Rebooted with all USB MIDI cables removed and all seems fine now.

Maybe cd .. at the end, to avoid the (potentially heart-wrenching for new/inexperienced users) error retrieving current directory: getcwd: cannot access parent directories: No such file or directory errors.

#1283

like where? after ./update.sh ?

I didn’t get this error, so… confused.

#1284

Weird… yep, after ./update.sh.

EDIT: at the end of update.sh, we have rm -rf ~/update/*, so if the script is running from ‘~/update/200218’, one would get errors. I do see that just prior to that, we’re doing cd /home/we/maiden + other stuff, so theoretically, we should still be in /home/we/maiden, but I Am Not A Bash Expert, and bash is weird and fickle :stuck_out_tongue:

EDIT: Honestly, it’s probably just me. I have a lot of prompt stuff going on, and tons of aliases and functions in bash’s environment, so it’s likely that there’s a race condition between where the script thinks it is and where bash thinks it is etc…

#1286

All done (bar the screen cover).

@okyeron can I suggest you make the hole for the power LED at the front of the case into a slot, to also show the green disk-activity LED?

It’s good to know when it’s safe to unplug the box.

Good call. Thx for the suggestion.

I had added a double hole to my norns shield box design, but had not updated the Fates case layout with that. I’ll try to get that in there for the next batch.

#1289

Cool :slight_smile:

Might also be nice to include a few more screws and spacers for the other side of the RPi. There are holes for them in the bottom panel of the case, I notice, but nothing to screw into them.

#1290

In practice I don’t find it necessary to support the pi on that side because the pin header is already holding the board in place. I left holes in the case design if someone wanted to add their own spacers, but was trying to reduce the case part-count/cost (those 3mm spacers are actually kinda expensive)

I ended up 3d printing some spacers, but it might be worth trying to laser cut some since the case is already 3mm. Could probably fit a bunch in the waste from the screen cutout.

I built my fates last night, at the beginning it work fine, thus it got silence in several boot, then I realized it would happen if I plugged my MIDI twister fighter and a keyboard. However after 3 hours of playing the screen got flickering and eventually will black out. Strange thing is I let it rest for an hour, power it up again and it became normal for several minute and then black out again.

Any thoughts? Where I should inspect at first? Thanks!

#1293

My first question that might help is: how are you powering your fates? What is the amperage rating on your power supply?

What script were you running on black out?

Is your screen fully seated in the pin headers?

As far as usb midi externals, I usually plug them in after powering up my fates. Digital hardware can be super power hungry on boot and brownouts can cause all kinds of issues. Plugging in usb midi devices after boot can reduce power strain on your power supply. At least that’s how I understand it, and I’ve had less issues in boot that way.

#1294

I have tried several PSUs to power the fates, after I used the original norns PSU to power, which is 5.25A

The script I run is awake (I did the disk image again accordingly in my 16Gb micro SD with FAT32 formatted, tried to exclude the potentially software problems)

By look it seated well, but I am not too sure.

#1295

Almost sounds like a thermal issue…

#1296

You might check to see if you’re getting undervoltage warnings. dmesg from the commandline (over SSH) should tell you. Or if you see the red LED flick off and back on, that’s likely a power issue.

I don’t think I’ve seen the issues you’ve described.

As others have said, check your power supply or cables. The official norns PSU may not actually provide enough power for a RasPi. Are you sure it’s 5.25A and not 5.25V with some other A rating? (5.25A seems like an odd number for amperage to me).

What about the power cables (if separate from the PSU)?

Which Pi are you using? Which power port are you using (Raspi or Fates)?

For more debugging, run without a case for awhile and if things start to get flickery again, touch around the Fates board and see if anything seems hot to touch (it should not be).

Triple/quadruple check your solder joints on the display headers (all sides).

#1297

Thanks! Will try the dmesg tonight.

Not sure about the status of the LED, will pay attention to this in future test.

Probably I mess up with V and A… Sorry.

The power cable is Anker, which I use it with my Mixpre in studio, I think it is alright.

The Pi is 3 B+, I detached it from my pisound which I am using.

I think I will re-solder the joints on display.

Thanks again.

#1298

in fact it is 5.25V at 2A.

@okyeron’s troubleshooting sequence seems spot on. if something is overheating then it could do what you describe, and it is certainly an assembly problem.

#1299

Finally received my acrylic kit. Had some good luck using nail polish on the etched labels to make the back a bit more legible

The nail polish stains the matte finish a bit, so it’s helpful to have both a color and white, so you can use the white nail polish to tidy up the smudges

Did you end up adding a battery pack to your FATES case?

#1302

FWIW, I used colored Sakura Micron pens (very forgiving and easy to “erase” and start over), the finest tip I could get, when I did my Anushri (link to flickr).
