What is the input to Fates 1? You may need to attenuate the signal (w/ a mixer)? Perhaps the audio signal is too hot coming out of the rack?

Also - in your picture, you don’t have an output connected on Fates 2.

Which unit has noise in this situation?

#699

Had similar issue ( Norns Fates) due to being powered from same plug. Cable length also matters

#700

Can you clarify which “same plug” you mean here?
Both USB power supplies on the same power strip? Or…?

@kasselvania hard to tell from your picture - looks like power for both may be coming from a USB hub? Maybe try different power sources and see if that changes anything?

#701

I ended up trying a few different things, to middling results. What I ended up doing was just changing the Compression settings in the main settings. Was able to find something that would limit that.

#702

Since we’re kind of near the topic… which power port should we be using (RPi or fates)? Either? Both?
(edit - should have specified that I have a 3B+)

#703

Either - Yes. Both - absolutely not

(edit - for the Pi4 I’d suggest sticking with the Fates power input because it’s got the right resistors to work with e-marked usb-c cables. But… on the other hand if a cable does not work in the rpi power jack, it will likely work OK in the fates power jack)

Hello,

On the shop ,I have notice an I2C adapter.
Is it really I2c protocol or just a plug conversion type ?

Is that part of a special firmware ?

#705

No i2c protocol on Fates.

That adapter is just a simple minijack to jumper adapter. Useful to jumper 16n directly to a module or busboard.

#706

what I meant is when I powered both norns and fates from the same multi plug power scoured there was noise, think it was the ground loop issue.

#707

I don’t know if you already checked that, so it’s just an idea. But when I had an OP-Z it did spread a lot of noise via its USB connection and was barely usable in my set up.

#708

Separate question: did you cast a concrete monitor arm base? because that looks awesome.

rPi, and soldering gear arrived yesterday. Friend who knows how to solder and can help me arrives today. Fates will hopefully be working this weekend and I am beyond thrilled - and im sure ill be up in here posting about it soon enough.

I WISH! That’s a beautiful lamp a friend gave me for Christmas one year. My home has gotten a bit over run in the last year or so and it’s getting relegated further and further back. I will often pull it out for a little extra lighting doing some late night work though.

I’m shocked I posted a pic of my desk, since I am overrun with work (and thus wired and equipment).

On the FATES note, I believe there’s a few issues with my FATES 1 board as it was my first build. It might be worth reflow if the board in the next day or so and seeing if that corrects the issue.

Finally got some time to solder the board, I love how smooth it was. Up and running now, love how the look matches crow! Thank you so much for all the work you put into this @okyeron.

I’ve been having some trouble recently with Fates locking up. I usually power from the USB C on the fates PCB, but I noticed sometimes I will get a red power LED but no activity. It sometimes helps to try booting it from the Raspi side USB mini connector (3b+) Today I can’t seem to get any life from it. Ideas? I’m usually very careful to power it off correctly.

#713

Try different usb power cables or power supply if possible. This seems to be recurring theme for troubleshooting.

Also be sure the sd card is properly seated in the pi. (If not, that could account for the lack of activity lights)

Hey, just a quick question about the through-hole BOM:
I ordered the whole project from Mouser, that the PEC11R-4015F-N0024 Encoder will take some time until it is ready to be shipped (estimated March 2020, lol). If I would want to order an alternative, what are the specs I should look after?

#715

https://octopart.com/search?q=PEC11R-4015F-N0024&currency=USD&specs=0

#716

PEC11R-4015F-N24 is a flatted shaft, 15mm length
PEC11R-4015K-N24 is a knurled shaft, 15mm length
PEC11R-4020F-N24 is a flatted shaft, 20mm length shaft

check the data sheets on those and compare specs if you go looking for another brand. Resolution: 24 PPR is probably the most important spec item (aside from size).

#717

Hmmn just tried 3 different supplies and re-seating the SD, no luck. Do you think re-installing the disk image would help?
