3D Print revisited

Joules:
Pete, have a look at this.  You may need to sign up for a free account.

I hope the modifications I have made to the model make it easier to print.  ABS you can just glue it together, PLA it needs welding with a fine point soldering tool.

Hi Joules. I just signed up to grabcad so thank you. For exterior things like this I use ABS as PLA tends to breakdown in time. A question about your setup on the tablet? I was wondering how it can send the info to the tablet. Does it use a USB port or some such. Sorry about all the questions but its how I learn things nowdays and do like technology.  :)

Joules:
Pete, the tablet has a built in magnetic sensor.  The anemometer has four holes in its base, each of these can take a small magnet, in this case two.  The app picks up the changing field as the magnets rotate and it calculates the speed of rotation.

The hole in the centre is for two 8mm ballraces or other low friction bearing.

Weather station radiation shield holding up here, but then it seems like weeks since we had any sunshine.
