Reverselandfill Noise Build Document

Noise Oscillator Build Document. V6 Standalone 9v
The Noise! Synthesizer is a CMOS IC based instrument.
The synth has 4 squarewave oscillators that modulate each other and go throught a clock divider.
After that, the separate divider outputs are mixed and shaped together.
Start with the Resistors:
The one 10R resistor has the color code: 'brown-black-black-gold-brown'.
It is used at the power input as a fuse.
Bend the legs of the resistor 90 degrees and place the 10R resistor at the R1 location on the PCB.
Solder the resistor and cut off the legs with a sidecutter.
The three 1K resistors have the color code: 'brown-black-red'.
These parts act as output protectors.
Place the resistors at R2, R3 and R4
Solder and cut the legs.
R5 to R8 can be skipped, they are for CV input (eurorack)
Starve is a modification option.
Look at the end of this document for more info!
Connect the middle and right hole of Starve together to bypass this option.
Use a snipped-off leg of a resistor. Bend the leg in a U shape and solder.
If you skip this step, the module will receive no power!!

IC sockets:

Take the tube or foam with the two IC sockets and the IC's. There is one with 16 pins and one with 14 pins!
These IC-sockets are to make the placement (and possible removal) of the IC's easier.
Take out the two IC-sockets. Attention! These sockets have a direction. See the semi-circle gap?
On the PCB you can see this marking as well. Place the 16-pin IC socket in IC2.
Flip over the PCB and solder two legs, on in the upper row, one in the lower row, diagonally from each other.
Flip the PCB back to the other side to check if the IC-socket is flat to the PCB.
