Nikon D3400 with no external mic jack? Idea on how to get it? Is my idea viable?

so elgado released the camlink that allows you to connect your camera to a pc to use as a webcam and also works with obs studio as a webcam so I was thinking of pluging in my windows tablet with usb 3.0(Recommended on site) to my nikon d3400 with the cam link and then mounting the tablet to the camera with multiple adapters including a hotshoe spliter(for the mic) and then pluggin in my microphone to the tablet and mounting it on the hotshoe, it is about $200 in parts and it gives me a sweet 1080p monitor, it gives me external audio, and it lets me tweek the mic imput and everything while shooting but the only down fall i see is that the camera will turn off in 30 minutes(which is still better than the 20 minute recording limit) and it also lets me shoot in 1080p at 30fps, 60fps, or 24 fps.
my camera is compatible with the requirement and so is the tablet, so i was wondering if this is an ok idea, but i was also thinking of at somepoint upgrading to a 4k camera like the panasonic g85 or the sony a6300.
Imput would be apresiated on if it will work, i think it is a god idea cause i can also use it with future cameras but it is a kinda bigger investment.

Nikkor lens problem (manual focus is stuck)?

I have a 18-55 F3.5-5.6G Ed II AF-S DX Nikkor Zoom Lens, and a few months back it fell off a table and landed right on the edge of the lens. (luckily I had a UV filter on it so it just chipped the edge of it). Recently the manual zoom is stuck. The auto-zoom works just fine but when I switch it over to the manual focus nothing happens. It is acting like it is not switching over. Can this be fixed? Or do I need to send it in for repairs? I probably won't send it in because it is not the best of lenses and I hardly use it. Probably costs the same to repair it than getting a new one.
Added (1). "Auto focus" not auto zoom.

How to use Vivitar auto thyristor 283?

I have a Vivitar auto thyristor 283 and I put batteries in it but I'm completely clueless and new to flashes. I have a nikon film and a kodak digital will it work with these? It was given to me so I don't have a manual and I have no idea how to use it. And I have no idea what the dial on the side of the flash is telling me or how to set the sensor. Any help would be greatly appreciated!
