Web App Uses RTL-SDR to Align HDTV Antenna

I was sick of losing the Telemundo signal during World Cup, so I built a Web App that uses a local RTL-SDR dongle to analyze the HDTV signal and help you point your antenna... GOAAALLLL!

In plain words

This web application helps users align their HDTV antennas by analyzing broadcast signals through a local RTL-SDR dongle. The tool visualizes signal strength and quality in real time, allowing users to adjust antenna positioning for optimal reception. It's designed for anyone frustrated with weak or intermittent TV signals, particularly useful for receiving specific channels consistently. The application runs locally in a web browser and works with affordable RTL-SDR hardware.

    I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

    I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

    Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

    Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  • Getting GLM 5.2 running on my slow computer▲937

    A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  • OpenSEO▲928

    Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
