so feeling confident after successfully putting together my own fates, i offered to assemble one for a buddy from a full kit. being the dummy i am, i soldered all 24 pins of the pi header onto the fates pcb before realizing that i had sat it totally crooked and terrible. :man_facepalming: a very humbling experience. i had a hell of a time removing the header from the board and damaged it in the process.

do you guys think this is still okay, or should i be ordering a new pcb?

hard to tell how damaged the pads/traces are from the photo. You’ll prob wanna test continuity with a multimeter.
Here’s the pin labels more up close:

The 2 you will want to worry the most about are SCLK/SDIN which go to the DAC (which might be fine since the traces go opposite of the board damage)

I was looking at rPi 4b’s and wondering, are there any performance reasons to go larger than 1gb RAM? I’d just be running standard norns scripts.

I just ordered a smd soldered kit together with the case. I have ordered all the parts except the display. I can’t find one with a reasonable delivery time under 16 Weeks or so. Are there alternatives or can you give me a tip where to find one with shipping to germany?

After you do a continuity check re: @okyeron’s suggestion, you might try nail polish (end-user’s choice of color, of course :D) to cover those “scars” and prevent unintentional shorts.

I don’t think there are any issues with nail polish dissolving traces or board material, but others please feel free to correct me if I’m wrong.

I don’t believe anyone has done any performance testing. For norns specifically I don’t think there’s much benefit.

Digikey has the yellow version

If there are only a few broken traces you should be able to fix with some bodge wires.

I was happily soldering along until I realised I had both headers on the wrong side :frowning: Made for a very unpleasant evening of unsoldering all of that, afterward I put it to the side and haven’t touched it since.

New kit arrived yesterday.

Boards all stuffed and ready to go, but hit a technical limitation - I’m running 10.9.5 on a Mac, and Balena Etcher requires 10.10… without having to upgrade my OS (major hump for a number of bits of software I use), is there any alternate way to flash the SD card reliably?

thanks

Just an update on my non functional right output.
Ordered a new DAC and dropped it on, but the problem still exists.
Except now I have a new issue. The sound from the apps won’t work. Samples play fine from the tape/ recorder section and dsp apps process the incoming audio, but synth engines make no sound.

So now I have a non functional right main output (both channels work on headphone output) and no sound from synth engines.

Any ideas?!

I believe PiBaker should work similarly, I have not looked at the requirements for the current release though.

Edit: looks like you can get the legacy version at this page if v2 won’t work on 10.9.5

Did you do further work on your case design? Would love to print this case!

#966

Thanks - had popped round to a friend (who had glacial internet!) and downloaded and flashed in the meantime, but downloading PiBaker now.

Still having fun tho - on powering up, nothing on the display… voltages check out at the test points, and I’m using an official Raspberry Pi power supply (with power going to the Pi3b+). Should I be expecting the Norns menu to appear directly on power up?

#967

Just a heads up, it takes a few seconds for the startup animation to kick off, even on a new pi 4b. I’d say wait about 10 seconds after plugging it in to see if anything pops up on the screen before concluding it’s not working.

#968

thanks for the tip - alas, has been plugged in for 30 mins, and no signs of life except for the LED on the Pi switching on… have also tried reformatting the SD card, and reinstalling the 3b+ disk image but still nothing on the display to get started with.

#969

You could always try connecting hdmi out and see if there’s anything that comes up during startup. You might be able to isolate whether it’s a software thing or a hardware thing from that alone.

just testing again - and have found a fault - tho have to find the fix now (further help welcome!)… Checking the volts again, realised I hadn’t checked the Pi voltage test point. I’m getting:

5v Test Point: 5.24v
3.3v TP: 3.296v
3.3v (Pi in TP): 20mV….

so the latter feels like a symptom!

Does the pi power up and run on it’s own? When the led comes on on the pi, do you get a red light? A red and green light? Do they blink?

Tested a few permutations:

Does that help?
