Kermit - wow. Couette flow = difficult homework in a graduate course in heat transfer. 2% heat transfer and 98% turbulent flow fluid dynamics, where the math was a bit challenging. Was able to turn that into paychecks, so a toast to you and yours! Back to the topic: the field of robotics (i.e. navigating remotely operated vehicles) also plays with "fluxgate" technology. Some hobbyists make their own with LM555 timers and wire turns on ferrite torroids, and post their circuits on the internet. Honeywell makes sensors and sensor assemblies, mostly for the aviation community. They post their data sheets, down to the discrete component level, on their website. I thought (and still do) that this level of investigation was beyond the intent of this list. And so I'll fade into the background again.
