Dag Off

Reminds me of a small touring caravan. You stand up and hit your head on a shelf.

Even though solar thermal (ST) will work well all year round, you may find that photovoltaic (PV) is the better option, even for your domestic hot water (DHW). It needs no servicing, no moving parts (apart from an inverter fan), gives you 'power flexibility' i.e. you can use it for other things, and can be incorporated into a rook structure, so looks better and helps keep the roof temperatures down (as long as you are using the power). I have no idea how stable the electrical grid is where you are, but it may help, with the right setup, to give you some energy independence. Keeping a few lights and a fridge, or water pump, going can be useful.

Efficiency changes with airflow, the slower the better. I really should get around to making my Mk3 model, was thinking of using silicone paper for the plates as it is cheap, thin and fairly rot proof.

It is the bit at an end of a project to put the errors right and show extra data.

In all fairness to the RPi, none of that was a surprise, the spec is well known. I admit there are things I would like on it, RTC and a few ADC/DAC pins, but it is what it is. In 2013 we could never have imagined the RPI at 30 quid.

So a week to go until the end of the year. Anyone willing to post up what worked and what didn't on their building projects. Preface it with 'Worked' or 'Not Worked' and then a brief description. You can follow it with a long rant if you like.

Welcome. I lived on a tropical island once, I liked it very much. Last time I was local to it, I managed to not use the air conditioning. Was my contribution to offsetting the flight.

Get them a very small engined car, one that can do 70MPH, just. Then load it up and send them on a trip. The physics is almost the same.

Down here, a lot of shops are using the O2 wireless hotspot for free customer internet. I have no idea ho much it costs the shops, but it is a pretty reliable service and covers a lot of Penzance. Now I know this is a town, but the concept is the same for a rural area, just stick some repeaters in cars (you can get a RPi Zero W and an extra USB WiFi adapter for 15 quid). How hard can it be.

I think the IET (the electrical people) use 2.5K.m.W-1 for soil. They tend to be conservative, so stick with that. I think there is a table in the 17th about it. And just remember that every time your plants get watered you get some extra losses. And from an experiment I did several years ago (grass growing), the plants add nothing to the thermal properties.

If the ISP/OR fail to connect a property at 10 MBs, will they get fined? If the fine is cheaper than the connection costs, they will just pay it. I still fail to see why we are using fixed lines, surely we can create a wireless mesh network that only has the hardware set up and very small electrical running costs. Why aren't the open source community working on this.

Would mean a trip to Redruth, and that is scary https://www.theguardian.com/society/2014/jan/04/hidden-cornwall-beaches-poverty-domestic-violence. Still, not Camborne, which made the national press this week https://www.thesun.co.uk/news/4914205/christmas-tree-worst-cornwall-cornetto-residents/

Just been to Poundland and they are currently not doing the variable voltage adapter. They may be doing it in the new year. I also had a look in B&M and Poundstretchers, neither of them have them either. So may be a supply problem.

In a way I do as it was not directed at anyone or any cultural group of people, and as @Hecateh points out, this is an adult forum, bit like Radio 4. It can also be used to show what is acceptable and what is not. So by sticking it up for prosperity, we have a bench mark. Yours, the Shining Wit.

Or do we want the video

Over at the other place I used the term WTF Someone had to ask what it meant I feel a case of the Malcolm Tuckers coming on https://en.wikipedia.org/wiki/Malcolm_Tucker

I am willing to put up any picture or bad language, I get posts deleted on a regular basis. I blame it on my mute tourettes syndrome https://www.johns-jokes.com/mute-tourettes-syndrome

@Russell griffiths You and your pictures

There used to be a really hopeless food van in Aylesbury called 'Tuckwits'. It was doomed to failure.

I am still reading it

I think I have mentioned before that for every rule we have that says you must do something, there is at least one other that says you can't do it. Maybe some good will come out of it as it will clear up some confusion. I am an optimist by nature.

The needles will fall off if it is too hot
