Bumping thread from this past summer ... Just tried this, and it's very nice for super ambient stuff. I would love to expose all 30+ parameters of CloudSeed. KNOBS.

Ok, I think I understand where you are with things. There's a thread in here somewhere where members have posted their setups. I think you'd get lots of ideas from that for how to layout your work area and workbench.

I have little yellow plastic trays that I save from H-Mart. They have a number of packaged produce items (eg jalapenos) that are in trays and covered with cellophane. Perfect size for a pedal worth of parts. Not a full solution to your problem by any stretch, but I find it helps keep a...

Very nice. Thank you for sharing this. edit: Just tried it out. Works great!

I recently acquired a Doom 2. I love the synthy tone and touch-sensitive response ... it's significantly different from my Bass Big Muff Pi, for instance (A reasonably standard reference for bass fuzz, I think?). The Doom 2 is designed with the preservation of bass in mind, and I'd say...

Every participant I've encountered on this board and the Daisy Slack has realistic expectations with regard to first steps. We've all got to learn to walk before we can run. This is a very collaborative, supportive community and there are only solutions and good times ahead, as far as I'm...

Looking again, I also really like the knob choices here. The black knobs hide the dominant "V" shape of the layout. Instead, we have a subtly framed diamond pattern of silver points. Very appealing.

If I recall correctly, there's a thread around here where it's recommended those LEDs be replaced with some capacitors for better shaping.

I hear 1KHz loud and present using either my 30 dollar supply or my much nicer CIOKS supply. I'm not aware of anybody decidedly solving this issue for general usage, as all of the 1KHz noise threads I've seen on the Daisy Slack appear to be unresolved.

Love the flying whale. Is that a nod to Gojira?

I like the woodcut(?) print you've used for the graphics. Good idea.

Sounds good, and nice idea with the rubber stamp. I like the aesthetic: in some alternate universe, I might find it at an army surplus store.

Nope. Only sounds OK if I use it as a passthrough. Another very specific thought I had to salvage this pedal was to use cycfi's very efficient "bitstream autocorrelation" pitch tracking code to drive the cutoff frequency of a lowpass filter, and tack on an analog lowpass to remove >= 4KHz from...

I'm thinking of converting this thing into an audio feature extractor and CV generator if the noise issue can't be resolved.

I'm not currently using the debugger. It's always present and loud with the filterbank I'm messing with. Going to strip it down and make it much more simple next.

I assume it doesn't happen with the passthrough because in this case little work is being done by the STM32, therefore current draw remains relatively constant during the callback. As a result there's relatively insignificant lift in the GND signal, thus no audibly apparent induced 1KHz noise...

Yeah, I didn't notice it with a simple passthrough, but I did when I set up a filter bank of state variable filters. At first, I was hoping that I had accidentally set a few of them to self-oscillate, but that wasn't the case. I hope to have some time to mess around with this soon.

I haven't looked at the problem and associated constraints closely enough to really know, but I'm wondering roughly how many likely groupings of "parameters + display indicators" there are. 3 groups? 5 groups? 99? ... Clearly there's a huge number of possible combinations, but I would think...

Looks slick. An optional CV out could be interesting. Pads or headers to expose GPIO that aren't otherwise occupied could be a nice feature for miscellaneous additions.
