Is the next leap of electronics brain organoids?

stanto — Sat, 28 Feb 2026 16:39:09 GMT

There's not a loud majority talking about this tech' at the moment, but it's somewhat concerning. Using stem cells groups are "finally" combining electronics and organics, notably stem cells. Doing everything from running Doom (of course) to running LLMs on/with them. This should be raising all sorts of questions.

Gabriel Torch does a great job at summarising legit research papers on this topic.

I made a Lightweight Fingers Detection model That dosent uses any Training Data or any AI and is almost accurate

Aniket_kumar_raj — Fri, 27 Feb 2026 15:13:50 GMT

Do you know where was i For a few Days....

I was Grounded home with no internet so i made something that i was not able to find on internet... but first lets start from beginning to explain everything .look at this thing

www.youtube.com/.../TsgXpnmGRMQ

I saw this short in my Short feed and tried to create it but the one thing required was a lightest hand detection model, but none ai could make it and i wasn't able to find any on internet , then i took everything in my own hands and made this code that detects fingers smoothly, but dont move your face in box, only hands are allowed in the green box

here is the code that i made roasting my 1.3 megapixel camera of 17 years old laptop that i use for daily study..

to use this you must have these liblaries in python --->

cv2 , numpy , math

I did add comments so its easy to understand and variables are good too

Computer network design: Replacing the coffee-break napkin discussion.

colporteur — Wed, 02 Jul 2025 22:08:27 GMT

I am looking for input from members in the E14 community that have computer network experience. The block diagram is the drawing of a small farming business network.

The network is one IP subnet spread across three physical locations. The subnet has about 50 IP consumed across the three areas. The edge router is in the office. Wireless point-to-point devices connect the seed-plant and residence to the office.

Inside the seed-plant and residence are routers that route the programmable logic controller and home devices, respectively. This routers will remain. What is happening behind the seed-plant router is expanding.

My plan is to replace the current edge router with a router capable of creating multiple networks. Four subnetworks to start: office, seed-plant, residence and wifi-guest-network that doesn't exist today. These networks will be interconnected and have internet access. The new edge router will isolate the the wireless guest-network and provide internet access only. I hope to combine the VPN access into the router and eliminate the VPN appliance.

One valuable resource I miss since retirement is coffee-break time with the team. It was not uncommon for someone to start a discussion on a napkin drawing. The napkin formed a centrepiece for group discussions.

I’m looking for that napkin discussion with members from the E14 Community. I encourage you to ask questions and provide feedback. Even if you don’t have computer networking experience, please join the discussion. Answering your questions may flush out some ideas I wasn’t thinking about.

After retiring, I took on the role of break-fix for the company that owns this network. Now that the network is stable, and the company is proposing expansion, I feel it is time to implement the network plan I created five years ago.

What are your thoughts?

what is the most underrated use case of AI and Machine Learning you've come across?

CalvinTerence — Tue, 01 Jul 2025 04:24:18 GMT

We often hear about the big stuff - self driving cars, Chat GPT, facial recognition. But there are so many smaller, less flashy applications that are quietly transforming industries. Maybe it's AI in agriculture or machine learning in supply chain optimization, or even something quirky like AI that monitor animal behavior. what's one use you think should get more attention than it gets?

Would you trust ChatGPT to cook your food for you?

stanto — Thu, 20 Mar 2025 00:58:23 GMT

www.youtube.com/watch

I don't know, maybe we should? Frankly if I can't read the timings on the back of a box, this makes this kind of food pretty accessible, if questionably safe.

Get your python and raspberry pi out and get microwave cooking I guess!

Is there an alternative to ChatGPT where I don't have to pay for an API to do this? I guess a decent trained model's hard to run locally.

So called Machine Vision/AI is actually Human Vision/HI

HKPhysicist — Fri, 27 Dec 2024 16:20:16 GMT

I have finally found out that the so called AI Machine Vision is actually HI (Human Intelligence) or Human Vision.

Those big tech companies outsource huge tasks of identifying and tagging visual objects in real world to "blood & sweat" software factories which in turn hire huge amount of human labours to tag objects in our everyday living. It goes without saying that wages of labours in "blood & sweat" factories are super low.

It is the whole background of the so called autonomous driving or Machine Vision.

Then, we add the good old scientific core of Cybernetics and Control System Engineering, we will have a so called autonomous vehicle.

Tri automatique de déchets

maxesme — Thu, 07 Nov 2024 09:03:04 GMT

Bonjour,

Pour notre projet de fin d'année en école d'ingénieurs à l'ESME Lille, nous travaillons sur un collecteur de déchets intelligent.

Pour cela, nous avons pensé à intégrer l'IA pour la reconnaissance des déchets.

Voici la problématique que nous avons :

"Nous aimerions entraîner nous-mêmes sa base de données (par exemple, une base de données pour le carton, le plastique, le verre, etc.), puis contrôler des sorties du Raspberry en fonction de l’objet détecté."

Nous avons pensé dans un premier temps à un Raspberry avec la nouvelle Pi AI Camera, mais ne sachant pas s'il est possible d'entraîner sa propre base de données, nous aimerions savoir s'il existe d'autres solutions qui pourraient répondre à cette problématique.

Nous restons à votre disposition pour toute information supplémentaire.

En vous remerciant d'avance pour votre retour.

Cordialement,
Maxime Poillot

Hello Everyone

I am working on project creating smart glasses.

Need Power-full/ultralight/ultra-small board to integrate in glasses.

I need to install YOLO on it and some other custom made/open source software.

Motly will use for object detection and recognition.

Jatson Nano is powerful, but I cannot fit it in glasses.

Please if anyone have experience to recommended any SBC which I can use for tasks listed above.

What I need to Achieve.

I am working on Smart Glasses for visual impaired people.

I need to detect and recognise objects and analyse relief (I will use LIDAR sensor as well) + some more functions.

Need SBC, which can do this job and prefer lightweight to hide it in smart glasses.

Many thanks

Do you want to run your own local 'ChatGPT' ? Now you can.

cstanton — Fri, 31 Mar 2023 10:02:36 GMT

You may have heard about Meta's LLaMa leak - well, if you register for them via a google form it's not exactly a leak, but it's certainly not for commercial use.

Since then people have investigated whether or not you can run it yourself.

https://github.com/ggerganov/llama.cpp (or its spin-off alpaca.cpp)

You can. What's more is it uses the CPU rather than GPU, and the models can be refactored to run on only 4GB of RAM.

That's right, you can run your own "ChatGPT" on a Raspberry Pi.

There are options to 'scale' it to use more or less processing cores, and its responses can take about 280ms, but with a bit of fiddling and tweaking, it runs!

It certainly benefits more from faster data storage for its models, particularly when processing them.

Now who's going to jump the gun and get it working with home automation and produce their own 'Travis' from Iron Man ?

Using AI and Machine Learning in Embedded Software Development

suriyakumar — Fri, 17 Mar 2023 10:00:39 GMT

Hello everyone,

I'm interested in discussing the intersection of AI and Machine Learning with embedded software development. With the advancements in technology and the rise of the Internet of Things (IoT), AI and Machine Learning are becoming more integrated into embedded systems.

I wanted to start this discussion to explore how AI and Machine Learning can be utilized in embedded software development. Here are some questions to get us started:

What are some examples of AI and Machine Learning being used in embedded systems?
How can AI and Machine Learning improve the performance and efficiency of embedded software?
What challenges are there when integrating AI and Machine Learning into embedded systems?
What tools and resources are available for developers interested in integrating AI and Machine Learning into their embedded software projects?

Please feel free to share your experiences and thoughts on this topic. I'm excited to hear what everyone has to say!

ChatGPT not logging into my account ?

Maker434 — Sat, 11 Mar 2023 19:52:23 GMT

I created my first account in ChatGPT 1 months ago but suddenly since last 3 weeks I am unable to log back into my openai.com account why is that ??

Now when I open in the browser openai.com I am unable to find the login page?? Is this happening due to the geographic region or something else. I want to use ChatGPT but unable to ??

Please any help appreciated ??

How do I create 'checkpoint' files?

cstanton — Tue, 21 Feb 2023 12:55:13 GMT

I'm mainly working with Stable Diffusion, and it relies on trained 'checkpoint' or ckpt files, but I can't seem to find any reliable guidelines on how to create these 'from scratch'. They almost always suggest or recommend starting with an existing file?

Which I want to avoid, especially with all of the issues over copyright and trademarks using existing graphical content.

I'm simply not sure where to start, searching online for this tends to result in useless youtube video guides that simply point me to download other files, etc. I'd rather have an open source tool solution.

Is anyone else playing with these tools at the moment? Linkin Park's 'Lost' has somewhat inspired me to dabble with it.

In their music video, they've used cuts from footage of the band, and used the 'stable diffusion' type of AI generation as a filter, along with original animation art, and trained the filter on that animation art. So what you get is a mixture of original pieces, some AI weirdness and amazing effects:

www.youtube.com/watch

I've played around with this myself on a video, it took about 1-2 minutes per frame to render it out and then recompile back into a video, but I'd want to train it on a checkpoint I'd had full control over instead.

What is the impact of artificial intelligence on society?

vijaykumar — Tue, 17 Jan 2023 10:40:13 GMT

Think of compound interest. All of the technological advancements we have today are compound interests of our knowledge and discovery over thousands of years. As time has passed, it has gotten faster to over hundreds of years, and then to over tens of years. Now we are at a time where every two years we advance a little more and every ten years we leap. Any thoughts on this?

Does anyone know about K210 Dual-core RISC-V 64bit Boards ?

gsgill112 — Wed, 12 Jun 2019 18:56:58 GMT

I was surfing the web and stumbled upon K210 Dual-core RISC-V 64bit Boards ...

another one Here and they pretty cheep for about 800 INR for the Module with Wifi ...

And these claim to have KPU(Neural Network Processor) inside, 64 KPU which is 576bit width, support convolution kernels, any form of activation function. It offers 0.25TOPS@0.3W,400MHz, and when you overclock to 800MHz, it offers 0.5TOPS. It means you can do object recognition 60fps@VGA.

Isn't that Coollll.....

Ref:-

https://www.indiegogo.com/projects/sipeed-maix-the-world-first-risc-v-64-ai-module#/

and even BananaPi has then in their dev boards ..

Nvidia Jetson Nano: AI and Deep Learning

ipv1 — Sat, 06 Apr 2019 05:21:15 GMT

I am working on Machine Vision Applications and OpenCV is my current tool. I was not considering deep learning till I saw the Nvidia Jetson Nano Board which is good on paper.

I am awaiting some funds from a few clients in India and will be getting the board myself but before I do, I wanted to know if someone has any experience with TensorFlow, OpenCV or the like with Nvidia boards?

Thanks
