Show HN: I built a handheld CHIP-8 game console to teach myself embedded systems
A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier).<p>But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system.<p>I didn't know much about embedded software when I began, and even less about electronics, but I managed to write all the firmware from scratch and even designed my first PCB, resulting in a finished (though not very polished) handheld CHIP-8 console.<p>For those curious, the GitHub repo also has links to my dev blog about the project as well as a build guide.<p>Thanks for looking!

Show HN: I help LGBT people to find LGBT homes
My Gay Flatmate helps the LGBT community to find a safe place to live.
It is a 2-sided platform. People can advirtise their spare room, and they can also create a profile to say they are looking for a room.<p>Happy to receive some feedback!
I am a solo founder (not by option)

Tell HN: My new free note taking tool
So there are a lot of posts here about personal knowledge databases & note taking apps ... and methodologies. I wanted a way to keep track of info & just as importantly be able to easily see & edit that data from anywhere.<p>I wanted it to be robust, free, web-based, able to host code examples as actual files (e.g. style.css or script.js), and host images.<p>Turns out this is all available with Github & Gitlab.<p>Step 1: Create a Private Repo
Step 2: Hit the . key or use the editor URL pattern: https://github.dev/{{username}}/{{repo-name}}
Step 3: Start using ... you can add sub-directories with Markdown for notes ... you can add all the file types above.<p>For Gitlab just click "Web IDE" from your project's homepage.<p>(I made this URL: https://github.dev/{{username}}/{{repo-name}} my homepage, making it super easy to access.)<p>This is absolutely nothing new; but the epiphany I had a week or so ago about using a repo in this way seems to have really stuck (yes, a week is a short period of time but often a note app or approach sticks for a day or 2 for me).<p>I'm really curious if others do something like this & what other sorts of practices they might employ while doing this.
Show HN: I built a self hosted recommendation feed to escape Google's algorithm
I created this chrome extension for myself where I track my own behavior locally and recommend myself content from platforms I want content from (youtube/twitter/quora/etc) in a feed. I made it public just in case anyone else was interested.<p>I would rather have control over my own algorithm and own the data. Also, it gives me flexibility. Turns out I do like these feeds just not when I don't own it haha. Let me know what you think of my implementation?

Show HN: PubKey – Communicate Privately in Anonymous Public Spaces
A little while back I remember seeing a user on a certain anonymous imageboard asking for an invite to a selective email host. Only after a few minutes did the guy realize the perplexity of the situation. How do you insure against a race condition in a public forum with no way to direct message?<p>Luckily, he nabbed the invite code, but it got me thinking about using PGP to provide a solution. This is meant to be a rough PoC and the UX is definitely not ready for the average Joe, but the functionality I'd like to think is there.<p>What catbox.moe is to dropbox is what I'd like this to eventually be to keybase. Btw, "this page uses NO SERVER" just means it's static. I'm not trying to fool anyone lol.<p>Edit: Source Code: <a href="https://codeberg.org/popcalc/pubKey" rel="nofollow">https://codeberg.org/popcalc/pubKey</a>
