Introduction: Modular "Flunk" Synth
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.
500K lin (2x)
LED (i used a flashing multicolored LED)
9v Battery clip
You will also need a flange pedal. I used a FAB flange pedal, they are only $15.
Step 2: Tools
Wire strippers (optional)
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.
Step 6: Put It All Together
Now just attach all the controls to where you drilled your holes. Make sure to use electrical tape to keep your connections from touching each other.
