#642Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

Where can I find the link? Do I need to submit my email to see the "openly published results"?

#644Not as exciting or big as some of the projects on here, but just a small personal one I’ve been wanting to do for a while. I recently impulse bought an Epson receipt printer, and I’ve started putting together a server in Go to print a morning update every day. Getting it to print the weather, my calendar and todos, news headlines, HN front page. Basically everything I pick up my phone for in the morning, to be on pap…
Which printer did you buy? Only gave it a quick glance but there seems to be a wide variety of printers...

#645You area a Site Reliability Engineer and you get a page notifying your service is down and you rush to see your logs, metrics and other dashboards, start communicating in Slack and entering checking commands in a shell prompt.
In the same way pilots get put in emergency situations in flight simulators, I'm building an "SRE incident simulator" , a generalization of SadServers.

#646I'm building a budget app for my wife and myself.
Basic goals:
- Web based for zero update latency
- Have it work offline
- Automatically import transactions from my banks
- No running/hosting cost
- Secure
Tools used so far:
- InstantDB for the datastore, providing the offline capability too
- A gmail account that automatically gets forwarded bank alerts for purchases
- Gitlab.com w/scehduled pipelines for cron based email-syncing
- Netlify for the free hosting
- InstantDB magic codes / email links for securing the data
I'm at the point where I can track and categorize purchases, including split transactions.
Next steps:
- Add in date ranges for reporting / data views; e.g. show expenses incurred in a one month period instead of for all time.
- Add in planned / project transactions for month forecasting
- Statement import & import reconciliation and statement reconciliation
- Scrape company specific digital reciept emails (like Amazon) to autopopulate more transaction data
And that'll be the end of the stuff I can do for free. I think I will add features that require money and/or dedicated hardware though:
- OCRing receipts -> autopopulated transaction data / description
- Using chatgpt to suggest categorizations
- Scrape extra data from my bank sites, like physical addresses of entities involved in charges.

#647I'm putting the finishing touches on VT[0] - a minimal AI chat client focused on privacy. No tracking, clean interface, with support for deep research, web search grounding, tool calls, and RAG... and more.
The code is all open source on GitHub[1]. Really close to shipping now - hope to share launch details soon.
These monthly HN threads have been great motivation for me to keep building consistently. Thanks everyone!

#648I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy. https://github.com/scallyw4g/bonsai I also wrote a metaprogramming…
This is pretty cool!
I am also interested in game engine programming, but I am in the very beginning of the journey.
Do you have any recommendation on voxel engine learning materials (e.g. books, courses, etc)

#650Building an app that extracts key information from PDFs + highlights citations.
You provide a PDF and a JSON schema defining what to extract, and it returns the extracted values, the citations and their precise locations in the document.
This is especially valuable in workflows where verification of LLM extracted information is critical (e.g. legal and finance). It can handle complex layouts like multiple columns, tables and also scanned documents.
Planning to offer this both as an API and a self-hosted option for organizations with strict data privacy requirements.
