Ask HN: What Are You Working On? (July 2026)

I am working on a local first LLM frontend that saves all chats directly to your hard drive and ships in a single index.html file artifact that you can self host.

No code to show yet. I'm taking the time it requires.

This month I continue working on to refine my coding agent harness https://github.com/vinhnx/VTCode. Recently, I've added back Anthropic Claude Fable 5 and OpenAI GPT 5.6 models family (Sol, Luna, Terra). Fortunately, I've had support from the open source community and VT Code has advanced. I hope you give it a try.

Hi HN, still making progress on Circuitscript, a Python-inspired language for describing electronic schematics: https://circuitscript.net/. You can try it in the browser via the Bench IDE: https://bench.circuitscript.net/

The biggest addition in the past month is initial support for ngspice netlist export — you can now take a Circuitscript design and export it to a SPICE netlist for ngspice simulation. This is a step toward closing the loop between describing a circuit and verifying its behavior, all from the same source file.

I have also added bus support, which makes wide parallel connections like data/interface (I2C, SPI, etc.) lines much less tedious to connect up.

Recently I produced and tested a 161-LED charlieplexed array in Circuitscript, using nested for-loops to generate the array instead of copy-pasting every LED and connection by hand. I plan to write a blog post soon to document this design.

As always, the motivation is to describe schematics as code rather than by clicking around graphical CAD tools (KiCad, Allegro, Altium, etc.). I want to spend time on the design itself, with code expressing the intentions clearly and reviewable in text.

Feedback welcome, especially from anyone frustrated with graphical schematic tools! If you have a KiCad design you'd like to convert to Circuitscript, please reach out to me. I'm looking to test the limits of the language and happy to help with the conversion.

I'm working on a collection of networked games, around the central theme of a lockstep deterministic network model with 'delay frames' (between acting directly on user input and progressing actual shared network state).

You can try this here: https://locksteparcade.com/Client

Games included in the arcade, currently:

- Neon Swarm, a take on the classic lemmings game, with multiplayer versus and coop modes

- Serpents, a snake game (where you eat food, grow a tail and need to avoid this growing tail), with inertial movement and multiplayer

- Spirits, an homage to N++, where you work together to get someone to the exit, while avoiding enemies, figuring out how to open doors, and so on

- Pilots, a multiplayer asteroids battle with homing missiles

Each game solves the network delay problem (the problem of providing immediate feedback to user input and hiding the fact that actual changes to shared state are delayed) differently, and it has been very interesting to work through a bunch of different approaches to this.

If anyone else here is working on multiplayer network games, I'm very interested in setting up a regular "play each other's games" session.

The idea is that regularly playing with other game developers will help develop a kind of 'scene' (where you get a group of people together who make work in public but really aimed at each other, pushing and unblocking one another to become bolder and better at an accelerating rate, as described here: https://www.henrikkarlsson.xyz/p/scene-creation-engines ).

If you are interested, let me know!
