Super job. :) Looks very durable and should last a very long time. Have you thought about fitting a solar powered fan for when the sun directly hits the shield?

How about this running from a 40w lamp
Surprised how little light it needs to get going
don't forget to reverse the fan blade so that it draws air thru the unit
Kit available here £5.99

Finished the solar fan mod working very well for such a small and cheep fan
I put the solar panel in a lunch box cut a hole for the panel and sealed it with silicon sealant with a piece of clear acrylic on the outside

That's absolutely brilliant. Thank you. I will need to make a mod as well for it to accommodate the solar sensor, but I am sure I can work from your design and make up the last bit as I go along. Thank you so much.

Nick

Hi Pcomer
Not really, rather time consuming,
but I do enjoy making things like this and half the fun is making it for yourself
Think next time i would use 4 6mm threaded rods to make the mounting easier and more stable

Brilliant ideas - well done.
My stations not far from yours - I must compare air temps and then plan my shield!

That's a thing of beauty. I have a WH 3081 which has a solar panel to power the transmitter etc. This is attached to the top of the unit with the temp sensor inside, here is the dilemma, the solar panel needs to be in the sun but the temp sensor needs to be in the shade. I'm not confident the enclosure is very effective, temps seem a little high. Anybody have this model done anything about this? greg

Would it be possible to fit an extension lead between the solar panel and the sensor unit

Great work and a nice and neat design.

I am working on something similar using your design and have a couple of questions.
What is the purpose of painting the inside of the dishes, I assume to absorb heat away from the sensor?
How effective was the screen without the fan and with the fan.
Is the fan at the bottom blowing up or at the top drawing up. The fan is not shown on the original plan.
