I built an Android app where you can chat with people on the same battery percentage

Hey everyone, I recently launched a small Android app called Mavora, built around a strange but simple idea: your phone battery percentage can become a temporary social signal. If your phone is at 42%, the app can show other anonymous users who are also around the same battery level. You can send them a signal request, and if they accept, a private anonymous chat opens. The idea is not to make another dating app or location-based social app. I wanted it to feel more like ambient anonymous ...

CLI YouTube player in Rust that renders videos as ASCII art

I built a terminal-based YouTube video player that renders videos as ASCII art in real time. To make this work, I also built a reusable image-to-ASCII rendering engine as a separate Rust crate, which the player uses to convert video frames into ASCII and stream them to stdout with basic FPS control. Projects: ASCII engine (Rust crate): https://github.com/SameerVers3/pixel2ascii Terminal YouTube player: https://github.com/SameerVers3/stdout-tv It’s mainly an experiment, but I’d ...

I made an app that automatically lowers your music when game dialogue plays, then brings it back, and lets you control it from your controller

been building this solo for the last few weeks. it's called Segue. the idea: your music should react to your game instead of you alt-tabbing to manage it. it auto-lowers your music when game dialogue plays (real speech detection, not a timer), then brings it back. it does the same for Discord, ducking your music when your friends talk so you can talk without the music being in the way. you can also control everything from your controller, swipe the DualSense touchpad for volume, swipe to ski...

Everything is connected to everything — I made a tool that shows you how, and narrates the journey

It lets you connect any two topics and see the path between them, along with a short story of how they’re linked. You can also add a stop in between if you want it to route through a specific topic. In the video: I connect Albert Einstein with Cristiano Ronaldo and it shows the full path and story Then I use “Surprise Me” and it connects Cleopatra with Coca-Cola Along with this, there are other sections like: Atlas — a collection of interesting and surprising connections Pas...

Going off Reddit has helped validate my project

I’ve posted about my weather game occasionally here on Reddit over the last month, and almost universally it’s been ignored or downvoted. A few honest and helpful feedback reviews have come through, but by and large it’s not been a great experience. I have a pretty decent LinkedIn connection pool from my 20+ years of being in technology, so I figured I’d try there to get some early feedback and users from there. It’s been so refreshing! And it’s not just “friends and family” on there. I’ve ...

I built ChromiumFish: Chrome + native AI agent for Playwright

Hey r/SideProject, I built ChromiumFish , a fingerprint-hardened Chrome with drop-in Playwright support for Python and Node, and built-in AI Agent support at the C++ level. I know most of you are gonna smell the chromium, but rest assured, this fork tries its best to pretend like a Chrome running on a Windows machine. The reason I built this is that when you are running your browser on a Linux machine, there are lots of telltale signs that it's a Chrome running on Linux. That's what I tri...

I built a Claude Code skill called /brag that turns your side project into a launch video

People around me keep telling me about cool stuff they built but it often ends at that, so I built /brag, a skill that helps people actually show what they made. /brag lets you brag about what you built by simply telling Claude "hey, let's /brag about this." Under the hood it uses HyperFrames (HeyGen's open-source HTML-to-video engine) to render a short, ~20-second launch video, complete with music and sound effects, that's easy to share. It's free and open source, has several styl...

I built a free site to connect missing-person records with unidentified bodies in India

In India, when someone goes missing, the police record is in one place. When an unidentified body is found, that record is in another place. These two lists never meet. They sit in different states, different police systems, none of them connected. So a family looking for their missing person has nowhere to check if an unidentified body somewhere else could be them. A match that should happen, just... doesn't. I made JSKMU to connect these two sides. A family adds their missing person. T...

I built an AI tool that watches your tennis match and tells you what happened (open beta)

Quick background: I play tennis [a very little bit], and the thing that always bugged me is you finish a match with a feeling but no information. The good rally, the footwork that fell apart in the third set, all gone. Pros have analysts. The rest of us have memory. So my co-founder and I built Wingball. You record your session the normal way and upload the clip to our webapp. It tracks every shot, cuts an auto highlight reel, and gives you a court heatmap plus stats like distance covered, to...

I built my first website around the way my ADHD brain follows curiosity trails

Hi everyone! I just launched my first website/side project and would love some honest feedback. I have pretty bad ADHD, and I’ve always had this pattern where one simple thought turns into a whole trail of connected topics. I might start with a movie, a weird historical fact, or a random question, and somehow end up reading about mythology, philosophy, psychology, or theoretical physics. Traditional advanced learning never clicked very well for me, but curiosity-based learning always did. ...

I built one of Android's early photo-alarm apps back in 2016 - I just spent months rebuilding the whole engine by hand for modern Android

Back in 2016, waking up to your own photos basically wasn't a thing on Android - so I built it. A photo-based alarm clock, one of the early ones on the platform. It picked up around 10,000 downloads and a bunch of reviews from people who loved waking up to their own pictures instead of a stock ringtone. Then life happened - burnout, a day job - and in 2021 I unpublished it and walked away. It nagged at me for years, so a few months ago I opened the old project. It did NOT survive the decade:...

I created AI CBT journal app

https://dialectic.neonflume.com/ A lot of journaling apps either feel like blank documents or try to act like therapists. I wanted something in between. Instead of simply asking "How was your day?", it actively engages with your thoughts using guided questioning inspired by CBT and Socratic dialogue. For example, if you write: "I messed up a presentation today. I'm terrible at my job." It won't just store the entry. It may ask questions like: What evidence su...

I'm testing a "one tiny thing a day" before building anything

I'm a builder, 15 years in product + tech. I know what I should do, I just can't start, and the evening disappears into scrolling. The idea: once a day you get one tiny nudge to do a small thing, small enough that starting is basically impossible to fail. Stand outside two minutes. Open the task you've been avoiding. Put one mug away. You reply DONE or SKIP. This is anti social media and usual dopamine addiction, there will never be a friend system, no streak, no scrolling behaviour. Before ...

I got tired of "gamified" coding sites just being basic progress bars, so I built a raw React/Canvas tower defense engine from scratch to teach algorithms.

Hey r/SideProject , I wanted a coding platform where the game mechanics were actually tied to the code logic and optimization, not just arbitrary XP points. So over the last 18 months, I’ve been solo-developing CodeGrind.online . The Tech & Build: Instead of using a heavy game engine like Godot or Unity, I built the entire thing using standard React and a raw HTML5 Canvas engine . It’s completely vanilla JS (no TypeScript for this one, keeping the canvas rendering pipeline as stre...

Made a Tamagotchi that runs on your AI coding tokens (free, runs locally)

I use Claude Code all day, and the only thing that ever comes out of all those tokens is a number going up in a billing dashboard. Felt like a waste of a perfectly good signal, so I made something fun with it. It's called Tokengotchi, basically a Tamagotchi that eats your tokens. You run one command, it reads your local usage logs (same files ccusage reads, nothing leaves your machine), and a tiny hero turns that usage into "energy" and auto-battles through an idle dungeon while yo...
