Given that drone warfare is now a thing this seems like it could be useful as the basis of a personal drone detection and warning kit that soldiers could wear over their helmet to spot drones and give say an audible warning in the soldiers ears that lets the soldier locate the drone direction and maybe azimuth with pitch - lower frequency for a low drone and high for one more overhead. Not sure if such a thing alread…

Shotguns have proven ineffective as drone defenses. Range is too short and the targets are too fast.

Watching football this fall, I've been thinking about a little box that sits on my table and mutes the TV whenever an ad comes on. Not decoding HDMI HDCP or anything, but a webcam + AI or whatever that watches football with me and mutes ads. Similar to plane detection, maybe. Are there any projects like this?

how about fingerprinting? Not versed in this space but might be worth looking into.

I'd settle for a device that just normalized the volume levels, but this would be even better!

Here’s a DIY project to make a TV volume limiter, I haven’t done it myself but it looks cool: https://www.youtube.com/watch?v=j1V2I-otdzk

Nvidia shield can do that, they call it "nighttime listening mode" or something, I leave it on permanently, much better experience.

Nice idea! Related: In Black Mirror, they pause the advertisement when you disable the sound. So maybe you'll eventually have to use a separate sound system whereby they cannot detect that you're muting it. Then, they'll track your eyes and require you to watch the screen :) At which point do you stop consuming?

Drink a verification can to continue.

Check out the recent controversy over Activision and Call of Duty. Evidently the game code requires access to your webcam and the company has patents on using your gameplay to train a bot that play like you do, then uses the idle time to make the bot play while you are away. This bulks up the pool of players ensuring you are matched with people resulting in a good experience for you. There's also a patent detecting your emotional state while you view their in game store, possibly for adjusting price to influence you to buy or spend more.

This is great. So I’ve thought of doing something slightly similar but with a raspberry Pi and camera to identify if there is a free parking space right outside our house (we live in a terraced house with no driveway)

I think this has been done for public places. A lazy approach (not using ML) is cropping/contour finding, then masking (opencv) against an empty parking lot, so if something is there like a car, would change the result. The black parking lot would change in shade/hue so have to account for a range.

Thanks for the reply. Yeh I’m sure something like this exists. I could probably just mask out the area around the space o lab the streets outside our house and then send a notification when it becomes available.

The complexity maybe comes in in identifying our cars parked there vs someone else’s, so maybe I need number plate recognition. However my camera would be top down so likely no number plate would be visible.

Any thoughts/recommendations are helpful

Looking at the electric consumption of my 30 closest neighbors using an RTL-SDR, I'm still wondering what I should do with the information.

They are better than other guns though.
