Show HN: AboutIdeasNow – search /about, /ideas, /now pages of 7k+ personal sites
Hi HN!<p>It’s hard to find interesting people to work with on your ideas.<p>Our solution: index the /about, /ideas, /now pages of 1000s of personal websites. There are thousands of cool personal sites out there, with amazing ideas on them, but there’s nowhere to easily search through. So we built a simple site that indexes 7k+ personal sites [0]. We were inspired by Derek Sivers’ Now page movement [1] and other IndieWeb directories [2], but we figured that it would be more useful if we:<p>* Let you search directly across personal sites without having to visit them<p>* Take the content from 3 specific pages, /about, /now and /ideas, to structure everything<p>* Define /ideas pages as a space to articulate things you want to work on<p>We hope this’ll be a cool place for people to find others to collaborate with - would love your feedback. If you’d like your site to appear at the top, add it via the form and add a last updated date of today (any format). It’s completely open source (MIT) and open to contributions [3]!<p>Peter & Louis<p>[0] gathered from: 1) <a href="https://nownownow.com" rel="nofollow">https://nownownow.com</a> and similar sites 2) checking all HN posts since 2020 with more than 100 upvotes<p>[1] <a href="https://nownownow.com" rel="nofollow">https://nownownow.com</a><p>[2] <a href="https://personalsit.es" rel="nofollow">https://personalsit.es</a><p>[3] <a href="https://github.com/lindylearn/aboutideasnow">https://github.com/lindylearn/aboutideasnow</a>

Show HN: Reverse-Engineering a Switch Lite with 1,917 wires
Hey Hackers. This is a project I solo-developed that turns completed PCB assemblies into an easy to use boardview with some accompanying boardscans. There are lots of easier and better ways of doing this, but this is an experimentation to do it as cheaply as possible, with the highest quality and lowest chance of errors. The technical details are in the link.<p>Most public boardviews are almost entirely the result of industrial espionage, other than a few encrypted subscription based software platforms that provide extensive access. The process output is released as donationware, as my main concern is that even released as a low-cost purchase, there is a very strong culture to share this type of information at no cost. I would like to have a more sophisticated suggested donation system adaptive to user country, but I wasn't able to find a good solution.<p>In terms of 'good startup ideas', I don't think this is one of them. The very high level of soldering skill required makes it difficult to scale, and the prevailing piracy culture makes it challenging to monetize. My main advantage is that costs are very low now that I have the entire thing working. Other than forge ahead at a loss and hope for the best, or to pivot hard leveraging the imaging technology, I'm not sure what other options I have. It feels too complicated and repetitive for shoft-form video content. If you have any feedback, questions, suggestions, etc., I'd love to hear them.

Show HN: OK-Robot: open, modular home robot framework for pick-and-drop anywhere
Hi all, excited to share our latest work, OK-Robot, which is an open and modular framework to perform navigation and manipulation with a robot assistant in practically any homes without having to teach the robot anything new! You can simply unbox the target robot, install OK-Robot, give it a "scan" (think a 60 second iPhone video), and start asking the robot to move arbitrary things from A to B. We already tested it out in 10 home environments in New York city, and one environment each in Pittsburgh and Fremont.<p>We based everything off of the current best machine learning models, and so things don't quite work perfectly all the time, so we are hoping to build it together with the community! Our code is open: <a href="https://github.com/ok-robot/ok-robot">https://github.com/ok-robot/ok-robot</a> and we have a Discord server for discussion and support: <a href="https://discord.gg/wzzZJxqKYC" rel="nofollow">https://discord.gg/wzzZJxqKYC</a> If you are curious what works and what doesn't work, take a quick look at <a href="https://ok-robot.github.io/#analysis" rel="nofollow">https://ok-robot.github.io/#analysis</a> or read our paper for a detailed analysis: <a href="https://arxiv.org/abs/2401.12202" rel="nofollow">https://arxiv.org/abs/2401.12202</a><p>P.S.: while the code is open the project unfortunately isn't fully open source since one of our dependencies, AnyGrasp, has a closed-source, educational license. Apologize in advance, but we used it since that was the best grasping model we could have access to!<p>Would love to hear more thoughts and feedback on this project!

Show HN: Pages CMS – A CMS for GitHub
In a nutshell:<p>1. You log in with your GitHub account.<p>2. You select the GitHub repo where your site/app is at (whether it's Next.js, 11ty, Hugo, Nuxt... as long as you're using flat files for content).<p>3. You add a single config file to your repo to define the content types and other settings (e.g. media folder).<p>4. Congrats: you now have a user friendly CMS to manage content + media BUT all changes are still tracked like regular commits (under your account) on GitHub.<p>I started using Jekyll around 2009 and over the course of the past 10+ years, I've helped build major sites and tiny blogs with Hugo, Gatsby, Next.js and more recently 11ty.<p>I still love it.<p>BUT once you're done building, managing content and media can be a bit of a pain. You have a few options:<p>- Edit files directly (on GitHub or your local). Good luck getting your colleagues on the marketing team to do that.<p>- Hook up a headless CMS like Contentful, Sanity, or Strapi. That works, but it's one more dependency and (IMHO) overkill in most cases.<p>- OR you could use something like [Decap CMS](<a href="https://decapcms.org/" rel="nofollow">https://decapcms.org/</a>). Really cool project, but I've never been a fan of the UI/UX, and it's been a bit of a pain to setup (maybe that's just me).<p>I wanted something as simple as possible, preferably with nothing to install or deploy.<p>Back in 2018, I had built a prototype (Jekyll+) [1] with the idea of getting a CMS set up by just adding a single configuration file to your GitHub repository.<p>Pages CMS [2] is a continuation of that idea. It's 100% free and Open Source: <a href="https://github.com/pages-cms/pages-cms">https://github.com/pages-cms/pages-cms</a>.<p>If you don't want to use the online version because you're not comfortable signing up with your GitHub account, consider the following options:<p>- Use a fine-grained personal access token [3], there's an option on the login screen. There is still a bug if you try to access a repo that isn't part of your token scope, but I'll get it fixed in the next couple of days.<p>- Deploy it yourself (for free) on Cloudflare Pages. Literally 5 minutes of work max. I made a video walking you through the process [4].<p>- Check out the intro video on the front page [2] (a bit crap, but I'll get a better one up in the next few days).<p>I use it actively with a few other teams, I hope it will be of use to some of you.<p>I'm already working on adding a few nicer features, like collaborative editing and email invites (to let non-developers login without a GitHub account).<p>PS: I've spent the past 8+ years building a business and only recently got back into coding. I'd love pointers as to what I could do better (and how I can manage my Powerpoint PTSD).<p>[1]: <a href="https://github.com/hunvreus/jekyllplus/">https://github.com/hunvreus/jekyllplus/</a><p>[2]: <a href="https://pagescms.org" rel="nofollow">https://pagescms.org</a><p>[3]: <a href="https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#fine-grained-personal-access-tokens" rel="nofollow">https://docs.github.com/en/authentication/keeping-your-accou...</a><p>[4]: <a href="https://pagescms.org/docs/development/" rel="nofollow">https://pagescms.org/docs/development/</a>

Show HN: PRQL in PostgreSQL
This extension let's you write PRQL functions in PostgreSQL.<p>When I first saw PRQL on Hacker News a few months ago, I was immediately captivated by the idea, yet equally disappointed that there was no integration for PostgreSQL. Having previous experience with writing PostgreSQL extensions in C, I thought this was a great opportunity to try out the pgrx framework and decided to integrate PRQL with PostgreSQL myself.<p>The maintainers of both PRQL and pgrx were very nice to work with. Thanks guys.
