well that’s fineish, as long as the pin-package designation matches. it’s just a bit of space conservation…
off to JLC for the 30th time for the midi filter… Fingers crossed.

Why the heck is the GATE not working?
Oh… That’s why , stacked in reverse… Good job this jack board is not even vritical.
We have mess up thread?? How have I missed this!
A day ago I ran two jack outputs from my volca beats for snare and kick as a test, but there was huge him and they acted super weird through a mixer. I thought I mixed up ground and signal on the jacks. So I rewired them and they worked!
Then I wired up the rest of the jacks… Now nothing works. Some of them work when they are the only thing plugged in, but plugging in another jack makes it go silent. Some only work if plugged in half way. Totally baffling.
Then I looked it up and I think this time I mixed up signal and ground and that I had it right the first time… So I don’t know what the problem was initially.
Going to try again tomorrow… But this is an extremely simple thing, I don’t know what’s going on

So I built the 1 Song by Barton. I finished all the wiring and soldering and was all excited to test it. I quickly shoved all the IC’s into the sockets and went into the other room to plug it in. Soon as I turned the rack on I noticed the magic smoke escaping from the 10 ohm protection resistors. After chasing for a few hours with a multimeter I decided to post the question on here. Well member @craigyb noticed that I had swapped the TL074 and the PIC. Very lucky the PIC didn’t smoke. Let this be a lesson boys and girls. Don’t rush to plug in that new module. Check, check and then check again. Thanks again @craigyb .

Not really sure which is worse, having a module that doesn’t work and you can’t figure out how to fix it, or having a module that didn’t work and now it does and you can’t figure out how you fixed it.

#1. absolutely #1. at least #2 has a magically working module.

But for #2 you’re forever cursed with the insecurity that it might stop working again…

#1: You may have learned something even if you didn’t fix it.
#2: You are still a dumbass.

I mean, as option 2 is happening to me at work quite a lot of times, dumbass is a bit of strong statement… what about, “you will get another chance at fixing it” ?

Only if it breaks again. #1 gives you learning opportunities forever!

Please stop describing 90% of my code at work.

The schematic I drew says side adjust trimmers.
The PCB layout I made says side adjust trimmers.
The BOM I exported says side adjust trimmers.
The spreadsheet I filled in says top adjust trimmers.
Guess which one I relied on.

Oh so THAT’S how it could possibly not work
i found side adjust trimmers too expensive. so just bent a regular one over to save a few pence

… “OK, that should fix it.”
“Gonna test it?”
“Nah. How could it possibly not work?”
“…”
“Oh all right. … Huh. Oh so THAT’S how it could possibly not work.”

Here’s a tip:
When working on a design, or after working building something for a long time, where your concentration may be suboptimal… take a break. Avoid the temptation to rush things.
Have a coffee. Take a walk. Maybe even go to bed and leave it until the morning. Then check everything with a clear head.
Sometimes mistakes you missed are easily spotted then.
Also. I try and use IC sockets if possible, and check the supply voltages on a live PCB before inserting the chips. The right way round.
