norns shield

You’ll probably have to either post a picture of what kind of shield you’ve bought or try to figure the knobs out yourself. As that’s not the official shield, we don’t know what kind of knobs the builder has put on, or even which kind of shaft there is in the encoders he’s used.

There are two common types of knobs - one type has a tiny screw somewhere in the side and is removed by loosening it with a small screwdriver or hex key after which the knob comes easily off. The other is a push-fit so you can remove it just by pulling it out hard enough. There are also at least two types of shafts the Bourns encoders can be ordered with: D-shaft (half moon shape) and knurled (round, with grooves).

After you manage to remove the knobs (or a single knob at least), you can see what kind of shaft the encoder has, and order corresponding knobs from Thonk.

Ok, here goes, first really dumb question (of many): The monome website tells me to “press K1 and navigate to HOME”, then it tells me to “press E2 to select SLEEP”…but it doesn’t tell me which knob is K1 and which is E2. Can someone point me to a simple diagram somewhere that explains what is what please?!

K1 and E1 are top left, above screen
K2 and K3 are bottom left of screen
E2 and E3 are bottom right of screen

hope all’s well! there’s a diagram a few scrolls up from those instructions on play - docs.

did it not render for you? happy to help with more info!

Thanks @dan_derks and @cuberoo ! Making more sense now

somewhere in another thread i pointed to a fuse file system which could read ext3/4 file systems

haven’t personally used it but the op had success

many times have i used ext4fuse for this, fwiw

Hello!

I literally just ordered a shield and joined after a few days of getting my head round whats what. This thread helped answer a few questions, thanks to all.

One impertinent question tho…

There is a link to a US retailer for the appropriate Pi, charger, and SD Card. Does anyone have a link to a reputable UK seller with the exact right kit? The charger in particular seems to be a key component I dont want to get wrong.

I got my Pi from amazon simply because i had some credit to use up, but sourced the charger from https://thepihut.com/

thanks, thats great!

Pimoroni and Pi Supply are in the UK too. (Seeing the Pi is developed in the UK there’s probably an official store somewhere as well…)

Hi everyone,

With my norns shield on its way, I’m currently purchasing the cable adapters I’ll need to interface it correctly. I know it has a 3,5mm TRS for its audio output, but I didn’t read anywhere, so I take it it also has the same for input?

Thanks!

Yes, that’s correct!

Yes!

norns shield has 3.5mm stereo jacks (headphones work on the output jack)

Via norns shield - docs

Thanks guys, will go ahead with the adapters now.

Just got my long awaited Norns Shield kit but the screen seems to be dead. I’ve emailed Monome help but it’s a long wait until Monday! I’ve scoured the forum for possibilities so have tried reseating the PI, plugging into the wall, using a USB battery, different SD cards, flashing various Norns builds. Pi is not the issue as it boots via Raspberry Pi OS. It’s an official UK Pi power supply and a half decent 32gb SD card. I’ve SSH’d into Norns via Ethernet and all seems fine via dmesg, I think. I have a solid red LED and the other flashes for a while then stops. No start up tone. I’m not an experienced DIYer so think the issue is likely something I’ve done or purchased incorrectly. My screen remains resolutely black, like my heart. Any ideas on what I’m doing wrong or what I can do to further determine the cause?

what level of assembly did you perform on the shield PCB? SMT parts? headers only? or the latest fully assembled option?

we’ve seen lots of soldering issues on headers in this thread.

Ah, sorry, it was the fully assembled kit.

hm, then i’d think that assembly issues on the shield side are very unlikely.

hardware-wise, since both screen and codec are (maybe) not working, i’d still suspect the issue lies between the raspi PCB and the shield PCB - that is, in the header. if it’s possible to check continuity between the rpi pcb and the top of the shield header, that would probably be a good idea; a header breakout board makes this easier.

you can also continue checking things out on the software side: see if aplay -l lists the soundcard, post any specific dmesg output, etc.

for lookin directly at the norns software components, i do the following, with three separate ssh sessions (or screen/tmux windows); in order:

session 1:

cd /home/we/norns
./stop.sh
./build/crone/crone

session 2:

sclang

session 3:

cd /home/we/norns
./build/matron/matron

that will show you all the output, and in particular the sclang session will tell you more about why supercollider is (most likely) failing to boot. for me, the theory of a single point of HW failure is pretty strong.

also i’m sure dan will be happy to help you through the official support channels, but it is nice to not make him work on the weekend. :slight_smile:

Cheers for the assistance, very very much appreciated. I’ve run all those commands and there are no obvious (to me) errors although I’m not too aware of what I’m doing. Hopefully I’ve attached the lengthy results below -
