Ask HN: What Are You Working On? (December 2025)

I got a couple new toys for birthday/xmas: the GPD MicroPC 2 UMPC and the M5Stack Cardputer.

The MicroPC is great because it makes it super easy to code and hack on something in places where it would be too awkward or annoying to whip out my laptop, and the Cardputer is just a fun little toy because it's so open ended and hackable. I've been writing an app for Cardputer to control my thermostat remotely, and I've had a lot of fun grossly overengineering the needless amount of concurrency I have added through FreeRTOS.

Something oddly satisfying about using a micro PC to program an "even more micro" PC. What a cool time to be alive; I would have killed for this kind of stuff as a teenager!

I built a universal live speech translating app.

I’ve been playing around with the Whisper models for a few years now. Last year I had an idea about how to run Whisper Large v3 in real time. That idea became ScribeAI.

Because the quality of transcripts was so high, much higher than I could get with Parakeet, I started to think about how it would serve as a good input for live translation. I played around with this and was surprised by how good the results is, I’ve used it to follow along political speech’s from foreign leaders and other content I’d have just never been able to consume before. You can translate by bringing your own LLM service API key or using the inbuilt Apple Translate models (for a completely offline experience).

https://fooqux.com/ - an experimental article aggregator about software development. For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website. The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc. I hope this service might be useful to others as well.

I’m working on Lunara AI: https://lunaraai.app

It’s a meditation app where an LLM guides you without the usual back-and-forth chat. You set your preferences up front (style, duration, focus), then it delivers a structured session end-to-end.

I have a long list of ideas and features to try, but right now I’m focused on feedback. The app is live on the App Store, and I’d love input on: • What would make you try an AI-guided meditation app (or avoid it)? • What settings matter most to you (duration, tone, technique, background audio, etc.)? • What would make the guidance feel trustworthy and not “chatty” or generic?

If you’re willing to test it, I’m especially interested in first-session impressions and what you’d change to make it something you’d actually keep using.

Slightly disappointed to realize there is not some automated drink machine behind this, as that's more my interest, but cool nonetheless and you handmade drinks are probably better.
