Switzerland. Block by block. At 1:1 scale

⭐ 140💬 53👤 theanonymousone

A Minecraft project recreates Switzerland at a true 1:1 scale, with each block representing one metre and terrain, glaciers, lakes, forests, and dams built from swisstopo open geodata. The Matterhorn and other landmarks are modeled to match real-world height and steepness. A free Jungfrau-Aletsch UNESCO area is available to test the setup, while the full country is offered as an early-access package.

Show HN: TitleArt – Make text like it's 1997

⭐ 255💬 39👤 davidbarker

TitleArt is a web-based text design tool that recreates late-1990s typography styles. It lets users edit text, fonts, colors, shadows, 3-D effects, motion, layers, and clip art, then export the result as PNG, SVG, GIF, or video.

PaperPilot – Zero-Cloud, Pure-Rust PDF Engine with WASM and MCP

⭐ 151💬 44👤 vardhan1237

PaperPilot is a PDF and document toolkit written in pure Rust that runs entirely locally — your files never leave your machine. A single engine powers an MCP server (letting Claude Desktop, Cursor, or any MCP client merge, split, OCR, and compress PDFs), a CLI, a browser-based WASM version, a Tauri desktop app, and a local REST API. Current features cover merging, splitting, rotating, compressing, pure-Rust OCR via PaddleOCR, watermarking, and PII scanning, with no Chromium or C++ runtime required.

Birdwatching rewires the brain and slows cognitive decline

⭐ 40💬 23👤 cisc

Birdwatching is increasingly used as a therapeutic activity for older adults and people with dementia, helping them feel more engaged, connected, and emotionally positive. New research suggests that regular birdwatching can reshape brain structure and activity in areas involved in attention and visual recognition, similar to learning a sport or musical instrument. These changes may help keep the brain more organized and slow age-related cognitive decline.

Dolly Parton's Imagination Library

⭐ 558💬 95👤 jumploops

Dolly Parton's Imagination Library is a book-giving program that sends free books to young children in several countries. The website provides information for parents, availability checks, donation options, and resources about the program and its partners.

Growing Trees

⭐ 74💬 9👤 ibobev

The article describes a procedural simulation for generating realistic tree shapes by modeling seasonal growth. Buds compete for light, with a growth resource allocated through the branching structure so well-lit buds produce new shoots while shaded branches are pruned. The method uses a voxel shadow grid or space colonization to estimate light and growth potential, producing emergent crown shapes.

Show HN: A Truly Modular Keyboard

⭐ 173💬 57👤 NotARoomba

Keybytes is an open-source modular keyboard where every key is its own 1u PCB with a CH32V003 RISC-V microcontroller, connected via pogo pins on all four sides so keys can be freely rearranged into any layout. A stacked STM32WB55 main board provides Bluetooth, USB-C, 2MB QSPI flash for key firmware, battery charging, and an RGB status LED. The case holds modules together with magnets, and the full design is shared in KiCad and Onshape.

Overgrown, when plants invade your abandoned tabs

⭐ 291💬 100👤 speckx

Overgrown is a Chrome extension that turns neglected browser tabs into overgrown digital jungles, with plants spreading from the edges as tabs sit unread. Once a tab is sufficiently covered, its content becomes inaccessible until the user drags a mouse to slash away the vines, using selectable tools like a machete, chainsaw, or flamethrower. The project is a playful creative experiment rather than a productivity tool, adding a fun obstacle to revisiting old tabs.

Superhuman Hardware Design Is the Easy Part

⭐ 23💬 8👤 gmays

Frontier AI models are rapidly approaching superhuman ability to generate engineering-grade hardware designs, including CAD, PCBs, and part sourcing. The core difficulty is the lossy interface between digital designs and physical reality, which complicates manufacturing, measurement, and iteration. As a result, even models that can one-shot electromechanical designs will still need extensive work to produce reliable physical hardware.
