-==== First investigate, then invent! Here are a couple of links we are looking into... ====
+Of course we want to invent our own musical instrument, with our favorite single-board and some non-contact sensors. Basically we could use anything that can be used for measuring, even a thermometer, but to get started let's give some ideas according to the common boards and the electronics that are cheap and easy to handle. Again, and this is the interesting part of making a musical machine, please let your ideas go wild and try to realize them....
-But more of interest is that we can look into ALL of the popular single board computers (micro:bit, arduino, RPI, ESP32, etc...), and find designs and code online on how to make a theremin. Also we can chose our own sensors to control body movements for amplitude and pitch, continuous or discreet, code and ... PLAY! Inventing a new dress for an old synth.
