yes. personally i’ve found it plenty loud with low-impedance cans (e.g. ATH-M50x, 38 ohms) but not with high-impendance ones like DT770 (250ohms.) ymmv of course. (i’ve measured a number of earbuds lately and found that they sometimes have very low impedance - 24 or even 16 ohms! - but the transducers themselves are less efficient and less linear.)

if you need it i would consider building or purchasing a small burr-brown headphone amp. they are inexpensive and make most things sound better. (plus i just like always having an analog level control.) these days there are a lot of models that include a rechargable battery too:

probs best to stick with the image up top rather than building. if you’ve got a router, internet & a spare ethernet port here’s what works:

power up
plug ethernet into pi & LAN port on router
on wifi screen you should see ‘wired connection 1’
update ! it should work !

i think this is becuse the the file you installed is for the “regular” norns and not the norns shield, do as andrew says, use the DIY: norns shield image, and update inside of the norns itself, you can share internet trough ethernet on both win and mac pc’s, plenty of guides on the interwebz.

Try looking for another colour?

#219

muchas gracias, tried doing this while not at home without a router. Got home and it worked out.

#220

any issues plugging mono cables in and out of norns diy? mainly for convenience with other gear/mixer.

Oops. I’ll update the post, but it’s for 3mm (1/8in)

Can we get a version of norns for the shield up-top with working wifi? I don’t want to buy a usb->ethernet dongle just to connect to my norns so I can select “update” over ethernet :sweat_smile:

ICYMI ->

normal ethernet cable + router also works. got mixed up about that as well

#226

I haven’t owned an ethernet cable for years, as I imagine some others may not as well. But thank you, a new image would be a big help.

#227

apologies for the delay… i’ve got to dig up the magic commands to export a disk image here (weirdly more complicated than the actual norns as the disk size is variable)

I can get an image up on Monday night (apologies, not at the studio)

in the meantime I think this will work:

insert and card into computer, should show a disk called “boot”

or, if someone can take a clean image, update it, and post it somewhere in the meantime.

download and unzip the update manually on GitHub

copy contents of kernel/boot and kernel/shield folders from update to SD card

hopefully the wifi works and you can run the update for real after

Just to double check, so does it means that the shield works with Crow? I might have a target for my first salary…

I’ll make a ponoko/razorlab friendly version of the design and post it later.

EDIT - Well poo… the ponoko “P1” layout is like 4mm too small for the design.

EDIT 2: here’s a Ponoko P2 layout with 4 copies of the shield case (added in/out legend above the jacks): norns-shield_case4.eps (6.4 MB)
(3mm / 0.118inch material thickness)

Just put my shield together, very excited to try it out!

I’m using a Raspberry Pi 3B+, flashing on a Windows machine using https://www.balena.io/etcher/

At the moment, however, using norns200106-shield.img.zip is resulting in a rainbow screen. Brief flicker of green LED, then just a solid red LED.

I’ve installed Raspbian using the same card and the same Raspberry Pi (as well as two other Raspberry Pi 3s) and it boots as expected. I know that my power supply is sufficient.

If anyone had suggestions I would be extremely grateful!

norns image disables the HDMI so this is normal.

are you getting anything on the OLED?

#242

Good to know, thank you! I am not getting anything on the OLED.

It is unfortunately very possible something is wrong with my soldering - I am very inexperienced at it.

I have flashed a brand new SD card (as in, from the package) using my Mac (instead of my Windows machine) with norns200106-shield.img and the Raspberry Pi’s LEDs behave differently - green flickers on an infrequent-but-regular basis instead of an initial flicker followed by nothing.

This seems like a positive sign to me, but I will have to wait until I return home to try it with my Norns shield.
