I don't think that's a novelette. If there were five chapters all approximately the same length as chapter 1, I think it would qualify as a full-on novel. If you would finish it, you could always try Kindle Direct Publishing. Same with Torn. But if you do a board game or book, I think you should change the name from DigiChars since that came from being virtual computer stuff.
As for the Cup Clamp, I think you could apply to be on Everyday Edisons or Shark Tank. They are truly interested in getting things to market, as long as they believe the idea is good. Plus you might get to be on TV. Or, just watch those shows for some idea of what you could do with it.
OK, enough of that. Time for me to humble myself, as well.
First of all, you've taken all of those projects much farther than many things I have thought about. Things like...
A noise generator
I like to play with sound. One thing that really interests me is "black noise". What's that, you say? Well you know what white noise is. All of the sound frequencies together, making that KSSSHHHHHHHHHHH sound you get when you turn on channel 74 without cable. Black noise is indeed the opposite. It turns off all sound. That is, it's the reverse of the input waveform. You can find a cheap and not too effective version in those noise-cancelling headphones.
Here's the sound you're hearing:

If you flip the waveform:

And play it back:

They cancel each other out. Of course, you have to match the volume of the source frequency. And if you want to silence it, you have to do this all instantly. I know there is a way to do this with a microphone and the right electronic circuitry. Something about a XOR gate or something. I just don't know what that way is.
This is common theme you'll find in my idea graveyard, a lack of sufficient knowledge to implement. I know theory but not much practice, and I am ashamed. I wish I had understood things better when I was young so I could take my education in a different direction.
I got as far as a mockup. A friend who knows more was going to help, but he was mired in his own poor motivation. When it became apparent he was abusing his girlfriend, he had to leave the house.
BUT I DIGRESS. The thing should have been about the size of a computer keyboard, probably somewhat thicker and deeper. It would have standard 1/4" and RCA inputs and outputs (BYO amplification). And while black noise would be the predominant feature for me, I wanted it to also be capable of generating white noise, as well as pink, blue, and other types of noise. And have a delay feature for the sound canceling (interesting effects from offsetting the reversal) And, if there's time, frequencies ranging across the full range of human hearing and beyond.
I've had at least two more ideas using electronics to create/translate sound in weird ways.
Comic books
That's what I wanted to do when I was a kid. Make comic books. I did come up with a team of heroes. The main guy was basically a Ninja Turtles ripoff named "Ace" and the main bad guy was pretty much Shredder, except he was a tiger. The good guys team was four members, but in a terrible attempt to be original they were not turtles. There was a little puffball kind of thing with wings who could transform into a much bigger and tougher creature. I don't even remember who the others were. I did a story that made it about five pages before being abandoned. It was pretty pathetic, although I'm not sure if I realized it at the time.
Slightly better, but never getting more than two pages, was a character called "Mantis". He escaped from the insane asylum during a thunder storm. He wore a trench coat, a giant grin at all times, and the 90s-est haircut ever, and had two knives with giant blades. The kind with brass knuckle/spikes on the handle guard. Like Batman, he refused to use guns. The bad guy was "Kwiksotik" (Quixotic, and his backstory was something about he believed he was doing good. Maybe kind of like Punisher but not as violent and with a more cartoonish costume) and he did use guns; I didn't realize at the time but looking back, he also kind of looked like a Batman villain (circa B:TAS)
I don't have any of those pages I drew. I think I'm glad about that.
