Title: December DSC
Post by: mickw on Nov 04, 2010, 17:22:18
I have asked for 3rd to 5th December - watch this space

With the issues of mud, and power only in certain areas which require you to travel into the field, wouldn't it be better to maybe consider Blacklands on occasions like this, which has hardstand all around and the facilities (free) are within easy reach.
Only a suggestion ;)

I agree but - I think Blacklands is also "closed" but without the "open" option - November to February I think

*Correction*
This is old news !

http://www.blacklandsfarm.co.uk/news_41142.html (http://www.blacklandsfarm.co.uk/news_41142.html)

There doesn't seem to be anything about closures this year - Thoughts anyone ?

Plus they've got the bird in the shower  :o

I was in the usual spot - I put my tent in the area nearby the fire extinguisher.  But I parked too close to the trees ands overnight the car sank into a "spongy bit".

Personally, I don't mind going back there but Mick will never make it, so Blacklands might be the better choice for Winter camps.
Title: Re: December DSC

If I remember Blacklands was only closed for 1 month of the year.

We do have the option of putting the cars on the gravely bit near the toilets out of season with tents just inside the field. That way cars, even Micks caravan, won't get bogged down.

Lights from nearby caravans may be an issue but I doubt it.
Title: Re: December DSC

All the caravans will be empty in january

Post by: mickw on Nov 08, 2010, 09:25:28
If we were to set up near the gravel car park there will be a better view of the South and West skies, North and East will be restricted by the trees (similar to the restrictions in our preferred position S and W).

If the house to the South turn their floodlights on - there will be a white out.  I have only seen them turned on once.

Hi,

Well I feel vindicated a bit, I said this campsite turns into a bog, I went there twice with the Subaru and on the second time October the car nearly got stuck after little rain, no idear what its going to be like next week.

Also the river isn't going to help with mist etc.

Having said that the chip shop and the railway cafe is great, so maybe summer camps can be done at Rother Valley because they do not let it get too busy.  Also it is dark.

There are still a few sites I have never got too which are open all year some with hard standing.  I'll have a look at them again.

Chris

I'll make my final decision at the last minute - I've got lots of things to do at home after putting our house on the market, so I'll likely only come down if it's clear and probably only for one night.

[Off Topic]
Yes, that's the plan.
On the High Speed Line (the "Javelin" trains) one can get from Ashford Int'l to Canary Wharf in the same time as Sidcup to Canary Wharf (once the DLR extension opens early next year).

Kids have now grown up, so with nothing to tie us to Sidcup it's extremely tempting to move out into the country.

Thats what i thought at quagmire common that time,
in the end Chris had to pull me back to the path,

it was only a foot or two but enough.

The clay was so soft even with the 4x4 it just clogged the tyres.

Friday is the only night forecast to be clear but before and after is forecast to be wind, rain and/or snow (and cold).

Don't see the point of loading everything up for one possible night, assuming I can get the van out of the kerb (grit lorries don't come down my road)

Weather report, its -4 we had 14" snow last ngiht and its forecast for more, my mount in the garden has snow more than halfway up it and the seat and chair are nearly burried.  I think this is a DSC for Mark only, I expect him to cycle down dragging the C11 on a sledge.

Most sensible people here are looking out the windows.

Apparently its going to be clear tonight for a few hours, hmm shall I?

It's this one from Maplin:

http://www.maplin.co.uk/Module.aspx?ModuleNo=223254

Though it was half price at the time I bought it about a year ago.

If anyone else has a Maplin's weather station with PC software, don't use the provided software as it is #$£* - instead use Cumulus, much better:-

Also works with Oregon and just about any other USB connectable weather receivers.

Don't know about you, Mick, but I rejected to USB model on grounds of price only to discover a few weeks later that the USB station now costs what I paid for for the version that can't be connected to a computer.  :roll: I'm reluctant to upgrade as the one I have has developed a fault after only about six weeks use.

Take it back and change it if it's faulty.

Tell them you don't even mind upgrading (Not your fault if the price is now the same  ;))

I'm currently searching for the receipt as they probably won't accept if I don't have one. When it thaws out I'll try powering it down and checking the connections but I have the feeling that the wind is somehow getting into it. On two occasions now it's recorded 159mm of rain in less than 12 hours!

The rain guage is a little rocker. Not a great design, but it can be affected by wind blowing into it. I think every time it rocks, it empties itself of water and counts a set quantity of rainfall, so if it is rocking due to wind it will give false readings.
Title: Re: December DSC

The rocker design is standard. If you saw Gardeners World last week you would have seen a met office guy using one.
Title: Re: December DSC
Post by: Mike on Dec 03, 2010, 17:44:26
yeah but what I mean is, it is made of leightwight plastic and inside a box that has quite large air gaps. Some kind of wind baffle and heavier material would have been more ideal.
Title: Re: December DSC
Post by: PhilB on Dec 03, 2010, 17:51:24
Thanks for the info, guys. I thought it would be something simple, but had an impeller driven by water flow and connected to an encoder disc in mind. There's no guidance in the instructions but it is mounted rather close to a roof surface where turbulence might be a problem. I'll have to follow your lead, mounting it rather higher up and experiment with improving the seal between the top and bottom of the box.

I thought you where very ignorant in not saying hello when you arrived, but you must have not seen me.
