Show HN: TurboGPT: train 22KiB transformer in 13s
Inspired by minGPT for home experiments.<p>Requires CUDA 13.4; build script is Windows only.
Show HN: Jevstiller – Distill Jev into a local model, with a disagreement bound
Show HN: Using 2D DFT, dithering, etc. to maximize eInk manga image quality
Kindle Comic Converter optimizes black & white (or color) comics and manga for E-ink ereaders like Kindle, Kobo, ReMarkable, and more. Pages display in fullscreen without margins, with proper fixed layout support. Output works great in KOReader.<p>Full details on what KCC does is in the readme with plenty of photos!<p>KCC has been under continuous development since 2012 and has code sign on both Windows and macOS. Also available on Linux.<p>-the current kcc dev
Show HN: Ledge.sh – Runnable Markdown Notes
Hi HN,<p>Ledge is a Markdown notebook that runs shell commands, code, SQL, etc from inside your own notes.<p>I built Ledge because I spend much of my day copy/pasting commands from my notes into the terminal. I was inspired by how much cmux helped me organize my terminals - but there was still a split brain between my notes and frequently run commands. I've been daily-driving it for the past few weeks and use it for deploys, API calls, smoke tests, etc.<p>Ledge runs your real shell just like a terminal app and can be hosted locally or remotely over SSH using ledge-server. I've been building it since July and have recently added support for all the major platforms: Mac (Silicon), Windows (WSL required), Linux, iOS, Android. Mobile devices require SSH access to a ledge-server and Android is still in beta and looking for beta testers (see link on website)!<p>It's built on Bun and Electrobun and is free and open-source. Feel free to review the code and contribute at <a href="https://github.com/ledgesh/ledge" rel="nofollow">https://github.com/ledgesh/ledge</a><p>Feedback is very much welcome. Any must-have features that are missing?
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: Pac-Bench – How well can models one-shot a Pac-Man game?
Benchmarks how well Harness+models can create a Pac-Man game from a single prompt:<p>“Create a Pac-Man game in a single HTML page”<p>Each model gets one shot — no follow-up prompts or fixes.

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
