Assuming DOUT and Din (red traces on right side) are at 10ghz, Will emi interfere with electrode inputs on the left?

left input pin array is electrodes. right input pin array is spi, dout din , mcu connection

What kind of tube screamer is that?

what is a tube screamer?

Is this a bot trying to get people to do its EE homework?

 

[drgonzo1969]

stupid bot. If he would have lied and told us it was a tube screamer his homework would have been done by now.

Do you have a BOM?

You might find this helpful.

 

[tdengineer]

what are you guys calling me a bot? this is an EEG PCB this has absolutely nothing to do with tube screamer. I don't know what your guys problems are, im just looking for help on my first pcb from experts but apparently you guys aren't experts because professionals don't act like that.

Do you have a BOM?

im gonna make the bom after i finish the pcb becuase ill likely just be adding new stuff to the bom anyways.

EEG? As in electroencephalogram?

Unless it’s a brain-controlled Superfuzz (if so, kudos to you, sir!), you’re unlikely to find “professional experts” here…on the DIY guitar fx pedal forum…


* On a side note, can somebody help me debug the distorted repeats on my homebrew Defibrillator, or should I start a separate troubleshooting thread?

god dammit chatgpt told me this was a general pcb forum. it also keeps telling me im gay and I dont know why

Anyone here remember the Burst Box thread over at diystompboxes?

You'll have to excuse the responses, but this is a forum dedicated to effect pedals for guitar and bass, so we're musicians, not general PCB experts.

That being said a few of us actually are EE's and like looking at all types of PCBs. If you're wondering about EMI effects though we'll need to know more about the system, specifically your board stackup with thickness and materials, as that will significantly impact things. But as mentioned a BOM (preferably with a schematic) will obviously be helpful. Ideally a netlist for the layout as well to see which traces are going where. There are some great software options out there for analyzing stripline or pseudo-stripline designs for high speed applications, but even at my day job I don't touch things that go into the GHz range very often so I haven't touched them in a while.

I will caveat this by saying I am not an EMI/EMC engineer by trade so I am not an expert in the field of E3, but in my experience most of the people that are experts wouldn't be super helpful unless they're getting paid.

Welcome to the forum, whether you're here on accident or not
