A human moving their hand acts as a capacitor to ground and adds themself to the oscillating system.

Two pairs are used as variable frequency oscillators, lower and high frequencies, and third pair is used in mixed amplifying, filtering, oscillating feedback mode to play around with the existing pads all over the system.


Hex non-inverting buffer replaced by Octal D-type transparent latch tri-state.


DIP 16, SO BCD 7-segment decoder, hexadecimal, active high [8]. Hex non-inverting buffer with tri-state outputs.

Octal D-type flip-flop ; positive-edge trigger tri-state. Quad analog switch low “ON” resistance. Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators.

List of books about series integrated circuits. Decade counter with decoded 7-segment display outputs and display enable. This page was last edited on 2 Decemberat Digital electronics Electronic design Electronics lists Integrated circuits. One of the oscillators is fixed and the other is 44049 with the antenna to its surroundings.

With termenvox, this usually undesirable effects were put to good use. Preset Divide By N Counter”. Decade counter with 10 decoded outputs 5-stage Johnson counter.

In fact, it is a cast-away of the development in the field of radio — namely: The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking. The free-running frequency no hand near the antenna of this variable oscillator should ideally be the same as that of the fixed frequency oscillator — making the difference of these two frequencies equal to zero.


Phase-locked loop with VCO.


The “datasheet” column countains ONLY one datasheet hev. DIP 14, SO Combining touchable pads in various manners can bring out interesting — very complex results. The following is a list of CMOS series digital logic integrated circuits. The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency. Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.

The circuit has simplified bef sections due to use of Schmitt triggering of gates. The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s.
