Welcome to THE forum - looks like a great project.

I tend to agree that it might well be just a classical control theory problem if it were not for the fact that this deep learning stuff is disrupting classical theories across the piece. Although a vast training set it required in supervised networks for improved accuracy one might envisage a situation where an unsupervised network might learn from a number of houses which while being very different do have similar reactions to similar stimuli. Good to chew it over though.

Are not all icings carbs - well C6H12O6 like anyway, feel like a right onoff I do.

Welcome to THE forum for self builder. Seems like a very tight budget but might be doable. Perhaps the optimum route would be to find a derelict existing dwelling with a good foundation so you can build on that and get the VAT back, there are some rules on how much you can retain, although you will pay more for the plot all the services will be there and planning should be straight forward. The trick is going to be to draw a polygon around Dunstable with the periphery lying on a 1 hour travel (fast car / slow car / bike / train etc). That's quite a long way up the M1 (don't go south as prices get silly) but not as far across country. Then look for the cheapest areas and try and find a derelict building - auctions are good.

The assumptions here need unpacking a bit perhaps. When talking about BSP we usually assume parallel threads because the technical extra P (BSPP) is assumed while NPT does what it says on the tin (National Pipe Taper) has a tapered thread. To get a correct 'mating' you would need to use another NPT fitting. Tapered threads are designed, among other things, to seal themselves as they tighten with minimal packing while parallel threads usually need some additional sealing such an olive, a sealing face or washer. If you try and get an NPT (male) to mate with a normal BSP thread (female) it only meets at one place so is very challenging to seal and can split the female fitting. There is a NPS (straight) form as well but you don't see that about much. All the details can be found here: https://www.valvesonline.com.au/references/threads/ from Oz but as it is talking about the standards of two other countries I think it can be relied upon.

The more I read through this thread the more I wonder if a deep learning classifier might be able to work this all out - eventually. We still seem to be applying classical scientific theory to it while other methods might work a little better in the massed data era. Have a look here for a broader view of these ideas. My musings are that in a well insulated house all the time series thermal events will have data characteristics that might be classified, mostly just slopes of temperature but when tied in to other events around the systems such as power consumption in / gas flow to the kitchen (With rates of consumption here it would be possible to get ahead of the cooling / heating systems) perhaps, the burglar alarm being disarmed = people coming in, it should be possible to classify the events and then propose control schemes that can cope - although naturally deep learning can do little but work with the laws of physics. Anyway just some musings.

Control theory 101 great explanation. Need to mull it over I do.

Welcome to THE forum.

Yes as @PeterW suggests just do another wall plate along the end wall, it will fit in the gap and get right into the corner, simple.

Sorry Ian but still wondering how the roof (if it is a roof) is supported at its edge. The wall plate usually has the joists mounted on it but the surface that is placed on the joists still need a small amount of support at their outer edge alongside the wall.

This is what we have done - so it is scaremongering. The BCO has no problem with me building it neither does the structural warranty company.

Welcome Ian - there are a few of us in the Kent chapter of BH.

Sorry, but how is the edge of the floor secured to the blank wall on the right, should there not be some edge support running along it, is that what the gap is for?

I started this thread as serious look at a new piece of research which might or might not have value for us in the long term, now it has turned into a pig's ear! So rather than have everybody posting mushroom / fungi names here I have found a reference to all, well many, of them: https://www.mssf.org/cookbook/names.html so now we can all play games seeing if we can get a mushroom name into our posts, not just on this thread but everywhere - mischievous or what!

We used Advanced foundation Technologies system for our passive slab which I was very pleased with but there are loads of passive slab companies out there.

Welcome to THE forum for self builds. Not all of us are kit builders, we are very much like you - stick building but with engineered timbers I-joists. This gives us 300mm thick insulation between the I Joists and then another 40mm on the outside to give us great U values.

I thought the house in Henley was stunning - ICONIC (overused word I know) and they took their time to get it right and must have spent millions. I guess its about learning how to appreciate things which don't exude bling but nonetheless have cost a lot to achieve, as was I suspect the case with the Henley house last evening.

So it becomes clear just how seriously we take real science round here - Luddites the lot of you....all the fungus right out of it.

yep - looks like that, you start thinking this idea has a future and cancel your PV order.

Looks like mushroom power is just around the corner - no really it is, see here: https://www.bbc.co.uk/news/science-environment-46127318

About 2 weeks ago our immersion heaters stat overheat protection tripped out. I changed the stat and yesterday it, the new one, tripped again. So something funny is going on. I guess it must be the boiler circuit overheating the tank and I adjusted the boiler stat down 5 deg last time but that seems not to have cured it. Is there another failure mode I asked myself. The only thing I can think of is that the bypass valve is leaking so even when it is shut hot water continues to get through onto the coil. I will check that later but is there anything I have missed?

If they can see it then I think you have a right to see it as well, just put in a FOI request and get them to send it to you or the link to the document online.

Sorry, just catching up with things after a very hectic rush about weekend and aftermath. I guess that is why using the 'blink' has merit as it should be exactly what your meter reads and you can get the actual current consumption from the blink interval, should you wish to go in real time mode rather than only waking up every 30 seconds as @TerryE system does.

There must, in the modern world, be a low power equivalent of the Must there not. How about the maxim DS1371 which has 800nA current demand and looks like it is RAM focused rather than Eeprom. Eds idea could work as well but it may rum up agains start up latency at high power demand as pulses cone thick and fast.
