Claude Code Brought My Dead Projects Back to Life

The music modes app – this one used to be simple. It showed the musical modes and their chords. We could only hear a chord by clicking it. Now it does a lot more. Swapping the sound samples for the Web Audio API made it lighter. We can now play chords straight from our keyboard. There is also a key finder that works out a song's key from its chords, along with built-in progression examples the app can auto-play for us. A widget version is still in the works. Once it is ready, we will be able to embed the app on our own site, say to demonstrate a custom chord progression.

The transit fare calculator – the old version only cared about one thing: calculating the fare. Now it understands the network. It has a topology, so it can give transit information and estimates. It partially carries its own route data, scraped programmatically from KRL's official website. For quick access, there is a favorite route feature as well. And there is a new menu, Light Rail Transit, with a schedule pulled from LRT's official site.

The album artwork app – before, this app just searched for album artwork in HD. The API behind it was old. The results became not accurate enough. Updating the API makes the results better now. Along with the dynamic search placeholder based on what is trending in your country, I also added motion artwork. When a release has one, it will animate and we can download it.

The ice-breaking questions app – I actually had to take this one offline. When I stopped paying for the database service on Render, it went down. I moved it over to plain CSV instead. That lets it stand on its own again. It is simpler, though it means all the questions now sit exposed in my repository. I think that is okay, haha.

Entropy – a multi-purpose media converter tool. It was very straightforward. We choose a menu, pick our file, and it will be converted on our browser without sending it to a server. I added some improvement to the user experience. The conversion engine is around 31 MB, and it has to download before anything runs. That is a lot for smaller devices, so a confirmation step now appears before the process starts. The video compression feature also has its own guard. If the compressed file is projected to come out larger than the original, it stops before wasting our time (and bandwidth).

Updating app dependencies, swapping old APIs, adding a feature I always wanted. These used to be the chores I kept putting off. AI cleared what sat between me and the ideas. Time to create more.
