Trying to eliminate all possibilities, tried a different image on a Raspberry Pi 3b+ and the problem persists. Input voltages are fine. The electronic noise persists, but also seems effected by delay when running awake? Very bizarre, the scale demo doesn’t have any noise. Maybe worth trying @jmsiener advice tomorrow and totally removing/reflowing the DAC

Did some late night soldering :dizzy_face: removed the DAC, cleaned the pads with wick and re-placed the same DAC. Noise issue, is gone!! Seems to have done the trick

Just a quick update on my build :
I was using a regular Pi 3B and was getting lots of distorted sound even after when changing the jack_bufsize. I wasn’t sure about my power supply either (it was only providing 2.4A) so I ended buying a Pi 4 and 3A Usb-c power supply. Everything is now running perfectly fine, played a gig with it last week-end and I was amazed by the sound (Passersby) on a big PA :slight_smile:

I think this is answered somewhere in this thread already but sadly I can’t find it… (Apologies)

As the system stands currently, which is the best / easiest-to-set-up version of the Raspberry Pi for someone just starting out on this?

651

generally information is at : https://github.com/okyeron/fates
everything from building, to installing software

have you got the fates pcb/components?
if not, @okyeron shop is at https://denki-oto.weebly.com/store/c4/Products.html#/

have you built the fates board?
if not, build guide is here :
(https://github.com/okyeron/fates/blob/master/hardware/Build.md)

if its just the software, then its recommended you install via image, details here:

Pi3b+ should be rock solid. Pi4b is fine as well.

Sometimes with those fine pitch components there’s a little solder blob underneath that you just can’t see. I’ve done this loads of times in eurorack builds before I tried a different board/chip. Built an O&C once and noticed mid build that I had broken a trace or two under around an IC. Totally got the hot air gun and just moved each component to a new board. It worked!

I did some more reflowing and have noisy sound now! Also am getting the Awake Delay noise now too. Gonna try to remove the DAC and wick the pads tonight. :crossed_fingers:

Hey everyone - if you’re getting any wired behavior with audio etc. be sure to try a different power supply or different usb cable.

DO NOT try to power fates from your laptop USB ports. Get a dedicated power supply that does 2.5A or 3A.

i can attest to this. was powering from my mbp and finally realized that was the root of my problem. now the audio coming out of my fates is stable. a simple solution before taking more drastic steps. phewww

I ended up getting risky and reflowed with Awake running. I got it working and didn’t mess anything up!!!

FYI - I have created a new Fates “Commerce” thread and a number of posts have been moved over there regarding groupbuys, etc.

Lines forum rules state that “Trade” related posts need to be separate and kept under the Trade category.

This thread will continute for support/development/etc., but please direct any questions about buying, etc. over to that new thread.

Thx!

Coding and powering the RPi via iPad Pro over USB C – I didn’t realize this was a thing: https://www.youtube.com/watch?v=IR6sDcKo3V8
Apparently the OTG port functionality of the RPi Zero now exists on the USB-C port on RPi 4. @okyeron is this how you code things on airplanes from an iPad?

662

If you set your Fates into hotspot mode, you could SSH with an iPad using a terminal like this

Hi all - terribly excited to have some boards coming, and slightly nervous as between this and the Monsoon boards in my immediate future, I’ve got a lot to learn with SMD…!

Quick question on Fates - I’ve been digging around looking for 3d printing options on enclosures that I can sort myself. The only one I’ve found is this one, so would this be the best way to go? If there are any other options to consider, would appreciate the input.

Thanks in advance

664

Wow, that’s rad.

But yeah, as @dianus said, I had just been doing hotspot mode and WiF
(Which doesn’t always work very well)

I have older iPads with just lightning connectors so can’t test the usb-c otg functionality.

Has anybody successfully gotten an adafruit untztrument acting as a grids working with the fates? I have rummaged a few threads and can’t seem to find a definite answer.

666

Not that I know of. I’ve gotten the newer NeoTrellis M4 (8x4 pads) working as a MIDI input for Fates, and we’re all hoping @okyeron @TheTechnobear and possibly some others may be able to put some energy toward getting Grids behavior going using multiple NeoTrellis driver boards (4x4 pads) and a Feather M4 microcontroller.
Some discussion here, you may have already seen: Trellis M4 open source grid controller

Dang ,thinking I should have just put that 350 aud towards a real monome grid now rather than the Hella untztrument . :man_shrugging: Still hopeful tho ,there some smart people around here .
