Working on fabric construction blocks (like Lego of clothing), that you can use to build clothing and accessories completely by hand without any tools or machines. Intro video: https://www.youtube.com/watch?v=X_eKc6c5tDw

ah this is fascinating!!!! Any more info anywhere?

Here's a recent interview: https://www.youtube.com/watch?v=85fy8cXpkyk

Also, I've been working on this for a while under a beta version called Self-Assembly, which was a bit more fashion oriented. New i-t-s-e rebranding is to be more Lego like. Here's the old website: www.self-assembly.fi

Clever seams. Have you tried washing any of the garments?

Yeah, I've been wearing and washing the prototypes for years now.

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…

Surface level thinking, ecological disaster in the making. Birds and bats and other bugs eat mosquitoes to live. Killing all the mosquitoes is like the Chinese killing all the sparrows. We do not understand, and we do not want to understand, the deep consequences of our actions. People who think we can reengineer and shape ecology by eliminating key species are here on the dunning Kruger curve. Better option, if you…

In general I agree that messing with ecosystems sometimes has unpredictable consequences.

In the case of mosquitos, though, they cause so much suffering, that it would be stupid to not work on eradicating them because of possible negative consequences.

We have to be careful, of course (widespread use of insecticides is a problem), but targeted measures are really unlikely to cause more harm than mosquitos already do.

Brilliant work! Zippers got nothing on this! I am particularly taken by how the "stich" weaves into itself, to flatten the seam. Now, what about footwear, I'm thinking. Stitched soles + uppers are so much more durable. If you could cut a sole to a person's foot size, then they could construct the upper to their best-fit, best-colour-combo design.

I've tried some footwear! These had a really soft rubber soles, but I've also made ones where the soles were cut from a sheet of hard Vibram rubber: https://self-assembly.fi/canvas-shoes

We recently installed a solar system on the roof, battery included. The app it comes with is okay to answer most questions. But that wont prevent me from shipping my own dashboard based on locally scraped data. Just for the sake of it. Also my homelab machine is bored.

fully custom made? Or Grafana?

I recently launched one of my small side projects. It's quick online multiple choice code tests aimed at recruiters to evaluate applicants: https://hashtagcode.io

The goal was to make a simple way for recruiters to create coding tests to screen people applying for jobs, and to make the process quick and easy for applicants. The default is a 15 minute multiple choice test across a few different domains.

I will eventually monetise it (when I have more free time) but for now it's free (1000 invites) so I can get feedback and improve it

I'm working on a development tool for specification-driven development. It uses LLMs to verify that your specification files and implementation do not drift. More specifically, I am trying to lower the number of false positives I'm currently seeing. I find that the LLM will hallucinate issues when there are no discrepancies, or become forgetful in the case of long documents (like RFC texts). The first step in improvi…

How does this compare to previous generations of specification-driven development using formal methods?

Been working on a real time public transit app for the Bay Area and New York but recently decided to use the same data to create a visualization of all the transit vehicles moving in real time!

Initially wanted to make this before my app but it was quite a bit to process all the GTFS data. But now that the data is already processed for the app, the visualization was quite easy to make!

Currently trying to add geocoding so users can search for destinations for routing. Been interesting as I want to avoid Google Maps and other private data sources so open street maps it is.

Working on an open source RAG-as-a-service platform that bakes in the best practices and continues to evolve them so that customers get the best retrieval without having to go deep or stay up to date.

Our flagship feature is Agentic RAG, which is quite difficult to build from scratch.
