I don’t know off the top of my head but I’d be surprised if macOS runs a DCHP server unless it is setup to “share its internet connection”. If you can’t get it to work I can do some experimentation later today.

UPDATE:

@fac_6 - I just tested out a direct ethernet connection with my MacBook Pro (a late 2016 touchbar model). If I open up System Preferences and select Sharing, Enable “Internet Sharing” (on the right) then select the network interface with norns attached on the left (which in my case is a USB-C gigabit ethernet adaptor) - then everything works.

…once sharing was turned on I could use norns.local in a browser to get to maiden and connect to it with ssh, sftp, etc. in a terminal. As a bonus if your laptop is connected via WiFi to another network with internet access norns will have access to the internet as well. In my case norns was given an IP address in the 192.168.2.* range once internet sharing was turned on.

Norns wifi issue

Thank you! I will try it out today.

Bit late to the party here. Just updating to 2.0.

As USB has never worked for me (still doesnt :frowning:) I have dropped the 190405.tgz (original file) into the /updates folder via SFTP & cyberduck. When I go to UPDATE i get ‘no updates found’

Am I missing something? cheers for any help!

#1357

your answer should be in here (seems like you might need to install via serial connection): Norns 2.0.0

cheers…apologies for being an idiot. it’s a while since Ive updated. In terminal, how do I auto fill the serial number of the USB. at what point do I hit TAB? for me it just gives me an error sound.

#1359

first, be sure your norns power port (usb mini) is connected to your laptop.

open a terminal, type:

screen /dev/tty.usb

then press tab.

is you get a bell, please tell us what OS and version you’re using (as this means your FTDI driver isn’t working)

Picked up my FM7 project with new developments. Been working exclusively on it for a couple days. I’ve added the following devices to the USB port

  1. Arc
  2. Grid
  3. USB MIDI adapter
  4. Wifi nubbin

I’m using the ~ 2 amp power adapter and the device has been on for more than 24 hours. While not a problem, I’ve noticed the battery level very slowly dropping. It’s been plugged into AC current this whole time but now the battery is ~ 88%.

Could this be caused by all four devices needing > 2 amps of current? I have left both Arc and Grid LEDs illuminated for hours at a time while coding.

#1361

this is expected given the power system arrangement. there really is a cap to how much power can be pulled from the USB system— having four ports certainly allows for over-drawing, but i wanted to include four because many devices use almost no current.

here are my suggestions:

  • design grid/arc LED interactions that are not overly bright, as current consumption is directly proportional to overall brightness
  • limit CPU use for your engine. the CPU alone when loaded can consume a lot of current
  • if neither of these are options, i’d suggest using a small externally powered USB hub, which i know is not elegant, but sadly there are limits to this system design and this was a compromise i judged as a reasonable tradeoff

Perhaps an offworld or two?

#1363

Cheers for the help, terminal worked but update didn’t.
got NONE (error : AUDIO ENGINE) on menu page with parameters etc

Just in case its relevant im on Mac OS Mojave 10.14.3.
I have uploaded the update to Norns via SFTP and also tried all available inputs with 2 different FAT 32 USB sticks.
Norms seems to be connected via my network at times then says password fail at others. So then I tried hotspot. this connects but doesn’t really get me further.
via cyberduck I can see the update (190405.tgz) is in both the /update and /dust/usb0 folders.

#1364

just to add. in further attempts terminal gives me ‘could not find a PTY’ after saying something is busy… so quick I cant see what it says.
The USB stick is recognised as when its not connected and I go to sync I get no USB found. when connected I can see the three options.

Also tried (in terminal)

sudo cp /media/usb0/*.tgz ~/update/

but says update does not exist.
In maiden im getting:
ls: cannot access ‘/home/we/update/norns*.tgz’
: No such file or directory

#1365

prior to sudo cp ... do

mkdir /home/we/update

what you actually need to do is this: Norns: update fail recovery

I’ve noticed that its also higly depends on mini usb cable, used for charging. Just tested 3 different cables (lost original one, unfortunately) and only one gave 300mA, while with others it kept discharging

#1367

the included cable we shipped is high quality (molex) with thick conductors, and the power supply provides 5.25V (instead of 5V) which means high current draw will not brownout the supply (voltage drop due to resistance of the cable).

so, running norns with a thin cable off of a low-current/low-voltage supply (ie, an old old USB port that limits to 500ma) will not be optimal.

#1368

What is the best way to increase the overal longevity of the Norns battery? Can I just leave it powered all the time? Should I “cycle” it by letting it run down and then charging fully?

#1369

i don’t have any battery life suggestions but it’s a standard lipo so you can google.

also it’s the same model as this: https://www.adafruit.com/product/2011

so you can get a replacement whenever.

Can we put a bigger one like the 4400 mah?

#1371

if you can make it fit, yes, but that is very unlikely

#1372

I was having issues with mlr this morning; I tried resetting multiple times to no avail so I tried deleting and reinstalling the script, but now I’m just getting an error message that says error:init. Has anyone seen this before? Any ideas on how to fix it?

#1373

connect with maiden and you will see the full error message, paste it here and I can help!
