has anybody had any experience building one of these kits?I have the circuit board built and I am starting to mount it in a plastic box....I am trying to...
Mike, I'd use a 12 V. AA pack. The 5V regulators drop out at 7.5 volts which is a lot closer to 9 than to 12. By the time a 12V pack is down to 7.5 volts...
Thanks very much Erich,I really like the kit and hope to get the PVC this weekend....has there been any problems with the audio out ic going bad from plugging ...
Hi Michael, No problem with the audio IC. Did it go out on you? Your check bounced...insufficient funds. So, the bank charged me $20. Please send another check...
Sorry for the mix up.....my wife tells me the Bank messed up......I am very embarassed.....I will be leaving the group now and I am very sorry......mike ... ...
Hi Michael, You shouldn't leave the group because of this, it's a bank screw-up. However, I owe everyone an apology for having posted this to the magnetometer...
John: Have you any expereince on the long terms stability of the KMZ51 and the stability over wide temp ranges ? Regards ... come to mind. The variance of the...
I have done more work with the HMC series as I used to work for Honeywell in the oil exploration portion of the company. The KMZ51 is licensed under one of the...
HI all, I'm still using the HMC1022 ic, i had majopr problems with temperature drift. After alot of messing about & experimenting i found that the HMC1022...
John, I think we met once before when you were at QSI. I am doing a general review of AMR sensors. I have done many FG designs before. I want to understand and...
... If you use metal film or 1% or better precision resistors, you greatly reduce this problem. Carbon resistors have a terrible tempco, and it's negative. ......
Hello group: I'm still fairly new to this group and have just been lurking. Can someone tell me what this K-100 kit is and where there is some info on it? I...
Paul McClure wasn't it. I did not recognize your handle. Fluxgates have a lower noise floor by at least an order of magnitude. These are resistive devices and...
I built the EPE fluxgate gradiometer. I'm having problems with my top sensor. It either reads "zero", or it reads exactly the same as the bottom sensor. I...
To All, I replaced the capacitors on the sensor array and now the mag works great. If anyone else has this same problem, it is probably a bad capacitor or bad...
We lost the software for this logger last month when bag contain the disk was forget on the field. the Logger was not useful until the software is load to the...
Hi, I am searching a way to measure precisely strong fields like 0.5 T. Does anyone know how to make this? A proton meter in MHZ range? Or does that not work...
... Pieter, Nuclear Magnetic Resonance (NMR), which is the basis of the so-called proton precession magnetometer is alive and well in the MHz range. ;) There...

Hi ! Am looking for toroidal fluxgate circuits to build....I have currently one going but I need to get the sensitivity up....any info on mounting the toroid...
You might try over at the ulfelf group. There is a fellow over there by the name of Tom Lambert you should ask for concerning toroid fluxgates. He is the...
The light blue line is the low level light signal which should give you an idea as to when things are happening. Times are UTC and location is central Texas,...
Hello I am a physics teacher interested in making a magnetometer to replace the conventional deflection magnetometer(compass type). The range of magnetic...
Has anyone found any type of coaxial connector for the Speake & Co. FGM3 sensor? I am interested in any type of connector, coaxial or not. Currently I have it...
Hi Bill, We distribute the FGM-3 in North America for Speake & Co. My response to your question is, why? Why a co-ax connector? For long runs I use 2...
Hi I use the power conector that you use to the floppy drive, fits perfectly. regards Lars ... From: Erich Kern To: magnetometer@yahoogroups.com Cc: Bill...
