Yes the price of some of these modules from China, it is not worth turning the soldering iron on to try and make your own. I have ordered a little 12V power supply to complete my project. Total cost of all parts still under £5 This is the 12V power supply I have ordered https://www.ebay.co.uk/itm/AC-DC-converter-power-supply-module-adapter-110V-220V-230V-to-12V-4RKUS/143262160732?hash=item215b17175c:g:ZAUAAOSwEB5c2nVv

No it remembers the code, sorry if I did not make that clear. The point was the receiver has to remain powered when you are expecting the transmitter to activate and turn it on.

Then whatever you are trying to switch / indicate won't work.

^^ That reminds me of our first trip to Oz. We had a meal in a remote restaurant that was little more than a shed, with the dining area on a veranda. The toilet was in a shed at the end of the garden and looked very much like that. SWMBO refused to use it, there had been an advert about that time on UK tv depicting such a facility down under with a .spider hiding under the loo seat. It never ceases to amaze me a woman's ability to "hold on"

This is the transmitter unit I used https://www.ebay.co.uk/itm/433Mhz-Wireless-Transmitter-EV1527-Learning-Code-Encoded-for-Arduino-AVR/292030436727?hash=item43fe5ed577:g:QwkAAOSwB-1YpWii You simply choose a code with the jumpers, then when you apply 5V dc, it transmits. This is the receiver. https://www.ebay.co.uk/itm/1-Channel-Wireless-Relay-433MHz-RF-Remote-Control-Switch-Receiver-SRD-DC12V-10A/192470066162?hash=item2cd01c23f2:g:uJAAAOSwSfNal7~H This runs from a 12V dc supply. The first time you use it, you turn your transmitter on and then press the button on this module, that teaches it your chosen code. Thereafter you leave the receiver powered, and whenever your transmitter is turned on, this receiver module energises it's changeover relay that you can use to switch anything. There are plenty of other variations on this theme available.

I beleive @Stones on Orkney installed a Bio Pure and part of the decision was which one he could get delivered for a sensible price.

Travis perkins. Beat any other price I could find, with the added advantage it got delivered on their own wagon with a hiab to unload it. Some other suppliers said I would have to offload it, and my digger would not have reached high enough to lift it off a wagon. Mine is the ASP6 Here is it being lowered into the hole in the ground

I bought a very cheap 433MHz transmitter and receiver modle from China on ebay, cost less than £3 for the pair.

All seems normal for a 1930's house. I doubt anything actually needs much done unless you are getting visible condensation and mould.

I can't help resolve the issue with that tank. But if looking for an alternative air blower tank, the ones that seem co come up regularly are Vortex, Biopure, Conder and Graff. There are certainly members here happy with each of those (I have the Conder)

That's on a par with when I was a small boy, I asked my dad who's job it was to go round and change the batteries in the cat's eyes along the roads. I don't recall if he tried to explain Retro Reflectors to me or not.

Re smoke alarms. I have gone overboard perhaps. SA in entrance hall, another in the main living room, SA in the utility room (my preference because of tumble dryer fires, I want to know if it is simmering) SA on landing, and another in my workshop the plant room above the garage. And in the Kitchen, AICO do a neat combined heat and CO alarm in one package (shame AICO don't to a matching combinerd smoke and CO alarm) None of this had to be presented as a special fire docment, it was just documented on the drawings where they all went (though I have fitted more than the drawings say)

^^ Inspired by Maglight?

The last 3 houses I have lived in have been locations without street lights. I love it. Nothing wrong with taking a torch when you go out. Everyone in the village pub in winter brought a torch with them and they all put them in a row on the bar. I think most people even went home with the same torch they arrived with.

This forum does like photo's you know. My worst "nail" injury was years ago on a Sunday when I hit my thumb with a hammer. It throbbed all night and by Monday morning it had a nice blood blister under the nail. First thing Monday off to the medical centre at work. The nice nurse used a paper clip heated over a flame to puncture the nail and let the blood out. Short term pain while she did what she had to followed by relief as it instantly stopped throbbing. The benefits of working somewhere with a decent medical facility. Beats queuing at A&E

Remember, the new export payment only pays actual export, metered via smart meter, not deemed 50% of your generation as with the present FIT system. That is why our export payment would be so low, because we self so much of it. It is far better to self use it and save in the order of 14p per KWh than export it and only get 5.5p per KWh I find a 4KW system is about optimum if you are relying on self usage. By dumping excess power to an immersion heater you can use most of what you generate if nothing more useful is consuming it. It is really only in the mid day peak that we can generate more than we can use at times. Larger systems than 4KW and it will become harder to self use all of it, and that I feel is where battery storage will become more important. My first years assessment is battery storage with only 4KWp would not have been particularly useful.

It wouldn't take much up here to create one. The difficulty would be the two nearby towns 3 and 7 miles away that are responsible for an orange glow in the sky to the south east of us. Apart from that it is pretty dark here. I am sure there must be huge swathes of the highlands away from the towns that would (or could easily be made to) qualify for dark skies status. On a clear night it is amazing just how many stars you can clearly see here.

I sourced and installed my own. I got a 4KWp ground mounted system for £1500 with a lot of searching to find everything at the cheapest price. On the basis (reasonable assumption) I can self use £250 worth of electricity in a year, it will have a payback time of about 6 years. Personally I would forget the export payment thing. If I had been able to claim that, I would have been paid less than £10 this year. And in order to claim it, yo must have had the panels installed by an MCS contractor, which would add considerably to the cost.

When I lived in Oxfordshire, we lived in a low lying village on the River Thame. I didn't give much thought to it when we bought it and at no point in the buying (or indeed when we sold it) was there any mention ever made of flood risk. It was soon apparent (first winter) that one of the two roads into the village flooded regularly. Okay that was an inconvenience and sometimes meant a longer journey to go the other way. It also became apparent that sometimes, not as often, the other road flooded. It was always passable but I remember having to drive through flood water every day for weeks one winter. At least 2 cottages in the village flooded regularly, and had been adapted so it was just a matter of put the furniture up on blocks, and mop it all out when the river went down. Several others regularly could not get their cars to their houses and had to don a pair of waders to get home. As it happened our house was on about the highest part of the village, but even then, the flood water one year was almost to our drive, but the house was a metre higher up a bank so still not really at risk.

The builder that built our frame tried to get planning to build a new house in his large garden next to a river. In spite of his garden never having flooded in living memory and the new proposed house being at least a metre higher than the existing one, it was refused.

Well that's a new disk image creates and re booted and all is now working. Shame it took the nuclear option (and over an hour of copying files) to fix it. I am sure just one thing was corrupted, but the mopidy forum proved very unhelpful. Less response than a forum full of builders.

I think my next step is the nuclear option of reformat and load a new image to the memory card and so start a fresh install. I just need a bit of time to do it with a clear head so I don't mess it up. I have backed up all the configuration files to make it easy to restore my settings.

I cleaned mine after a year. I was surprised how clean everything is. The filters just had a light grey coating of what looks just like "household dust" . Since it was all so dry I just hoovered the filters to clean them and put it all back together. Probably the hardest bit to clean was the outside air inlet grill. the fixed stainless steel louvres made it very hard to get a paint bush in to clean the gauze. It struck me when cleaning that inlet grill, how very useful it would be if you could temporarily reverse the fan direction so the inlet grill was blowing out.

+1 I have seen many many 13A FCU's that have got hot, scorched and ultimately cracked by running with a long term high current load. Just dont do it.

Yo will have to cut a channel in the screed. I would (I did) run a 10mm cable to the island. It might only be feeding a socket just now, but it might one day run an induction hob. Run that cable as a new circuit from your consumer unit.
