projectnorthstar's Issues

missing Gerber files for electronics production

I noticed that the electronics folder includes a BOM and schematics, but the Gerber files are not available. Are there plans to make these files available?

Also, will we be able to purchase the custom components like the reflectors and the infrared LED/camera array directly from Leap Motion?

Thank you!

Could the hardware of the current release been used in the next 4 versions?

WindowOffsetManager Error

Please Advise on the following error:

Assets/LeapMotion/North Star/Scripts/WindowOffsetManager.cs(55,16): error CS0117: UnityEngine.Screen' does not contain a definition for fullScreenMode'

GPL Licensing Issues

I noticed this project recently changed it license to the GPLv3. IANAL, but there appear to be some issues with this which would affect anyone attempting to use this code in a GPL-compatible project of their own.

1. Unity is not GPL compatible
2. Leap Motion Unity Modules are not GPL compatible under the Leap Motion developer SDK agreement.
3. Numerous files within the package begin with a header mentioning that they are distributed under the Leap Motion developer SDK agreement which forbids redistribution (a requirement of the GPL).

While I find it admirable to want to use a free software license like the GPL, it does not seem to be a viable licensing choice for this project. My understanding is that this code base is also incompatible with the previous Apache 2.0 license as it also requires redistribution rights to be granted.

If you really do want to distribute this publicly its likely that the only licenses compatible with your dependencies are MIT or similar "open source" licenses which allow you to re-license your code under the proprietary Unity or Leap Motion licenses when distributing derived works including them.

Missing STLs for 3.1 update

Missing 131-001 and 131-002

Missing STL for v3.1 Release

Hi guys,

Great project. We're trying to print the mechanicals here at DoES Liverpool. I can't find this from v3.1 BOM. Can somebody point me in the right direction please? [Edit: i.e. can't spot it in the 3D files zip]

#110-005 | 1 | LEFT SLIDE ENDCAP - 3DPRINT

does not work with unity 2020 or newer . seems to have bunch of code that understands at least as far s 2017_2

STL mislabled

https://github.com/leapmotion/ProjectNorthStar/blob/master/Mechanical/North%20Star%20Release%203%203D%20Files/3D%20Printing%20STL.zip
File "#110-003" should be #110-002 according to BOM

Source for ANX7530 and 1400X1600 MIPI Oled Display

Is there any known distributor source for the Analogix ANX7530 chip? I know it is being used in the Vive Pro, Magic Leap One, Pimax 8K etc...

Would the the Samsung AMS350MU04 AMOLED panels used in the Vive Pro and the Samsung Odyssey be considered good substitutes for the BOE displays?

Can I use Usb stereo camera made by other manufacturers?

Can I use Usb stereo camera of other brands or manufacturers for calibration? do I need to modify the dualStereoChessboardCalibration.py file in order to calibrate normally?

#310-003 FDMI OPTIMIZED.stl is not FDMI optimized

In 3D Prints.zip the part numbered #310-003 FDMI OPTIMIZED.stl is not FDMI optimized like the other ones marked optimized are.

Two STL files contain too much

Inside the file Mechanical/North Star 3D Files/3D Prints.zip the files cheek guard - left.stl and optics bracket.stl are identical. Both files contain the optics bracket and cheek guards combined. Looking at the file names I suspect they should contain the respective part only.

dualStereoChessboardCalibration.py - cameras not populating calibration screen"

Hey my python environment variables are set, but the issue that I am running into is that the expected 4 windows are not populating. Any ideas?

python dualStereoChessboardCalibration.py
No Calibration file found...

Above is the output and No calibration screen.

Thank you,

Does anyone sell the Display Board?

Hi, I am trying to make the North Star but I am stuck with creating the board - 0.1mm drills
Maybe someone has a spare board, otherwise can link me to the right manufacturer that can print this board?

Thanks

A namespace error by TextureCompressionQuality

Please fix the namespace on line 343 on LeapMotion/Modules/GraphicRenderer/Scripts/Utility/AtlasBuilder.cs

Assembly instructions are on a separated website

It would be helpful to have every resources to assemble the hardware as part of the Git repository.

I know this page isn't complete, but translating this into Markdown and putting it inside this repo, with a link from the README would be nice https://leapmotion.github.io/ProjectNorthStar/mechanical.html

Missing parts

1 - Hinges look different between the 3D print files and the instructions here: https://leapmotion.github.io/ProjectNorthStar/mechanical.html

2 - Slide Endcaps are missing from 3d Print files

3 - Two little pieces that screw onto the Optics Bracket (next to the fasten display) are also missing from 3d Print files and instructions

Electronics pcbs and B.O.M

Hello.

I have been trying to get the PCBs for the projects. Through a Fab lab I can see the BOM and the other
folders like the Display drivers folder and gerber. But its no clear what is what. On the guide the electronics part says coming soon

https://leapmotion.github.io/ProjectNorthStar/

Has anyone got helpful information?

Kind regards.

Unreal support ?

Can we get Unreal support as well ?

Not working on Shader Graph or Visual Effect Graph rendering

LeapAR.unitypackage has problem I think.
Shader Graph or Visual Effect Graph needs settings of render pipeline.
When I change the graphics setting bellow. It's not working.

If we could have these, we can make SUPER COOL EFFECTS by the way!

Shader Graph

Visual Effect Graph

BOM in proprietary Microsoft Excel format instead of a standard, open one

The BOM for electronics has been pushed in a non-open format. It would be nicer to have this file as an open document (.ods) file.

Lenses

For now can we get the manufacturer you used to get the lenses made regardless of the cost?

Printing 120-002

Is there anyone that could help me with that model? As you know, it's really weird and I have 0 ideas on how to place it, so I can print it nicely. I've tried just laying it, but that will most definitely not work or I mean it didn't work. So any tips?

Connection Problem

Hi, I am trying to test this project in my Mac OSX, but once
it is connected and all installed, I cannot see anything in the Gameview or in the glasses.
What's more, this error appears in the log:
DllNotFoundException: LeapC
LeapInternal.Connection.Start (LeapInternal.LEAP_CONNECTION_CONFIG config) (at Assets/Plugins/LeapMotion/Core/Plugins/LeapCSharp/Connection.cs:161)

Leap.Controller..ctor (System.Boolean supportsMultipleDevices) (at Assets/Plugins/LeapMotion/Core/Plugins/LeapCSharp/Controller.cs:365

May you be able to tell me how to solve it? I am using Unity 2018.4 LTS.
Best regards,
Andres

Is there a solution to this problem?

[Tips] 3D printing the headset frame

Hi guys!

So, I suppose a lot of people are going to throw the files on these repository into a number of different desktop FDM 3D printers.

I would be curious to see what configurations and settings we are using. I've been attempting to printing the "FDM Optimized" Optics bracket since yesterday.

I finally resulted into throwing the file into MeshMixer and adding a bunch of support around the frame that should hold the reflectors.

I'm currently printing this on RED Prima Value PLA with the following settings on a Dagoma Discovery 200 3D printer (little machine made by a french startup a few years ago. Dirt cheap but not really reliable I'm affraid 😅 ) :

• Temp 210°C
• 0.2mm layer height
• Raft on
• Supports off (added by hand in meshmixer
• Infill 100% (it's not that much plastic anyway)
• printing speed 80mm/sec

I've made several attempts at printing this between yesterday and this afternoon, but this one looks promising.

If it 3D prints nicely, I'll share the modified STL in a pull request 😉
