Hi ! Please, Is it possible to use a powered USB hub for to have more USB ports for Norns ?

#451

yes ! as long as every device gets enough power u can have as many as you want to my understanding

If you are looking for a hub that allows you to stay battery powered I can strongly recommend this UGREEN USB 3.0 Hub 4 Port Ultra Slim Data Hub with 5V Micro USB Power which can optionally be powered with another USB power source. I routinely use this combined with a USB battery pack with one cable to norns, the other to that hub.

Hello,

Iā€™m thinking about getting Norns, and it looks like lots of fun in the field, but when Iā€™m back at home/studio Iā€™d love to have Norns in a 19" rack to integrate with my other studio gear (mostly just to keep things neat). Iā€™m pretty handy and can build something but Iā€™m wondering if anyone knows of a 19" rack kit that works well with Norns?

Thanks,

Tom

Mount it on a rack slide out drawer?

Norns is a little box, why mount it on a rack?

I have mine hooked up to my patchbay in my rack, but i donā€™t otherwise have it mounted ā€œtoā€ the rack in any way. The interface of the norns is entirely on its top, so in a rack mount itā€™d take probably 3U of height (if you use right-angle 1/4" cables, 4U otherwise), but only an inch or so of depth. A slide-out shelf or drawer would make sense though!

Can i use more than one usb powered midi to cv devices and make actual use of lets say 2 of such giving me 3 pairs of cv/gate?

I suppose while it will be recognized by norns i am not sure if scripts could make use of it, any examples? Thanks

Anyone powered pedals from one of Norns USB jacks? Iā€™ve seen a few USB to 9v cables, but Iā€™m not sure if they are reliable or safe. Does anyone have recs?

#463

i have used such a thing to power low-current stuff like fuzz / gain - like 20mA, an order of magnitude less than a hungry DSP pedal. but even a hungry device should be fine, just be aware of the total draw of all connected devices and best keep it under 1A or so.

the issues iā€™ve had with that setup are more about noise. the 5v can be a little gunky and carry some bleed from clocks, etc, so may be problematic for powering a gain circuit depending on your tolerance. (no different from most laptop USB jacks in this respect - e.g. i just experienced dealbreaking noise coming outta a moog when it was also acting as a USB midi controller.)

havenā€™t compared different brands, the thing i have is cheap and generic, maybe there are fancier solutions that perform better power filtering.

i havenā€™t already received my norns (coming in a couple of days) and I am already making a midi controller for it! Guess I will add a midi din port and a power switch later

Did you ever find a foot pedal that works with norns ?

#467

looks great.
iā€™m always looking for good controllers but have not really tried to DIY one yet (other than a few foot pedals w/ mixed results)

Iā€™ve built a usb-midi controller based on the atmega32u4 and Prost usb midi host to host adapter. Happy to share code is people are interested.

Exactly is a mega 2560 clone from elegoo
Iā€™m still soldering, but I guess iā€™ll totally copy the code from the notes and volts tutorials on youtube
