A large format XY scanning hyperspectral camera
A large format XY scanning hyperspectral camera launched on October 11, 2025 with 44 votes, #432 of 8,178 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
A large format XY scanning hyperspectral camera captures detailed spectral and spatial data across wide areas. The device combines hyperspectral imaging capabilities with XY scanning technology, enabling comprehensive analysis of materials and environments. It serves researchers, scientists, and professionals who need precise spectral information from larger surfaces. The system's large format design distinguishes it as suitable for applications requiring both high resolution and broad coverage.

From the sources
A hyperspectral camera captures spectral data for each pixel. To create a version of a hyperspectral camera I made use of a 200um fibre optic cable attached to a spectrometer which is moved in both the X and Y axis behind a large format camera lens. I make use of the https://www.colour-science.org library to create an RGB image from my spectral data. Note: I recommend watching ‘ Do It Yourself Hyperspectral ‘ for a much more sensible approach, which uses linear scanning, meaning a column of the image is scanned and a spectral graph for each row of the column is produced. Also see the links at the bottom of the page. I 3D printed a plastic bracket to connect the two stages…from anfractuosity.com

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
