Re: Arduino Magnetometer Testing

Frequency counting is the way to go. When I started my magnetometer project some years back I was looking for a suitable low cost counter, but I couldn't find anything on the market cheap enough with the resolution needed for sub nT measurements. The Arduino ( or Rasperry Pi) micro systems now avail...

Re: A Blank Saturday Sun - 17th february

A very quiet sun there, Mark.

Decorating here as well this weekend, trying to get it out of the way before spring.

Re: Arduino Magnetometer Testing

Nice one, Carl.

Are you also able to capture/export the data as a CSV file (frequency and time)?

Re: Magnetometer article

Thanks guys.

Rainer, there is a digital download version. You'll see the links if you go to the magazine web site.

Re: Arduino Magnetometer Testing

Hi Rainer,

My concern is the local reinforcing steel which might impact performance. Better to be located away from steelwork and electrical cables if you can do so.

BTW there is a tutorial on this in the library section of this forum.

Magnetometer article

Dear solar friends,

For anyone interested, there's an article in March's 'Sky at Night' magazine on my magnetometer.

Cheers.

Nice FDs, Matt. It has been so long since I last imaged the Sun, I think I've forgotten how ;).

Re: Arduino Magnetometer Testing

Cool. Looking forward to seeing more from this little (and cheap) device. Temperature fluctuations are the main issue I've found with my magnetometer. I've had to go to significant lengths to protect the integrity of the signal data using close temperature control at both the sensor and the receiver...

Re: Ha Full Disk 11th February

Nice FD under challenging conditions, Mark.

We're having work done on our house and my gear is 'inaccessible' at the moment. Frustrating to see the Sun out for a short while, but being totally unable to image.
