We had a supply (replacement) Chemmy teacher like that, boring as flip! He looked like Alf Garnet and so that was always his name "Alf", still don't remember his real name. Incredibly I still passed Chemistry O-Level. Of course, he had zero control over a class of rowdy teens, so high jinks were order of the day. A Bunsen-burner on the water tap projects a stream a long way! Connecting the gas tap to the water tap (using the rubber pipe off the bunsen) fills the gas pipe with water (there was a lot of trouble over that one, apparently it damaged the gas supply).

On by light - off by dark AC exhaust fan switch
Crossy replied to lopburi3's topic in The Electrical Forum
Alternatively, assuming you can get the dark switch apart, many of them have a change-over relay anyway, you should just be able to move the output wire to the normally closed contact. -
Long ago in a galaxy far, far away. OK pretty close really ????

Yeah, oxidation needs oxygen and moisture (didn't you do the iron nail in water experiment in high school?), but differential metals will corrode with just a little damp.

It's already ruddy Baltic even here in BKK, "Global Warming" my backside We have friends in Buffalo who are really struggling ????

Mass exodus from Bangkok for New Year celebrations begins
Crossy replied to snoop1130's topic in Bangkok News
Good tyres and serviceable brakes optional then. -
The issue is the battery terminals themselves; the differing metals (aluminium terminals vs copper busbars) can cause corrosion. Vaseline will definitely help by keeping the damp out but for a "proper job" use the real stuff. It's loaded with Al dust to fill any minor gaps (even the scratches from the emery) with conductive goop. For a few 10s of Amps, no major issue but when you get into "real" power every milli-ohm matters ????
-
If you are making up your own battery packs I would also invest in some Uni-Seal jointing compound. A quick rub over with emery on the terminals followed by a smear (you really don't need much) of this stuff will ensure a good and long-lasting contact. Use it on all your high-current joints. It's definitely not cheap, but one tube will last you a lifetime, shake well before use. https://www.lazada.co.th/products/i2156648662-s7185722295.html

I would add that wrenches/spanners, socket sets, screwdrivers, hammers, files, power drills (and drill bits of various formats) etc. etc. would come in my bracket of "normal DIY tools" rather than being specific to solar. But if you don't have them, now is a good time to go shopping ????
-
Yeah, good idea. In order to manage any job you really need both a 1/2" square drive and 1/4" square drive set (a decent 3/8" square drive set may do the trick). Have a look in your local DIY places, quality varies vastly and you really don't want the cheapest of the cheap.

Metric, although there are imperial fasteners on sale in some places the closest metric size spanner usually fits OK. Get a set of combination spanners Or
-
Yes, but you have to verify it does do DC current, many don't and do AC only.
-
But your place is most definitely a "special case", how many of us have overhead cranes?

You mean rolling blackouts like Texas? https://www.texastribune.org/2022/11/29/texas-power-grid-winter-ercot-forecast/ Madam doesn't do "one at a time", she's an all or nothing woman.

The kettle (1,800W), 4 slice toaster (1,800W) and 1,500W microwave (heating the beans for the toast) totals 23A ish, a 20A breaker would probably stay on, just long enough. Two circuits in the kitchen is a good idea ????

10A is good on lighting with 1.0 or 1.5mm2 cable (I find 1mm2 is a bit small for mechanical strength). Stick the outlets on a 20A if using 2.5mm2 cable although only kitchen circuits are likely to get anywhere near 20A (4.4kW total) anyway. Fixed appliances as appropriate for their power consumption.

Pool equipment and ladder erthing/grounding
Crossy replied to unheard's topic in The Electrical Forum
Anything powered by the 220V supply. Fans, electric barbie, Ghetto Blaster, that sort of thing. Really, really avoid having power outlets in the pool area, they are way too tempting. -

Please let them be 12V! Mains pool lights really are accidents waiting to happen! -
From another forum. My flight was being served by an obviously gay flight attendant, who seemed to put everyone in a good mood as he served us food and drinks. As the plane prepared to descend, he came swishing down the aisle and told us that "Captain Marvey has asked me to announce that he'll be landing the big scary plane shortly, so lovely people, if you could just put your trays up, that would be super." On his trip back up the aisle, he noticed a well-dressed rather Arabic-looking woman hadn't moved a muscle. "Perhaps you didn't hear me over those big brute engines but I asked you to raise your trazy-poo, so the main man can pitty-pat us on the ground." She calmly turned her head and said, "In my country, I am called a Princess and I take orders from no one." To which, without missing a beat the flight attendant replied, "Well, sweet-cheeks, in my country I'm called a Queen, so I outrank you. Tray-up, B***h."
