Did you use 2 arduinos (essentially using one per sequencer) each with its own screen and I/O?
thanks for infos & the Barton vid link, i better understand now

like the color coding sections and simplified control labeling good idea .

Yes , that is correct. Seeing as the cost wasnt prohibitive, then I thought might as well build two at the same time.

Can you sync them / use them in sync?

My configuration is separate clock inputs , but from the same master clock source. I like to use a clock from trig out of from lmnc big button to progress a sequence ( less frenetic?) but basically they are synced yes. I,m pretty sure you could multi a single clock to each arduino though.

Managed to build my diode ladder VCF this afternoon. Haveāt had much time to play with it, but Iām really happy with it, it shrieks like a banshee and itās probably the module I worked hardest on - so Iām stoked with the results:
I put up schematics, BOMS and kicad pcb files here:
I did a whole bunch of reading and web searching to try and figure out the best way to do everything I wanted, so shout outs to:

I love your write up of the no-pcb version! Seems pretty inspiring to start twisting components and make something happen! Great work documenting the steps!

Heh - that wasnāt me, that was Juanito Moore - Iām not nuts enough to deadbug it and put it in a tin can, I just spent a lot of time looking at his schematic and pinching the bits I liked.

Sorry for the mix up, Iām still figuring out stuff here. It is a wild build with all those free-style components just hanging out there. Thanks for sharing the link and for your filter work, walking through your schematic now.

Hey,
I found an old effect pcb from the time when I was still scratching my 6 strings. This is the dead astronautās āChasm Reverbā, a really cool effect for long atmospheres and ambiant.
It is composed of a BTDR-2H brick from accutronics (which is 3x pt2399).
I have convert the circuit into an eurorack module:
I adapted the input and output levels for use with my modular; the idea come from the āstompbox adapter moduleā by Ken Stone (CGS60 - Elby Design). Then I just used a simple 12v to 9v voltage regulator with 78l09.
Here are some links:

I hope you have more fun with the Noise Toaster than I do with the Weird Sound Generator. It was my first ābigā project and I thought I had a device that you can really control and use musically ā¦ was not the case ā¦

I designed a wavefolder. In the video its output is shown when input is sinewave amplitude modulated from about 0.5 V to 5 V peak-to-peak. I managed to design it so that it uses only four op-amps, a one TL074.
I need to buy couple of trimpots to check some adjustments (like getting the fundamental signal a bit lower), but them Iāll post the schematic when itās ready.

That is a very very nice Foldermajiggy ! I love the oscilloscope wave !
Any chance you are willing to share your build info on this for your Eurorack version? (stripboard layout, wiring diagram, etcā¦)

Iām so happy with my kick drum, I will build any circuit you put out now. This one looks like a lot of fun too!

That loop is damn satisfying.
Krakenpine,
Iām looking with great interest toward more documentation and videos of this.

I would also like to know more - it would be interesting to pair this with my (watch this space) VCDO modules and see how it changes the sound.
I made a thread about that wavefolder, thereās more info and a schematic: My multi-folding wavefolder schematic
