I changed my post here in the thread, the pictures are now clearly labeled “UNVERIFIED” and I also posted them again in the new unverified thread that @willow2x created
Joystick schematic and CV Wheel schematic come from Niklas Rönnberg
I change 100K to 150K on range pots to have +&- 9V out max (before i have 11,80V)
I add a trimpot on the wheel schem for best octave adjust.
Not a complex board but a lot of spaghetti
EDIT of the Layout
I’d encourage adding a BOM to these layouts.
Are these pots from the front or the back? I’m just getting a lot of noise.
i think it’s from Front, because generaly to decrease = more signal to GND = GND on the pin 1 of potentiometers
(here it’s 1 and 2 if i look at the other stripboard down, the Cusi one)
Damn, that’s what I had. Doesn’t explain the all the noise. LED lights up as expected, but the buzzing is crazy. Is there a ground wire needed somewhere that isn’t labeled, maybe?
To be sure you speak about the Hit noise percussive module ?
Yes, the first one, using hi-hat cap values.
I think they’re from the back. On the layout of Cusi Sound, definitely from the back.
You can find it exactly in the corresponding videos, or the video descriptions, I think the schematics are definitely there too.
Are you sure ?
look on the original schematic it’s pin 1 & 2 to GND on the pot.
like i said to decrease a signal with pot, turn to left so to GND
No, I’m not sure, but now we have the solution with the schematic
In any case getting it the wrong way around won’t make the circuit not work, it’ll just make the pot work backwards.
@BlackDeath, what problem are you having? Noise, but it’s supposed to be noise. Can you post a recording? Photo of your board? Maybe discuss over here Easy noise drum so this topic can be clear for presenting stripboards.
I got it working! A little noisy, but that’s okay. The issue was my stupid "2n3904"s that were actually 557s… just switched them around and it works!
My first stripboard module! Yay!

Good to hear that it wokrs now, the sound example is great !
I’m liking the white noise it makes, I could use that to layer on top of a drone, does anybody know enough about the circuit to suggest where to hack in an output before the envelope stage?
Hey great job !! Have you mod the monotron duo ?? I want to mod myself for eurorack but I dont find a lot of documentation. Thank you !
