992	Hi all, i'm currently doing a 3-axis magnetometer using 2 HMC1022 chips. However, i'm unsure if my schematic design is appropriate. Can somebody shed some...	resham_84	Dec 18, 2008 10:31 am
993	Hi, Are you using this to detect changes in the Earth's magnetic field or just for a digital compass ? Mark From: magnetometer@yahoogroups.com...	MarkD marky26_uk	Dec 18, 2008 11:49 am
994	Hi, Yes I am using it to detect the variation in Earth's magnetic field Best regards Emmanuel O. Abe +234(0)803-447-4604 Physics department, Federal...	abe emmanuel abeemman	Dec 18, 2008 2:57 pm
995	Hi, Well the circuit you have posted has nowhere near enough gain to detect the disturbances in the Earth's magnetic field, the gain feedback resistor on your...	Mark marky26_uk	Dec 18, 2008 3:04 pm
