Making a simple synth with a 40106 oscillator circuit

So we build a small dual oscillator synth, with a Transistor LFO!
I also go into excruciating detail on how a breadboard works…
EDIT: It’s been brought to my attention that What I call a “Reducer” is actually called a Regulator.

9V Battery Clip
50k and 1M Linear Potentiometer
IRF 540 MOSFET Transistor
3.5mm Audio Connector
7805 5V Voltage Regulator
0.1 uF and 1.0uF capacitor
40106 Hex Schmitt Trigger
Jumper Wires
