List stuff to borrow for your people, anonymously
Hey yall, I built this for my makerspace. We wanted to let each other borrow things, but also didn't want to put up a big shiny sign saying "hey everyone, my garage has a super fancy oscilloscope just sitting there" and also didn't want to necessarily always need to say yes to everything. However, when I show it to people, they've been suggesting using it for other things like board games, or wedding equipment, etc. I'm still trying to find PMF, so please let me know what you think! For the stack, it's all Elixir + LiveView which is really nice, and then Fly.io, Fly's MPG, Tigris Data,…
What it does
A shared shelf for people who already trust each other. You put up what you'd lend, anonymously. Tool sharing for the 21st Century.
They weren't hiding it, it just never came up. Now there's a place to post it anonymously, so someone can decide to support your group without being put on the spot. A pool is people who already trust each other , the ones you'd lend to and the ones who'd lend to you. Make one, or take the invite somebody already sent you. Send invites by email, or hand out the pool's invite link. There's a poster with a QR code on it, ready to print! Put up what you'd lend. Members see the listing without seeing whose it is, until you click Reveal in a chat for it. You see who's asking the whole time, with their profile, reviews and ranks . Someone asks to borrow it by opening a chat for your listing and…from toolpool.garden
In the maker’s words, at launch

I've built a thing! A few months back someone (not me) posted my Mac app Droplings to HN. It was incredibly rough around the edges back then, and in alpha. Well, it's finished now and sparkles like crazy. Please take a look! :)

This was more of a sandbox to play with Raphael and Flot than anything else but I think there are some interesting statistics in there. It'd be awesome to do this over time but I really don't have the spare time required.
- AUA user powered copy editing tool (running on Ars Technica)2011 · ▲56
I blew off a bunch of "serious" side work last month and built a tiny little embeddable editing tool that I've wanted to have for Ars Technica since, well, the beginning of internet time. It lets any random user make edit suggestions for writers/editors to consider and act on. I think it's pretty cool and it's gotten some good use over the last few weeks. Of note, it's uses a single-field signup form. Edit administration is currently email based, so all it needs is an email address to get people going. I'm sure I'm not the only person to ever do this, but I basically just turned it on one…

Everything that would be here is in the README. I hope this gets big, it has tons of potential.
- IBI built an open-source kernel for Texas Instruments calculators2014 · ▲20
You know that old TI calculator you used in high school, then put in a box and forgot about? Have you ever wished you had an operating system for your calculator with preemptive multitasking, dynamic memory management, a tree filesystem conforming to the FHS, and all the comforts of Unix? Well, good news: that's totally a thing that exists. I've been working on my kernel for about three and a half years now and I'm looking for new contributors to help out. It's written entirely in z80 assembly, and it's both challenging and fun to work on. There's an IRC channel for contributors or people…
- MHMy HomeLab (and other cool stuff)2024 · github.com · ▲9
Just wanted to make my first post about something interesting I've been working on for some time. Any ideas/suggestions for new hardware or software I should try out are welcome, though I will only have time for a major overhaul in a month or two where I want to redo and document everything a bit better than how it is currently. Hope this can inspire someone to start their own homelab or give some ideas to already existing ones!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
