Nah - not going to work. You cannot be sure the needle has actually caused one layer to blend into another.? Get an old soldering tip and heat-fuse the layers in a number of areas although I'm not

This motivated pinning stacks together; no joy.. The attached script assumes calibration stimulations matching scan ranges for roughly equal samples per frequency decade.

Lithium batteries are designed to be charged at a somewhat constant rate. Chargers are designed to limit that rate to whatever is safe for a battery. The charger in the nanoVNA is probably designed to

I know that many developers protect their work from deliberate claims of prior ownership. But, I suspect that many do not. There are three types of protection: copyright, patent, and trademark. Two of
