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".

cool !
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

LoL… looks like we had the same idea:
And after a long time I decided to buy a high quality DMM:
First impression: very fast and very accurate

The DMM looks very nice, is this just for Diy synths, or for professional use?
Its for DIY, not only synths, but also a lot of other electronic areas. I have 2 cheap Uni-T DMMs on my bench, but they have only 3.5 digits, can show values up to 4000, that means for example to measure voltages above 4V it can only shows 2 digits after the decimal point, or in other words in 10mv steps. This is very inaccurate to calibrate CVs. The Rigol can display values up to 240000 counts, and has a very low error.

More kits came in the mail yesterday and today:
Fred’s Lab Zekit - interesting as it uses some transistor optocouplers for CV control.
Now that I’ve got more than one synth I need some way to sequence them, so I got some boards and components to build this midithru-x2 from midisizer:
Hope to get building on the weekend!
Cheers

Another JLC order came in!
Included the BMC040 dual logic CV mod boards:
As well as these little Fresnel lens quad vactrols:
Fits together neatly:
Tried them out with a few different colour LEDs, must say they look pretty badass:
I ordered a few different types of photoresistors, will do some testing in the coming days.

These LEDs look awsome, cant wait to see them used in a module. You may find some of us asking if we can use the design and how to fabricate them, or if you are selling any.
