hello all,
i'm a music tech student building a terpsitone variant. i need to implement a device with one channel of loading mode EF sensing, but with large field size (in the range of 2 - 6 meters), that can be varied with a potentiomemter.
because i will be using the output of the device as a control signal rather than a sound source by itself, i do not need an implementation that has good tone quality. that's why my plan right now is to use Arthur Harrison's Minimum Theremin (http://home.att.net/~theremin1/100/minimum.html).
but what in the schematic do i change to boost the size of the electric field? (i know the size of the antenna is a factor, and i will be using a large one). but is there anything else in that schematic that can be adjusted to maximize the field size and still be able to change it with a variable resistor?
making giant fields seems like it would be fun and useful but surprisingly i can't find much info about it.
thanks for all your help!!
