He uses an image segmentation model to detect if a person is standing under his apartment.
Computer vision _was_ a legit AI field until "only LLMs are AI now" came around, no?
You have it reversed, no? Computer vision was just called computer vision and computer graphics until "AI" became the new headline grabber, then computer vision somehow became "AI". Even optical flow from 30 years ago is now being called "AI" by some people even though it has been around for decades and doesn't work off of any training, it just tracks every pixel to get motion vectors.
Ah fair enough, good points on further consideration =)

This concept is great, it’s also a brilliant idea for a webcam on a Bourbon St balcony in New Orleans to throw beads at parties below. I am friends with a guy who owns a multistory bar in the middle of the strip and would be open to this, so if OP or someone else is interested in developing an AI/remote control bead thrower, drop some contact info and I’ll reach out
I live in Louisiana, have done object recognition projects before, feel free to reach out. Email in bio.
I live in New Orleans. Happy to help as well. contact in bio.
AI to recognize a pair of titties and then trigger the beads. Genius.
I will be honest, while the project is actually neat, it showcases some of the issues with technological advancements as related to society ( and happens to also touch on one's exposure in a big city ). One could easily imagine a scenario ( or scenarios ), where this could be misused.
Right? I can already imagine the government doing this to drop nuclear bombs on dissidents.
You seem to be making it unnecessarily dramatic for comedic effect and it does not have be government in attempt to dismiss genuine concern. The only reason I am not expanding on it is because I do not want to give people ideas.
Perhaps it can be used to drop water balloons full of Gatorade on parched travellers. Or, to extend the earlier concept, miniaturised atom bombs on beatniks.
As the saying goes, "ideas are cheap, execution is everything".

I guarantee you that you haven't come up with any ideas in the few minutes you've been thinking as a casual and presumably non-criminal observer that haven't been thought of already by countless criminal and terrorist groups. The only thing you're accomplishing by being vague is making it hard for us to understand what you're getting at.

People are influenced by what they read.

Whether the idea has occurred to a bad actor and if they choose to act on it are very different.

We effectively “promote” bad ideas with detailed public discussion; it’s literally what influencers get paid to do.

Hmm. On this very forum you will often see me argue actions vs speech and how the two are very different from one another and how only one of those can actually be construed as violence.

<< I guarantee you that you haven't come up with any ideas [...]that haven't been thought of already by countless criminal and terrorist groups.

It is likely. My imagination is somewhat limited, but this is kinda the point. If I can think it, a sizeable portion of the population can as well. The difference is that it just made it now is easier to deploy in non-benign manner. My concern is not with terror orgs. Those can and do their own thing. I am worried about a casual kid, who uses it for 'pranks' that will happen, as they seem to invariably eventually do, to go too far.

> The only reason I am not expanding on it is because I do not want to give people ideas.

Well and because your ideas are either fantasy land or old hat.

You realize anyone can throw a rock off an overpass and sometimes people actually do it right? People just choose not to.
The two situations are not alike. People choose not to throw rocks directly as the action is direct, immediate and likely against the law with all the things that it would influence. On the other hand, we have a remote system capable of dropping things on unsuspecting heads in an automated manner.

Do you really not see the difference?

One is easy an people don't do it, while one is complicated and people don't do it.

You could drop stuff from a drone or have a drone shoot a gun too, but people don't want to hurt other people in general.

What scenario is in your head that you think being able to drop something and hurt or kill someone is going to happen more if people can do it automatically?

Who are these people that aren't hurting anyone but are suddenly going to do it once it becomes a science project?

(comment deleted)
I had a longer post and deleted it. We disagree. Lets leave it at that.
There is no evidence or explanation here, you seem to just be saying that if people can hurt other people with some sort of automation they will, but you're not explaining why that would be or giving any examples of it happening.
You don’t need to aim that well with a nuclear bomb.

This sort of tech could clearly be applied to the “last mile” problem in hand grenade deliveries as well, so close range jammer based solutions seem pretty hopeless (I think that’s been pretty obvious for a while, but this hobbyist project really emphasizes the fact, right?)

Surely, if this got into the wrong hands evildoers could lower all sorts of things people order:

Toupees

Pianos

Air conditioners

Enriched yellow cake uranium

Specially trained mice with machine guns

Robert De Niro in Brazil

Etc etc

We must mobilize to stop this now before it’s too late. Hopefully this will be addressed during next week’s presidential election.

I'm old enough to remember fishing poles hanging out of windows in Alphabet so you could buy drugs.
Yes, imagine if someone dropped a certain red cap with writing on it totally unbeknownst to you. People might form Opinions about you!
I love this kind of project.

A lot of states are working on legislation that includes requirements for watermarking AI generated content. But it seldom defines AI with any rigor, making me wonder if soon everyone will need to label everything as made with AI to be on the safe side, kinda like prop 65 warnings.

I'm guessing we'll just end with every website has a button where you have to accept:

[ all cookies and ai stuff ]

This is not quite like the "AI" that's hyped in recent years, the key component is OpenCV and it has been around for decades. Few years ago, this might have been called Machine Learning (ML) instead of Artificial Intelligence (AI).
You have discovered a secret area of my personalized "pet peeves" level: just a few days ago I saw an article (maybe video) about how "AI" tracks you in a restaurant. Screenshot was from an OpenCV-based app with a bounding box around each person, it counted how many people are in the establishment, who is a waiter and who is a customer, and how long they have been there.
Image recognition is AI.
Maybe it is easier to define what isn't AI? Toshiba's handwritten postal code recognizers from the 1970s? Fuzzy logic in washing machines that adjusts the pre-programmed cycle based on laundry weight and dirtyness?
Those both sound like AI to me

An example of similar computer can do that isn't AI would be arithmetic

Adding two numbers, each having 100 digits? Reciting the fractional part of Π on and on? I have only seen that done by talented people appearing in TV shows. Seems AI.
Historically, we often call something AI while we don’t really understand how it works. After that it quietly gets subsumed into machine learning or another area and called X algorithm.
There's an old saying: "Yesterday's AI is today's algorithm". Few would consider A* search for route-planning or Alpha-Beta pruning for game playing to be "Capital A Captial I" today, but they absolutely were back at their inception. Heck, the various modern elaborations on A* are mostly still published in a journal of AI (AAAI).
Apparently there was a big scare that AI would take programmers' jobs away... decades ago, when the first compilers came out.
Yes, no more machine code. Everything was to be written in BASIC. ...how we laughed at that outlandish idea. It was so obvious performance would be... well... what we have today pretty much.
IKR? If you can't hand-pick where instructions are located on the drum, you may have to use separate constants, and if that's the case what is even the point?
If you spend a few hours writing a bit of code that has to run for decades, millions or billions of times per day on hundreds of thousands or millions of machines it seems quite significant to use only the instructions needed to make it work. A few hundreds of thousands extra seems a lot. One would imagine other useful things could be done with quintillions or septillions of cycles besides saving a few development hours.
We will likely develop more accurate names for the different shades of AI after the fact. Or the AI will.
This is a fair point and maybe someone more well versed can correct me but pretty much all state of the art image recognition is trained neural networks nowadays right? A* is still something a human can reasonably code, it seems to me that there is a legitimate distinction between these types of things nowadays.
A* is definitely AI... Why would someone say it isn't?
As a data point in my early 2010s computer science bachelor program it was taught to me as the A* algorithm.
Right, in an AI class. For example, lecture 5 in 6.034: https://ocw.mit.edu/courses/6-034-artificial-intelligence-fa...
No, in an introduction to data structures and algorithms class. It’s pretty odd behavior to disagree with someone who is simply sharing their lived experience.
Same class name with the same algorithm for me.
Yeah sorry, rereading, that came off as way aggressive for no reason. Rereading the chain, I think I just meant that it’s an algorithm that was frequently taught in AI classes, so at least some profs think it counts, even though it was called an algorithm.
same as parent, it was taught to me in an introduction to algorithms class, and no one during my academic stay ever referred to it as an AI.

I don't disagree that it certainly meets certain AI criteria, just saying that particular phrasing (A* is AI) was never used.

Thank you! I was wondering how they managed to wedge an AI model into a RasPi. And I couldn't figure out what the AI was needed for.
Looks like the key component is roboflow (a computer vision/ai platform) and the user trained and deployed a yolo deep-learning model.
That's my point: legislation seldom defines AI rigorously enough to exclude work like OpenCV. I presume that leaves it to courts or prosecutorial discretion.
So it doesn't actually drop hats onto heads and doesn't use what most people would consider AI... I think I could probably rig up something to gracelessly shove an item out of an open window too which is basically what we're left with. It'd take longer to create the app for booking appointments, and to set up everything for payment processing.
Be it "AI" or not, these mostly fall under "AI" legistlation, at least in the new EU AI Act. Which is IMHO a better way to legislate than tying laws to specific algorithms d'jour.
It’s going to be like those “made in a facility that processes nuts” warnings that are on most foods these days
This comment is known to the State of California to contain text that may cause you to ignore warnings which may lead to cancer, reproductive defects, and some other shit that I can't remember because it's been almost a decade since I lived in California and weirdly I can't easily find the full text of one of these online through a quick search (emphasis: quick)
I fear you’re right — cookie banners will soon also come with endless AI disclaimers that net net desensitize the end user to any consideration as they seek to skip poorly crafted regulation and get on with their lives.
Poorly enforced regulation. Most of the cookie banners are illegal but businesses, especially large ones, have too much power to be effectively regulated.

The nags are kind of malicious semi-compliance, partly in effort to make the regulation look bad.

If Big AI lobbyists get their way, this is exactly the kind of warnings we'll get.

Flood users with warnings on everything and it'll get ignored. Especially if there's no penalty for warning when there isn't a risk.

Big Tobacco must love Prop 65 warnings, because by making it look like everything causes cancer, smokers keep themselves blissfully ignorant at just how large the risk factor is for tobacco compared to most other things.

Ok folks, how does this impact our AGI (Aerial Gear Installation) timelines?
I think it has already propelled us ahead by 2 years.
Propelled us a head, eh?

I see what you did there.

This is beautiful. Have you ever dropped a hat on someone's head a a surprise?
will this create an organic HN meetup next under this dudes window?
Finally someone accomplishes something meaningful with AI! /s
[flagged]
You will need to book a spot first
He seems to be already fully booked until the 13th of August, must have been really successful, or maybe just the result of the exposure on HN? Hopefully people aren't booking spots just to troll.
The exterior photos provide enough info that you can figure out the intersection/building if you’re curious
This is ABSOLUTELY RIDICULOUS.

I can’t believe someone would spend the time and effort to do this.

I love it. You’re brilliant.

looks like AGI has been achieved externally
Oh I could use this to deliver my home made lunch boxes to customers from my 15th floor apartment!
I'm no AI expert, but I think you could do that with some twine.
Twine would bias delivery to the right recipient whereas pure AI can send it anywhere with a high degree of inaccuracy.
I feel like such a killjoy, but the first thing I thought of is the ongoing lice “epidemic” among people with school aged children in NYC.

I have never liked it when the ACs drip on me in midtown let alone a hat dropping on my head!

My hats are completely new and unworn! Lice free since June 23
This is a consensual hat, not a villainous hat that attacks virgin tops.
Although I think the idea of nonconsensual hat drops is so fun and fantastic.

I wish I could register myself as being up for any sort of serendipity like this. While I like the idea of a hat randomly dropping onto my head, some people may not.

you have to request the hat lol, you dont just walk buy and get shit dropped on you, you book a drop
As a counter point, the hat is a great way to protect against AC water drips.

My biggest fear about walking around any city (but NYC in particular) is an actual AC machine dropping onto my head. Maybe you could offer the choice to drop down a hard hat on streets with high AC unit density (and then pick it up when I leave the area).

Love this! I play recreational ice hockey in an Adult league and for the past many years I've desired to use AI/Object recognition to recognize who was out on the ice during what times during the game to attribute who impacted goals and which players were taking longer than usual shifts ( every team has those one or two players!).

This may be achievable for me with the current state of AI and GPT to help fill the gaps that my knowledge is lacking in. Thanks for showing what you made and how you did it. It's encouragement to me.

If only LiveBarn feeds weren’t such a pile of crap I’d have some hope.
This would be interesting, feel free to email me if you get stuck. If you had a camera at eye level, you could try to train it on recognizing the player jersey numbers.
Facial recognition would be better. Don’t forget that canonically in Mighty Ducks D2 Goldberg and Russ switched jerseys so that Russ could get his infamous “Knuckle Puck” shot off undisputed because everyone thought the puck was passed to Goldberg until the mask came off. So the ML training on jerseys would have missed this critical moment and potentially assigned the score to Goldberg, when really it was Russ (wearing Goldberg’s jersey) who should have gotten the credit.

One might argue that this sort of thing rarely happens so it’s not worth doing more complex facial recognition vis a vis Jersey numbering. But I say that while it may be rare, when it does happen it’s a major event, so no complexity should be spared to ensure we capture it accurately.

Typically beer league players wear full face cages so facial recognition is harder to do
Iirc, LiveBarn offers this as a service if your local rink has it set up. Annoyingly, my local rink uses 30 minute video slots so it only ever captures half a game.
I play in a rec soccer league and had a similar idea, except to also have everyone on the team wear a smartwatch that could intelligently buzz at you to sub out based on your heartrate and how long you've been in.
should give this to the coach too - Texas players get heat exhaustion

Trace and hudl use shirt number and person tracking. I bet they could add skin color and gait analysis to do this as well.

This has already been possible for a decade.
I am seeking neighboring stores! Sometimes I crave gum on the street, Gum drop anyone?

To summarize, I used:

1. Low weight but very cool product (like Propeller Hats)

2. Raspberry Pi for controlling everything

3. Adafruit stepper motor for the dropping mechanism

4. Yarn for holding the hat

5. Roboflow for the AI

i work on roboflow. seeing all the creative ways people use computer vision is motivating for us. let me know (email in bio) if there's things you'd like to be better.
This is legitimately awesome. Nice job sir.
> Sometimes I crave gum on the street

My immediate response to this was “ew, there’s already so much gum on the street”. Then I realized you meant you want to chew gum while walking down the street and I became enlightened.

What do you think happens after they have enough of the gum? :)
After gum on the street, there's gum on the street
I dream of a world where I merely open my mouth and wish it and the gum just flies down into it, already unwrapped.

You’re working toward this world and I commend you.

I'll hold out for the teleportation-based version so I don't have to go through the effort of opening my mouth.
I would hope that we have invented error-free software development by then, though. Otherwise, a small error leading to the wrong coordinates could really ruin your day (or head)... ;)
Or use lasers and tiny gum-shaped smoke bombs to sample and model the local air column currents, pre soften and flatten a portion of the gum paper-thin with some sort of wettimg/rolling assembly, stage, then let it drop and form its own miniature gum parachute or replica of one of those whirling propeller seeds that have a built-in wing to slow their fall.
Startup opportunity: AI inside a small in-mouth implant to provide nerve stimulus to open mouth for you when it detects floaty inbound gum.
That does sound convenient. Can it be hooked up to my eyes to detect flies and close my mouth to make sure I don't inhale bugs while biking?
What about a “we will remember it for you wholesale” version of the gum experience - you pay money and are then implanted with memories that are indistinguishable from chewing the gum. I kinda think this is the end goal for all capitalism - you pay money for nothing.
At the speed of gravitational fall, it might choke you!
This is part of the challenge, as I want a pleasant experience. Not a terminal one.
Perhaps small guided parachutes that receive an auto-correction location from the RPi and track the mouth? The issue is that the gum will be expensive.
Maybe a receiving chute? Small, portable, and a clearer indication (cannot be confused with a yawn), plus it'll open up the variety of comestibles you can purchase just s mouthful of. No more forks, no more spoons, just a little sloped thing to slow and guide
People still use gum in 2024? I thought it's a wide knowledge that it's bad for you in every single way
I do, specifically Mastic gum.
Alright, I didn't mean the natural/medicinal gums
Apparently the knowledge isn't wide enough, because this is the first I'm hearing of it... Why is gum bad for you? I knew it was in a downward sales trend, but I figured that was just consumer preferences changing over time.
Ingredients are poor for mouth and gut microbiome, but then again so is mostly everything else that's processed
Gum with sugar is bad for your teeth. Gum without sugar has xylitol in it, which is good for your teeth, but may increase your risk of heart attacks and strokes due to it promoting blood clotting[1].

1: https://newsroom.clevelandclinic.org/2024/06/06/cleveland-cl...

Wait... gum with sugar? That exists?
Yes? Bazooka, double bubble, and big league chew off the top of my head. As well as every gum ball I've ever seen.
Not seen those brands in Sweden, but I checked the one we have that's for kids, a bubble gum named Hubba Bubba. Indeed, it has sugar! TIL.
Why does this remind me of something out of a certain old point and click adventure game, it was one that had the verb USE apply to every type of action.

click>(GUM)

click>(SELF)

click>(USE)

"You used the GUM on yourself.

Nothing special happens.

You now have 0 GUM."

There was another game in the same genre that did the same, but with the verb OPERATE. As teenagers my friends and I used to laugh way too much at dialogue responses these games would craft, where you would get things like "OPERATE GUM on SELF"

Well according to the gum brands it's good for your teeth. I've never heard of any evidence to the contrary, not even from my dentist.
it's good for building up your jaw strength which can be pretty helpful.
Yes, one thing I wanted to mention was to develop/keep the jaw muscles, though eating dense enough food like nuts or dry froots does this too
I am pretty certain sugar-free gum is excellent for preventing cavities by increasing saliva production. That is one way it is not bad for you.
the biggest thing he's overcoming is the rent?! how's he doing that while goofing off with projects like this?
Slightly unrelated: Did the building owner/landlord complain about that? Is it legal?

I know a friend of mine whom the building asked to remove a camera they had. It was a camera used only to record the hill view in front of the building, so it isn't violating any privacy, and it was attached with magnets, so no damage whatsoever.

I was also curious about this. a bunch of BASE jumping hats dropping off a building is exactly the sort of project I would momentarily think about doing and never seriously entertain due to being certain that sooner or later someone, somewhere is going to sue me for some marginally harm-like side effect.
I don't know how litigous your region is but of all the people you know who have been sued, how many of them got sued for something silly vs a more low effort scheme like the classic throw yourself onto someones car and have 'back pain'? You might be safe to do silly shit on the basis that there are easier and better targets available.
Also curious if they had any grounds for that. I was under the impression that if you have a camera within your apartment (looking through window), nobody should be able to tell you no.

Unless perhaps the camera was attached outside their window (no longer their apartment), in a way that could be deemed unsafe and fall off and hurt someone, whereupon the building owner could be held liable? In that case I would find it reasonable to tell them to remove it.

> Unless perhaps the camera was attached outside their window

I remember it was on the balcony, securely attached. The building simply cited their policy, not any laws nor safety issues.

There’s plenty of gum already on the street. Simply scrape it up and you can have all the gum you desire.
What if we had like a fridge with glass window and drinks or snacks organized in rows with identifiers for each. You could enter the identifier and make your payment to the fridge and it would drop the corresponding drink/snack to a slot on the bottom of the fridge.

Really, really liked it! Also, would be glad to hear where you got that helicopter heads. I've been looking for one for some time but my head is large sized so I can't find one that fits here where I live.
[flagged]
(comment deleted)
Can you go a bit more in depth for the part regarding training the Ai to recognize the heads? Like what software(s) did you use ecc... I'm an undergrad who's seeking to do similar computer vision internships for his thesis and I find this kinda fascinating
That would most likely be the OpenCV bit
No the opencv was just to capture video frames and they were iediately passed to the roboflow model through the ssh client.
Which is what many would also call 'Image Processing'
Fantastic, I love this kind of silly stuff. The clear next iteration is a 4-prop hat, which can be guided to the target head.

Of course, that starts to verge on what's spooky about the idea, but either way, this is really fun and cool.

This is one of the most beautiful things made with AI
Typical mid-western humor, spends almost as much time describing how to open a window as how to build an AI agent. Very fun project.
All experiences are equal. They all come and go. Its the ego which gives higher importance to building an AI agent over opening a window.
Well now I feel bad for laughing and having a good time.
Typical mid-western Buddhist humor.
From a fellow midwesterner - was this great? “You betcha!”

Finally some window shopping that interests me.
