It produces a two-channel audio output. Archived from the original on Combining touchable pads in various manners can bring out interesting — very complex results.

Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators. Octal bus transceiver ; tri-state outputs.

Retrieved from ” https: List of books about series integrated circuits. In fact, it is a cast-away of the development in the field of radio — namely: Octal D-type transparent latch tri-state. For more details, please see the next section “Datasheet List by manufacturer”. Preset Divide By N Counter”.

Quad analog switch low “ON” resistance. Decade counter with 10 decoded outputs 5-stage Johnson counter. Octal D-type flip-flop ; positive-edge trigger tri-state. One of the oscillators is fixed and the other is coupled with the antenna to its surroundings. The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking.


Phase-locked loop with VCO. Hex non-inverting buffer replaced by Hex non-inverting buffer with tri-state outputs. By continuing to use this website, you agree to their use. From Wikipedia, the free encyclopedia.

The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency.

BCD 7-segment decoder, hexadecimal, active high [8]. DIP 24, SO To find out more, including how to control cookies, see here: Dual retriggerable monostable multivibrator with reset. The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s. Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further.

DIP 14, SO Digital electronics Electronic design Electronics lists Integrated circuits.

Semiconductor: HEF4049BP (HEF 4049BP) – HEX INVERTER BUFFER…

With termenvox, this usually undesirable effects were put to good use. A human moving their hand acts as a capacitor to ground and adds themself to the oscillating system.


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.

The following is a list of CMOS series digital logic integrated circuits. This page was last edited on 2 Decemberat It was further developed for special needs of Theremidi Orchestra.

If you have a thing for DIY electronics, follow the descriptions below. 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 inverting buffer replaced by Views Read Edit View history. Decade counter with decoded 7-segment display outputs and display enable. The “datasheet” column countains ONLY one datasheet archive. DIP 16, SO The circuit has simplified oscillator sections due to use of Schmitt triggering of gates.
