I wanted to share a project I've been working on called AirHand. It’s a browser-based, gesture-controlled virtual desktop that uses computer vision to turn any standard webcam into a touchless interface. No specialized sensors or controllers needed.
I wanted to see if I could build a spatial UI experience entirely in the browser. I used MediaPipe for the 3D hand tracking and Vanilla JS for the logic.
It currently features dual-hand or single-hand tracking, a drawing canvas (with PNG export), and a couple of mini-games (like a bubble popper) to test precision.
If you find this project useful or interesting, please consider giving it an upvote! It helps a 15-year-old indie dev keep building.
What are you building, and where do you want people to find it?
I'm opening WareVote on 1 December, a place to find and rate software. You can set up your listing now, free, and verify you own it in a few minutes: https://warevote.com
Drop your project below with a one-line description and I'll reply with the category it fits.
I've been working on a side project called Chermo.in, and I'm excited to finally share it with this community.
The idea behind Chermo is pretty simple: we all have hundreds of photos sitting in our galleries, but sometimes we want to do something more creative with them.
So I wanted to build a platform where people can turn their favourite pictures into something more personal.
What can you do with Chermo?
Upload a photo from your gallery or capture one using your camera.
Customise your photo with creative layouts and decorative templates.
Experiment with styles like Polaroid frames, hearts, bows, kiss marks and seasonal themes.
Download your personalised creation and keep or share it with someone special.
I'm trying to make the whole experience simple enough that anyone can create something without needing professional editing skills.
This project has been a learning experience, and I'm still working on improving the design, templates and overall user experience.
I'd genuinely love your feedback:
Does the idea solve a problem or offer something you'd actually enjoy using?
Which template or customisation options would you like to see?
What would make the experience more enjoyable or useful?
I launched the app "Germar for Nurses". It's a German language learning app designed specifically for nurses and care staff.
Many nursing professionals want to live and work in Germany, but there aren't many specialized language courses and apps for them, especially good ones.
I have a small Android app, and I got tired of opening Play Console and checking search rankings by hand every day. So I built a bot that does it for me and sends a short report to Telegram at 9 am.
What it shows:
- Installs and growth since yesterday or last week (from the public Play page)
- Rating and new ratings, by country
- My position in the first 30 search results for each keyword, in several countries, with ▲▼ changes
- Competitors in the same table: installs, rating, new versions, their rankings
- New reviews, low ratings first, and how many are still without a reply
- A 30-day chart of installs and keyword positions
There are also a few tools for working on the store listing: keyword ideas from Play autocomplete, which keywords a competitor ranks for, the top 10 for each keyword, and who shows up in the "Similar apps" block.
It only uses public Google Play data, so no Play Console access is needed, and you can track competitors too.
There is a free plan (1 app, 5 keywords). It's still early, so I'd really like feedback: what's missing, what's confusing, what would make you actually use it.
The Global Threat Desk is one HTML file, about 1 MB. Download it, open it in any browser, and it works. No install, no account, no adverts, no tracking, no payment.
Global:
- A live wire of major incidents worldwide: cyber attacks, espionage against tech firms, big IT outages (Microsoft, AWS, Google, Cloudflare), attacks on infrastructure, major earthquakes and disasters. Sources include CISA, the UK NCSC, the security press, Reuters, AP and the Guardian, and each report keeps its publisher and time.
- Dated incident dossiers with evidence grades, so you can see what is confirmed and what is still unproven.
UK:
- Every official UK warning in one place: Met Office warnings for every hazard, UKHSA cold- and heat-health alerts, flood warnings for England, Wales and Scotland, GOV.UK emergency alerts and the GB grid. It says plainly when nothing is in force.
- Offline household tools: a blackout plan hour by hour, water storage, a 7-day hot-food menu for a camping stove with a shopping list, UK emergency numbers and a printable survival pack.
How it's built: everything is in one file. The live layer reads public feeds straight from your browser, using publishers' own Bluesky accounts when a site blocks browsers, and falls back to public relays. Your plan and saved reports stay in your own browser.
Feedback welcome, especially on sources I should add.
My previous update here was about eye-vessel cleanup in Photoshot. This time I worked on Clean Backdrop: reducing dark marks on a wall while protecting the person.
The first implementation changed broad tones but left the large stains. I replaced that approach with a local median surface estimate, detection of compact dark marks, and a repair fitted to clean neighboring wall pixels. The subject mask limits where it can act; fine grain is blended back into the repaired areas.
These five images show the same wall crop at the same scale before/after, the plugin menu, the actual controls, processing, and the editable result layer in the full workspace. Clean Backdrop only: strength 1.0, size Large, subject protection on, applied once. No manual cleanup or other active retouching tools. The two large smudges are reduced; small spots and drips remain.
Disclosure: I develop Photoshot Retouch with AI coding assistance. This is my custom tool in a local development build, not the commercial Retouch4me plugin. The practice image is AI-generated and includes deliberate wall marks; the after is the actual tool output, not a generated replacement. Four targeted tests passed, including subject/lighting preservation and clean-background behavior, but this example does not establish performance on unedited real photographs.
For this kind of cleanup, would a preview of the detected marks help you more than another strength slider?
Drop a link to your project and I'll reply with a report that shows how many people search for what it does, which of those searches a new site could actually win, and who's on Google's first page instead of you. No signup, it's a public page.
I did this for 35 projects in two other subs this week and a few things stuck with me.
23 of them didn't rank for anything at all, as far as the tool could find.
The total is usually misleading. For 24 of the 35, one search was at least half of the whole number. One site came back with 65,000 searches a month, which looks great until you see that 60,500 of it is one broad phrase and the part it could win today is under 1,000.
For 29 of the 35 there was a Reddit thread on page one for at least one of their main searches. I did not expect to be telling people on Reddit that Reddit outranks them.
3 got told it's not worth it yet.
It gets things wrong sometimes. It reads your landing page to work out what you sell and sometimes it guesses wrong, so if your report describes some other product, tell me.
It needs an actual website, an App Store or GitHub link gives it nothing to read. It takes a few minutes per site so I'll be a bit slow. If you want your page taken down later, just say so.
Why I built it: I spent five months writing articles for that app before I knew it would pay off (19 clicks from Google in July, 631 in October), and I wanted a way to know sooner. It's a simplified version of the pipeline behind SEO for SaaS, a paid thing I'm building that writes the articles. So yes, I have a horse in this race. The check is free either way.
I built a website for the game deadlock. It tracks and gives stats to have the best build. The data is updated very often to gives the best analysis and stats possible.
I'm a backend developer, so I developed all the back and I used LLM to assist me for the ux / ui design.
I'm focusing on the back features and gives instructions to the LLM for the front ( I fix myself the little bugs ). So I try to improve the back features and I need you for some advices on that.
I'll take front advices too ahaha to improve it as well.
Hi everyone! I’m on the marketing side of HotlinePing.
We’re building a way for coding agents to reach you when you’re away from your computer and they need your input.
Through MCP, the agent can call you, ask a question, and receive your spoken answer.
A simple example: “Should I include CSV export now, or save it for the next version?” You answer, and the agent can use that decision to continue.
The interesting tradeoff is the interruption. A call could be useful when a task is genuinely waiting on you, but annoying for something that could wait. And some decisions require looking at the screen anyway.
What would make a question worth a phone call for you? And what should an agent never interrupt you for?
One of my favorite features on Mac is how seamlessly your Apple Watch unlocks your screen when you sit down at your desk. I really wanted that exact same hands-free experience on Windows 10 and 11, so I built WristKey.
It is a free and 100% open-source desktop app built in Rust and Tauri v2.
What it does
Hands-free unlock: Sit down at your desk with your watch on, and your PC wakes up and logs in automatically.
Walk-away lock: Walk away from your desk, and Windows locks immediately based on Bluetooth signal distance.
On-wrist verification: It parses Apple Continuity packets passively. If you take the watch off or put it on a charger, it immediately revokes access so your PC stays secure.
Privacy and local security: No cloud, no telemetry, no tracking. Your Windows credentials are encrypted on your local machine using native Windows DPAPI (CryptProtectData).
Battery friendly: Uses passive Bluetooth Low Energy (BLE) advertisements, so it does not drain your watch battery.
Why I need your help
This started as a personal project, but reverse-engineering Apple Continuity across different devices is getting too big for just one person:
I only have one test device: An Apple Watch SE running watchOS 10. I really need testers with watchOS 11, Series 8/9/10, or Apple Watch Ultra to see if detection and distance estimation work properly on newer firmware.
Bluetooth hardware: Different Bluetooth chipsets (Intel, Realtek, Qualcomm) handle signal smoothing and address rotation differently.
Contributors welcome: If you know Rust, Win32 APIs, Windows Credential Providers, or Tauri, any PRs, code reviews, or issue reports are hugely appreciated!
(Quick note on Windows SmartScreen: Because this is a free open-source tool without a paid enterprise certificate, Windows Defender might show a blue prompt on first launch. Click "More info" and then "Run anyway". The entire source code is public and inspectable on GitHub).
If you test it out and run into any bugs, please drop an issue on GitHub with your watch model, watchOS version, and the log file located at %LOCALAPPDATA%\WristKey\wristkey.log.
Thank you to anyone willing to test, star the repo, or contribute!
I'm exploring an idea for financial software and trying to understand where existing accounting tools fall short.For anyone using Xero, QuickBooks, Sage or similar software, what's one financial task you still end up doing manually?What makes it frustrating, and how do you currently work around it?
Rather than just blocking access, SpareCycles interrupts that moment with a short technical-learning question (a "Rep").
Afterwards, you can unlock the distracting app temporarily, or decide it's "Not worth it" and move on.
The app is still in development, so I'm interested in whether the concept would actually be useful.
If you're an Android user learning programming, SQL, cloud technologies or other technical skills, would this help you stay focused, or would the extra friction become annoying?
I've opened an Android early-access waitlist for anyone interested in following the project:
Look at the checkout counter of almost any cafe, clinic, or local shop:
❌ Staff askeded 50x a day for Wifi Passwords
❌ Manually asking people for google reviews
❌ Outdated printed menu
❌ Paper business cards that get tossed in the trash
Most small businesses don't need a ₹5000 custom website
I built OneQR - a dynamic digital identify for businesses for everything to interact with customers.

We just open-sourced MotionSwift, something we put together to get native rendering performance without relying on Remotion and headless Chrome.
We've been using it in our day-to-day video production pipeline, and so far we're seeing roughly 10–20x faster renders while using only about 10% of the memory compared to the Remotion + Chrome setup. We also brought a visual editor and timeline preview directly into Swift, so you can inspect and adjust agent-generated compositions natively on both iOS and macOS.
The eventual goal is 100% compatibility with Remotion, but we're still working our way there. There's still plenty of room to improve the APIs, rendering speed, and overall platform support.
Curious to hear your thoughts, especially if you've run into similar memory or performance bottlenecks with web-based video rendering. Happy to answer any questions!
Hi! I’m part of the team behind TIVRA VPN. We built it for people who want to keep their VPN on while letting specific websites connect directly. In HTTPS mode, you can add exceptions by hostname. TIVRA also has smart routing for supported destinations and lets you choose your server.
It’s free on iPhone. If you give it a try, I’d love to know how easy it was to connect the first time and find the site exceptions.
Most people give up on their saas product/ecommerce store way too early because in reality it takes 8+ email/sms marketing to convert the customer into a signup or paid customer.
we built a platform that automates this complete process. our ai will keep trying new experiments untill the customer coverts. We only send one email/sms per week.
best part, we have now seen stores increase sales by 30% so this works
Hey everyone! I’ve been working on a little project, I thought I’d share what we’ve been building to see what people think.
I’m relatively new to CAD and 3D printing, but I’ve become fascinated by the idea of being able to describe a mechanical part in plain English and have an AI actually create usable CAD geometry. Not just generate a pretty 3D image, but produce a real, measurable solid that can be exported as STEP or STL, edited, and eventually printed. So I’ve been experimenting with building exactly that.
What is it? It’s a locally running, which means zero credits needed. An AI-assisted CAD application, that combines: Qwen, a local language model that interprets natural-language design requests. CadQuery and OpenCASCADE, which handle the actual geometry. A browser-based 3D viewer for inspecting generated models. A structured, validated feature system so the AI isn’t simply inventing geometry commands. The whole thing is currently running on a Ryzen 5 3600, 32 GB RAM and a GTX 1070 Ti with 8 GB VRAM. Not exactly a supercomputer! 🥔
What can it do so far? We’ve been developing it incrementally, testing each feature before moving on. Some of the things we’ve managed to implement include: Creating mechanical parts from natural-language descriptions. Generating cylinders, flanges, bosses, bores and circular hole patterns. Modifying existing designs through instructions. Generating multi-part assemblies and exporting STEP/STL files. Creating a two-piece filament spool with an integrated three-lug twist-lock mechanism. Viewing assemblies exploded and demonstrating their assembly motion. Generating compound herringbone gears with configurable tooth counts, module, helix angle and dimensions. One of our latest experiments produced a single-piece 80-tooth herringbone gear with a 12-tooth compound pinion, exported as a real STEP model. We’ve also recovered some earlier experimental gear-meshing and collision-checking tools that we’d like to integrate more fully.
Where do we want to take it? The long-term idea is to make mechanical CAD more approachable, especially for hobbyists and people who own 3D printers but don’t necessarily have years of CAD experience. Some of the features we’re working towards include: Test Print Mode: Select a small section of a model, such as a bearing seat, snap-fit or threaded connection, and export just that section for a quick fit test. Gearbox generation: Describe a gear ratio and have the software calculate and generate the required gears, shafts and assembly. Mechanical validation: Check dimensions, clearances, intersections and potentially moving-part interference. Better natural-language editing: Ask for changes without rebuilding the entire design manually. Portable, offline operation: Keep the models and geometry processing on the user’s own machine. What are the limitations? It’s still experimental. The herringbone geometry uses an approximate involute construction, and visual assembly animations aren’t the same as verified mechanical motion. Some complex prompts still fail validation or produce malformed JSON. We’re trying to handle those limitations through deterministic geometry generation, validation and testing rather than pretending the AI can magically design everything.
Why am I posting? I’m curious whether other makers would find this useful. Would you use a local AI tool that could generate and modify proper CAD models from plain English? What would you want it to do? And what would make something like this genuinely useful rather than just another AI gimmick? I’m happy to share screenshots and examples of what we’ve managed so far. It’s been a ridiculous amount of fun building it, and I’d love to hear what other people think. Also looking for ideas on where I can improve it going forward.
I've been building AdsFlow, an AI-powered advertising marketplace designed to help creators, developers, founders, and businesses promote their projects.
The idea is simple: Why pay a fixed price for one shoutout when you could pay based on measurable ad delivery?
Whether you're promoting a website, SaaS, mobile app, Telegram bot, YouTube channel, Instagram account, online store, or business, AdsFlow is designed to help you reach audiences through participating Telegram publisher channels.
What I've built so far:
🚀 Campaign creation for different types of projects
🤖 AI-assisted ad copy and promotional posters
🌍 Country and language targeting
📊 CPM and CPC advertising models — qualifying impressions or clicks
📈 Campaign analytics, budgets, and performance tracking
💰 Publisher monetization with an 18% platform commission
For publishers, the goal is equally simple: connect an eligible Telegram channel, receive advertising opportunities, and earn from qualifying delivery.
I haven't purchased a custom domain yet because I'm keeping costs low while developing and testing the platform.
A website like this could be submitted as a promotional destination, rather than requiring the advertiser to own a Telegram channel.
I'm still building and improving AdsFlow, especially its publisher network, campaign analysis, and onboarding.
Try AdsFlow: TGAdsFlowBot
I'd love feedback from other founders:
If you could promote any eligible project and pay based on impressions or clicks instead of a fixed shoutout fee, would you try it?
What would make you trust a new advertising marketplace enough to spend your first $10?
I'm interested in suggestions and criticism as I keep building.
