Yup! You can attach or remove these cases at any time.

I’ve got mine naked at the moment while I design a case and I’d suggest installing at least the 11mm standoffs between the RPi and the fates PCB and 15mm* standoffs on the opposite end. The top left spacer on the display helps too.

The reason I suggest this is the PCB flexes when you push the buttons, particularly K3. This could lead to solder joint failure.

I 3D printed some 11mm spacers in about 10min, as I have yet to find a local supplier for M2.5 standoffs. The display is the only thing stopping me from going to M3, a pain as I have an M3 tap and lots of M3 screws…

I don’t have a date for this yet. My thought was to do that once I’ve sold out of the initial run of boards (I’m about halfway through).

Just a quick question: Do I have to use the USB-C Jack for powering the RPi or can I also use the power jack on the RPi-board?

#828

You can use either, but do not use both simultaneously.

@coreyr
Thank you!

I finished the build, but unfortunately the Fates wont show anything on the screen. Is it possible to debug the RPi / Fates without having a screen?

That’s how my solder points look, I cant push them any further downwards.

#830

Screen position looks fine. There will be a gap there.

Check all your soldering on the display header and the socket - along with the RasPi header.

DM me pix of the soldering if ya want.

Maybe a picture of the top view?

#831

This makes me happy.

The whole process was enjoyable.
Now down to business…

Check you are using the correct image. Ie don’t use the RPi4 image on the RPi3b? I did this and got no display tell I installed the correct image.

#833

I made the same mistake, if its pi4 you need the pi4 correct image .

#834

My fate is sealed!

Thanks for all your replies.
I will try to flash the MiniSD again.
It’s definitely a RPi3B+, and I used the right image (I think so :smiley:)

I won’t be home for about a from now on, but I keep you updated if I find the problem.

So I’ve been having some issues with my recording input & output noise.
I’ve conducted the audio tests as suggested and everything is clean (bell tone, female voice, L/R channels) - except when I try to record and playback:

Record: arecord -f dat -vv -V stereo -d 15 ~/audio-test.wav
Play back: aplay -vv -V stereo ~/audio-test.wav

  • I can import wav files fine and playback is perfect, and all other apps + Orac playback is good.

  • It’s just recording external source via the inputs which is distorted (using zoom recorder and laptop for testing)
    I’ve tried numerous variables / cable types enough times by now to know something is amiss :expressionless: Any ideas, possibly a blown chip showhere?

#839

I’m probably just doing something wrong, but having updated to the latest Norns firmware, I can’t seem to do MIDI learn (key3) on my Fates. Anyone else experienced this? Thanks.

#840

has anyone experienced any erratic behaviour with their encoders? the 3rd encoder on my fates seems to be at its maximum and then jumps down to a lower value if i keep turning it. i reflowed all 5 pins yet it’s still happening.

You could also check the soldering of the header to the Pi. The encoder connects to the Pi through the header.

#842

I have the same behaviour specifically with enc 3 (it’s really unstable/jittery), haven’t had time to reflow or investigate yet though. I’m not sure there are pullup resistors for the encoders on the board, so it might come from that but then all encoders would be affected… :thinking:

#843

May depend on the script - what are working with?

There are not. The encoders go directly to the pi GPIO pins

#844

hmm i’ll reflow the 2x20 header and see if that changes any of the behaviour. thanks!
