   Diagram as code tool with draggable customizations▲266

   In the past I've used declarative diagram generation tools like Mermaid.js a lot for quickly drawing up things but for presentations or deliverables I find that I have to then move the generated diagrams over to a tool like Lucidchart which allows full control of the organization and customization. Therefore I am now working on this to combine the benefits of both into just one tool which can do both functions. The project is certainly in the early stages but if you find yourself making architecture diagrams I'd love to hear your thoughts on the idea or even a Github issue for a feature…

    React for Circuits▲197

    Hi HN! I've been working on a new way to build electronics/PCBs with Typescript/React, I'd love to know what you think!! I've wanted to program circuits for a long time- I started experimenting with the concept of creating circuits in React almost 8 years ago and have spent many weekends since to prove the concept. Over the past 2 months, I've decided to start working on tscircuit full-time.

    I made some transistor animations▲212

    Hi HN, I made some animations of the most important kinds of transistors using my semiconductor simulation, details of which are on the page. I tried to make the visuals as realistic as possible while also aiming for clarity. If you want to go beyond the charge carriers and look at, for example, the electric field, you can do so in the simulation software. The desktop software also has less common devices like IBGTs and SCRs that have similar animations. The last thread about my software was posted here about a year ago: https://news.ycombinator.com/item?id=43942279
