Uhh... this is about as innovative as a much cheaper DIY project from many years ago? I think everyone with a vufine and a pi zero has done this before. As a bonus you get to use linux instead of android.
Maybe the only thing I sort of had to hack together was the stupid mount for the vufine which is a bit cheap and flimsy. This is a necessary mod anyway if you buy one of these and want to use it for anything serious. I dremeled out a channel on the magnetic mount and ran a velcro zip tie through that. Holds onto a pair of glasses very firmly now. I added a second velcro strap around the body of it for stability. I can even go out for a jog no problems. All the cables I use are thin and lightweight (meant for connecting HDMI on a drone).
It's such a cheap and obvious idea that you can unregretfully drunk buy all the parts on amazon right now for probably less than I paid back then and you'd still just have a pile of otherwise useful stuff. The hunt for durable low-profile and L-angled cables needed to cram it all into a pocket is the expensive part, but you might even already have a pile of those.
Where did I say it doesn't? You seemed to be complaining about the fact that it was not innovative. I just said that innovation often doesn't matter. A good product works well, doesn't have to be innovative. Innovation is mostly great for marketing and VCs.
