so,
i have a jogwheel (65mm diameter) attached to this: https://www.aliexpress.com/item/330...earchweb0_0,searchweb201602_,searchweb201603_
(a angle hall sensor, that gives me absolute position)
i would now like to embed a few (2 or 3) buttons into the jogwheel so that depending on where i put my finger on the wheel i can switch functions of it.
since the wheel is on a rotating sensor i have no means to attach cables to it. embedding a micro controller and battery and going wireless seems also out of the question, since the wheel is only about 8mm high.
i stumbled across this: https://www.amazon.com/Android-Customizable-Battery-free-Shortcut-Smartphones/dp/B072Z7MY9G
could something along these lines be made attached to a teensy? i was always under the impression nfc could only output static data, no button changes.
has anybody any experience in this field or another suggestion to get data wirelessly and without power (or in a very small package with power) or even a wired solution with some kind of circular rail or similar
