<br>The top pond is where one of the frogs lives -- it is also where the tadpoles were placed. However, at least one of them went down the stream (to the top left) and into the bottom pond! <p>Both ponds are lined with permalon (X210-G) which seems
to work just fine, and have a marginal shelf that was constructed out of paving slabs (cheap stuff from Home Depot). The brown (no grass) region round the edge of the pond is due to the liner running out that far underground. It is about four
inches deep, but that affects the amount of water available to the grass -- so it dies! </p>

<br>This pond is around 7ft by 13ft and contains the fish (hence the rather unimaginative name). When the July 2000 photo was taken, it was suffering from foam from the waterfall (which is off to the right). The depth is somewhat under two feet.
There is an overflow at the back left. For the horticulturalists amongst you, the plants around the front edge, between the stones, are various sorts of Thyme. <br clear="ALL">

<p>This is a view into the pond from underwater. This is the Mark 2 pondcam made from a cheap full resolution CMOS NTSC video sensor. It fit in the original housing that I built for the mark 1. [The mark 1 was killed by a lightning storm.] The mark
2 seems to be markedly less sensitive though it could be that it is looking underneath the lily pads, and hence is in the dark! Also I need to get the focus set right -- at least this module has an adjustable focus on it! <!--The pond cam is made
from a (really) cheap video camera from the <a href="http://www.x10.com/products/x10_vk34a.htm">X10.com</a>
people and a bunch of plastic plumbing parts from Home Depot. Total cost
is under $100. Actually I managed to get a special offer on the camera
that brought the price down to about $40 (it didn't include the wireless
receiver mentioned in the kit).

anyone has any ideas how to keep the front clean, then please send me email at the address below. I received an interesting idea that said that if you pass a small current between the glass and another electrode, then the algae will not grow.

<p> This the bane of my existence. Up until the middle of June, the water looked like pea soup. I had tried Daphnia, some patent microbes, etc. Nothing worked. Then I added a filter, and a tablespoon of Muriate of Potash (Potassium Chloride for
chemists). Within a week, the water was clear(ish) and you could see more than two inches. In particular, the fish can now see people, and swim over in the hope of getting fed. </p>
<p>I'm intending to keep adding Potassium during the summer to see what happens. </p>
<p>The water is now as clear as could be hoped for -- now I worry about the residual foam that I get in the mornings. It seems that this is often due to spawning, so I don't worry (much) any more. Certainly you can see the fish chase each other at
high speed, and we do have (at least) one baby...... </p>

THE POND AT CHATEAU GLADSTONE (WITH DEAD PONDCAM) The pond was constructed in the fall of 1999 and actually consists of two ponds connected via a short stream and a waterfall. The total water volume is around 1,000 gallons. The pond is instrumented to the extent of having a camera (see below) and a temperature sensor in it. See the Chicken RFID page to see my latest project. THE WEATHER The full gory details of the local weather can be found on this page. All graphs can be seen here -- this includes a calendar for historical information. I've just started a new page which describes the various sensors that I have. NEWS Wildwater World Championships 22 Jul 2007 We just returned from Charlotte, NC to watch our niece (Olivia Churchill - GBR) compete in the Junior Wildwater World Championships (Kayak). She ended up with 2 bronze medals for individual classes, and one gold for a team class. The Charlotte races were held at the US National Whitewater Center which has a completely manmade course suitable for the short sprint races. Apparently the water is swimming pool clean -- and there are some enormous pumps that pump it round to generate the raging torrent to kayak down. The photo shows Olivia on her second run (the sprint races involve adding the times from two runs together) which led to one of her bronze medals. USAir managed to cancel our (8 am) flight down to Charlotte on Friday morning and couldn't get us there until 8pm -- by which time we had missed the team race. For a full trip report from my sister's point of view (she was travelling with the British team), see her trip report. -------------------------------------------------------------------------------- Hats off to Tilley Endurables 11 Jul 2006 I have worn a Tilley hat (a size 8⅛ T3) for 15 years or so, and it finally wore out after too many visits to the washing machine. I wanted to get a couple of new hats, so I got the catalog, and measured my head, and ordered two (a TH5 and an LTM6). I was somewhat suprised that the sizing guide ended up with me being a 7�. Of course, the hats showed up and were too small -- well, actually they fitted on my head, but were too tight (they are supposed to be held on by gravity and not by pressure on the forehead). I shipped them back, asking for a size 8 (which is what my old T3 had shrunk to). On a whim, I put the tattered remains of the T3 in the box, along with a note requesting replacement. I know that they say that their hats are warranteed for life, but I had no idea if it would actually work. Imagine my suprise, when, a week later, a box arrived with three size 8 hats: T3 (replacement for my 15 year old hat), and the correct sizes of LTM6 and TH5. These guys come highly recommended. -------------------------------------------------------------------------------- Web Crawlers and Content Compression 6 Jul 2006 Since I managed to get content-compression working on my web server (which was way harder than it ought to have been), I have noticed that most of the web crawlers do not make use of it. However, the googlebot and Yahoo Slurp both do enable compression, so it is possible. I have started sending email to all the contact points that I can find when spiders reach my website. One implemented compression within hours, one discovered that they had a bug which prevented it from working, and a couple more are looking into implementing it. The rest have yet to reply. I have now built an automatic Hall of Shame page that lists the current sinners. What you don't see from this page is that many crawlers do support compression. The suprising thing is that some flavors of IE 6.0 don't appear to do compression. -------------------------------------------------------------------------------- For all the news, please see the diary. TOP POND AKA FROGGY POND June 2001 May 2001 April 2001 February 2001 Snow (oct) 2000 October 2000 July 2000 The top pond is where one of the frogs lives -- it is also where the tadpoles were placed.
