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.

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.

Can I use any 556 or must it be the LM556?

[tomoliveri]

Any chance you can put the schematic online? geocities has closed..

Hey man,

I'm pretty sure that the 556 only has 14 pins. Correct me if i'm wrong.

Thanks,

The synth HAS to be hooked up to a guitar/piano or whatever right? or can it also just be played off an amp?

[DjFluorescent]

it hooks up strait into amp/mixer or whatever.. :)  i suppose you COULD use the flanger as guitar effects, but  it is really just to shape the sound of the synth

[acidblue]

Where do you attach the 3 grounds ?

[DjFluorescent]

To each other completing the circuit .

I think I see what you're going for, but the instructable would be better if you provided your own pictures and maybe even a sound clip or video to show how it sounds. I'll be following this if you do

[DjFluorescent]

Actually, there are two sound files posted. and i don't have a videocamera. thank you for you input. This is my first instructable :)

[spike shadows (secret agent man)]

I didn't even see the files haha
