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.

Hey programmer,

If you are a developer, vibe coder or just interested in building stuff I have one opportunity for you I am joining one hackathon, and just need one good team so we can build together if you are interested just let me know in comments or DM

- I need a vibe coder, frontend, and builder

- form India specific or if other countries dm me time zone

- No experience of it's your first that's ok just need independent thinker and good at programming with AI

The story

I have participated in 5 reddit games hackathons in the past and I've not won anything major. In the first 4 hackathons, I felt that the winning games were good, but not all games justified the submission and grading criterias well. In the lastest hackathon - Games with a hook hackathon, though - a lot of people raised concerns on how the winning game did not "wow" them.

Here are some examples below:

1. Devpost discussion-

Concerns on whether the hakathon was fixed

2. Comments on the reddit announcement post-

Concerns on quality of winners

Generic response from the admin

They were not entertaining any personal feedback stating that there were over 3000 submissions. But if a game was judged fairly, the judges should have written down something about the game! Or atleast they could provide the scores. I had sent them a personal email requesting feedback, but hadn't recieved any response from them. The next day, I got a $500 helper award from the devpost team. According to the original winner announcement, I had not won any award. I had responded to the organizers asking if this was a mistake. They said that it was indeed sent to me by mistake, but it was sent to me because reddit had put forth my name.

If I accepted the award, I had to sign a paper that says I cannot sue reddit. I didn't accept the award. Something was suspicious here so I started investigating.

Problems with the judging process -

1. Mystery judges?

Usually hackathons list down the judges with their credentials. You can go to the list of all reddit hackathons on devpost and none of them have the name of judges.

Reddit hackathon judges

Here are some samples of how the judge list looks like in other hackathons -

Univabio $35k hackathon judges

a $75k google hackathon judges

2. Negligence / Judgement not thorough -

I had reached out to 3 other participants and got the list of players from each of our games. Based on the list, there was not a single common player across the 4 games. This could only mean one thing - our games were not played by the judges. Here's an anecdote from one of the participants -

The only participant who had any activity in their game

There was another participant who claimed that they had attached a video to their submission. Throughout the duration of the judging, the view count had not changed in the youtube video. -> The judges had not viewed the submission video (video was <1 min long)

3. Ghost winners -

The reddit hackathons were to encourage developers to make games on the platform. The expectation from every hackathon is that the winning game has a big community and continue to grow the community by making their game better.

Here's a list of all the reddit hackathons in the past from latest to first.

Competition	Winner	Amount won	Sub weekly visitor count
Games with a hook hackathon	r/SketchySolutions	£15,000	276
Daily games hackathon	r/bridgedit	£15,000	10
Kiro: Community games challenge	r/SoulThieves	£15,000	1300
Kiro: Community games challenge	r/blockrift	£10,000	-
Fun and games with devvit web	r/OnelineGame	£15,000	42
Fun and games with devvit web	r/hexaword	£15,000	?
Hack reddit	r/chook	£20,000	6
Games and Puzzles hackathon	r/EmojiCharades	£20,000	43
Games and Puzzles hackathon	r/pixel_together	£20,000	3
Games and Puzzles hackathon	r/DailyDungeon	£20,000	4

Note that I do not look to disrespect any creator here. I know a lot of hardwork had gone into your games and that deserves recognition. But there are also a lot of other creators whose hardwork has amounted to nothing.

4. Judges prefer "flashy visuals" over long term value

This here is my weakest point so far. But to some of you, it will be the biggest takeaway of this post. Mentally picture the winner of a google hackathon. What kind of entry do you envision? You expect it to be creative, well thought out, crazy, nerdy etc. right?
Based on my past 5 hackathons I don't think these virtues are valued in reddit hackathons -

#1

Hackathon: Games and Puzzles hackathon
My entry: Outwitquiz
My thoughts: Since the game was supposed to be on reddit, I created an equivalent of "Psych" which can be played asynchronously by all users on reddit. This was an entry for the word games category. The winning entry was emoji charades. I get that the winning entry was made well and polished, but why does this game have to be on reddit? It could be a standalone website!

#2

Hackathon: Hack reddit
My entry: Angels vs Devils
My thoughts: This made me the most sad. The overview of the hackathon said "Build a new game, social experiment, or experience on Devvit". So I thought I'd build a social experiment where users play a community minesweeper. I had built up many game modes that I could work on. The winner r/chook, was a game where you grow your chicken and feed it food by pressing buttons. (it was beautifully made though)

#3

Hackathon: Fun and games with devvit web
My entry: Divide n conquer
My thoughts: Based on past two hackathons, I stopped making experiments and designed a game. It was a game where you have a limited line length, you draw lines to capture land in a country and try to occupy the most land area and landmarks. I thought it was well thought out and fun to play, but it was not polished. I don't have many problems with this hackathon. I did good work and was sad I didn't win anything, but the winning entries truly deserved it.

#4

Hackathon: Daily games hackathon
My entry: r/totalled
My thoughts: I had won an honorable mention for this game. For this hackathon, I had kept my game concept simple and made a very well polished game. It is a game where you have to swipe across numbers in a 3x3 grid to create totals. Once you accomplish 3 totals, the game is over and you're ranked based on the time taken. Of all the games I've made so far, this is the most "Linkedin-y". I expected to win more, based on the past winners. When I saw the winner, I was shocked! An entire physics sandbox inside reddit! It was crazy good work, but I was surprised that the judges thought this game would be played regularly. Why would a reddit user play a physics sandbox daily? And why is it on reddit?

#5

Hackathon: Games with a hook hackathon
My entry: r/ShadowChess
My thoughts: Based on the previous hackathon, I believed now that the judges don't just look at "will this game be played daily". They also valued grand experiences. So I knew for sure the idea I had for this hackathon wold win. This was the best game I had ever made! Its a massive multiplayer chess game where you continue off of grandmaster positions and make 5 pre-moves. The opponents make the 5 pre-moves as well and your moves are pitted against each other based on a customized scoring system. This fit the hackathon criteria in multiple ways and had potential to do great. I feel so betrayed that the game was not even played once! My game is good when there are 100s of players playing it. It could have really used the boost of players from any sort of recognition. This hackathon was all about creating a "hook". Here's the words on the hackathon page -

\"progression, daily challenges, fresh content, social dynamics\" - my game had it all

Now you can't look at my above entries and say that none of these games deserved any award except "totalled", (which was one of my weakest entries). Especially shadowchess. Note that apart from the winner, there's 10 honorable mention awards for every hackathon.

Overall, I feel that it's best to avoid spending all that time and effort on reddit hackathons. Atleast until they bring in some transparency into the judging process.

I expect a response from the reddit team on this. Anyone who participated in this hackathon, feel free to DM me with your thoughts / information.

Hey everyone — we're running a 2-week online hackathon and looking for fresh eyes, — 10 winners × 150.

We built Walrus Memory — it gives AI agents persistent memory that works across Claude, Cursor, Codex, and other tools. Your agent actually remembers you between sessions instead of starting from scratch every time.

Our community already built 6 working prompts for it. Now we want people to pick one up, use it for real, improve it, and write about what happened. The best improvements may find their way into the official docs.

The 6 prompts cover:
Cross-agent handoff — pick up unfinished work across AI tools without rebuilding context

Creative writing — stop contradicting your own characters, timelines, and world rules

Developer productivity — preserve decisions and fixes across projects and hackathons

Studying — surface your recurring mistakes and build revision sessions from your own history

Multi-project memory — carry preferences and history between tools

D&D campaign memory — track NPCs, quests, lore, and events across long campaigns

No coding required. If you can use an AI tool and write a blog post, you can participate.

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.

Our college is about to organize its internal SIH Hackathon and wanted to know some insights about other colleges like how it went and how the statements were selected. If you could provide some info about your college, it'll be a great help.

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

Anyone got the results for tresure hunt??? Sabko dena hai kya round 1???

Need it ASAP!!

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.
