Hey HN We made a site that let's anyone measure the forever chemicals in their blood with the gold standard LC-MS/MS blood serum test at Quest Diagnostics. If you're a firefighter, plant worker, planning to become pregnant or just someone who lives in an area with contaminated drinking water, check it out. I live in Santa Cruz. Here are my results: My lab findings: https://res.cloudinary.com/mpsh87/image/upload/v1687923285/l... My total PFAS calculation: https://res.cloudinary.com/mpsh87/image/upload/v1687923482/p...…

I'm from a compost tech startup (Monty Compost Co.) focused on making composting more efficient for households and industrial facilities. But our tech isn’t just for composting— it’s a versatile system that can be repurposed for a wide range of applications. So, we’ve made it open source for anyone to experiment with! One of the exciting things about our open-source compost monitoring tech is its flexibility. You can connect it to platforms like Raspberry Pi, Arduino, or other single-board computers to expand its capabilities or integrate it into your own projects. Our system includes…

Nutri is still in beta and the GPT-powered results are sometimes inaccurate. The nutrient information accuracy is good to get an overview, but there are still outliers at times. I'm looking to improve the accuracy through food databases. Furthermore, I'd like to add additional tips for combining / preparing food to improve its nutritional value. For example, iron absorption is improved through vitamin C, so combine chickpeas or leafy greens with lemon. Or combine beans with rice to get all amino acids. On the UX side, I'd like to integrate a QR code on the desktop version to easily…

Composting is a great way to reduce waste and nourish your garden, but it can be confusing to know what items can and can't be composted. That's why I created canicompostit.com - a simple and fast way to find out. With Can I Compost It?, you can quickly search for any item and get a simple "Yes" or "No" answer, along with some tips on how to compost it properly. My real-time database is constantly updated with new items (and if you search for something and it's not in it, you can suggest it, then I research the item and add it to the DB). I included compost categories (brown or green) and…

https://blendful.com Hi everyone. I'm a technical founder who's built a MVP of a crowdfunding product intended to fund spectroanalysis testing on popular foods for contaminants, pesticides, herbicides, etc. Right now food products are a sort of black box, and consumers don't really know what they're getting. I'm looking to elucidate those details. Warmly looking for feedback and/or ideas if you find this useful. Also would be interested in partnerships/cofounders (biz dev/marketing help especially). Thanks so much for reading!

I’ve been working on xPlant, a dashboard for managing plant tissue culture projects. It’s designed like a “GitHub for plants” — you can track growth, experiment with different media, and iterate on your cultures over time, similar to versioning code. The goal is to give hobbyists, researchers, and growers a tool to see what works, optimize conditions, and learn from past experiments. I’d love feedback from anyone who experiments with plants or cares about reproducible growth data.

A little while back I posted a little experiment we ran linking plants to the web in the garden. Well we got a lot of positive feedback on that idea, and decided to launch https://www.knownplants.com. It's a web application paired with fairly inexpensive semi-smart NFC enabled labels that help gardeners keep up with their plants. What do you think?

I'm 17 and recently launched a private beta for Biohack - a tool that scans food products and gives a longevity score based on impact on aging factors such as inflammation, omega ratio, toxins and more. Still early and a bit rough, but I'm looking for honest feedback from people who care about health span and deep nutrition. Would love your thoughts.
