FWIW, just saw on the science channel that our sun's magnetic field extends out to the Ort Cloud- way past Pluto. :o

That price of $1,200 seems a tad high for that chip.
Should be: https://www.amazon.com/TMR2102P-Linear-Magnetic-Sensor-package/dp/B00OY9K2F6/ref=lp_12725042011_1_1?srs=12725042011&ie=UTF8&qid=1517498611&sr=8-1

Of course, lenp's idea is feasible too. :)

Hoping all us kids got what they were hoping for this Christmas! (if you've been nice all year!)
The only plan I found that works for not enough storage space is to buy more space. Time to move! :)
