Since we don't really want to resurrect an 8-year-old thread, here's a new one 🙂 Do you have access to your meter? If so, it will have a reference number which you can take to your local MEA/PEA office and they should be able to tell you what you owe. Your 9,000 BTU A/C will use about 900W when working hard, normally one assumes that a correctly sized unit will run at about 30%, so 300Wh (0.3kWh) per hour of use. Of course, total energy consumption is very much dependent upon the weather, you may find your unit struggles to maintain 21C during the warmer months.

Sounds like a 1990s modem (remember those?). It's going to go pear-shaped when the bots actually develop their own encryption which we can't decode.

Few people know that before he was famous, the late Johnny Cash tried a chip full of salsa served backstage in Possumneck, Mississippi that changed his life. It was spicy and tangy and smoky and so good that he just couldn't get it off of his mind. Unfortunately, there was no jar, no label. Now, there have been rumors that Johnny had kind of an addictive personality. He would sometimes disappear for days on end. People attributed it to drugs or alcohol. The truth is that he would roam the country searching for the special hot sauce of his dreams. He heard rumors and whispers of the deadly condiment and followed them to countless dead ends. He stopped at every Tex Mex restaurant, truck stop, and Mexican grocery in the South without finding what he sought. One day he heard tell of an old woman, a witch down in the Mayan peninsula in Mexico whom it was said, made the best salsa in the world! He cancelled his next five gigs and headed south. He rode donkeys, Jeeps and horse drawn wagons. He traversed deserts, mountains and jungles before finally reaching the fabled village where the old bruja lived. He found and entered the old woman's hut. As luck would have it, she was one of his first big fans, having caught one of his shows at that Holiday Inn in Possumneck, Mississippi while attending a Salsa Aficionado convention where one of her jars of salsa mysteriously disappeared and somehow made its way to a bowl backstage. She consented to sharing her secret recipe with him only after he agreed to write a song for her. She shared the special Tomatillos grown in Mayan soil. She gave him the seeds from a rare Mexican pepper and showed him the special pan with a rounded bottom, similar to those used in the Far East that she would use to simmer "la lima" or "lime," the source of the salsa's tanginess. He asked her if he could just use his regular flat-bottomed pan but she insisted that he must use the round-bottomed pan. From this came the inspiration for the lyrics: "Because you're Mayan, I'll wok the lime!"

A heat gun or gas torch on the inside of the pipe will soften things enough to work the pipe out. I wouldn't trust the re-used fittings on much pressure but when needs must ... One of many YouTube videos: -

I believe it is.

At school, nah. Bloody log tables! (included sin, cos, tan etc. etc.) At college etc. we actually had calculators (although we were supposed to also have slide-rules, nobody ever used them).

Nearly, SOHCAHTOA, which everyone remembers, is a special instance that applies when one of the angles is 90o (right-angle triangle), the sine and cosine rules allow you to calculate missing sides and angles for any triangle. Shamelessly copied from https://thirdspacelearning.com/gcse-maths/geometry-and-measure/sine-rule/ In this case I knew two sides (the height of the girder thingy [measured at 0.45m] and the length of the brace [chosen as 3m to be half a 6m length of steel]) I also measured the angle between the girder and the roof joist at 95o using my trusty combination-set. I needed the other two angles to cut the brace to fit, since I was on a roll I worked out the missing side too. 1. Law of Cosines We can use the Law of Cosines to find the missing side (let's call it 'a'): a² = b² + c² - 2bc * cos(A) Where: a = missing side b = 3m c = 0.45m A = 95 degrees Plugging in the values: a² = 3² + 0.45² - 2 * 3 * 0.45 * cos(95°) a ≈ 3.07 metres 2. Law of Sines Now we can use the Law of Sines to find the missing angles: sin(A) / a = sin(B) / b = sin(C) / c Let's find angle B first: sin(95°) / 3.07 = sin(B) / 3 sin(B) ≈ 0.97 B ≈ 76.6 degrees Finally, we can find angle C since the angles in a triangle add up to 180 degrees: C = 180° - 95° - 76.6° C ≈ 8.4 degrees Therefore: The missing side is approximately 3.07 metres long. The missing angles are approximately 76.6 degrees and 8.4 degrees. Of course, I didn't actually remember all this bollocks, those cogs have long since rusted up. Mr Google provided the WD-40 EDIT In a bizarre coincidence, when I phoned my parents yesterday Mum told me they had "found" my school reports and that now was the time to embarrass me by reading them. Scary! They also had my acceptance letter to the MOD(N) Technician Apprentice Training Scheme which is what got me to turn a hobby into a profession (I actually had visions of being a vet).

Madam has decreed that it will get cheap tiles to match the existing. They are small money so I will not risk my life by arguing They are so cheap that if a large mango falls onto the chicken house (which has the same tiles) it will sometimes punch through!!

Moving right along. I was more than mildly surprised that my Grammar School trig. actually worked to calculate the cutting angles (nothing is at 90o, it's a scalene triangle so you can't just use Pythagoras, you need to remember the "rule of sines" etc.) resulting in minimal gaps when welding. For those worried about it blowing away in a breeze, each of the 6 "legs" has a 50x50x50cm cube of concrete (about 300kg each) buried in the ground. The area is also pretty well shaded from horizontal winds by the house and the garden wall. Now, what was that about my (ok, my step-son's) welding?? ** ** The bolts used to hold it all in alignment before welding are not being removed, I'm not that daft!

I've tried that in the past with my original micro-inverters. The net result was that the MPPTs wouldn't start at all 😞 I never investigated why, just used a mains power supply, current fans run off a 12V regulator from the battery packs.
