  1. Didn't Apple already get caught out slowing down older iPhone models to "encourage" users to update??
  2. Actually, when I first move to Seoul and reading zero Korean I did like the lemon scented shampoo our local store had. I later learned that the label said "Sunlight"
  3. I would lay odds that there's a back-door (or 10), I'd say a dead cert! Some years ago I worked for a UK company that made some prototype equipment for a German client. There was a relatively "secret" manufacturer menu accessed by a 6 digit code. The first version access code was 191418 - The client discovered this and for some reason wasn't very happy Version 2 used 193945 - Prompting a rather "cool" response. V3.0 used 421966 - By this time the client had either given up or failed to understand. Yes, we did get that manufacturing contract but the production equipment used a different code.
  4. Which of course comes with its own set of "problems"
  5. Yeah, the earliest our meter chap ever comes is the 16th (always February), the latest the 19th. So we are set to not export on those days every month. If he comes before the 19th I can manually let the brake off. We are lucky that he usually rolls up about 7AM before any significant generation has started, but ...
  6. BTS to start tours of historical nightspots around Nana and Asoke stations
  7. Now if they could just program the EVs to spontaneously combust in the Kremlin basement parking ...
  8. The electric car chargers along one of the most important freeways in Russia are all down Monday after the Ukrainian company tasked with building the main components in the chargers used backdoor access to hack them, shut them down, and program anti-Putin/pro-Ukrainian messages to scroll past on their screens https://jalopnik.com/russian-company-outsourced-the-main-components-in-ev-ch-1848603252
  9. Numbers for February, a short and variable month with a low daily production of 15.7kWh and a high of a very satisfactory 43.9kWh. Total solar for the month is 759kWh whilst we used 228kWh from PEA.
  10. Or at least accurate as-built drawings (which are about a common as unicorn droppings). Not, I hasten to add, one of my jobs, but someone cut a very expensive core!
  11. Many grid-tie inverters available which have no-export built in, far easier than messing about with separate units. I'm 100% certain there are units available to monitor your grid connection and turn on dump load (water heater) when it looks like you might export. I've not actually looked for one mind.
  12. It does from a volt-drop perspective, it doesn't affect safety but excessive drop will reduce the power available to heat your water.
  13. You'll be fine, I can shave far, far more rapidly than my teen grand-daughter takes in the shower.
  14. Yeah, could be, it's a loooong time since I registered.
  15. If you can do a decent inline twist and solder it (you need a big iron [>100W] to get a good joint) then add heatshrink that should be good to go. 6kW on 2.5mm2 is definitely marginal (do you have teenage girls?), probably OK on a shower for "normal" usage.
  16. Have you got the latest version of the app? I thought the later ones had an English option.
  17. True, if it's likely to get damp then choc-n-heatshrink would work ok.
  18. If you have space the black TB-25 screw connectors are better than choc-blok. They are 25A but are fine for your shower, there are 45A ones available but unlikely in the retail stores. If you must use choc-blok strip the wires long enough that both wires pass under both screws for a better connection. Do check where your heater is fed from, it's not at all unusual for the "installer" to splice into the incoming supply bypassing all your Safe-T-Cut etc. protection ????
  19. Yeah, there's a set near us in northern BKK that go red-flash about 21.30. Turning right there would shave 10 minutes off my journey. I don't, the way that the approaching traffic treats flashing-red as "green" scares the willies out of me. 10 minutes on my journey is nothing compared to ...
  20. I video call every week to my youngest (Line) and parents (Skype) in the UK, both using video, both on my ancient i5 PC. Occasional issues with delay / echo / some other problem, but it's usually fixed with a re-dial. One thing I could never get working reliably on my PC is Facebook Messenger, it always moans about not having access to the mic / camera / both, neither of the other apps (or Zoom or Teams or Google Meet) seem to have this issue.
  21. A Tesla charges with the Yallorn brown coal power station in the background. Yallorn is one of the most polluting power stations in Australia. Cited for closure in 2028.
  22. So, I've been asked on a number of occasions to clarify the various types of solar inverters and what they can do. Here's my Idiot's Guide. Off Grid So the classical solar installation would be a simple Off-Grid system. The panels charge the batteries and the batteries run the house. The grid is not involved anywhere although some users might install a generator type transfer switch so they can switch to grid or a generator if the batteries are dead. This system has the issue that the maximum load can never be greater then the inverter maximum output. On Grid or Grid-tie By far the most common system here in Thailand, it also happens to be the cheapest as there are no batteries involved. The inverter supplies power to the network whilst the sun shines, it is synchronised to the grid and so offsets the consumption from the grid. A plus of doing this is if you need more power than the solar is supplying it simply draws that extra energy from the grid in a totally seamless manner. On the negative side is that, because there are no batteries, if the mains goes off so does your local power even if the sun is beaming down. If you generate more power than your local loads are using then the excess is exported to the grid. The old disc-type meters happily run backwards during export saving up the energy for you to use later. This "net-metering" is technically illegal and if the meter reader sees the meter going backwards you will likely get a "no reverse" meter installed. If you already have an electronic meter these don't go backwards, indeed they might actually bill you for any power you export! In order to mitigate any export issues many on-grid inverters have a zero-export function so the inverter exactly matches what the load is using. Of course any extra power available from your panels is simply wasted. Off-Grid Hybrid In order to offset the disadvantages of an off-grid system the off-grid hybrid adds a mains powered battery charger into the mix. This allows the mains to top up the batteries or "help" the solar if the sun is feeling tired. Most have a "bypass" which allows the load to operate directly off the grid if necessary. These hybrids usually have several modes available depending upon how you want it to behave. The usual setting would be "Solar First" whereby the load draws power from the solar most of the time, if there's not enough solar then the extra comes from the batteries and if there's still not enough (batteries discharged) then the remainder comes from the mains. Of course, so long as you have solar and/or juice in the batteries you never actually end up in the dark even if the grid is off. Like the simple off-grid system this unit still has the issue that the maximum load can never be greater then the inverter maximum output. On-Grid Hybrid The on-grid hybrid is really the ultimate system combining all the advantages of off-grid (never in the dark) with the advantages of on-grid (no limit on power available if the grid is on). Again there are many modes to choose from the usual one would be "Self Usage". The inverter attempts to keep your grid current at zero where it can. If there's excess solar it charges the batteries, if there's not enough solar energy is pulled from the batteries to keep your grid consumption at zero. Most also have an "Essential Power" output which gives UPS like functionality when the mains is off to keep your important stuff (lights, TV, PC etc.) running when the grid is down. Like the on-grid systems these inverters can export to the grid if the batteries are full and you are making more than you are using. The same caveats regarding net-metering apply of course.
  23. IMPORTANT UPDATE 25/04/22 - All of the guides etc. are now at https://www.localfoodheroes.com/ the links are later in the thread but since we are seeing interest again I've edited the OP. As a Brit I like my bacon sliced a bit thicker than is commonly available here at a sensible price. I'd also rather have "back bacon" not the "streaky" which seems the norm. So I had a go at curing my own. Instructions here http://www.localfoodheroes.co.uk/?e=541 do follow the quantities accurately. Prague Powder #1 from Lazada - https://www.lazada.co.th/products/i168877082-s209361163.html Ziploc bags, Lazada again (I got the biggest I could find) - https://www.lazada.co.th/products/i2330372790-s7881063502.html I left out the optional sodium ascorbate 'coz I couldn't find it. Pig loin from makro, looked for a piece with a bit of fat. I did just a 1kg piece just in case it went wrong, this was a mistake, should have done more After 6 of the longest days in my life we have a result. Looks, smells and tastes just like the real thing. Deemed totally acceptable by Madam, we've nearly scoffed the lot already. Hand slicing, even with Madam's razor sharp cleaver wasn't perfect. Slicing machine on order.
