Atari Punk Console

Nowadays, almost everything is digitalized. Most of the synthesizers nowadays use programming. Luckily, there are still a few reminisces of non-digitized synthesizers. Of more of the complex ones are ones like the Luna Mod or the Crazy Looper that Brian McNamara created. Some of the overly complex ones might be the WSG by Music From Outer Space. Next in line would be the simpler 40106 oscillators. Of the simplest are some 555 tone generators like the VCO. A bit more complicated, the Atari Punk Console or if you prefer, the "Stepped tone Generator."

The nice thing about this one is that it is compact enough to fit in your pocket so you can carry it around with you opposed to the huge, bulky ones.
 

Step 1: Stepped Tone One: Look For Your Bear (Bare) Necessities.*

You will need to find:
2 555 Timers or 1 556 (I chose two 555s since it was cheaper, I had about a hundred and I memorized the pinouts.)
4 Terminal Blocks (or headers.)
0.01 µF capacitor
0.1 µF capacitor
1 Kohm resistor
Power source with connector to the board (I used a nine volt battery clip.)
Jumper Wires
Printed circuit board, protoboard or, breadboard
Speaker (I found that the 8ohm speaker works well with a high current supply...I used a rechargeable 9 volt battery. Therefore, You may want to add a amplifier.)
2 50Kohm potentiometers (After intense and critical testing, I found these work the best.)
Enclosure
