But if the OP is indeed fluent, then he/she will be bored out of their mind. It is a visa requirement that the student attends the course.

There that's fixed. Some people are saying that the ruling party fears Pite and his pals. I don't think fear comes into it. The ruling party and the military are way too arrogant to be bothered with fear. They know they can get whatever they want.

Not so good in a country full of termites.

Will thus mans death change anything? No. Of course it won't. Villagers will simply regard it as his bad fortune and carry on as normal.

Yes. His is looking pretty good too don't you think?

Bring back the Kettering system. Clean the points. Change the coil. Change the "condenser". Spray anti condensation stuff all over the place. Crank the engine with the starting handle. Ah. Yes. Those were the days.

ALT....CTRL....DEL.

"A driver told of how he was trapped behind the wheel of his electric car when it sped up to 90mph and would not respond to him pressing the brakes." Full story here: https://www.standard.co.uk/news/uk/electric-car-motorway-driver-nathan-owen-jaguar-ipace-b1143726.html The fact that the car uses batteries is not relevant in my opinion. I think the blame lies with the computer. One thing is certain. Jaguar who have discontinued that particular model will take a big hit and maybe MG also. Nobody wants to be in a car that suddenly decides to do it's own thing.

Dunno. But I don't have to drive for 5+ hours to get to the London Steak. Pattaya lost its "charm" when the Pig 'N Whistle went.

Clayton also has daughters in that age group who occasionally put in an appearance.

London Steak has both Thai and Western food and is frequented by as many Thais as westerners. There is a choice between air conditioned or non-air conditioned seating. The menu is huge. The western menu has vegetarian as well as all the usual choices of fish, pork, chicken and, of course different steaks. All foods are cooked well and generous portions. No intrusive loud music. Waitresses do their job well and for those that like such things they all have nice legs. Wine is plentiful. The restaurateur, Clayton, goes out of his way to take care of his customers.

You've never quite made it to the London Steak then.

So give her the brush and let her get on with it

Quite cool by the seaside then. Here in Buriram it's 38°C but the light coating of dust from the sugar cane lorries as they rumble past makes it seem hotter.

So Bobthegimp rode all the way from Pattaya to Paddy's Irish Bar in Buriram and finds it refreshing? A change is as good as a rest....... Takes all sorts I suppose

Thanks. Already on it but I am looking at 340W for preference because they are smaller for manhandling and less of a problem if one is not so good.

You sound like my wife You are quite right about normal lead acid batteries but I am talking about lead carbon batteries Please note I have already mentioned they need a gentle charge the first time around. After that they can be charged similarly to a capacitor which is what they are in some respects. Agreed This is referred to as charge acceptance But I am not talking about lead acid. Charge acceptance for a lead carbon battery is similar to a LiFePO4 which is much much better than lead acid. This is due to the capacitive effect of the additional carbon/graphene rather than the chemical change in the lead/lead sulphate of the lead acid battery. If you try to charge a lead acid battery too quickly it will cook and enjoy a slightly more violent but shorter life.

Please note my earlier comments re. 30% DoD Well done you have won the top prise. The less they are discharged, the longer they will live. Having said that my solar panels are well over 10 years old and I do have other things to do with whatever power they can give as well as charge batteries. I will be getting some shiny new panels in the near future.

A lead acid battery will suffer from sulfation if it is only partially charged. Lead carbon batteries, on the other hand, will not suffer from sulfation to anything like the same extent. Charge cycles for lead carbon are the same as for lead acid ie there is a constant current phase followed by a constant voltage phase more commonly referred to as CC/CV CC mode pumps current into the battery and monitors the battery voltage. When a certain voltage is achieved, usually 90%, the charger will switch to CV (sometimes referred to as the absorption stage) mode and monitor current flowing into the battery. When this current reaches a very low value charging is complete and stops. This process can be ridiculously fast with lead carbon batteries.

Firstly the lead carbon batteries will charge as fast as your solar installation can manage. My somewhat knackered solar panels feed up to 45 Amps into the battery which is 750Ah and the battery is often full before lunch. Speed of charge depends what other machines I have running. I do woodwork. My charge controllers know what state of charge the batteries are at and they modify the CC/CV profile accordingly. When the batteries are full charging ceases. There is no effect on longevity although the first initial charge cycle needs to be a bit gentle and kept below 60 Amps per battery. After that they will take everything you can throw at them. The thing about lead carbon batteries is that they act like a capacitor and so don't have the charge limitations of lead acid batteries. This does not make sense to me. Once the batteries are full they no longer require charging so whatever is available from your solar panels can be used for whatever you want this includes trickle charging if necessary. Why do you think you would need power from the grid? As long as you have a decent bit of sunshine on your panels, resorting to the grid shouldn't come into it. Your batteries are for when the sun don't shine which, surprisingly, happens for almost 12 hours every day.

Yeah. Not just victron but just about every battery company is climbing onto that particular bandwagon. When I got my batteries last year, there were very few choices but now you can find pages of companies advertising them. At 77kg each, mine are heavy but since the intention is to leave them in situ I have no problem with that. The same as older style lead acids, I still target 30% DoD which will give them an estimated 11+ year life. Given the choice I went for the Gel type batteries. They have a design life of 20 years whereas AGM's and other VRLA types only have 15 years. What is meant by design life is standby use not daily cycling. Are they easy to DIY? Absolutely. If you can change a car battery you can do your own Lead carbon installation.

LiFePO4's are not the only storage solution. Have a look at lead carbon batteries. They have similar lifespan to LiFePO4 They are significantly cheaper. They are more robust and don't need any special electronics to keep them safe. The following might help to understand better how they work. https://www.kijo-battery.com/lead-carbon-battery.html#:~:text=Lead-carbon battery is a,advantages of lead-acid batteries. I have 12 x 250Ah gel type lead carbon batteries and I am very pleased with them. I got mine from a Chinese company not the one in the link

Sensors do wear out with time but we are talking centuries rather than weeks. Insects don't really get caught in them but they can, as Onetimewoodwoker has said, trigger the sensor and they can block the sensor if they can get into the electronics. Further reading on how things work is here: https://robocraze.com/blogs/post/pir-sensor-working-principle#:~:text=It utilizes a special type,and triggers the sensor's alarm. Regarding effect of mothballs on electronics. Naphthalene (mothballs) is a hydrocarbon and has no effect on electronic components or wires but as Onetimewoodwoker has said, they are big and unlikely to fit into the sensor casing. I like the idea of ant powder. That's now on my todo list.

Be very careful when handling the plastic detraction cover, that's the white cover over the front of the sensor. It is very brittle and is made more so if in direct sunlight. I have four of these things around my house and they all, except one, stopped working after a short time.

I have had similar issues and, without switching anything off-on, simply cleared my browser history. That works really well. Apparently there can be conflicts created by stored URL's which can slow down and even prevent access to some sites.
