My build progress

Yes, that’s why I said “full writeup soon”.

Added: Voltage controlled all pass filter

you going to do some analogoutput videos on you tube about your new stuff ?

Sometime before I die.

(I just realized of the 5 new PCBs, 4 of them use only the board mounted 1/4" jacks to mount the PCB to the panel — which means you now hate me. Sorry!)

just have to drill and use stand offs , not to the point were I will venture into redesigning the boards . my first order of pcb’s is on its way [ your joy sticks ] thanks again for sharing the knowledge .

making two of them , not as big as its looks in picture ? about 90cm wide x 60 cm tall . will be about 25 cm deep with cover on and 20 cm cover off . yeah kind of largish [ portable cases lol ] .

I approve of your use of failed panels. I’m assuming that’s the one I designed with the Druid PIC in it?

Yep! Works perfect. Mixing modulated noise on top of a clean sub from the VCDO sounds incredibly fat.

Have loads of spare panels since you need to order 5 at a time from JLCPCB, handy for putting stripboarded stuff behind!

That sounds like a good idea, I might have to try that.

Geräuschzeug find ich prima ! Ist einfach und man merkts sich, mir fällt immer nur so komplizierter Mist ein :slight_smile: . By the way, grüße aus Kassel


Proof of concept of voltage controlled tubescreamer-type overdrive. I can control the gain directly with voltage, not just having vca attenuating signal before the diodes-in-a-feedback-loop-op-amp, as that sounds much worse than adjusting the gain. And I still haven’t managed to make a working circuit on a breadboard. Something is always loose, and if it’s the power supply pins, something can break as some chips really don’t like having input voltage higher than their power pins.

Yoooooo, hell yes. Eagerly waiting for the schematic/stripboard layout of this one. I love your kick so much, I’ll make anything you design now. But Mr. AO is going to want to see some bypass caps on those chips!

Got a link for that design? :smiley:

It is a modification on this design:

I will get my modifications uploaded somewhere. Mine works for 1/4" patch cables and requires a larger printer to print the 250mm diameter circle.

Some resistors and some flux today, it’s a start.
