Cool to see a magnetometer group started. I built a magnetometer using a compass, the ones that have no form of liquid inside to dampen the needle movement. I...
Welcome to all who have joined by now !!! I already see some familar names :-) Well, I would suggest we wait a few hours until most members of the other groups...
Hannes, others, Glad to see this group started. I had planned to start researching and building a magnetometer this winter as a project. I know of a couple of ...
I was hoping something like this would come along. I have a currently functioning magnetometer which uses a compass whose needle is held East-West by an ...
... Hi Charles! Welcome to the group too :-) Since you mentioned Joseph's mag. I had a look at his page again (visited his site a few months ago, but...
Finally THE group about Magnetometers has been launched. I am very interested in Diagrams, circuits and idea's on Magnetometers. Thanks in advance, Jan Wansink...
... Hi John! Welcome to the group too :-) You're describing what I'm concerned about too. I want to try to run a magnetometer in my flat, but I suppose I will ...
... Mayer. The FLC100 looks interesting. Considering that Fatquarters has a USA branch and a price of about $80 US, i will likely go that way. I have a...
... Thank you too for the hint about Fatquarters. I just found their page: http://fatquarterssoftware.bizland.com/store/page1.html (the sensor page) The FGM -...
Dear Fellow Magnetometer Enthusiasts, Just a quick note to thank Charles for forwarding me the information on this group and Hannes for starting it up. I look...

... Hi Joseph! Great to see you aboard aswell! Welcome! :-) I had a quick look at your magnetometer pages yesterday and it looks really complicated. Must have...
Hi all! Well, for those who don't know me, here is a short introduction, what I am doing and what I plan. Feel free to post your own introduction :-) I'm 27...
Hi Hannes & all, My compass is situated on the roof outside my bedroom window, no disturbances from computer,tv or vehicles. I do however get a slight...
... Greetings Hannes, Don't be put off by the apparent complexity of my magnetometer - it isn't but my web site is. ;) I have gone into great detail on the web...

My name is Frank Carson, and I'm a member of the VLF group as well. I am interested in that and building a magnetometer (though I've never built one). Thanks...
Aloha Folks, I recognize many of the names I see in this group and some of you may know me, but I thought I should more formally introduce myself and let you...
Hi Mark! ... That sounds promising! Meanwhile my "soda bottle mag" is finished. Let's see if it works in my flat. ... I just started to think about of how to...
Dear Jim, Welcome. I am familiar with your SkyPipe work which has contributed greatly to the amateur radio astronomy community. If your ears were ringing...

Welcome to all new members who have joined today :-) Hi Jim! ... Did fatquarters produce the FG sensors ? If so, I suppose the FGM series is the next...
... Hi Joseph! The KMZ series has already a Wheatstone Bridge inside. Philips states, that a constant current source is good for eliminating temperature drift....
Dear Mark, ... Nice to learn about someone else using Linux for data acquisition. :) I have successfully interfaced an Analog Devices AD976, a bipolar, 16 bit...

Dear Hannes, ... Well, that's handy. The output of a Wheatstone Bridge is dependent on the magnitude of the excitation although I'm more familiar with constant...

Hi Joseph! ... It was me speaking of Linux ;-) Actually I just experimented with the parallel port under linux. I don't use a special driver - I just access it...
... Good night Hannes, ;) The 74LS74 is a dual JK flip-flop with external set and reset. It was included in my design because of the external, hardware timing...

Hi, everyone. I, too, started out to build a proton precession magnetometer some years ago-even had some <really> pure h2o to get on with. Forget why it never...
