Last time I ordered, Oshpark had free shipping to EU :wink:
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?

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.

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.

Offworld-2: USB power utility
Grid ops / integration
#49

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?

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

@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?

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?

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.

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.

noise problems-- be sure you’re not dealing with physical noise in your grid-- a batch of 100 back in 2015 got built with ceramic caps on the power lines which make a physical sound coming from the grid.

Tried this and it didn’t work for me :confused: if i plug the grid right into a phone charger, it seems to get power (does the little animation when its plugged in) but it doesn’t seem to be getting anything when i run it through the splitter. (I’ve made sure i’m using the side with the red wire still intact.) The splitter in your picture of cutting the wire looks like it is different from the ebay picture you linked though… it’s a bummer because the noise I’m getting is significant and I really don’t want to spend 24 dollars on the offworld just to fix this :frowning:

upon closer inspection…the splitter I ordered doesn’t seem to have data wires, just red and black which I assume are power and ground. that being said…shouldn’t grid still be at least getting power from the side with the wires intact? very confused

hmmm, that’s strange. The one I purchased explicitly mentioned “Both splitter USB Male can charge, but only one usb male can data transfer”. I tried both ends to see which one had the data cable and cut the red power wire in it. Perhaps you got a defective one?
