The modular Flunk synth is an Atari punk console with added flange capabilities. It produces a pulse wave using a LM556 Timer.
The flange can be used to process other signals such as guitar via the flange input.
It is powered by two 9v batteries. One powers the console, and the other powers the flange.

(This is my first instructable)

The first audio sample is me playing it through a simple sequencer. The second is pure Flunk.

Step 1: What You Need.

Components:
Resistors-
1K (2x)
10k
4.7K
Capacitors-
10nF
100nF
10uF (electronic)
IC-
LM556
Potentiometers -
500K lin (2x)
100K log
Other-
SPST Switch
1/4" Jack
LED (i used a flashing multicolored LED)
9v Battery clip
PCB

You will also need a flange pedal. I used a FAB flange pedal, they are only $15.

Step 2: Tools

Wire
Soldering iron
Solder
Screwdriver
Pliers
Electrical tape
Wire strippers (optional)
drill

Step 3: The Voice

I won't get too deep into this step, but it is the most crucial. Follow the schematics carefully. This will take the most time and patience. I don't have any breadboard, but if it is available for you, test all your connections before you solder it up.

Step 4: Add Flange

Take apart the flange pedal using screwdriver and set aside plastic stomp box (it can be recycled).
Now desolder the led from the board and remove the LED. now add wire were the LED once was on the board.This is so it can be fixed to the enclosure we will be putting it in. I replaced this led with a RGB color changing one(shown below). Then used the Blue-violet one as the Osc On/Off indicator. . now do the same process with the on/off switch, but replace the switch with on of your choosing (i used a spst)

Step 5: Enclusure

Please have fun with this step! The only limitation is your imagination. Find fun and interesting containers or boxes to put your projects in. This is were you get to show your creativity and add a personal touch.
One thing to keep in mind, you will have to drill holes in this to add your knobs, switches, and LEDs. so try to find easy material to do so. (mine is made of plastic)

Here is how I drilled the holes for my enclosure. I wanted it to look professional. also keep in mind playability when deciding on where to drill holes.
