1. Show HN: Apple II clock using interrupts from physical pendulum clock
URL: https://github.com/wkjagt/apple2_pendulum_clock/blob/main/README.md
Author: wkjagt
Description: A clock app for my Apple ][ clone in 6502 assembly, using interrupts generated by an inductive proximity sensor and a physical pendulum clock. I wanted to polish the code a bit more before sharing (I especially dislike the self modifying code part), but the computer seems to have developed a hardware problem lately and it keeps crashing (bad RAM chip most likely), so I am sharing as is.

3. Show HN: 12-colored visual interactive music theory for pop/rock MIDI (+Github)
URL: https://rawl.rocks/
Author: vitaly-pavlenko
Description: I'm sharing an early prototype of my open-source interactive book and MIDI viewer. My approach is to annotate a tonic and phrasing in each file, so that chords become visible as 3-4 color bundles after a bit of training. This radically simplifies seeing and hearing chords, so that you can rapidly browse through many arrangements and study Western harmonic/arrangement language
If you don't have a touchpad, a horizontal scrolling can be done via shift+mouse wheel (generally on the web). Also, I have a second color scheme that I tried to optimized for people with color vision deficiencies.
My big dream now is to have all piano rolls in DAWs support 12-coloring (in any color scheme really), so that the music can be seen as less complex, less gatekeeped and less entangled. It's not as hard as I've seen it before.
Source code: https://github.com/vpavlenko/rawl
It currently doesn't play music from Russia or Türkiye (=requires a VPN), because I rely on corsproxy.io internally which blocks access from those countries. I plan to rehost stuff on S3 soon to fix that.
Also, it's more performant in Chrome than in Safari - audio clicks less.
===
Backstory: I quit Whatsapp in 2021 to focus full-time on studying music theory. Along that I've assembled a list of resources to see the frontier: https://github.com/vpavlenko/study-music
My biggest inspiration is Hooktheory - an interactive book that teaches how melody and chords interact in Western pop music. After it I wanted to study how the rest of the arrangement works - what the bass line is doing, how is melody doubled, what chromatic chords are possible, are there any functional pre-dominants and dominants in mixolydian or dorian etc.
I wanted to focus on music for which the complete arrangement is clean and available. This is early chiptune (NES/Genesis) OSTs and MIDI arrangements (primarily created in 1990s). As I plugged MIDIs into my front-end, I discovered that the harmonic analysis - the cornerstone of studying Western harmony - can be done by eyes in real-time. That is, if you color the notes consistently, the chords start to stare at you, sharply and memorably.
I'm intrigued by latest shifts towards corpus studies in music theory and I'm generally happy that nowadays the research is not just about classical music anymore. At least in the West.

4. Show HN: I made a mobile app and game where you workout to level up
URL: https://www.fittestfire.com/
Author: David_FF
Description: Hi, I’ve been working on a workout logging mobile app and game to motivate myself to workout called Fittest Fire.
Logging workouts in the mobile app gives you points which are used in the game to increase damage, health, speed, etc.
The mobile apps are native Kotlin / Swift and have been released. The game is currently in demo status but has the level up system in place.
You can easily skip the account creation process for the mobile apps and play around with it first. In that case, you can only save exercises locally. If you have an account, you can save exercises online and get points. Everything is currently free to try (as in beer)

7. Show HN: Hacker News AI built using function calling
URL: #
Author: bediashpreet
Description: Hi HN, I built an AI that can interact with the Hacker News API and answer questions about hackernews stories, whats trending, what on show etc..
Check it out here: https://hn.aidev.run
You can ask questions like:
- What's on hackernews about AI?
- What's on hackernews about iPhone?
- What's trending on hackernews?
- What are users showing on hackernews?
- What are users asking on hackernews?
- Summarize this story: https://news.ycombinator.com/item?id=39156778
- Tell me about the user pg
It uses function calling to query the HN api.
To answer questions about a particular topic, it’ll search its knowledge base (a vector db that is periodically updated with the “top stories”) and get details about those stories from the API.
This is pretty barebones and I built it today in < 2 hours, so it probably won’t meet your high standards. If you give it a try, I’d love your feedback on how I can improve it.
If you’re interested, I built this using phidata: https://github.com/phidatahq/phidata
Link to the HackerNews AI App: https://hn.aidev.run
Thanks for reading and would love to hear what you think.

20. Show HN: Techmart – Costco for SaaS. The usual tech tools at lower prices
URL: https://jointechmart.com/
Author: tarekabi
Description: So here’s the deal. I’ve been bootstrapping my startup and realised the sh*t ton that we’re spending on saas. You know the drill in this game, minimize overhead and maximise productivity, usually with tools. We use 28 SaaS tools today – apparently the average is 89, according to Okta - at a range of $9-$600 monthly; it adds up fast!!
That’s when it hit me! What if there was a Costco, but for tech tools?? Even software sellers would win, by acquiring customers at a lower CAC -- a no brainer for both buyers and sellers. So the concept is simple, a member store where you could buy all of your usual tech tools but at lower prices; Techmart.
I’ve built with my brother for the past 2 weeks and we’re now launching it to the world to see if we’re just crazy or this is for real. I’m curious, are we missing something or is it an untapped goldmine waiting to be discovered? Other people need this too? I'm ready to hear the harsh truth.

Then, with a custom publishing prompt, I had GPT-4 Turbo write a script for ElevenLabs, and posted it to a Slack channel.
