That looks great! Is that some kind of plywood? What kind/thickness?

Hi. I had a Norns. Now I have a Fates. I’ve got things rolling along pretty well. A few questions/observations:

  1. Is Vials running for everyone? I get error: load fail.

  2. I think someone mentioned this up above, but when I have two USB things plugged into my Fates before it’s turned on, I’ve received a supercollider fail message.

  3. I haven’t used my 16n via i2c with my Fates yet. Please remind me of the power-up sequence. I don’t plug a powered-on 16n into a powered-on Fates, right? Thanks.

  4. Has anyone had luck connecting a QuNexus directly to a Fates? Mine isn’t being recognized. It powers up, but doesn’t show up.

Here’s a quick snapshot:

I think I posted a fix for this above? Or you will need to do a git pull. But then you need to replace a norns source file to get compile working. (I can walk you thru that. Need to write a script for this)

Immediate solution is to unplug your midi devices when you boot.

This is not possible. Fates does not have i2c connections. 16n is midi over usb with fates.

Thanks! I’ll read up on the supercollider fix.

Ah, yes. I misread the Pi’s audio out. :slight_smile: California dreaming.

Correct. (I think) it is 6 ply birch plywood, 3mm thick. Super high quality grade. Got it at the communal workshop where I laser cut it. One of the more “expensive” materials I could get. But 100% worth it.

so you need the file and a laser cutter? is the file the one posted here? thanks

#555

Yup. Correct. I made some tiny modifications to the file(removed anything related to having a fan). But any 3mm laser cuttable material should work without mods to the files.

There are a few variations of laser cutter files on the Fates GitHub.

I had to make slots a touch bigger for some material that was 3.25mm in some places instead of 3mm. So In practice you’d want to get a micrometer on your specific material and adjust holes as needed.

I ended up doing a test cut of a corner(with some engraving as well) to see if everything fit.

I’ve been thinking about what to do regarding the case for my fates (definitely putting the horse before the cart as I haven’t built it yet), and the idea occurred to me to protect the screen by cutting the top layer out of two different 1.5mm acrylics-one opaque, one clear, with the clear one not having a hole cut out for the display (then sandwhiching them). Is there any reason why this wouldn’t theoretically work? I might give it a go, but unfortunately the laser cutter at my local hackerspace is out of commission for the time being.

EDIT: Thought you were doubling up on 3mm material. Disregard.

The knobs and buttons wouldn’t protrude far enough. You could get around that by making large clearances around those features on the topmost layer.

The tabs from the side pieces would need to be longer to engage the doubled-up top material. As would the top screws.

Overall I think there are better ways of adding a screen cover, but your solution could end up looking pretty cool.

If he is using 1.5mm acrylic for the top sandwich, it should work fine. 3mm is the total thickness.

#561

Whoops. Yeah that would work fine :+1:

I’m having some trouble with sound output—everything seems to be wired up properly but I can only get sound playback when I go into the menu to play individual samples. Tried a few sleep cycles, I’m thinking about re-flashing unless someone has another idea.

#563

What scripts are you testing with?

#564

I’m having a strange sound issue. I just built my fates, and the build seems to be fine (no obviously bridged joints, etc.). I flashed it fine, and it powers on and plays scripts, navigates the menu etc. But when I plug headphones in there’s only awful harsh noise, which changes as I move around the menu. I double checked the board for problems, but I can’t see anything wrong. Is there some software issue that could be causing this?

edit: out of curiosity, I booted the system without the SD out of my pi and, of course, nothing happens, but no harsh noise. When I use the raspberry pi’s power slot it’s different, still a lot of noise, but less harsh and I can kinda hear the audio from awake.

#565

Just Awake and the scripts that came loaded with the disk image. @cwil I don’t have harsh noise, but I don’t quite have silence either—sort of a low roar I can affect with the system audio params.

#566

This sounds like hardware, but I’m drawing a blank on what to check. Be sure all the 220R’s are good? Can you post a picture of your soldering?

Hold up - what happens with the main outs?

#567

Check the levels on the MIX page. Eng may be turned all the way down?
