Show HN: A working 3D model of an Enigma machine
I watched the excellent Veritasium video [1] on the Enigma machine, and watched the full animation by Jared Owen [2], but was still a bit confused on how the inner mechanics of an Enigma machine work. I used Astra to build out the inner components through a combination of reference images, writing out hundreds of extremely detailed prompts, and building my own inspection tools to ensure that every part is sized and positioned in a historically accurate way.<p>It's still a work in progress, but would love any feedback on the experience so far!<p>1. <a href="https://www.youtube.com/watch?v=JsBZOcqZerk" rel="nofollow">https://www.youtube.com/watch?v=JsBZOcqZerk</a><p>2. <a href="https://www.youtube.com/watch?v=ybkkiGtJmkM" rel="nofollow">https://www.youtube.com/watch?v=ybkkiGtJmkM</a>
Show HN: JBR-001 – An open-source 3D printable desktop robot
We built a desktop companion robot that is powered by Arduino UNO Q. Project is open source: source code, 3D printable files and assembly instructions are available at Arduino Project Hub.<p>Robot is equipped with camera, distance sensor, buzzer, moves head and arms with 3 servo motors and has an animated display. It can recognise objects and respond to it. We build it with idea this should be fun project people can 3D print and build at home themself.

Show HN: NSL – WSL for Linux
One of the things that Windows really got right is WSL2. I drive an atomic Linux distro for daily use, but wanted a way to develop with multiple different distros with that same WSL UX. NSL is my answer. It is a faithful reproduction of the developer experience, powered by a single VM that hosts one or more systemd-nspawn containers with your development instances. Host file edits and port sharing come along for the ride, just like WSL. Take a look and tell me what you think... It's yet another step in my long journey to keep my host installation free from all the changing and breaking dev dependencies that force a reinstall every few months.

Show HN: PaperMono, e-ink fridge magnet shopping list with mobile web page
Fridge magnet shopping list on an M5Stack PaperMono (ESP32-S3, e-ink
touchscreen), synced with a phone web app over Wi-Fi. Works offline,
~2,400 lines of C++.<p>This is a great wee device! BLE, Wi-Fi and LoRa on one board makes it flexible
for way more than a shopping list, this is just what I built first. This
firmware only uses Wi-Fi.<p>Fully vibe-coded with Claude Code, I didn't hand-write this. I wanted to see
how Claude would get on with building something useful for a new hardware device.<p>As it's stuck to the fridge it's easy for the family to use, and it's already being used day to day which I'll admit is a first for a home built project like this
