Launch HN: JITX (YC S18) – Automating Circuit Board Design https://ift.tt/2NYDbtR

Launch HN: JITX (YC S18) – Automating Circuit Board Design Hi HN, We're Duncan, Austin, Jonathan, and Patrick, the founders of JITX ( https://www.jitx.com ). Today, every circuit board is manually designed by skilled engineers. JITX is automating circuit board design with AI that designs optimized boards in hours instead of weeks. This all started for us while we were still at UC Berkeley. Duncan and Austin were PhD students and constantly designing robots to test new ideas. We realized we had to start from scratch every time we started work on a new robot. All that work had to be thrown away, because you can’t reuse hardware designs like software. We wanted a way to design robots faster; we wanted a way to design better robots! At the same time Patrick and Jonathan were building Chisel, an automated tool for digital logic design. The roboticists saw Chisel and got inspired. Patrick and Jonathan saw how people design circuit boards and were horrified. We hit it off and decided to solve the problem — we would make circuit board design more like software development: agile, flexible, reusable, fast. Our core technology is inspired by the technology used for designing computer chips. The introduction of Hardware Description Languages (HDLs, e.g. Verilog) in the 80s, revolutionized chip design. Instead of manually drawing the shapes that make up the circuit, engineers would instead express the intended behaviour of their circuit using code, and then have algorithms automatically translate that code into the necessary copper shapes. This workflow is what makes possible the billion-transistor chips we see today. We bring the same workflow to PCB design. Circuit board design is a multidisciplinary challenge, and we have to factor in electrical engineering (circuit design, RF design, signal and power integrity), mechanical engineering (thermal, vibration), and manufacturing (cost optimization, DFM/DFA/DFT). Unsurprisingly, almost every subproblem is computationally intractable, so we use clever representations and heuristics to arrive at good solutions. There are a million details to keep track of across all of those disciplines, and it’s high time we get computers to do the bookkeeping. To give you an idea of our workflow, here’s a link to the first demo we ever recorded: https://youtu.be/ra0SWTrLzhs . It’s rough and out of date (new demo here: https://youtu.be/lYrY7iskgng ), but it helped us get into YC and shows the key ideas. Cliff notes: we describe circuit boards with a domain specific programming language, and then compile that language into hardware designs (and simulations, and schematics, and documentation, and manufacturing outputs). You describe what you care about at a high level, and then the system solves for everything you don’t specify. For example, we request a board with BLE and a microphone, and the system selects matching key components from the library, solves for power supplies and component values, sources all the parts (thanks Octopart!), assigns pins, plans out placements, routes traces, and then exports a KiCAD project (board + schematic), and manufacturing outputs (BoM, Gerbers, etc.). If you care about the shape of the board, add it as a constraint; if you care about the position of a component, add it as a constraint; if you know which BLE chip you want, add it as a constraint. Design tools should be smart enough to solve for the million details you don’t care about, and optimize your design for what you do care about. We started JITX to give everyone ready access to professional-quality boards, and today JITX runs as an electronics design contractor. You tell us what a circuit board needs to do, we use our tools to design the board, fab it, and get it back to you. We already do this faster than humans can, and our speed depends on the design. For product and proof-of-concept boards, JITX is on average 3x faster and also cheaper than human contractors. Test fixtures and connector-based boards are almost fully automated, and we have already hit 24-hour turnaround times on designs. We’re not the first ones to think about better tools for circuit board design, but we are the first to use this approach. We know from experience that this is the way to go, and honestly we can't imagine a future where this tech doesn’t exist. We’re just racing to be the first ones to build it! - Duncan, Austin, Jonathan, Patrick PS: If you want to see the last robot we built before starting JITX, you can check out Salto here: https://www.youtube.com/watch?v=2dJmArHRn0U .

Launch HN: Toybox (YC S18)- Communicate changes to any site without writing code https://ift.tt/2mV2HEM

Launch HN: Toybox (YC S18)- Communicate changes to any site without writing code Hi HN! We're Jono and Brendan, the founders of Toybox (YC S18). Toybox lets designers, marketers, and copywriters communicate changes to developers on any website, without having to write code. These changes get annotated as CSS edits so engineers can understand, reply, and implement the fixes ( https://ift.tt/2K99Evv ). For years Jono and I have struggled to communicate changes with one another during the development cycle. As a UX designer and Jono as a full-stack engineer, we spend hours going back-and-forth, trying to make small but important tweaks to sites. This was by far the most frustrating part of our jobs, driving us to try to solve this age-old problem. While learning about the development to design handoff, we’ve come across some common challenges teams face. First, not all companies have sophisticated or easy to deploy staging environments to quickly share works-in-progress. Second, some designers make tweaks using Chrome Inspector, but these changes don’t persist and are recorded nowhere near the relevant web page. Lastly, the majority of these conversations are happening in unofficial and unformalized spaces, making it easy to dismiss and disregard. The first problem we attempted to solve was creating a way to share web pages without a staging environment. To do this, we built a chrome extension that collects and sends the rendered DOM of the current page to Toybox. People write HTML and CSS in creative ways, so making sure we accurately re-render the captured page within Toybox has consistently been a fun and difficult challenge (looking at you CSS in JS...). We built Toybox in a way that doesn’t require prior front-end knowledge to use. We created an inspector that makes any page feel like Squarespace—a universal WYSIWYG of sorts. As you make tweaks, those edits get saved as CSS allowing a developer to contextually review where on the page a change was requested and the relevant code required to resolve that change. To see it in action, we made a demo of Hacker News here: https://ift.tt/2LTNVg1 We're excited about the possibilities of having a rendered web page within Toybox. We’re currently testing the concept of style and component linting. Instead of the rules being tabs vs. spaces :) we can lint for incorrect uses of color, accessibility, typography, button styles, and so forth by using design files or style guides as inputs. With the rise of component libraries and design systems, we’re excited to further automate these QA efforts and make this communication channel even smarter. We’d love to hear your feedback and personal experiences when it comes to this phase of the development process. You can try Toybox for free here: https://ift.tt/2K99Evv Thanks, Brendan & Jono July 30, 2018 at 10:34PM

Show HN: Googling a sentence yields copycat sites and poor results in general https://ift.tt/2K1HthO

Show HN: Googling a sentence yields copycat sites and poor results in general Take the following sentence for example, searched in google with quotation marks included: "Booster seats, car seats and seat belts are equally effective at saving the lives of children" This is a sentence that originated (as far as I know) from here: https://ift.tt/2AjoQ9y... . The first page of results contains various websites that, on the surface, contain the quoted sentence but on closer inspection, contains the entire original content from montana.edu verbatim. Additionally, the first 5 results are from sciencedaily.com, with different titles for each result and were created (supposedly) over the past 10 years or so. Now if you go to the second page of results, the majority of results are now sciencedaily.com but by exploring the links, you find the phrase is embedded as a link to articles first shown as results on the first page of google search results. I thought this was interesting so I attempted to look up what might be another widely copied type of sentence across websites to see what other articles are copy and pasted everywhere, example from https://ift.tt/2mLDRam... : "The vaccine-autism debate has been going on for years. It has been a tale of shifting beliefs as child vaccination rates remain high" In this case, searching this sentence, quotes included, yielded results as before highlighting the sentence in almost every result that I found but the article itself was not copy and pasted verbatim as before. In any case, thought this might be interesting to share. Perhaps this show the futility or limitations of searching this type of content or it may also show how many websites are merely reposting noteworthy content in order to generate clicks or mislead people into thinking their website is legitimate when it comes to scientific data or studies.
