yours seems much louder than mine!

Interesting, both of mine are pretty much the same! 1 is super early, no trimmer, some kludges, and the other is later, with trimmer.
You’re the third or so person I have heard mention having a quiet Pulse out tho!

at one point i was even going to message you on instagram to ask if there was a mod to bring the volume up a bit lol

edit: @crucFX, reading back through the manual and this bit is interesting:

maybe my silicon is just a bit quiet, or perhaps… too decisive :sweat_smile:

this is a bit of a general question but i want to ask this community - any recommendations for a good oscilloscope? would be cool to spend less than $400. is there anything specific about peter’s circuits that might steer a person in the direction of a particular scope?

I got an older HP scope off ebay for <$200 that works great. I see many people using the cheaper (<$300) Rigol or Owon ones.

I have a DSO Nano which is tiny and digital. Lots of options out there though, depending on what you need.

Have you tried the trimmer on the PCB? I had a quiet one, and after a few turns on the trimmer I suddenly heard all those lovely «vinyl» crackles🤩

i just tried, and it definitely helped!

previously, noise pulse out (knob full cw):

now:

still not quite as noisy as @crucFX, but much noisier than before! thanks, @T.Jervell !

If you can wait a little bit, due out in April (bumped up from December), The Korg NTS-2 seems pretty good for the money (~229USD)

I would not recommend this. Just get a 2 channel oscilloscope off of ebay, there are full size digital and analog scopes that are cheaper than this.

Buying a Plumbutter on Friday from a friend. Im wondering where’s a good place to start with this thing? There used to be a ‘manual’ on Patch Point but it’s off the site now, that link is broken. Anyone have any good intro points of reference?

Cheers!

Definitely also check out the original manual page too which is still up.

+1 on the DSO Nano. Pretty awesome to be able to carry around an oscilloscope in your front shirt pocket.

There are other handheld oscilloscopes aswell

What exactly is “rando” supposed to do? Here’s a video of mine working and I’m unsure if it’s working correctly. The frequency of the tone is influenced by the hairy cap and the x resistor sort of changes the pulse width. Input from a positive rollz node seems to turn it on and off.

Rando is supposed to be random slopes, but Peter never technically released it as a paper circuit because something about it didn’t work correctly if I remember right.
