also, I cant seem to open the .pde file either, using Windows.
Any advice?

Would it be possible to use four hex inverters instead of four NAND gates?   :smiley-roll:

Yes. Actually the fourth one is redundant, so you could even have two sensors with one hex inverter chip. Of course, the counter/interrupt stuff becomes more complex then...

Hi,
iam trying to improve the theremin circuit. Therefor i would like to change the capacitor inductor setup.
My aim is to generate a higher frequency, hence i hope for a higher precision on shorter distances.

Did somebody made any experinces with different components ?

Is it useful to use components with values far below the given values ? For example 10µH -> 1µH

Is there any other possibility to increase the precision ?

Kind regards
