24 alternatives to 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!

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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    There are lots of RTL-SDR applications, but you have to install them. I used the HTML5 USB API that exists in Chrome (did you know about it?) to build one that you can run straight from your browser, on your computer or your Android phone.

    Hi everyone! Shortly after publishing my iOS 4 jailbreak last October[1], I got to work on my next hobby project: a from-scratch homebrew GPS receiver, which can solve the user’s location solely from billions of radio antenna samples. I took a commodity SDR (alongside the Python standard library and numpy) and built a signal processing pipeline that can detect and track GPS satellites over many minutes, drop and pick up satellites as they come in and out of view, and precisely determine the user’s position and clock inaccuracy. All told, gypsum can go from a cold start to a fix on the user’s…

    I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions!

    Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution (https://github.com/cjjeakle/network-monitor), feel free to clone and try it out! I know there are a lot more mature monitoring…

    Hello Hacker News! I’ve been having some fun recently and I wanted to share with you. My idea was to feed ChatGPT an image and ask for a caption, feed that back to DallE, then call this in a loop, and observe how the image that was generated changed over time. Similar to playing the game “telephone”. The results were really intriguing, so I built something that you can play with. Note this is best on a desktop (streamlit is optimized for a large screen), but if you’re on mobile you’ll want to expand the sidebar to start — it’s the carrot on top. My initial intention was for you to be able to…
