Profile of wind gusts
Don't know if profile is the right word but I've been thinking about anemometers and response to gusts. I would like to know the peak wind force in gusts as that would seem to be important in damage from the wind. From feeling wind force I think the peaks can be quite narrow - but how narrow? How of...

Re: Arduino and 1-wire based home built weather station.
I've been giving some thought to the sensor system for the anemometer. Currently the idea is a magnet on the rotor and reed switch underneath in the fixed part. This gives two closures per revolution as the reed switch closes with either N-S or S-N magnetic field. With one revolution per second esti...

Re: wind direction is too sensitive
Wind vanes generally "flap about" a lot and what's needed is damping. I'm using magnetic damping in my DIY weather station. A rare earth "supermagnet" is attached to the back end of the vane and rotates within about a millimetre of an aluminium saucepan lid. This damps the wobble...

Re: Arduino and 1-wire based home built weather station.
I've 3D printed a number of parts for the weather station mostly for the wind instruments. Here is a new anemometer. A rather poor photo on the table and perched on my anglepoise type light/magnifier. I can post photos of the individual parts if anyone is interested. Anemometer_22.jpg Anemometer_23....

Re: Arduino and 1-wire based home built weather station.
Hi Steve and everyone - I'm back (at last) :) Much has happened since I last posted here and I have a number of updates to post. Bottom line is that I shall be resurrecting this project shortly and have already been planning a local wall display in my living room. Steve, hope you are well and still ...

Re: increase accuracy of fine offset rain tipper
I guess one way of coping with both heavy and light rainfall would be to use two rain gauges. This is a possibility I had thought of for my weather station. No problem if you're making your own weather station but not an option for comercial stations. The incidence or extremely heavy rain seems to b...

Re: 1-wire info and recommendations
Hi folks :) I'm back and still working on various electronics projects including this one though it's been "on the back burner" for quite some time now. I'm hoping to resurrect it very soon and have been looking at a wall mounted display in my living room. A lot has happened since I last p...

Re: Arduino and 1-wire based home built weather station.
Thank you Steve and Mark :) Steve - My working 3D printer is the UP! Plus 2 which is a small commercial unit with proprietry software and hardware. It's very good though more expensive than the more common RepRap based printers and kits. I was lucky to buy a secondhand one at under half the new pric...

Re: Arduino and 1-wire based home built weather station.
As one wire devices go, http://datasheets.maximintegrated.com/en/ds/DS2413.pdf is pretty simple. You can take the existing library for another one wire device and just code up the two commands you need, based on example. It looks like all you need is reset, select, write a byte (F5 or 5A), read a b...

Re: Fed up with Fine Offset. I want to start from scratch?
The F.O. resistors are 1% tolerance and my measurements show them as actually being much closer than that. But my measuring equipment is only accurate to 0.1% so can't say closer than that.

Re: Fed up with Fine Offset. I want to start from scratch?
I'm building an Arduino plus 1-wire based station. Arduino handles 1-wire with a library - I have another thread on it - though been too busy to progress it much lately.

Re: Fine Offset WH1080 - Spider Proof Rain Gauge
Haven't had any spiders in it since the mod Get leaves in the funnel though and a certain amount of grit all of which needs cleaning out now and again.
