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

The circuit has simplified oscillator sections due to use of Schmitt triggering of gates. The “datasheet” column countains ONLY one datasheet archive. Dual retriggerable precision monostable multivibrator with reset. With termenvox, this usually undesirable effects were put to good use. Quad analog switch low “ON” resistance.

Phase-locked loop with VCO. Hex non-inverting buffer replaced by Preset Divide By N Counter”. 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.


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.

A human moving their hand acts as a capacitor to ground and adds themself to the oscillating system. DIP 24, SO This site uses cookies. List of books about series integrated circuits.

The following is a list of CMOS series digital logic integrated circuits.

List of 4000-series integrated circuits

Digital electronics Electronic design Electronics lists Integrated circuits. Combining touchable pads in various manners can bring out interesting — very complex results.

In fact, it is a cast-away of the development in the field of radio — namely: Hex inverting buffer replaced by The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking. The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s.

Octal D-type flip-flop 0449 positive-edge trigger tri-state. Octal bus transceiver ; tri-state outputs. It produces a two-channel audio output.

Dual retriggerable monostable multivibrator with reset. Hex non-inverting buffer with tri-state outputs.

One of the oscillators is fixed and the other is coupled with the antenna to its surroundings. From Wikipedia, the free encyclopedia.
