Getting back to the GPS …

Since discovering that the placement of the GPS module in the “homemade” tablet was very critical, I’d moved all the wiring away from the little corner of the box where it was relocated, and then I was in a good position to perform the first on-the-road test of the GPS module, inside the homemade tablet I sometimes call the “Raspi-Riscy” – so as to differentiate it from the Odroid/C1 powered “homemade” tablet I have mentioned in earlier posts …

I sometimes call the second “homemade” tablet the “Raspi-Riscy” – to differentiate it from an earlier homemade tablet based on the Odroid/C1.  The latest homemade tablet project uses the Pi2 SoC/SBC board.  Initially, I installed the RISC OS operating system onto it.
