Software for biomedical research labs.

Animal colony management is largely managed in Excel sheets, with no integrations to related systems or hardware sensing. We're working on the spreadsheet problem first, so that biomedical researchers can share information about their colonies with other researchers at their institutions, and explore the lines that other labs have. This opens up collaboration options and makes it much easier for the research community to find out what mouse lines other labs have (and may borrow for their own experiments).

Currently in closed beta at Harvard

Finally caved and built a custom AI newsletter curation platform for a friend who's been pestering me to automate his GPT news digests. Still no idea if there's real demand, but the learning experience with Cursor and Claude Code has been worth it. After growing my own newsletter to 800 subscribers, I'm convinced aggregation beats adding another newsletter to the pile.

Thanks to Claude, it works way better than I should've managed solo: https://www.procuratorai.com

Free signup to test: https://my.procuratorai.com/login (no help/intro yet, and I'm paying for tokens so not advertising it widely...)

Homepage is basically a one-shot Claude build using Nunjucks on Netlify (first time with both).

(Subscribe button is broken - still working on that...)

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

Please make sure it is specific to mosquitos and does not attack other insects. Insect populations worldwide are experiencing significant declines in both abundance and diversity, with several studies reporting reductions ranging from 40% to 75% over recent decades. Estimates suggest that 5%–10% of all insect species have disappeared in the last 150 years, and some global meta-analyses indicate terrestrial insect pop…

Don't want to underestimate how disastrous this could be for other insects. Even ignoring the impact on them, the impact on our needs to maintain pollinator populations.

I'm currently working on https://beontimer.com a free timing app for running and cycling races.

It started off because I wanted to see if I could print QR codes on a piece of paper and use these to detect people crossing a lap if finish line.

That proved more difficult than I thought, the QR codes were not easy to scan from far away and while moving. It is still in alpha stage.

What does work is a simple manual mode for people to use at their races.

I've been working on an encrypted environment variables management tool, called kiln[1], for teams. I know, tools like age and SOPS exist, but this partly came through because of the lack of a good UX around the encryption part especially for a team-based workflow. I aim to continue building kiln as a developer-first experience, making it seamless to integrate into a large team's workflows. The idea came to me when w…

Seems to be very cool project, especially for teams. I like Access control mechanism, and also klin run command is great!

Looks awesome! I'm using tailwind in my open source project and Ive been really struggling with accessible colors, inclusivecolors sounds like itll be perfect for me

> Ive been really struggling with accessible colors

Thanks, feel free to message me if you want some tips!

Most accessibility/WCAG guides say things like "Tip #1: Choose accessible colors", but they don't go into any detail about how you pick sets of colors that contrast, like text/background/border colors for buttons on different backgrounds, as if it's trivial. It's actually really tricky and can feel impossible in some scenarios until you internalize the basic rules and constraints.

I usually see people saying the opposite, that it's easy to pick accessible colors, when it's often not, especially when you have existing branding to stick to.

A multiplayer survival game based around voxel physics.

Can be described as Astroneer-like setting, Teardown voxel physics, in a Valheim-like online multiplayer survival game.

Game isn't really announced yet but I've shown some videos of the tech: https://x.com/Alientrap/status/1909316208563732866 (On Youtube: https://www.youtube.com/watch?v=ZWISaUmvit4 ) https://x.com/Alientrap/status/1918024969939808654

Among other things, I'm working on AOO, a cross-platform low-latency peer-to-peer audio streaming and messaging library: https://github.com/spacechild1/aoo

The C/C++ library can be easily embedded in host applications or plugins. It even runs on embedded devices, such as the ESP32. In addition, the project contains a Pure Data external and SuperCollider extension. There is also a third-party Max/MSP external: https://github.com/ddgg-el/aoo-for-max

For more background information, check out this article: https://www.soundingfuture.com/en/article/aoo-low-latency-pe... https://aoo.iem.sh/

The project is still in beta stage, but I hope to make a final release this summer.
