Gauss 2 ... return of the gauss!
As promised here is part two of my home made gauss meter magnetometer project ... the dreaded circuit diagram. All pretty simple really: the 9v DC is smoothed by the 0.33uF capacetor before being reduced to 5v by the power supply module. Then the 0.1uF cap adds further smoothing before the voltage reaches the hall effect sensor. The output from the whole lot is then measured by the multimeter ... any cheap digital one will do.
In the next part I will talk you through assembly and interpreting the results ... happy days!
