Decade counter with 10 decoded outputs 5-stage Johnson counter. Octal bus transceiver ; tri-state outputs. Dual retriggerable monostable multivibrator with reset. BCD 7-segment decoder, hexadecimal, active hed [8]. The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency.

Combining touchable pads in various manners can bring out interesting — very complex results. Hex inverting buffer replaced by It was further developed for special needs of Theremidi Orchestra. Decade counter with decoded 7-segment display outputs and display enable.

List of 4000-series integrated circuits

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.

List of books about series integrated circuits. DIP 14, SO One of the oscillators is fixed yef the other is coupled with the antenna to its surroundings. To find out more, including how to control cookies, see here: 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.



Octal D-type transparent latch tri-state. Dual retriggerable precision monostable multivibrator with reset.

Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made hev perfect to develope further. Hex non-inverting buffer with tri-state outputs.
