Ask HN: What are you working on? (October 2025)

Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics: https://circuitscript.net/. A basic IDE (called the Bench) to try Circuitscript is available online: https://bench.circuitscript.net/

Since the last month, I have created a complete schematic with Circuitscript, exported the netlist to pcbnew and designed the PCB. The boards have been produced and currently waiting for them to be delivered to verify that it works. Quite excited since this will be the first design ever produced with Circuitscript as the schematic capture tool!

The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.

The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so (because this is also part of the design process) and to encourage code reuse.

Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!

Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things.

Just added health inspection data from countries that have that in open datasets (UK and Denmark). If anyone know of others I'd be appreciative of hints.

Thinking of focusing on another idea for the rest of the year, have a rough idea for a map based ui to structure history by geofences or lat / lng points for small local museums

An implementation of statecharts. I'm working through core functionality using recursive algorithms.

I discovered that "least common ancestor" boils down to the intersection of 'root-path' sets, where you select the last item in the set as the 'first/least common ancestor'.

I have a lot of thoughts about this!

1. Radio is COOL. As a fellow ham I think you would agree with me on this one so I'll leave it at that.

2. Internet streaming gives you wider but far less localized audience. We will have an internet stream, but being radio first shifts the focus to local community and local content.

3. Internet streaming and radio have related but not entirely overlapping histories and contexts which impacts how people produce and consume their content. I love the traditional formats of radio and they are often completely missing in online radio which IMO models itself more often on mixtape and club DJ culture.

4. AI slop is ruining the world. I have this belief that as AI slop further conquers the internet we are going to get to a place where nobody trusts internet content. People will seek out novelty and authenticity (sort of how LLMs do lol) and I think there will be a return to local content and community.

5. Commercial radio sucks. The LPFM system is a wonderful opportunity to create a strong, community driven alternative to corporate media.

I built https://invoicepad.app which is a free, completely in-browser tool for creating invoices, estimates, and quotes. Yes, similar apps have been posted here before, but none were built the way I envisioned, so I made my own. The key difference: all invoice data is stored in the URL hash, not the querystring. This is important because querystrings are sent to the server with every request, while hashes stay local to your browser. This means I can never see your invoice data, unlike other similar apps. The workflow is simple: use your browser's bookmark manager as your invoice filing system. Or if you want to keep it offline, just copy and paste invoice URLs into a text document for storage. I’ve also included helpful features like saved profiles to save on repeated data input. The next step is to finish working on a browser extension (v1 is being tested) to make bookmarking, editing, and saving changes even easier, that is if I ever stop being distracted by other side projects.
