Metro Smart Watch

I had an idea the other day whilst playing Metro: 2033, I imagined a smart watch made like Artyoms watch but instead of having an LED come on when you're visible, having an LED linked to your phone that comes on when you have a message like an external notification light and wondered if there's any way to make this a reality?

Building Touch Sensors from Scratch?

I am very familiar with velostat and conductive fabric and how to combine them to make textile touch sensors. I would now like to make a touch sensor that's more solid, and made from a firmer resistive substance than velostat. I've been looking up the resistivity/conductivity of different metals here: https://www.thoughtco.com/table-of-electrical-resi.... In theory, as long as one metal (or other material) is more conductive than the other, it should work the same? I've read on silicon and carbon fiber, but I'm not sure if what I'm researching is the solid kind, or the flimsy/squishy/bendy kind.

Setup Cable Management. Convert to Wireless.

A while ago, I dropped my laptop and shattered the screen. Because it was less expensive to just buy an external monitor, I removed the entire upper half of my laptop and am using the external monitor. The problem is that this leads to a really clunky setup since I have to connect all of my wires to the laptop base which I'm using as a keyboard. My idea is to instead connect all of the cables to a hub I'd build into my desk, and that hub would transmit the signal wirelessly to wireless converter dongles in my laptop's USB ports. Any ideas on how to make this work? Is it even possible? I couldn't find any female Bluetooth adapters. Any advice would be appreciated
