Ciao purtroppo non sono a Roma. Più di spedirmelo non so che dirti. Dove hai avuto problemi?

#1905

beautiful case :slight_smile: do you know where I can find the file for 3d printing?

#1906

Is this fixed ? Thank you

#1907

Hey Everyone,

I installed some scripts via ssh this afternoon and when i tried to launch them FATES said “error : suppercollider fail”
I tried to clean via maiden the files and uninstalled the scripts but it still doesn’t work. I also followed the “restart” in matron but it doesn’t say anything.
What can i do ?

EDIT : Nevermind I disconnected it from the power supply and it worked again.

#1908

Not yet fixed in the fates fork. Was waiting on the next norns update cycle.

I’ll try to look at this in the next couple days.

After plugging my Fates build in today, I found that I was having encoder issues… but only on the right most encoder. I can’t think of anything that changed but after looking at the encoder outputs on a scope, I noticed a LOT of switching noise coming from those encoders.

I pulled out some 0603 0.1uF SMD caps, soldered them in between the pins of the encoder, and tried it again.

And now that encoder is not having any issues at all!

I’m not sure if those are the best values, but they’re good enough for me to not have the volume of Haven glitch to 0.0dB and blast my ear drums.

I’m about to do the same to the other encoders now even though I haven’t seen issues on them. Switches get dirty over time and the SNR in our world is only getting worse so filtering sounds like a reasonable addition to any Fates build.

I included shots of my power supply, the parts I used, and my best attempt at the solder job.

I hope this helps someone!

EDIT: I should add: I was able to add these to the bottom of the board because I was lazy and didn’t trim the leads. BE CAREFUL if you need to do this on the top of the board! Don’t overheat those encoders!

Nice hack!

I’ve got 10n caps for filtering on the encoder of a recent project (based on the encoder datasheet I think?)

Smaller would have been better. I had no 0603 10nF caps.

#1912

This is wonderful! Thank you! My encoders are silky smooth and error free now.

#1913

This should be OK with «regular» sized ceramic caps as well right? I have a small stock of different values. Will try as soon as I have some spare time.

#1914

You inspired me! Put some 0603 caps in to the jumpy encoders on one of my fates, very happy with the results and now it’s time to do the second!

Nice work! Do you have a mouser part number? Would any 0603 0.1uf work? I.e. does it need to be around 16v

#1916

prob any 100n will work just fine. 16v and up is usually good for the 5v system

(apologies for this being a “problem” - just never had a chance to fix it on the board)

Thanks, and no worries - you’ve done amazing with with Fates. The 100n hack worked on my encoders :v:

#1918

Hi everyone
Has it ever happened to someone that the Fates remains on this screen when turned on and that you have to turn it off to start it up?

in my case, having installed sidekick, it was enough to keep the three softkeys pressed simultaneously. but I would like to understand if this can happen at times.

Thanks

#1919

The only think I can think of is that the systemd units failed to startup for some reason.

you’d probably need to do some system log checking when it happens to see what might not be running.

systemctl status would be one way to check.

Just wanted to thank @okyeron again for this wonderful project, and helping so much with everything.

And I also wanted to share pictures of my two fates (one is still in the cardboard prototype box haha):

One is 1/8" walnut, the other is a USPS medium flat rate box. Knobs are some cheap ones I found on Amazon.
I used @okyeron’s drawings from the acrylic case design as a base.

I’m using the raspberry pi 4 4gb, with cheap heatsinks and no vents on the case. It runs a little bit warm, but I think it’s acceptable. Highest I’ve seen it is 67°C (what it reads on the norns software).

Had some time to solder on some 15nF caps on my encoders as well. Now they are all smooth as butter. Essential hack!

Thank a lot for the image! Very helpful for someone clueless like me.

Can I use these?

I think I will also have to do something about my jumping encoders…

#1923

Should be ok!(somebody correct me if I’m wrong). And happy to help! No need to solder in parallel direction like I did, did it mainly to conserve space(and to simplify soldering).
