Yeah, I loved the form factor, it was the software and the cloud dependency that crippled it. I've actually been looking at a Vufine+ combined with an Intel Compute Stick to create a more customized alternative.
The Vufine+'s battery life kills that option for me. Wearables need to have a long enough battery life that you can use them most of your day without taking them in and out.
Definitely true. My impression is that I'd use it cabled with a battery pack (that could also power the Compute Stick), but since I already need micro-HDMI running off of it, that's two separate cables.
I've mentioned this idea to the Vufine team, but if they removed the battery (to lighten up the unit significantly), and switched the cable type to a USB-C that delivered both video and power, it could reasonably offload battery to an external pack, and run video along the same cable, and I'd maybe clip something on my belt and be rocking.
That being said, Vufine's current hardware isn't designed to be a day-use wearable, it's intended to be used for things like seeing the camera on a drone you're flying (which also has a very short battery life).
I'm not sure that the USB-C cable buys your much that some electrical tape couldn't provide. Besides usb-c being a more elegant solution.
Offloading the battery would be helpful for longer sessions. I wonder if you could either completely remove it and use pass through power or replace it with a smaller/lighter battery.
