Lunchbox Synth

Crammed a digital delay, spring reverb and function generator into a lunchbox. The fact that it says korg is sort of a synth geek joke. _ Big thanks go out to tonepad.com and generalguitargadgets.com for being such great resources for this beginner. All boards etched by me using press-n-peel blue and RadioShack etchant.

audio samples are here for all settings full and here for a little restraint

    I remembered your synth when I was at Goodwill looking for an enclosure for a project and bought a lunchbox for it. Thanks for the cool idea.

    ive an old casio key board i just gutted ive plans to put it in somesorts box , with were the keys press down on swiches {is a 2 parter} on the surface along with its other pad switches , im still searching for a good containr . im wondering if any of the digital delay, spring reverb and function generator would work hooked to it as well for added sounds , it has midi in/out but my kore2 synth is already in use with upgraded devices . have you seen any keyboard hacks that look easy ?

    I love this. I was thinking about building a lunch box synth but with the control panel inside instead of using the metal lid. Then it would be its own case as well.

    That's a great idea! Also it'd be a little easier to assemble. ;) I'm finding that the solid core wire i ended up using for convenience is starting to break since everyone wants to see inside and they flex when I open the door. :( I recommend using a clear plexi/acrylic for your panel so everyone can see the guts without taking the box apart. Also post a pic or a link when you get yours done. I'd LOVE to see it! Happy Making!

    No, not by design, but you could hook it up to a ring modulator as the carrier signal or if you just wanted the reverb and delay, you could put a switching jack to bypass the function generator and plug in any sound you want.

    did you choose Korg as the lunchbox because of Korg and their synthesizers? or was that just by happenstance?

    that's absolutely why i chose it. I was looking for a space themed lunchbox, but when i found this, it was too good to pass up. :-) I hope to put together a kit similar to this soon.

    I got the korg joke. Does that make me a synthesizer geek?

    how did you power the whole thing? looks like dc from a wall converter. how then, did you get the -9v for the reverb?

    I just used 1458 op amps because that's what I had. really anything that makes sound would work. you could replace what i have here with an atari punk console if you wanted to.
