I feel pretty good about it. This was my first attempt at smd but I’ve been soldering stuff for a while. Yes, I do have a multimeter

I’ve only got one image allowed at a time. So bear with me please. I had to desolder the headers (lcd and extended pi)

From what I can tell, everything looks ok visibly, with the possible exception of R32 (Encoder 3 rightmost pin) on the left-hand side of the resistor, though it could just be the light. E2 looks good and clean.
If you have a multimeter, the first thing I would do is “beep out” (test the connections for) each leg of the encoder, along its corresponding trace until you get to the header (or the ground plane).
Without a multimeter, upon visual inspection I don’t see anything that would indicate a soldering problem. If you haven’t already, you could try to reflow all your encoder SMD components and see if that helps.

#813

I reflowed with a hot air gun (almost melted the headers) I agree with r32. I’ll trace back to the header. I may have just messed this board up.which - lemme tell ya - is thrilling.

Is there supposed to be a gap between c11 and c13?

#814

https://raw.githubusercontent.com/monome/norns-shield/master/images/norns-shield.png is high res for reference

#816

CAnt really tell what it’s doing.

Any chance you will have pre smd soldered boards back in stock?

Thanks man!!!

Looking forward to it.

#819

Hey tehn, could the problem with the flickering LED´s of the PICnome be using a Raspberry PI3b instead of a B+?

#820

nope. make sure it works with a computer. sounds like a power draw problem. try a powered usb hub.

and, whoa, picnome

#821

Hey then, thanks for your help. I‘ll try that.

also, out of curiosity, is particularly picnome creating that reaction or clones in general. I got it used to see if the whole grid world is something i want to have in my life. the original is still the goal:)

#822

ah, i was just surprised to hear picnome grids were still around

#824

Hello! I figured out my issue with my board and got it sorted. now I’m getting a super collider error - after restarting as the doc recommends in maiden/matron this is the output:

### SCRIPT ERROR: SUPERCOLLIDER FAIL

can anybody help?

Hi Everyone, I just got my shield working and I ran the update for the latest version of Norns - I’m getting the following error after restart/startup

" BATTERY: FAIL.

ERROR (i2c/hp) failed to write

This is right after a fresh SD card. I’ve verified that both the oscillator and the DAC are properly soldered/no bridges or bad joints. I can’t figure it out for the life of me. Is there a different image I should be using?

Thanks!

#825

run dmesg and see if the audio codec failed

there is no battery controller on the shield so that other message is fine

not sure what I’m looking for… I did the IC properly, I’m not sure about the oscillator - looking at the render in the git, I’m pretty sure I did.

#827

This bit.

The dac is not being recognized. Triple check the soldering on the dac, the RPi header and resistors in between the two.

#828

I soldered via hot air, I will check again - if pinning it out which pins should I follow?

#829

Here’s what I’m looking at.

#830

Hard to see but looks very much like dry joints on the dac. Also, suggest you remove the flux - it can very easily affect the crystal

#831

thanks, I went back and removed/cleaned/and reflowed the chip - would agree with dry joints. still nothing. there is a slight dent in the crystal, not sure that makes sense. tracing power back to the header now to make sure it’s at least getting that.

#832

I’d touch up the dac with the smallest tip you’ve got. You should be able to see solder flow. If you don’t, add a tiny bit to the tip, put flux on the pin and touch it again. After using hot air for countless smt modules, I generally drag solder if’s as it seems I get more controlled, reliable results.

Edited to add c16 looks like it could use a touch up as well.

Edited again, I would personally touch up a lot of passives on the board. Similar as i stated above. Hot air is really good getting stuff into position and works a lot of the time by itself, but I like the iron to finish it off
