Build a Hall Effect Gaussmeter

at 5:32 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Rick Hoadley (the Magnet Man) has put together a simple gaussmeter project that uses a hall effect sensor to measure magnetic fields. The video shows two meters, one that uses a PIC microcontroller to measure and show the values and the simple version. There is no plans for the PIC version that I could see. Perhaps if there is enough demand Rick will make some plans and code available.

“Have you ever wanted to find out how strong a magnet really was, or how the strength of the magnetic field varied as you changed the distance from the magnet or the temperature of the magnet, or how well a shield placed in front of the magnet worked? Voltmeters are fairly inexpensive and easy to find, but where do you purchase a Gaussmeter (also known as a magnetometer). I built a hand-held Gaussmeter for measuring the polarity and strength of a magnetic field. It uses a linear Hall effect device and some op-amps and resistors and things from Radio Shack.

I will first describe a very simple, inexpensive Hall effect device Gaussmeter you can build for as little as $6. Then I will describe a Gaussmeter with a few more bells and whistles.”

    I have an SWR meter for my radio stuff, and it has a built in field strength meter. I am not sure if it is measuring some form of gauss, but it might be worth investigating to see if it is the same. I would hate to lug that big box around for the simple purpose of measuring field strength. Does any one else know if they are the same?

    I dont think they’re the same.. seems like it would be a hastle :/

    Where’s your hacker spirit! The word “hassle” shouldn’t be in your vocabulary :-)

    Looking into it a little more, it appears that they are (somewhat) of the same school of thought. Field Strength meters measure electromagnetic waves, so why couldn’t you use Hall’s Effect as a solution for this?

    nice and cheap!

    Haha, yeah yeah, you’ve got me on that one bro

    The hacking sprit is what makes life worth living. Kinda like getting a Fon router and installing dd-wrt on it. Its just pure happiness.

    Hexypoo, I think thats the tightwad’s spirit :P
    The hacker spirit is upgrading its ram ;)

    Cool beans. Maybe that will have to go on my list of things to whip up :)

    Hexypoo: I had the warranty voided on mine 5 minutes after I walked through the front door at home :-) You cannot even tell it’s a linksys router anymore. I have it in a different enclosure with a 12 DBi patch antenna attached :-D
