I'm on vacation this week so I thought I'd do stuff I don't normally have the patience to do!
I haven't done any serious electronics in about 7-8 years, aside from bending a few things and adding pots and plugs. I cranked out some notes and made this simple little project. It's more or less a dual-555 pulse generator with vactrol "lfo" attempt. For now I'm just calling it 'Plankton I' though. The four knobs are volume, lfo-pusle rate, fine pitch, and main pitch. The lone switch on the side switches between 'tinny' sound and 'phat' sound. The switch next to the 1/4" is just the power. By adjusting the fine pitch and lfo-pulse simultaneousley one can get some neat phasing/etc effects (like between 0:10-0:30 in below sample).

I need to find an embossed plastic labeling thing for labels on this, otherwise I'm done! It sounds pretty good run through my guitar pedals too.
I want to make a better one when I have the time, something with sine-waves and more bass and features/control! | |

thanks guys!
although the second 555 I label as an lfo, it doesn't function like I had planned. it does produce a neat side-effect though, different from simply mixing two pulse oscs together.
yeah the 1/4" is line out. power to the speaker is cut when plugged.
I started it tuesday afternoon, buying components in bulk and only having a vague idea what to do (multi-555 sound generator where one modifies the other). built two generators side-by-side on the breadboard based on this design: link (without the optics). had the output of one operate a vactrol that in turn modified the pitch of the other, and changed/added diods, resitors, caps and pots in a few places for greater flexibility. experimented with values and routes. ended up with: link ..then the next day I soldered it to a PCB. I'm not that good at component placement and optimizing routes and all that, hence where there are jumper wires all over it. :
2-3 hours for the test on the breadboard, and about 5-6 hours half-heartingly (while watching movies/doing other stuff) building the permanent thing with casing.

thats cool
UI'd be interested in one that works on sine waves
anyone who wants to create an audiobulb version of such a box - get in touch  i'd buy 5 or 10 from you and sell them in the abulb shop as a "release" - the Root of Sine drone box for example....

nice looking inside and out.
also, is it acceptable to have a battery (coil+iron=magent) sitting on top of the speaker (magnet)???
probably has little effect. nice...
