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. 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…

I built ChipBuilder to make computer architecture more approachable through interactive puzzles. You start with basic logic gates like AND, OR, and NOT, then gradually combine them into adders, multiplexers, memory, an ALU, and eventually a complete CPU. Once you've built the hardware, you can write assembly programs that run on the processor you created. The game is inspired by courses like Nand2Tetris, but everything runs directly in the browser with a visual circuit editor, simulations, and progressively harder challenges.

Inspired by games like Turing Complete/Virtual Circuit Board/Logic World, I tried to make a mix of aseprite and wiredworld/wired-logic, the idea being the user can build a digital circuit using a "fullstack" pixelart creation workflow. The circuit is just an image. The primitives are (i) connected wires which have undefined, 0 or 1 state during simulation (displayed brighter or darker in function of the state) and (ii) NANDs, which are little pixel triangles. During simulation the user can interact with any wire by clicking on it, toggling its state, which is cool for messing…

This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!

Hey HN! I’m Simone. We re-built Breadboard, a visual app builder that mixes Figma-style UI design with Shortcuts-style logic so you can build, preview, and publish interactive web apps directly from the canvas. What it does Design UIs visually with a flexible canvas –like Figma–. Define app logic with a visual, instruction-stacked editor inspired by Shortcuts. Live preview apps directly on the canvas –no separate preview window–. Publish working web apps with one click. Why we made it Modernize the HyperCard idea: combine layout, behavior, and instant sharing in one place. Reduce friction…

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.

Modo▲148I’ve built hardware projects for years, and the gap between “I want X” and “parts ordered, files ready to print” always took weeks. Modo compresses that. Describe what you want (e.g. “a portable CO2 monitor with a display and buzzer”) and it generates: - A bill of materials with real components (MPNs, not hallucinated parts) - A printable enclosure generated from actual part dimensions - Wiring diagrams, firmware boilerplate, and assembly instructions - Design validation (power budget, pin conflicts, mechanical fit) Everything streams in real time as each phase completes. The key idea is…

TL;DR - My cofounder Collin and I built an AI version of Digi-Key to help PCB designers find and use parts, except with a way bigger catalog, modern refinement tools, and an AI that can actually read the damn datasheets for you. *The problem* Modern circuit board design is filled with absurdly tedious tasks, where one small mistake can brick a project and cost thousands. The worst (in our opinion) is reading datasheets, which eats up to 25% of the first part of any project: 1. First, you slog through catalogs to find viable parts, using search tools that are still stuck in the dark ages.…
