DIP 16, SO Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators. The following is a list of CMOS series digital logic integrated circuits. List of books about series integrated circuits.

Digital electronics Electronic design Electronics lists Integrated circuits. Retrieved from ” https: In fact, it is a cast-away of the development in the field of radio — namely: Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.

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. Quad analog switch low “ON” resistance.

One of the oscillators is fixed and the other is coupled with the antenna to its surroundings. Hex non-inverting buffer replaced by With termenvox, this usually undesirable effects were put to good use. DIP 14, SO Hex non-inverting buffer with tri-state outputs. 40049

Octal bus transceiver ; tri-state outputs. This site uses cookies. From Wikipedia, the free encyclopedia.

It produces a ehf audio output. 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.

Dual retriggerable monostable multivibrator with reset. It was further developed for special needs of Theremidi Orchestra. Decade counter with decoded 7-segment display outputs and display enable. Octal D-type flip-flop her positive-edge trigger tri-state. Archived from the original on Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further.


To find out more, including how to control cookies, see here: The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s. Combining touchable pads in various manners can bring out interesting — very complex results.

If you have a thing for DIY electronics, follow the descriptions below. The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency.

Jef human moving their hand acts as a capacitor to ground and adds themself to the oscillating system. The “datasheet” column countains ONLY one datasheet archive. Views Read Edit View history. For more details, please see the next section “Datasheet List by manufacturer”.
