Ask HN: Most interesting tech you built for just yourself?

Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

One of my big "side projects" over the last few months has been my personal website and blog (https://epiccoleman.com). It's not very interesting per se - I mean, who doesn't have a blog these days - but it has been really educational and fun to work on. It's a really simplistic stack which makes working on it pretty frictionless. I spent a lot of time tweaking the look and feel of the site and am pretty happy with how everything has turned out.

I've also been putting a lot of work into a React component that renders a nice looking SVG Circle of Fifths, and just recently got to a point where I felt I could call a release "1.0.0". This has also been a really educational project and I'm super proud of the component. It's a little basic right now, but it looks very nice, and I have a lot of cool features planned.

It's licensed MIT, so if this sounds like something you'd like to use in an app, you can check it out here: https://github.com/epiccoleman/react-circle-of-fifths. I'd love any feedback, issues, etc.

Edit: Oh, I just thought of one other thing - a single line of code I wrote which frequently gives me great joy. In zsh you can define a function called `command_not_found_handler` which gets invoked whenever a command ... isn't found.

Mine says: `figlet lol, $@`, so whenever you make a typo like "gits status" or something, you get a big "lol, gits tatus" printed out, which is amusing.

Well that sure looks similar:

https://pine.fm/music/ChordGear

I rotated the inner ring to capture the sense that (for example) Amin shares two notes with Cmaj and 2 notes with Fmaj, so belongs between them.

You can drag the chord gear, click it for a kind of awful synth-piano sound that I had a lot of fun making, switch modes, etc. I actually originally made this in wood/acrylic:https://docs.google.com/document/d/1lwIS-1sPNyIpYM1nCcFkU9Iq... but I like how the online version renames the notes sensibly.)

Mostly I was just trying to explore music theory concepts, and have a few other toys at https://pine.fm/music

(also the code is gross; I've been a manager for almost a decade now and am rusty; you've been warned, lol)

Wow, I love the way you incorporated the seventh degree - instead of an extra inner ring, just converting that one to show a diminished chord. The extra rotation of the inner circle is really clever too. That is awesome, thanks for sharing!
