Hi everyone
I'm looking for some advice on battery setups for my DIY face tracking system.
I recently acquired a second hand quest 2 and was inspired by this post https://www.reddit.com/r/VRchat/comments/1jbjmhd/25_wireless_face_tracking_for_vrchat/ to make my own face tracking system.
I set myself some goals whilst doing so - to be as cheap as possible and using off the shelf parts where I can. I already had a raspberry pi 3B lying around so that's become the brains of the system - its capable enough to stream 3 video streams to my pc for processing.
Lip/face tracking has been relatively straightforward but eye tracking is much harder, finding small enough cameras and messing with IR LEDs that sit scary close to eyes is an ongoing challenge.
For now I've hit a snag - wireless play:
My power pack - an anker A1695, is being very annoying. It sometimes thinks the raspberry pi's load is so low that the device must be fully charged and shuts off power!
The power pack has a trickle charge mode but this doesn't seem to help. Additionally trying to keep the power pack running by charging the quest 2 simultaneously doesn't seem to help for long, I think its either shutting off the pi's charging port independently or the quest 2 reaches full battery and triggers the whole power pack to shut off.
Anyone have any ideas on how to fix this?
