    Hello all, This is my second year of working on a project[1] with the goal of browsing the web, on an Android smartphone, without reliance on Wi-Fi or mobile data. While this concept might seem aimless, my goal was to provide a way for people in areas with limited, expensive, or censored cellular internet access a way to view the web in a basic format. I finished work on a basic client-server model last year[2], and this year, I implemented a new pseudo-distributed peer-to-peer model that allows any TxtNet Browser user to use their own smartphone to run a background server service that…

    I’ve always liked having background noise while working or falling asleep, but I got frustrated that most “white noise” or ambient sound apps are either paywalled, stuffed with ads, or try to upsell subscriptions for basic features. So I made Ambi, a small iOS app with a clean interface and a set of freely available ambient sounds — rain, waves, wind, birds, that sort of thing. You can mix them, adjust volume levels, and just let it play all night or while you work. Everything works offline and there are no hidden catches. It’s something I built for myself first, but I figured others might…

    Hi HN, r2t2 is a command-line tool for transmitting data through sound using the PC speaker on the motherboard. The name of the tool is a reference to the R2-D2 robot from Star Wars :) In short, you type some message and it gets FSK modulated and transmitted via sound through the PC speaker. Note that this is the speaker/buzzer that you connect to the motherboard and not the regular speakers that you connect to the sound card. I also made a simple web page that listens to the sound emitted by r2t2 and decodes the received messages. The page can be used by simply opening it on your phone…

    I built this free, no-nonsense white noise app. I know there are plenty of them out there already, but I wanted to make something beautiful and easy-to-use, without logins or ads or in-app purchases or any of the other stuff a lot of them have. I appeared on The Economist's The Intelligence podcast [0] this week talking about Ambiphone and another ambient music project, Ambient ScotRail Beats [1] - I'm on at about 17:30 There's a big selection of music and sounds already but I'm always adding more - if there's anything you'd like to see added, let me know!
