Avoid dehydration: What's the best to drink in this heat?
Muhendis replied to george's topic in General Topics
Electrolytes are not required to be added to fluid intake. A healthy body is producing them all the time as required. Thats what our kidneys do. Good clean water is all that is needed. I get mine from my RO filter unit at home. -
My New Solar and ESS room
Muhendis replied to Muhendis's topic in Alternative/Renewable Energy Forum
That's not what I said. Granted those are the types I spoke of but they could well be available for FLA's Agreed. The specs. put them on a par with Lithium the down side being, they would be a tad heavy for mobile applications. -
My New Solar and ESS room
Muhendis replied to Muhendis's topic in Alternative/Renewable Energy Forum
The inverter was originally a hybrid thing with auto switch between mains and solar. It didn't have a built in charge controller and I didn't want that anyway. My charge controllers are from SRNE and very reliable unlike the original inverter. After a few years of trouble free running it suddenly stopped. There was no dramatic Bang nor did it flash. No billowing clouds of smoke. It simply stopped. I suspect there was a time sensitive bit of software in the control processor. Spares were not available because "we discontinued that model some years ago". I then did what every body does and redesigned the innards. The only original bits are the transformer and the box. I say I redesigned it but out here in the sticks of Isaan electronic components are not quite as readily obtainable as in Bristol UK where I came from. So I hunted around and found a few bits and pieces in China courtesy of Alibaba which would be more than adequate to do the job of converting DC to a switched power signal to drive the transformer. Wonderfull. I now have a low frequency inverter with an output of 8KW and electronics capable of 12KW. I think I should mention I also have a very elderly degree in electronic engineering. Yep. My wife thinks I'm brilliant but that's another matter entirely. Batteries are indeed heavy. I had a couple of kids in the village do the lifting for me. The frame is steel rectangular tube 75 x 35 x 1.5mm. according to calcs it will deflect in the middle by not more than 1.5mm with a distributed load. Bus bars are copper 15 x 5mm which gives me 75mm² which is ample 🙂 for all the mega amps They have to handle. The joints are vasalined which works a treat. Polishing? What on earth for? My LC's do not give off any gas. Efficiency? Don't care. It gives me what I want all day and all night too. Watch this space for the upcoming solar panel change. Mine are knackered after 13 years from a dubious source. -
My New Solar and ESS room
Muhendis replied to Muhendis's topic in Alternative/Renewable Energy Forum
FLA's (flooded lead acid's) are extremely robust but need a lot of TLC because they are thirsty. I had an auto watering system with mine and made my own deionised water. Their life expectancy is in the region of 3 years with a depth of discharge not greater than 35% or thereabouts. FLA's are considerably more temperature sensitive than LC's (lead carbons) For every 10°C temperature rise above 25°C the battery life expectancy is halved. Whereas LC's have a much better tolerance and won't start to degrade significantly until the ambient gets above 30°C Economically speaking, if you consider the relative price difference between FLA's and VRLA with lead carbon the price is not that much greater. VRLA's with lead carbon have a design life of 10 years Gel's with lead carbon have a design life of 20 years What this means is the battery life in float/standby mode. -

China. My lead carbons are Gel type as opposed to VRLA The difference is a lot more than subtle as is the price. If you have a look around Google there are now many suppliers of this technology. When I got mine there were very few. I went direct to a manufacturer and did my own import using an extremely helpful agent in Bangkok port. -
Phuket hotel evicts foreigner who threatened taxi driver with knives
Muhendis replied to webfact's topic in Phuket News
I'll see what I can arrange for you. -
Many years ago I was paid in cash on a Friday afternoon. I could take some of my cash to the post office and put it into a savings account which would earn 4½% Banks would be trying their hardest to get me to deposit my cash with them but their interest rates were less than the Post office (and building societies for that matter). Now here we are in this (wonderfull?) digital money age. Employers pay wages direct into bank accounts. We are asked to use prompt pay or maybe debit cards to pay for goods. Interest on savings is virtually nonexistent. (the banks borrow our money for free) The control we once had over our money, is gone and that has happened in the guise of progress and ease of giving your money to someone else. The speed of returning money when there has been an error is much slower in this digital world than the speed of taking it from us.

Foreigners and their overseas income: what next?
Muhendis replied to webfact's topic in Thailand News
Banks will be obliged to pass on information to the revenue department relating to monies received from offshore. The revenue department is thus expecting information to come to them rather than they go looking for it. -
Thai doctor in Swiss expat case says she has ‘stress’
Muhendis replied to snoop1130's topic in Phuket News
Well why not? If Thaksin can do it so can all others. -
oh bum. I've been sussed.

Yeah. I can appreciate your point. Why spend money when you are thinking of dieing before payback time comes around. How old are you if you don't mind me asking? I am well into my late 70's and still enjoying technological challenges. My wife keeps telling me I should live 'till I'm 125 so I go for it and stuff my kids inheritances.

Aircon is a power guzzling luxury (or maybe not so much of a luxury). I would suggest that, at current prices, solar technology would give you a payback time which would be well worth the capital outlay. Mind you, it would be more economical to run your AC at a sensible temperature in the region of 27ºC in the bedroom and 30ºC in the lounge and also change to inverter technology if you don't already have it.

"The electric bill is bad enough at 26c" Don't you have solar off grid like everyone else. Ah! Perhaps you live in a condo. Tough

Some machines like computers, microwave ovens and washing machines have filters which seem designed to leak a little bit. This is normal. Having leakage with all individual breakers off may be indicative of a swapped live neutral wire

Foreigner Allegedly on Drugs Causes Ruckus in Pattaya

Yep! Maruana marguana weed makes you happy to agree with all. Alcohol makes you bludgeon people into agreement. -

Good thinking. But, over the years. As more electric bikes are used petrol will become scarce and expensive. More people will have solar power which makes for cheaper motoring. Electric bikes, with few moving parts will become much less costly to buy than petrol bikes.

Thai Officials Announce "Innovative" Expat Health Measure
Muhendis replied to webfact's topic in Thailand News
In the accompanying picture, the masks being handed out are surgical masks. Surgical masks are worn to prevent the wearer transmitting their germs etc. They should be giving out N95 masks to protect the valuable tourists/farang. -
What a load of fuss and bother some people have had. I simply presented my new passport together with the old one to immigration at Buriram. Insisted, twice, that it is a free service. 10 minutes later was presented my newly stamped (marriage extension) passport and went home. It is a free service and no documents required
