings and so will be working harder. Another test for this is to turn the pump motor by hand. It should turn easily. To do this there is usually a screwdriver slot in the accessible end of the shaft. If the motor does turn easily then it is quite likely to be an electrical problem in the motor windings. As above you should be able to confirm by checking the motor current. You will need to calculate what it should be from the simple formula of Watts/Volts = Amps so, for example, a 300 Watt motor in a 220 Volt supply would be 300/220 = 1.36 Amps under normal running conditions. Measuring this current is best done with an AC current clamp meter around the live wire where it is accessible in the consumer unit. Just make sure there is nothing else running from that particular mcb at the time.
  8. Oh come on please lets stop sucking around. Happy New Year
  9. It..... Have I won a prize?
  10. Well said and Happy New Year
  11. With some equipment like an oven for example, there can be a problem with live and neutral reversed. The element switches are all on the live side so a reversed L-N would mean switching on the neutral side.
  12. All this newfangled technology is a bit daunting so I though I would take a look around google and this is what I found:- https://pattaya-pages.com/pea-smart-plus-app-for-remotely-checking-electricity-meter-readings-electricity-consumption-statistics-by-hour-day-and-month-and-much-more/#2 It may be totally unrelated to the digital meter problem but on the other hand............
  13. Here is the lab report so make of it what you will. Bore hole Water Analysis 2018.pdf
  14. Can we settle for Calcium carbonate please?
  15. Thanks for spotting typo. CaCo3 owes it's existence to the huge amounts of gypsum 51 metres below ground. It was coming in at over 2000 ppm. Yes there certainly was. Note my comment "It gets to behave like a battery."
  16. Yep. Water heaters are resistive so don't care if they get AC or DC. In fact DC should be more efficient. My system is a home made flat panel on an outhouse sloping roof. The panel is a number of 15mm vertical copper pipes between 22mm input/output horizontal pipes. 15mm pipes have sheets of aluminium attached for heat capture. All this is mounted in a wood frame with polycarbonate cover Below, in the outhouse, there is a small circulating pump powered by a similarly small solar panel and a 200 litre insulated tank for storage. Water temperature varies between OUCH BLOODY HELL! and lukewarm depending on time of year and weather. At the moment it's cold here and there's been one day with a fair bit of cloud but I still got lukewarm. As it's a direct system I have to watchout for minerals in the water. Bore hole water is way over the top with CaCo4. That stuff plays havoc with copper and creates problems with dissimilar metals of the storage tank (stainless) and the copper pipes/brass fittings. It gets to behave like a battery. I stopped using the borehole a few years ago and use well filtered surface well water which is so soft the soap lasts forever. Being as how I'm a cheap Charley that's a plus. Cost was about a fiver 'cause it was built in the UK 11 years ago hence the copper pipe sizes. It's a fun project and does what it says on the tin so to speak.
  17. 6. Because it's always nice to see those nice, friendly immigration people. 7. What else should we do with our time if no longer tied to the treadmill of work.
  18. It's a male chauvinistic thing. The brainless alpha's are like that the world over. I hope the lady gets her justice.
  19. In the UK trains get stopped by leaves on the track. In Thailand, it's dirt on the track.
  20. Taxi from Don Muong to Ekamai Bus from Ekamai to Pattaya
  21. A bit of self deprecation does us good from time to time.....
  22. I had many very good experiences with Lazada up until a few years ago when they started their own delivery company. That's when it all went pear shaped for me. I would imagine all those problems are long gone by now but I'm a Shopee man now.
  23. I know someone who was in the same position of wanting to build straight away. He had piles put in and built his house on them. His house was completed in a few months from land purchase and the land was previously rice farm. The idea of using a vibrating roller may not achieve what you would expect. The road from the village to my house is testament to that.
