Were you able to complete this ring? #1

Hi @Cosmopal , no unfortunately I was not able to actually implement it. The complexity, as far I remember, was:
So if you wish to try to actually build it or can somehow help with the issues - that could be a great kick for me to continue the hw & firmware development. For now it's not really needed by anyone - so I stopped development since have some pressing projects. As far I see I can copy the antenna design of the ring I used as prototype or try to get OmniRing design: https://www.cse.psu.edu/~mkg31/projects/omniring/ , but not quite sure if that will fit... The battery for sure can be used from another cheap smart ring, but about the vibration device I'm still not sure. |
I think building the ring incrementally will be more practical. We can start small and at least have a working prototype on which we can build up. It's a challenging project for me too, which is why my idea of a first version was very small - basically a counting ring that keeps the count of number of times you touched its touch sensor, and is able to transmit that info. We can modify your current design to include a touch sensor instead of the vibration motor. Can you share some details about the three challenges you mentioned above? Let me take a stab at it.
The OmniRing's paper is there, but the design, specs or program is not available. One has to fill a Google form to request info. I did try to reach out to OmniRing team, but they have not been responding. A ring is a very potent wearable device, and I'd love to have a tinkerable open source ring. |
I think it's reasonable to build it incrementally - for sure you can remove some unnecessary parts (just do not fill the places there on the PCB). There is a physical button included in the design, because I found that touch button is not work that great - but if you need you can modify it to touch for sure. "Replace the BT sensor with NFC" - what do you mean? Not quite sure I understand how nfc will work as a charger and what is "BT sensor". And what kind of additional info I can provide? Not sure if you looked into the repo - there are 3d models, PCB and sample firmware (just the beginning of it), so it contains everything I have for now. And I recalled that I managed to replace the pcb antenna with solid state one, so one problem less! |
Yes, I found the docs you had put in the repo. I’m still going through them. I was looking for details like:

Hi there! Just found this while looking up OS ring designs. A couple of thoughts in case they are helpful:

hi guys. this is the battery that oura ring uses: 3.7V 16mAh Lithium Battery - Grepow YE160723G. its custom curved lipo. would love to connect further |
Hey,
The project looks very promising, I would love to colab and get this to completion.
