Sub-Oscillator

Here is a step by step instruction by Mateo Carabajal, very detailed, so that we can all take home a sub-oscillator.

Ingredients:

1 x PCB Suboscilator
1 x 100K Potentiometer
1 x 330K Resistor
1 x 0,01µF Capacitor (code 103)
1 x 10µF Capacitor (16v)
11 x switches
1 x 9v Battery connector
1 x Female mini-jack connector
1 x CD4060 IC + Base
10 x Leds

Tools:
1 x Thin solder (30 or 40W) if ceramic tip better.
1 x Clamp pliers
Thin cable

Instructions:
Make the PCB sub-oscillator from “Los Aparatos”. Here is the file if you want to do one in Eagle:
PCB Suboscillator. The eagle is a shareware that allows free PCB’s with all features turned on (to a certain size).
 Download it from here.

This is the image of the PCB if you want to print it directly:

2. mount the base and weld

3. Now the resistance, no matter which side we place, we put it where it says R1 or 330k.

4. The capacitor:
Have no polarity, place it where it says C1 0.01 uF. If a ceramic capacitor has a code that says 103.

5. Potentiometer: weld it like you see in the picture:

6. Now the 10 switches:

We put two cables that says SW1.

In order always follow the same provision in the cable connection to the switch (simple inverter).
The middle piece of the switch and the outer needle, will be connected to either end parts of the switch. In this way we know when output is activated and when deactivated.

7. We soldered the 9V battery connector, the black wire goes to GND and the red states is placed where it says +9 V.

8. We soldered the jack 3.5 as follows:

Place the integrated cd4060.
We are now ready to prove our sub-oscillator.

Connect with a cord plug 3.5 to an audio amplifier and check that the battery in place a sound pace. Turn the knob to check that the frequency up or down, The litmus test is to turn off all switches and should not play anything …

If all goes well we move forward, if not right, we review the welds to the switches.

9. Now the LEDs.

Its longest side is positive and the negative shorter.
Positive leg will connect the end part of each switch and the negative leg of the jack which is land mass or GND, as follows:

We continue with the rest, all the negative short legs of the LEDs will be connected together and go to GND …

10. Now we can start thinking about where to mount our sub oscillator … the bigger our firm better. The disposition is at the discretion of each.

Here are a few pictures of the installation:

Sub-oscillator finished and ready!

to oscillate that the world ends!!
