Show HN: I built an offline open-source RAG system DataBridge https://bit.ly/4gIC2Vc

Show HN: I built an offline open-source RAG system DataBridge Hey HN! Over the past few weeks, I’ve been working on DataBridge, an open-source solution for data ingestion and querying across text, PDFs, images, and videos. In our latest update, we’ve added a fully local deployment option: - No internet required – Runs entirely offline. - Customizable Models – Supports any LLM and embedding model via Ollama (with options for any other private providers) - Extensibility – You can plug in your own models or tools easily. This local-first approach ensures better privacy, security, and flexibility, especially for teams dealing with sensitive data. You can check it out here: Docs: https://bit.ly/4j2RMnv Code: https://bit.ly/4fy0eZ2 If you can try it out, would really really appreciate it :)). Any and every feedback welcome. https://bit.ly/4fy0eZ2 January 6, 2025 at 07:53PM

Show HN: Filter out engagement bait & politics on your X/Twitter feed. https://bit.ly/423yuIK

Show HN: Filter out engagement bait & politics on your X/Twitter feed. hi friends! i'm pretty tired of engagement bait and all the political nonsense on my x/twitter feed. i was curious if i could use an llm to filter out these type of content, so i prototyped a quick chrome extension. it uses LLama 3.3 to analyze the tweet through https://bit.ly/3BLH7Np (because they are super-super fast). the extension is available in the chrome store, also there is a link to the repo. - you can tweak the system prompt for the filtering - but you need your own API key from Groq (you can get one for free) https://bit.ly/4gGeVe1 January 6, 2025 at 10:49AM

Show HN: E-Paper Life Organizer with Pico and Inky Frame https://bit.ly/3WaM1KD

Show HN: E-Paper Life Organizer with Pico and Inky Frame I made a desktop e paper display to show my calendar and to-do list to help keep me organized in college. Full source code available here: https://bit.ly/4gHeRuq The display is only awoken from deep sleep mode every 30 minutes to update the information, allowing the frame to be fully battery powered. You can link your Todoist for the to-do items on the left, and you can link any calendar in iCal format (Google Calendar, Outlook, etc.) for the calendar on the right. The code can be fully customized to display just the calendar, just the to-do list, or a mix of both. Let me know if you have any ideas for what features I should add next! https://bit.ly/4gHeRuq January 6, 2025 at 04:40AM

Show HN: LogLayer – Unified logger that routes logs to various logging libraries https://bit.ly/421mozO

Show HN: LogLayer – Unified logger that routes logs to various logging libraries As a longtime TypeScript/Node.js developer, I've often faced challenges with logging—choosing, using, and maintaining the right logger for various projects. While most loggers offer the usual methods like "info", "warn", and "error", they vary significantly in how they handle structured metadata or Error objects. This can lead to ad-hoc solutions, like serializing errors or writing custom pipelines, just to get logs formatted correctly. I built LogLayer to address these pain points by introducing a fluid, expressive API. With methods like "withMetadata" and "withError", LogLayer separates object injection from the log message itself, making your logging code both cleaner and more maintainable. Logs are processed through a LogLayer Transport, which acts as an adapter for your preferred logging library. This design offers several key advantages: - Multi-Transport Support: Send logs to multiple destinations (e.g., DataDog and New Relic) simultaneously. I've personally used this feature to ship logs directly to DataDog without relying on their APM package or sidecars. - Easy Logger Swapping: If you’ve ever used Pino with Next.js, you might have encountered issues where it doesn’t work out of the box after a production build without webpack hacks. With LogLayer, you can swap in a better-suited library without touching your logging code. I spent a good few months on and off and used my winter break to launch version 5 of LogLayer, and also created the documentation using Vitepress. LogLayer has been battle-tested in production at Airtop ( https://bit.ly/3BN9I4W ), where it’s been an integral part of our systems for years (we were running as Switchboard for almost four years and pivoted late last year). (Disclaimer: I work at Airtop, but LogLayer is not sponsored / affiliated with them.) https://bit.ly/421HLAV January 6, 2025 at 01:52AM

Show HN: I created a PoC for live descriptions of the surroundings for the blind https://bit.ly/4a7fVVL

Show HN: I created a PoC for live descriptions of the surroundings for the blind The difference in cost between products that are developed as accessibility tools compared to consumer products is huge. One example is camera glasses where the accessibility product costs ~$3000 (Envision Glasses), and the consumer product costs ~$300 (Ray-Ban Meta). In this case the Ray-Ban Meta is getting accessibility features. The functionality is promising according to reviews, but requires the user to say "Hey meta what am I looking at" every time a scene is to be described. The battery life seem underwhelming as well. It would be nice to have an cheap and open source alternative to the currently available products, where the user gets fed information rather than continuously requesting it. This is where I got interested to see if I could create a solution using an ESP32 WiFi camera, and learn some arduino development in the process. I managed to create a solution where the camera connects to the phone "personal hotspot", and publishes an image every 7 seconds to an online server, which then uses the gpt-4o-mini model to describe the image and update a web page, that is read back to the user using voice synthesis. The latency for this is less than 2 seconds, and is generally faster. I am happy with the result and learnt a lot, but I think I will pause this project for now. At least until some shiny new tech emerges (cheaper open source camera glasses). https://bit.ly/40lbbsE January 4, 2025 at 11:41AM

Show HN: I completed shipping my desktop app Hi, I'm a developer and first time i shipped the real product after observing the startups and indie hackers community for years. I had made so many useless apps [you should check my website https://bit.ly/4gWELdg ], but this time I built a very useful product that has a number of super easy-to-use tools in one app for video, music, and photo files. Users can compress, convert, resize, and do so much more with easy-to-use tools. Background: I developed a frame-by-frame video cropper to upload cropped landscape videos to Instagram Reels. However, it required FFmpeg, and as a noob video editor, I decided to incorporate more user-friendly video tools. I then introduced image and audio tools to maximize the capabilities of FFmpeg. I use my app daily, and it has surprisingly generated a few thousand dollars for me. https://bit.ly/4gWELKi January 3, 2025 at 01:20PM

Show HN: AI that generates 3blue1brown-style explainer videos https://bit.ly/4fRX02Q

Show HN: AI that generates 3blue1brown-style explainer videos I've been building prototypes of new AI learning tools for months, but I recently learned that 3blue1brown open sourced his incredible math animation library, Manim, and that LLMs could generate code for it without any fine-tuning. So I made a tool that automatically generates animated math/science explanations in the style of 3blue1brown using Manim from any text prompt. Try it yourself at https://bit.ly/40l0p5F (no signup required) The UX is pretty simple right now, you just write a text prompt and then start watching the video as it's generated. Once it's done generating you can download it. I built this because I kept finding myself spending 30+ minutes in AI chats trying to understand very specific concepts that would have clicked instantly if there were a visual explanations on YouTube. Technical Implementation: - LLM + prompt to use Manim well, right now this uses Gemini with grounding to ensure some level of factuality, but it works equally well with Claude - Manim for animation generation - OpenAI TTS for the voiceovers - Fly.io for hosting the web app - Modal.com for fast serverless GPUs to render the videos - HLS protocol for streaming the videos as they are rendered Note: This is focused on STEM education and visualization, and it is particularly good for math, but get creative and try it with anything! I used it recently to teach my partner's parents a new board game in Mandarin (which I don't speak!) I'll be around to answer questions. Happy learning! https://bit.ly/40l0p5F January 3, 2025 at 11:44PM

Show HN: MailMock – Simplified Email Testing for Developers https://bit.ly/40gwMSM

Show HN: MailMock – Simplified Email Testing for Developers I work at a software consulting company where we often face the challenge of testing email functionality in non-production environments. Typically, email sending is disabled in development and staging, making it difficult to verify whether emails are formatted correctly or even sent at all without making significant code changes. I experimented with self-hosting an SMTP server, but the maintenance overhead was too high. This led to the idea for MailMock, which offers a simpler solution: by simply changing the SMTP credentials, you can redirect emails without the need for server management or code rewrites. MailMock is a tool designed for developers to test emails in development and staging environments. It captures emails into dedicated test inboxes, allowing you to validate your app's or website's email flow. Features include multi-user collaboration and an email retention policy of up to 90 days, making debugging and testing easier. On the technical side, MailMock is built using C# for the backend, React for the frontend, and SQLite as the database. You can try MailMock by signing up [here]( https://bit.ly/40huIdm ). Once you sign up, you can create a project and immediately start testing by changing your SMTP settings to point to our service. Let me know what you think, or if you have any issues or suggestions! https://bit.ly/40gGEvN January 2, 2025 at 03:49AM

Show HN: I built a green noise player to help you relax, focus, and stay calm https://bit.ly/40eTkU5

Show HN: I built a green noise player to help you relax, focus, and stay calm Sometimes, I struggle to block distractions and create a calming environment while working. Most tools I’ve tried were either cluttered, didn’t provide the right kind of sound, or required payment. So, I decided to build my own simple green noise player. For context, green noise features balanced, mid-range frequencies that mimic soothing natural sounds—ideal for relaxation, focus, or creating a peaceful backdrop while working. It’s also great for taking a mindful break during a busy day. Right now, it’s a free, lightweight, browser-based solution. Playback pauses on mobile when the screen locks, but I’m exploring ways to improve it. Maybe a dedicated mobile version in the future? Would love to hear your thoughts and feedback! https://bit.ly/40gwrzt January 1, 2025 at 11:19PM

Show HN: API Parrot – Automatically Reverse Engineer HTTP APIs https://bit.ly/40ffLbA

Show HN: API Parrot – Automatically Reverse Engineer HTTP APIs When automating business processes at work, I found it difficult and time-consuming to reverse engineer business systems' APIs. I often had to manually reverse engineer APIs using developer tools or settle for less optimal technologies such as Robotic Process Automation (RPA). Often, the issue is that it can be hard to resolve all the cookies, access tokens, and other elements required to successfully execute the requests. Manually trying to resolve these dependencies using developer tools is especially challenging with multiple requests where data is stored in JavaScript objects or HTML elements. To try to solve this issue, I built a tool called API Parrot that automatically identifies the data correlations between requests and builds a graphical representation of the flow to give users a better understanding. To streamline the process, I also included functionality to record requests, define your own inputs and outputs, and export the entire flow—or parts of it—as JavaScript code. The application is Electron-based and currently compiled for Windows and Linux. Please try it out and give feedback!
