Three Kind Words – Spread kindness one mysterious postcard at a time
Ever wish you could anonymously drip-feed kindness through the mail? I tried answering that with Three Kind Words (https://threekindwords.com), a vending machine that sends three mysterious postcards over three weeks, slowly revealing a message. Here’s how it works: you pick a three-word message (like "You are awesome" or "I love you"), and each word is printed on its own postcard, mailed one week apart to your unsuspecting recipient. You stay anonymous until the final card arrives, completing the message and revealing who sent it. I made this because I love getting real mail and…

In the maker’s words, at launch
Ever wish you could anonymously drip-feed kindness through the mail? I tried answering that with Three Kind Words (https://threekindwords.com), a vending machine that sends three mysterious postcards over three weeks, slowly revealing a message. Here’s how it works: you pick a three-word message (like "You are awesome" or "I love you"), and each word is printed on its own postcard, mailed one week apart to your unsuspecting recipient. You stay anonymous until the final card arrives, completing the message and revealing who sent it. I made this because I love getting real mail and wanted a simple, meaningful way to help people feel more connected. Under the hood, it's built with Cloudflare Workers and a Hugo static frontend hosted on Cloudflare Pages. Payments are processed via Stripe, and postcard printing and delivery are handled through the PostGrid API. Each set of three postcards costs $5 total, postage included. I store only what's essential to fulfill orders (no addresses are shared or sold) and identifying information is wiped 60 days after an order is completed. Currently, it's available only in the US. I've received requests to expand internationally, but I'm still navigating the logistics, regulations, and costs involved. My first experience with Hacker News was unexpectedly wild: a blog post I wrote [0] hit the front page in February [1], but my app broke spectacularly due to a caching issue, right in the middle of my kid's birthday party. I wrote about the experience here [2]. Fortunately, everything's running smoothly now! I've processed over 200 postcards already, and seeing them reach people's hands has been incredibly rewarding. Huge thanks to everyone who's tried it and shared their feedback to help iron out early wrinkles. You can learn more about my progress here [3]. Two recent feature additions: - Mother's Day Button: Effortlessly send a thoughtful Mother's Day greeting with just a few clicks. We'll choose the right words, designs, and timing to ensure arrival by May 11th (don't forget!). - Display Name Override: Personalize your greeting with nicknames or custom salutations, while still using the recipient’s formal name for postal delivery. One of my goals with this project is learning how to grow something from nothing. I'd greatly appreciate insights on reaching potential customers, encouraging repeat visits, and spreading the word genuinely. I've started blogging, created a mailing list, and set up social media accounts with some basic SEO, but haven't ventured into paid ads yet. What's worked best for you when building an audience or gaining early traction for a product like this? As a thank-you to the HN community, here are five coupon codes for a free postcard set (one per person, please): GO0QPGCB ZSYWMLRL D2NYLIG4 77SN8PVC W2PWA831 If you redeem one, please comment below sharing your thoughts: what you liked, what could be improved, and which code you used. Check it out at https://threekindwords.com. Thanks for reading! I'm excited to hear your feedback! Stay gold. [0] https://threekindwords.com/blog/vending-machine-on-the-inter...

Here’s a free, fun, novel five-letter word game for the web! It’s a game I originally wrote for the iPhone in 2010, but wasn’t able to finish before my first child was born. When I left my senior web developer job in September 2021 I figured I would postpone looking for work and finish the game before another 11 years passed, and expose myself to new skills doing it (in this case, Swift). I released it on the App Store in December, then turned my attention to doing a web version — when suddenly Wordle was in The NY Times, and then everywhere. Perhaps foolishly, I plowed ahead and here we…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
