Monday 19th May 2014 – I FORGOT YESTERDAY …

fcpsh football club de foot pionsat st hilaire female footballer as charensat puy de dome league division 4 france… to post this photo of the football, and it was only when talking to Cecile that I remembered.

This is Charensat’s first goal but never mind that for a moment – look at Charensat’s n°12 on the extreme right of the photo.

You’re quite right – it IS a girl. Charensat brought with them a couple of substitutes, one of whom was female. And with there being no official from the Puy-de-Dome league present, no-one saw any good reason why she shouldn’t be allowed onto the field.

That’s one of the good things about playing against Charensat – people are out there to have a good time. Not like the thugs from down the road at Montel-Villosanges who appear regularly (and always in a bad light) in these pages.

Having forgotten to switch on the alarms this morning it was 08:45 when I heaved myself out of the stinking pit. And after breakfast and the compulsory couple of houes on the web pages, I went outside to tackle an urgent job.

Just before I went away, bank two of solar panels in the barn began to lose its charge and finally it gave up the ghost. I hadn’t had time to look at it though.

When I returned, everything working off bank two was thoroughly dead so I resolved to look at it today.

I ran all kinds of exhaustive tests and eventually came to the conclusion that there must be in “incident” in one of the cables that runs between the junction box on the panel mounting bracket and the charge controller.

So after lunch I disconnected all of the wiring and then went to hunt down a new set of cables. Eventually I had a brainwave. I had some 10mm exterior pair cabling in a waterproof sheath. I’d used that to connect up the wind turbine when it was on the other end of the barn, so I went to track it down.

That wasn’t as easy as it should have been either, but I found it and installed it (and that wasn’t as easy as it sounds either) and now it’s all connected up.

And, much to my surpsire, working fine.

So I wonder what has happened there. I can’t think that a mouse has eaten the insulation on the old wiring as it’s sheathed in flexible trunking, but one never knows.

Just as I knocked off (I took 10 minutes to plant my courgettes) Cécile rang up. Perfect timing. We had a chat for an hour and I made tea.

And now I’m off tobed – to see if I can finish this dream from last night where I was in an old wreck of an American convertible that pulled to the left quite savagely when I braked.

Monday 21st November 2011 – WELL, I’M STUMPED!

“Howzat?” I hear you ask.

And I’m going to tell you.

When Terry and I were doing the preparations for the new roof, we put a conduit through the wall and into this conduit we put 3 pairs of 6mm wire. 1 pair was for bank 1 of the solar panels, 1 pair was for bank 2, and the third pair was for the wind turbine.

The two banks of solar panels are wired in and doing what they are supposed to be doing when and where they are supposed to do it, but putting an ohm-meter onto the third pair for the wind turbine, there is no circuit in EITHER of the two wires.

I just don’t understand this at all. I can’t think why this should be. There can’t be a break in BOTH wires, surely?

So anyway I connected up two wires in a kind-of ad-hoc connection and they are working fine and are now connected into the circuit.

And the surprising thing about this (although not surprising if you know anything about me) is that despite the last few days having tons and tons of powerful wind, the wind dramatically dropped the moment I connected up the wires. You could not have timed it better.

wind turbine les guis virlet puy de dome franceWhat I’ve also done is to make up the four guy ropes that will hold the wind turbine mast in position.

I need some special wall anchor mountings for this and I can only get them in the UK at Screwfix. Unfortunately my last order didn’t go through in time and so I can’t get this part done until I go to the UK and come back. I don’t have my contacts to post me stuff these days.

Terry said that he’ll come round some time in the near future and help me push the pole up another metre or so – height is definitely might in these circumstances.

I’ve dismantled part of the scaffolding already and the rest can go as soon as the turbine is in its final position. Once that’s out of the way I can make a start on the roof and I’m eager to get going with that.

“Not a lot of work today” I hear you say. But this does not include the relentless string of telephone calls, and also of visits that I had today.

For once I seem to be popular. I wonder what’s up.

Friday 8th July 2011 – Well I finished the wiring today

And that’s hardly surprising given the time that I had to do it, as when the alarm went off at 08:00 I was already up and about. How about that for a change of habits?

And so by 12:00 I was fed and watered, done a couple of hours on the computer and been in discussion with an American company about some stock and a dealership, I was outside.

The wires that come from the wind turbine and anemometer, and those which go to the solar panels – they are all sheathed now properly (and I seem to have got the hang of doing that now? and go where they are supposed to – down to where the new battery box will be.

And that wasn’t without difficulty either. I managed to finish off the hole in the floor that I started yesterday but as luck would have it, it’s right over the beam. So another hour or so to drill a couple of new ones and saw out between them to give me enough room to feed the conduit through. The charge controller is in place and the wind turbine is wired up to it. Let’s see what that does.

This afternoon I was working on the length of wire to connect the solar panel array to the batteries in the barn – the part of the wiring that is outside. That’s all nicely sheathed now and going where it’s supposed to. And after that, I was fitting the junction box onto the solar panel mounting rails.

That’s as far as I got, seeing as it was by then 19:00 and so a solar shower and that’s me finished for the weekend. Monday will see me finish off the junction box and cut the lengths of pipe that will stand the lower solar panel mounting rail off the wall at the correct 70°C angle. And then maybe I can start to fit the solar panels.

I’m glad that the anemometer is all mounted and that the wiring is properly installed. All I need to do now is to find the data head and I will be in business. But finding anything in my little attic room is an impossible task. Neitzsche said “Out of chaos comes order” but he had clearly never ever set foot in my attic.

Thursday 7th July 2011 – I was right …

… about this wiring not being easy. I still haven’t finished it.

After a morning on the computer and another hour or two proofing this website for Dave, I had another start on the wiring. I’ve put the wiring in place on the mounting for the solar panels – that was the first thing – and then connected those wires up with those for the wind turbine and those for the anemometer and tried to feed them through the roof.

After about half an hour, perched precariously on the top of the ladder, I managed to make some progress, and so it was from there to inside the barn with the ladder to pull it all inside.

Of course, it was miles short and it didn’t look at all right. Yes, it was hooked up on a stone that was stopping it moving. And so back with the ladder outside, pull the cables back and then start again. Was it three or four times I had the ladder in and out of the barn? I dunno, but it’s finally all inside.

An added complication is that the join in the cable for the wind turbine is now right where it can’t be accessed – so I ended up back outside with the ladder, pull the cables back outside, make the join, and then pull it back again.

So now the cable is all in place, I need to cut a hole in the barn floor and I made a start on that. But going downstairs to search for something I noticed that it was 19:30. Where did the time go?

Anyway, I knocked off and I’ll have another go at finishing it tomorrow. And once that’s done, I can turn my attention to mounting the solar panels. Yes, there are all kinds of strange things going on here.

In other news, it’s not for me to comment on the affairs of the News of the Screws. All I can say is that it’s about time that Rebekah Wade got hers, but it seems that Murdoch would rather sacrifice a newspaper and 200 staff rather than a favourite acolyte. If you can guess the reasons why, write your answers on a plain brown envelope and post it to me. There will be a prize for the most interesting response.

But what of course will the usual suspects do on a Sunday morning now that the News of the Screws has gone? Well this is the whole point of this posting. A friend of mine in the newspaper world tells me that all of a sudden the domain names “Sundaysun” and “Sunonsunday” are “no longer available to purchase”. No surprise there, then.

Tuesday 29th December 2009 – Errr … yes …. quite!

12 volt LED light circuit hall les guis virlet puy de dome franceSo I finished the lighting in the stairwell this morning as you can see. There’s a 12-volt LED light now illuminating where the entrance hall is going to be.

. Once that was done I looked at the list of other small jobs to do. One of them was to fit a piece of insulation over the top of the battery box and seeing as that golden thingy was up in the sky I reckoned that this was a good time to do it.

So I removed all of the rubbish from off the top of the wooden lid, cleaned everything out, and while I was about it I checked the batteries – I haven’t done that for a while.

melted battery les guis virlet puy de dome franceThere are 10 batteries in the box – they are all Hawker 92-amphour sealed gel batteries. 9 of them were all nice and cool and simmering away nicely. The tenth was boiling hot and it you look closely you will see where the case has swollen up. This is pretty serious stuff. It’s the first battery in the bank and it’s quite clear from looking at this that the business of handling 250 amps of current per day during the summer has proved to be too much. It’s boiled, the plates have swollen and made a short circuit inside. The short circuit has created resistance to the charge and that resistance is being dissipated into heat and hence the battery is warm and why the charge in the rest of the batteries is down.

Just at that moment a friendly grey cloud blew over the sun and cut off the solar energy so I did a swift disconnection, removed the battery and subsituted another one. And straight away the battery voltage went up 0.4 of a volt.

I’ve rerouted the cables so the positive lead goes into one battery and the negative lead goes into another and that will help to circulate the current a little better but I think that I’m going to have to reconsider my configuration. I can generate a theoretical maximum of about 75 amps but a more practical expectation is about 50 amps. 50 amps seems to be too much for one battery so I’m planning on reverting to the original idea of having two banks of batteries with each of the two banks of solar panels charging up its own bank of batteries. The bus bar, that connects everything together, instead of being between the control panel and the batteries, will have to be sited after the batteries. That will involve more cable, with a greater potential for voltage drop, but unless I can think of another way then that will have to do.

After lunch I made a start on the jungle but I wasn’t there for long. Claude came round for my assistance with his trailer wiring that he coulsn’t get to work. So the rest of the afternoon was spent rewiring his trailer.

And in other news, here is the reason for the latest attempt at airline piracy. One western country wants to remove another civil liberty from its citizens so it needs to create a panic in order to scare them sufficiently so that they will fall for it hook line and sinker. I’m not quite sure what kind of pervert it is that wants to spend all day looking at naked bodies but if this is going to become law I’m going to insist that the people operating the scanners are completely starkers so we can get our own back by looking at them in the buff.

Of course the way to respond, if this ever happens, is to whip up a scandal of our own by accusing all of the airport staff of being pedophiles anxious to have a sneaky look and the naked body of some unsuspecting minor. That should whip up quite a storm, and quite right too.

Sunday 25th October 2009 – It was 9:03 when I woke up this morning

I thought to myself that that can’t be right – and it wasn’t.

Well, it was because in fact the clocks went back this morning and we are now on real time, although by yesterday’s time it would have been 10:03 and that is much more like a respectable time to wake up on a Sunday.

So having breakfasted I had to do a CD of footy photos for Xavier. He has some friends who play for Cebazat and I had photographed them the other week so he had asked me for copies of what I had. And as I was meeting him at Beauregard Vendon where the 3rd XI were playing this afternoon I needed to get my skates on.

First stop though was the fete de la pomme at La Cellette. I’d been invited by Marianne so I went along to say hello. Antoine, Liz and Terry were there so we had a good chat and then it was off to the footy.

fcpsh football club de foot pionsat st hilaire beauregard vendonPionsat’s luck ran out today – they only had 10 players and not one of them was what could be called a goalkeeper. For much of the match Xavier was in goal and today’s pic features him diving to push a Beauregard shot round the post for a corner. There was precious little else to cheer.

On the way back home I went via the brocante at St Gervais. And what a waste of time that was. Most of the stallholders were Dutch and if you are a keen follower of my blog you will know that the problem with the Dutch is that they have no word for gratis. I was looking for a metal bucket or something similar to take away my ashes (well, not mine, the ashes out of the stove) but there was nothing that would do. Some stallholder had a battered aluminium casserole and he wanted €4:00 for it. It’s not very often I come away from a brocante empty-handed. Mind you, I met Gilles and Heidi there and we had had a good chat.

Back home I plucked up the courage to tackle that wiring job seeing as it was now dark. I took me about an hour to do it, most of which time was spent trying to fish the torch out from downbehind the battery box.

We’ll know tomorrow whether it works properly.
