Ansible & grid / power issues?

[stripes]

i have an ext5v and it doesn’t remove any noise when grid is connected. would cutting the red wire in my usb cable going to ansible from the ext5v effectively do what was posted above and get rid of the noise? also going to get some ground lifts today and see if that does the trick.

[tehn]

the red wire in the usb cable isn’t connected to anything-- the ext5v’s purpose is to leave it unconnected and get power from the supply instead.

yes, try a ground lift on your modular’s power supply. what power supply are you using?

as a recap
1 - find a Y splitter DATA-POWER
2 - cut the red wire
3 - enjoy

???right???

if is that simple you are my solution to the 1010bitbox maxing power problem!!!

i’ll try

thanks so much guy!!!
best forum ever!!!

here’s a better solution-- power to 2 devices.

Offworld-2: USB power utility

open-source PCB: https://oshpark.com/shared_projects/b4LjJ3lk p/n offworld-2 for $3/ea powers two USB devices (ie, an arc and a grid) with data passthrough to computers/modules/etc. power provided by a mini-USB port, which can be connected to a common USB power source (two-prong apple thing, etc). this version is different than the SWITCH module, which powered one device and toggled the data pins between two ports. requires only two part numbers (with Digikey links): qty 2: UE27AC54100-ND (…

Thanks Brian…problem is US shipping…
in europe i think is more manageable to get something like this

DeLOCK 83176 0.3m USB A USB A Maschio Femmina cavo USB: Amazon.it: Informatica

Last time I ordered, Oshpark had free shipping to EU
edit: you end up with 3 boards, other people here might be interested in one too though

Could someone who already uses one of these offworld pcb things maybe post a photo of it in real life?

As a non diy-person, I have problems understanding what it even is.

Agreed

Anybody built one?

[ghost]

I’ve ordered some boards though they’ve not arrived yet. I understand it to essentially be like a 2 channel ext5v: 2 x in and out port pairs (one for grid, one for arc) and one port to connect to power.

[tehn]

i just created a new version of the offworld which is much smaller, for a single device.

i’m making a matching plexi “sandwich” to cover the bottom and top so it’s more mechanically robust and without exposed contacts for shorting.

i’ll get the files posted soon, but i’m finally going to offer these as a DIY kit (all parts included) and prebuilt.

i’m sorry it’s taken so long-- i finally found a really nice USB-A that’s mid-mount so the whole thing is slim and finally elegant.

I’m having a strange experience with a usb splitter that @ado has had luck with.

I picked up the same one he posted about from eBay. When I plug my grid or arc into ansible with one of the two leads from the splitter I get normal operation. When I plug in with the other lead I get a brief flash of the leds and then nothing.

I tested the splitter with my phone and both leads charge the phone normally.

Any thoughts?

[boboter]

Thanks for posting the pic. This is a really nice solution. Definitely getting a pre-built one, when they are ready to order.

[ado]

@jasper_ryder that’s correct, only one of the leads has data wire. You want to cut the power wire on the lead that contains the data wire. The other power only lead will be connected to 5V power source.

Tred following through on links yet curious to exactly what this does? Is it something similar to the ext5v?

[unity2k]

My Teletype has just shipped today so I’m still a short time away from placing my order for a Grid.

If someone could help me understand; it is clear that the TT cannot provide power to the Grid so another solution is required. I get that the Switch is gone for good but that Offworld will fill its place.

In @tehn’s image above it suggests that I could power the Arc and Grid simultaneously, I’m guessing that the main USB connection (not the ones going to Arc and Grid) is going to some kind of USB hub or a port on a computer that can supply enough current. Correct?

If the Arc and Grid are plugged into the Offworld how do they simultaneously plug into Teletype and Ansible, are they using a Y splitting cable somewhere in the path?

It seems that Offworld might be a source of noise with some people’s setup, did the Switch suffer from the same problem?

I’m thinking about ordering an assembled Offworld when they become available as they appear to be a rarity but an essential item if one wants to explore the Teletype talking with the Grid. Is there a mailing list or will the availability of Offworld be announced here on Lines?

[jasper_ryder]

Read post 29-32 in this thread. There is a $3 usb splitter solution. It works fine. Sounds like tehn will be releasing a nice smaller version of this shortly.

[tehn]

@unity2k ok, offworld is now availalbe direct from us. i can combine your order if you want since today is a postal holiday and things won’t get dropped off until tomorrow

Awesome. Done. And more awesome for 20 characters.

[monolithicfungus]

Thanks for making that available through Monome, Brian.

Anyone here using Ansible/Grid with a Make Noise powered skiff? Wondering if that case has the juice to power Grid without the high pitched noise.

Was thinking about picking up one of these anyway, and would be happy to make it Ansible’s home. Otherwise, Offworld here I come.

I am, and no: the high-pitched noise is very noticeable. Hoping (and expecting) that using an Offworld-1 will sort it out.
