Not my 'thing', but a subtle and significant improvement in readability whilst maintaining your desire to show change at the lower levels. I think if I were to do 'logs', I would probably do it in reverse so most change would be shown at higher levels - BUT the scale max. ranges would probably be re...

beteljuice no like !

It give a visually dispropionate view of change at low levels - surely you would be more concerned about eg. wind speed change from 10 => 30 than 0.5 => 2.0 ?

As possible (and small) negative values are meaningless, and the index is quoted as integer % it would be better to modify the code slightly <?php $ftemp = '73.0'; // why are these numbers in quotes ? $rh = '87'; // Convert F temp to C temp $ctemp = (5/9)*($ftemp-32); $ct = round($ctemp,0); // why a...

Unless you are doing cloudbase by some kind of observational measurement, I don't see the point !

As has been stated elsewhere, the calculation is for the lowest (cumulus) type formation, which may or may not occur.

ie. the sky could be clear or have higher level cloud formation.

Have you ever thought of reading the help files or the wiki ? Make sure that in cumulus Internet Settings - Sites/Options : Web Settings that the Realtime box is ticked. As your html pages and graphs are being uploaded the web path you have must be correct, and you say you can manually upkoad the re...

Another hiccough is that the Sager technique also (correctly) employs 'trend' eg. change (or not) of wind direction over perhaps last fours hours. These are intuitive to an observer, but without external logging / coding this data is not 'native' output to C1. The Zambretti forecast could be more ve...

... and times

It's all very loose - It depends where on the globe you are, and if you want to 'measure' them by temperature or astronomically

There are a few sites (can't remember offhand) with 'calculators', but if I remember correctly it's more a case of hours of 'useful' windspeed, typically > 9 mph for an effecient turbine. It's surprising just how few good sites there are ! - I suppose a good rule of thumb would be if you live near s...

BTW - using the balun(s) should be good for 300m with unshielded twisted pair

The problem (presumeably) is not the video data but the power ? - what about a splitter or a powered repeater after the network adaptor at the cam end ?

beteljuice

Not happy about you positioning your sensor in a 'tunnel' between the shed and the trees - both can be heat sources !

The code is 'old' ;) [edit: some of my points covered even as I was typing] Whilst hating CSS, it does have its uses :o A more upto date philosophy would be to have your timer displaying in a named <div> or <span> with it's content being updated. In a similar vein, pure eye-candy, is to have TWO <di...

The only problem is if YAWCAM or your PC or your 'line' goes kaput ! A simple PHP solution is: <?php // Time to wait before showing the offline image in seconds $offtime=300; // 300 = 5min // path/name of off-line image $offline = "NOCAM02.jpg"; // path/name of latest webcam image $cam = &...

Thinking aloud ..... If you have php and the graphics library on your server you should be able, for example: If top left pixel rgb values > 'dark' values image = cached last good (or perhaps avi of the day ?) else copy latest image to cached last good put 'too dark' text on image use latest image (...
