Thanks,

I had to design new panel because I couldn't get bigger enclosure. When I printed it, I realized, there is no "trigger" button and it doesn't fit in "envelope section". Then I saw Dave Smith Instruments Mopho with "push it" button - so i decided to put "trigger" in the center and expose it somehow.

The knobs are really nice and small, and fit great in such tight panel. And are only 30 cents.

MANY thanks to Synthcube for the kit that made this possible. Once I started I couldn't stop. Easy peasy, built it in 2 days, basically. It might help that I was familiar with the circuit from troubleshooting another one, but there you go Smile

The audio is a triangle in, regen set to max negative and modulation by the LFO on its slowest setting, for the first minute or so, an then noodling with knobs after that.

Utility Distribution Module

Trigger/Gate mults and CV mults (including offset) built from MFOS CV/Gate distributor schematics (though I omitted the offset from one CV buffer), and Sum/Difference circuit found somewhere else. Built the three sections on separate boards and then had merry hell trying to figure out how to mount them on such a dense panel. Ended up building a stooge panel (?) from the flashing from Home Depot that others have talked about.

Not tested yet, but I'm pretty happy with the layout and wiring....

One of those lo-fi radio shack "voice recorder" modules ($10), set up as a looper. the rca jack goes to a foot switch for recording. the knob controls the supply voltage, which slows things down.

And a lovely case too. Do you have VCOs already to run through it?

Thanks! I've got a pair of Plan Bs just out of frame that I'm about to sell off. They will be replaced by a pair of CGS oscillators as well as a quadruple Utility LFO in the next week or two.

Subject description: Dronebox with 9 squarewave oscillators
Reply with quote  Mark this post and the followings unread

This is a circuit that I probably build 5 or 6 years ago, but I still had to put it in an enclosure. I originally planned
to make it into a cube shape (maybe use a photocube), but then I remembered this box I got not too long ago.
I expected it to be to small, but it was perfect! Razz

The circuit itself contains 9 (tunable) squarewave oscillators for the sound, and 9 (non tunable) squarewave oscillators
that together with some resistors, caps and transistors create a fading effect (both for LED's and sound).

It has a build in speaker + amp with volume control, but you can also plug in some headphones. I wired the output of the
amp to the tip and ring of the jack (sleeve not connected). So you can plug in a stereo pair.

The line out is actually a stereo jack that functions as a EFX S/R for the build in amp. So you can add effects while
listening through speaker or headphones Smile

I posted a recording last week which you can find here

and here's a video Cool

The oscillators are divided in 3 groups (of 3) and with the first 3 switches from the left I can turn the audio of
each group on/off, which makes tuning a bit easier. The switch next to those 3 is to turn the display on/off,
and the switch above the LED is the power switch.
