It’s some real life quantum mechanics effect, I belief. The pots are always in superposition for as long as you try to check them and then only when you finally solder them that collapses the waveform — and always to the wrong orientation
Been there done that several times. I had boards made for a schematic that I translated into KiCad only to realize when I was putting the jacks and panel on that I completely did not take into account the height difference between thonkicon jacks and the standard 1/4" jacks we use for Kosmo. I felt like a complete idiot.
I still haven’t fixed it yet.
have a project in the works for these ?
Got an idea, nothing exotic, just a mic interface module, though unfortunately I ordered the wrong thing. Listing’s here and under “color” there are in fact two different, superficially similar designs (both purple) and I had the wrong one selected. Not that this one’s unusable but I want the gain control. So now I have some of the right ones — I hope — on the way.
Today I received the PCBs from JLCPCB of a quadruple envelope generator I’ve designed.
4 of these PCBs will be combined to one module. They can be used independently
or combined. The boards will be interconnected via a flatcable. Details will follow, soon …
If you intend to populate both U3 and U4, you may be up to an unpleasant surprise…
Per pcbnew’s DRC with standard footprints, these DIP packages
have overlapping courtyards. Pad separation center to center between #4 on top and #1 on bottom is a hair under 0.125".
mine IC socket type was more small on the plastic side
when i put an ic inside, it overflows slightly on each sides.
Lucky this time
This looks rather large. What are its dimensions?
100mm x 200mm. The active BusBoard is also the same size.
Today, I got some new boards, A multimode filter I have been working on for a bit, and some purple V2 boards for my VC ADSR.
A couple of my previous designs have been in my case and working well unaltered, so I am hoping to get these written up and published in the next couple of weeks, but first I have to finish porting my VCV plugins to V2
Looks awesome! I’ve been looking for a multimode filter with voltage-controlled resonance. May I ask, what is the filter topology/core of this design?
I had some ideas from a software filter that I have been repurposing over the years. Electronic wise it is a 4 pole ladder filter based on the AS3320, with the 4 poles tapped and summed to give various modes. I wanted to not use the default resonance as I wanted more character, so I used an LM13700 and some non-linear distortion switchable between symmetrical and asymmetric. As this is negative feedback for the resonance the filter response tends to zero at dc, so I have added some of the original signal back into the feedback path. Oh, I nearly forgot the first pole is switchable by an octave, an idea I got when studying the 303 filter design, although this sounds nothing like a 303 diode ladder.
I shall post some audio when I finish the build
Please do, I’m very curious! Sounds delicious
