A few people have reached out over the past months asking what happened to [h1Disclosed] https://x.com/h1disclosed, the bot that automatically shared newly disclosed HackerOne reports.

The short version is that when X/Twitter moved to its paid API model and usage-based pricing, the original implementation became impractical to operate. As a result, the bot eventually stopped posting and went offline.

Over the last few days, I spent some time rewriting parts of the infrastructure and building a custom workaround to get things running again without relying on the previous setup.

The good news is that disclosed reports are being posted again.

The bad news is that X is still restricting access to one of the endpoints I migrated to for this workaround(X wants me to pay for it :/), and working around that will require a more complex solution that I'll continue working on over the coming days.

Until that is fully resolved, report updates are temporarily being posted through my personal account: https://x.com/rynosec

If you were following x.com/h1disclosed for disclosed HackerOne reports, feel free to follow along there for now. Once I've finished the remaining workarounds, I'll evaluate the best long-term approach for bringing the project back to its original form.

Thanks to everyone who reached out and asked about the project. It's been fun dusting it off and getting it back online.

A few days ago I had this random idea: what if I used the Flipper Zero as the UI/brain for a tiny offline music player, and let an external MP3 module handle the actual decoding/audio output?

I ended up building it.

The project is called Flipper Walkman:
https://github.com/rynosec/flipper-walkman

What it is: -
a native Flipper Zero external app (.fap)
- retro cassette / Walkman-style UI
- controls a cheap UART MP3 module over GPIO/UART
- MP3 files live on the module s microSD card
- audio comes out from the external module, not the Flipper itself

Current controls:
- OK = play/pause
- Left/Right = previous/next track
- Up/Down = volume up/down
- Long OK = About/Help
- Long Back = exit

Hardware I used:
- Flipper Zero
- UART MP3 module (GD3300D / HW-311 / YX5300-style board)
- microSD card
- headphones/speaker connected to the MP3 module

A couple of notes:
- this is not native MP3 playback on Flipper
- the Flipper is basically acting as the controller + UI
- the MP3 module handles file storage, MP3 decoding, and audio output
- song names are not displayed yet because these cheap UART MP3 modules usually don t expose filenames or ID3 metadata nicely over UART

I wrote a full build write-up here too: https://ryno.sh/posts/building-a-walkman-style-mp3-player-on-flipper-zero/

This started as a fun nostalgia project more than anything serious.

Would love feedback from the community:
- Has anyone else built something similar?
- Any better MP3/audio modules I should try?
- Any ideas for improving track naming / metadata UX?
- Would people want playlist mapping from Flipper SD card in a future version?

I am also working on doing a proper plug and play solution with custom 3D printed case, let me know what you feel about this project.

This is my current setup after a recent cleanup and rearrangement.

One thing I've been struggling with is that before this, I spent years working from a tiny ~90cm desk tucked away in a corner. It wasn't fancy at all, but it felt incredibly cozy and I could sit for hours without thinking about the setup itself.

A few years ago I upgraded to this custom L-shaped desk(180x60x75cm, L part-120x50x75cm) because I wanted more space and a cleaner-looking setup. While I like how it looks in photos and the amount of room it gives me, sometimes it feels too large and open compared to that old corner-desk feeling.

I've been experimenting with monitor positions, moving things around, and trying to make the space feel more inviting again.

I'm debating whether to keep improving this setup or sell the desk and eventually move to a sit-stand desk. My biggest hesitation is that this desk is custom-made, very sturdy, and built from quality materials, whereas most sit-stand desks in my budget seem to use particle board and may not last as long.

What would you do in my position?

• Keep and improve this setup?
• Modify the desk somehow?
• Sell it and move to a sit-stand desk?

Also, what feels missing here? Any suggestions to make it feel more cozy, personal, and fun to spend time at?

I've been tweaking this setup for a while and I'm a bit conflicted.

This custom L-shaped desk(180x60x75cm, L part-120x50x75cm) gives me a lot more space and looks much better aesthetically, but sometimes it feels too big and open.

Lately I've even started sitting on the extreme right side instead of the center, using the side monitor and PC almost like walls, just to recreate that cozy corner feeling I had before.

I've been building PCs and tinkering with homelab servers for quite a few years now, and it's become one of my favorite hobbies. One of the machines in my homelab currently powers a 24/7 ad-free nostalgic Bollywood radio station that streams songs from the 2000s and early 2010s.

The setup is fairly straightforward - Nginx, Icecast, and some automation scripts, but it has taught me a lot about self-hosting, monitoring, uptime, backups, and maintaining a service that runs continuously.

The same server also hosts several other side projects and bots, hope you guys might like it. Looking forward to your feedback on this ;)
