For de-soldering i suggest using Flux and braid, dont use one of those sucking pumps, you will end up ripping of pcb traces if you are not careful.
Hope it goes well, patience!

Fates sharing same battery with Norns causing noise. I feed Norns ins Fate’s outs…
edit: seems to be the ground loop issue. so probably the solution would be 2 batteries…

Another option would be to adjust the lid for some extra height on the 3D print. This would make the buttons more flush to the surface but otherwise should be fine. Most pot shafts are tall enough that you can pull the knob caps up enough to accommodate.

Try shorter cables everywhere. Or you could make an audio cable with no ground, since the devices already share 0V.

Finally complete! Thank you so much @okyeron for designing such a thorough and satisfying project! The build is relatively straight forward. 0603 SMD were simple, I used this paste and a rework station. I had to reflow the DAC twice to get audio coming from both headphone channels.

Through hole parts came together nicely too. I noticed that the pins of the USB C jack don’t reach all the way through to the other side of the PCB. I assume that’s normal, it works fine. The rear post of the PJ302M2 jacks had to be sanded down slightly to fit into the PCB. The screen was by far the trickiest part, I had to clip several mm off the male pins to fit flush with the spacers. There looks like there is room for additional stand-offs inside the case, I might add these later to make it more stable (probably overkill)

The case I made was cut from 3mm acrylic, with a sanded finish. I got it cut from a local service but ponoko seems to have similar material. I used a Raspberry Pi 4, with copper heat sinks. No problems with heat so far. Instructions to flash worked great. Occasional SuperCollider fail message, but power cycling usually fixes it.

Very excited to dive more into this! I’ve only tried the stock scripts so far. I am hoping to build a Norns shield to accompany this in the very near future!

I really like that sanded acrylic case, that looks great! I think I might try that for mine. Nice build!

I’m just finishing up this prototype steel enclosure for the fates that I’ve been working on for @kasselvania. Laser cut steel welded up into a 2 piece construction. Soon to be powder coated.

This is one of five, if all goes well there should be 1-2 left for anyone interested. The steel is definitely on the heavy side. The enclosure comes to just about 2 pounds but there may be an aluminum version down the line if anyone is concerned about weight.

Just wanted to share some progress shots!

hmmm strange before setting up wifi awake was well…awake, now that i’ve set up my wifi i’m not getting any audio:/ also how do you ssh to the pi/ open a terminal?

hmm possibly raspbian?

there are some instructions for how to ssh into the norns in the norns documents that you can find here: maiden - docs: other access

waiting for a micro-sd card to arrive, but I think the assembly went pretty well :slight_smile:

Big thanks to @okyeron!

Dang. So I got my build together and I get no sound. Not even noise or hum. Quadruple checked the DAC, and everything looks good. I tried changing the jack buffer, but no dice. Encoders, buttons and display are fine. Any tips?

Had some sound issues with my new build yesterday. Sound cutting in and out. Solder looked ok. I gave it an extra scrub with 90% IPA to remove some excess flux I spotted. That did the trick. Maybe give that a shot?

Thanks! I’ll give that a go :crossed_fingers::crossed_fingers::crossed_fingers:

Check voltages. If the 3.3v voltage regulator is not working (bad solder or fried), you can end up with a no-sound situation.

No luck :frowning: Did a wash and scrub with alcohol and double checked the voltages. 3.3v regulator is working and the DAC is getting that 3.3v everywhere that it expects it.

To clarify - no sound from headphones or main outs or both?

I’ll try to update GitHub instructions with more troubleshooting info later.

Both. No headphones or outputs. Thanks for helping me out with this.

Conducting some heat tests today. Left Fates running with Raspberry Pi 4b for around an hour. No active cooling, but I have installed copper heat sinks. Inside the case the CPU topped out around 45 deg C running Awake, bottom of the case 35-37 deg C. Wondering if this update could improve performance further. Not running as hot as expected!
