Currently a one-man side project: https://laboratory.love

Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard.

That seemed solvable.

Laboratory.love lets you crowdfund independent lab testing of the specific products you actually buy. Think Consumer Reports × Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid’s snacks, or whatever you’re curious about.

Find a product (or suggest one), contribute to its testing fund, and get full lab results when testing completes. If a product doesn’t reach its goal within 365 days, you’re automatically refunded. All results are published publicly.

We use the same ISO 17025-accredited methodology as PlasticList.org, testing three separate production lots per product and detecting down to parts-per-billion. The entire protocol is open.

Since last month’s “What are you working on?” post:

- 4 more products have been fully funded (now 10 total!)

- That’s 30 individual samples (we do triplicate testing on different batches) and 60 total chemical panels (two separate tests for each sample, BPA/BPS/BPF and phthalates)

- 6 results published, 4 in progress

The goal is simple: make supply chains transparent enough that cleaner ones win. When consumers have real data, markets shift.

Browse funded tests, propose your own, or just follow along: https://laboratory.love

We're building a repairable and more sustainable ebike battery at https://infinite-battery.com :)

Any chance you'll take a look at power tools next?

There are some Amish people who rebuild Dewalt, Milwaukee etc battery packs. I'd like a repairable/sustainable platform where I can actually check the health of the battery packs and replace worn out cells as needed.

To give you an idea of the market, original batteries are about $149, and their knockoffs are around $100.

I am working on Magnetron ( https://magnetron.ai ) It is a tool that lets you create whiteboard explainers. You can prompt it with an idea or upload a document and it will create a video with illustrations and voiceover. All the design and animations are done by using AI apis, you dont need any design skills. Here is a video explainer of the popular "Attention is all you need" paper. https://www.youtube.com/watch?v=7…

I really like the idea! One issue though is that the content seems to "stream" much slower than what's being spoken. The result is that I'm sitting there waiting to see whats going to come, even though its already been said which makes it hard to focus on whatever new information is coming.

The animations / drawings themselves are solid too. I think there's more to play with wrt the dimensions and space of the background. It would be nice to see it zoom in and out for example.

I'm currently working on building a local delivery service using electric cargo bikes in NYC: https://hudsonshipping.co. We are planning to launch our first pilot in early 2026 with our first customers in Brooklyn. We've built all of the tech in-house to manage the fleet, deliveries and optimize our routes. If you know of anyone that would like to be a part of the pilot program, feel free to reach out to me!

Are you planning to turn this into a full-fledged CRM of some sort? Are you planning to add user login with templates/company fields auto-populated at one point? Looks very clean, congrats.

Thanks! Appreciate it. No plans for that at the moment - I mainly built it for my own use =)

I wonder if you could just send invoices to Comcast for price increases to their Payable Accounts department and if they'd just pay them. Or just invoice companies for "inconvenience fees" of sorts when they actually create inconveniences.
