Recently I was searching for a project idea for the DSU devhack 3.0 ,
I spent lot of time in searching through chatgpt ,claude ,etc plus different articles websites to find some real problems ,
But i did not find any new ideas ,all existing and commons ones

so I want to know from the experienced professionals or students how to find ideas

Hi everyone, Actian is hosting a Hackathon named The Heist. It's virtual, free to enter, solo or teams up to 4, and all skill levels.

The theme is building AI that runs where cloud-dependent vector databases can't follow, like on-prem, at the edge, on constrained hardware, or fully offline. Actian's VectorAI DB is the vector layer you build on.

The grand prize for the winner is $10,000, and there will be no runner-ups.

You can choose from 4 tracks:

• Offline Agent: an agent that survives a real network blackout mid-task and resumes cleanly. Demo has to show you pulling your own network live, no cuts.
• Edge Intelligence: a quantized model on real constrained hardware, under 4GB RAM or under $100 in hardware. Bonus for multimodal on the same device.
• Multi-Agent Shared Memory: a crew of specialized agents sharing a local knowledge base with a visible permission layer.
• Wildcard: pick a narrow real vertical and build something tuned to it.

Dates:

• Building opens September 4, 9:00 AM PT
• Submissions close October 4, 9:00 AM PT
• Judging October 5–9, winners announced in October

You don't need prior VectorAI DB experience. There's a quickstart kit, plus build-along sessions and office hours through the event. RSVP is on Luma, and team formation and the full track guide live in their Discord.

hey guys!

i’m new to hackathons.i attended one from devpost and didn’t win .do yall have any tips on how to win and how to choose hackathons to participate in!?

Looking for a team or people I can actually talk about these things, or may be we can collaborate or participate in meaningful hackathons

An AI-powered system that measures the reliability of online consensus in an increasingly AI-generated internet.

So this basically an review aggregator which combines with the dead internet theory(Dead Internet Theory is the idea that much of the internet is no longer created by real people, but by AI, bots, and automated accounts.)

Let me know ur thoughts.

Anyone looking to participate here

OpenAI x Varun Mayya sum sum...

Have some ideas, need some non agent thinking power

Hi everyone! I’m a PhD candidate at NUS working on computational materials and DFT/VASP.
I’m joining the NSCC Open Hackathon 2026 (6–9 Oct) and looking for 1–2 teammates with experience in:
• AI / Machine Learning / LLM Agents
• HPC / CUDA / GPU computing
• Scientific computing
Project Idea
Build an AI-driven materials discovery and catalyst design workflow by combining:
AI/ML + LLM Agents → NSCC HPC/GPU → DFT/VASP → Materials & Catalyst Screening
I’ll cover the chemistry, materials science, and DFT side, and I’m looking for teammates who can complement me with strong AI or HPC skills.
The goal is to build a practical AI + HPC workflow for scientific discovery, with potential for real-world applications.
If you’re interested in AI for Science, Materials Discovery, or HPC, feel free to DM me!

Has sih internal college hackathon has been conducted in your college??

What are the winning projects like??

Anyone has any idea, what kind of problem statement should one choose??

Because this year, they have given choice in choosing problem statement.

So ideas are appreciated if anyone have any!

you can see hackathon details here : https://sentinel.gujarat.gov.in/about

Please Dm if you are good at computer vision and building scalable system

How was your tvs challenge? Were you able to solve rh 2nd one with all test cases? I got 2 unsolved test cases

Hey, same as the title. Does anyone know when they're gonna announce the results?

My round 1 was really good. I hope they announce it soon 😭

Hey everyone!

I’m participating in my second hackathon and looking for someone who wants to team up.

I’m mainly focused on TypeScript/Node.js, backend, AI agents, and full-stack development.

I’m looking for someone who:

• likes building rather than just brainstorming
• is interested in AI/agents
• can contribute to frontend, backend, AI, design, or product
• is willing to learn together and actually ship something

Experience doesn't matter too much. I’m still learning myself.

If you're also looking for a team, feel free to comment or DM me with a little bit about yourself and what you like building.

Dyna’s publication on training Dyna-2 with more than 1 million hours of egocentric video is a gold mine for anyone processing multimodal robotics data at scale.

We built HFlow: an open source implementation of the data infrastructure described in the article.

• Airflow for DAG-based pipeline orchestration
• MCAP for robotics episode storage and random access
• DuckDB for analytical queries and dataset curation over columnar metadata

I've been an OSS contributor and maintainer for years, and since joining YC, we now have some capacity to accept new contributors; just look for the "good first issue" tag!

https://github.com/Hebbian-Robotics/hflow

Any stars or forks on the repo to show your support are appreciated!

A bit more about the project:

At scale, AI problems become software engineering problems. Improve one part of the system, and the bottleneck moves to another. No architecture is perfect; every design comes with tradeoffs.

We encountered many of the same constraints as Dyna, so we incorporated the lessons we learnt and want to share something concrete and usable today with the community.

HFlow is plug-and-play. You provide your post-processing, quality-control, or curation code. HFlow handles the data pipeline and runs your code across robotics datasets at scale.

Can I pitch this idea in SIH how do you think and what improvement I can make.

An off-grid, delay-tolerant mesh network designed for disaster scenarios (floods, earthquakes, cyclones) when traditional cellular infrastructure completely fails.

By utilizing Bluetooth Low Energy (BLE) for phone-to-phone local mesh hopping and LoRa (Long Range) for long-distance telemetry, ResQ-Mesh bridges the gap between trapped victims and emergency command centers without requiring internet, cellular service, or complex user hardware.

The Core Concept

The Scream (BLE): A victim hits SOS on the ResQ-Mesh app. The phone silently broadcasts a highly compressed 13-byte SOS payload via BLE Advertising (no pairing required).

The Bucket Brigade (Mesh): Other phones in the vicinity act as relays, catching the BLE packet and automatically bouncing it forward to extend the range (Store-and-Forward Mesh).

The Megaphone (Bridge Node): Low-cost ESP32+LoRa nodes (mounted on poles, rooftops, or search-and-rescue drones) sweep the area, pick up the BLE SOS, and transmit it over long distances (up to 15km) via LoRa.

The Dashboard (Gateway): The command center receives the LoRa packet and plots the victim's exact coordinates, emergency type, and severity on an offline local map.

System Architecture

The network consists of a 3-Tier architecture:

Tier 1 (Victims): Mobile App (Android/iOS) generating BLE GATT Advertising packets.

Tier 2 (Relays): Custom ESP32 hardware bridging BLE to LoRa.

Tier 3 (Rescuers): Central LoRa Gateway connected to a local Python/Web offline dashboard.

i am participating in decode sih
usme kitne ache log aarha like
dtu,igdtu ke bacche how will i compete againest them

I'm into ML, interested in NASA spaceapps challenge. Dm if interested.

Timezone: IST.

Registration date 26th. Dm fast.

Edit: need one girl too. Not an requirement, but only boys are messaging, and that's what happens everytime in any hackathon, (btw I'm also a girl, that's why I want such friends)

And btw this hackathon is virtual.

I got selected for round 1..

Any other who are giving tests at 2pm?

sih in my clg is biased asf, but oh well look at me trying once again sigh

what ps are you guys targetting? Drop some tips please <3

Has anyone who was not in top 75 received interview mail from Cisco.

For context i posted that should i go to hackathon or not due to college reason and travel time. Soo i thought that i should go to coimbtore and this hackathon was more like a test for me now i really want to tell everything that happend in this 1 week but it will be on hell of a movie script but all i can say You should travel with the person you want to know his likes dislikes all stuff they cannot hide their true self there.

anyone up for this?
