Concept

This circuit can create more complex noises than the original one since it uses all 4 NAND Gates of the chip. Depending on the used values of the parts it can produce metalic spectra or polyrhythmic beats. A optocoupler is used to control one of the NAND gates with a control voltage.

Parts

  • 1* 4093 IC

resistors (R3- R6 are just bridges you can also use wires, for one of them no resistors is used but a connection to the optocoupler is made)

  • R1 470
  • R2 8.2k
  • R3 - R6 10
  • R7 1k

capacitors (use different values for other frequency ranges)

  • C_A 100n
  • C_B 1u
  • C_C 4.7u
  • C_A 47n
  • 4 Potentiometers 500 or 100 kOhm (Alps PCB mounted) unsed for A-D tune
  • 2 Potentiometers 10 kOhm (Alps PCB mounted) used for power and CV amount
  • 1* Transistor (e.g. BC548)
  • 3* switches (MULTICOMP SWITCH, PCB SPDT VERT on-on)
  • 3* Jack connector (lumberg 1502 03 PCB mounted)
  • 1* LED(for optocoupler)
  • 1* LDR(for optocoupler)
  • 1* piece of heat shrink tube(for optocoupler)
  • 1* Battery Clip & Battery

Schematics

All 4 NAND Gates are connected in series from C to B to A to D. The values of the according capasitors are decreasing resulting in a higher frequency from the first to the last gate. The A/B switch connects the A or B NAND gate to the A/B Out-Jack. The B-IN switch connects supply voltage or the C NAND gate to the B NAND gate. The CV-ON switch turns the control voltage on/off. a transistor is used as a LED driver for the optocoupler.

Built Devices

Micronoise pro in a case with additional 4 switches for routing signals of the NAND gates to the control voltage in. There is also a DIP socket for chosing the NAND gate that is controlled by the control voltage.


For this micronoise pro a laser cuted plexi front plate was used. The pads of the NAND gates output were connected to 4 LED with different colors to get a visual feedback of the sound.
