1-Bit Pixel Art Font Editor

I like making small fonts for Arduino and ESP32 projects with those little SSD1306 OLED screens. So I made this browser-based tool to help design pixel art fonts for use in those embedded projects. It has a preview area that updates when you save your character. It can support fixed-width and variable-width fonts. And when you're done you can export the font in a few different formats. It comes with a bunch of example fonts built-in. Also it's fully client-side code so you can save the webpage to use it offline. If you want some inspiration for fonts, I made a bunch of really small fonts a…

1-Bit Pixel Art Font Editor launched on October 7, 2025 with 6 votes and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

What it does

This tool is designed to help developers create fonts for embedded projects. Then use the glyph editor to draw glyphs. Click "Add/Update Glyph" to save them to the glyph library and update the preview. When the whole font looks good, use the export tool to get an array of byte codes in a format that fits into your project. Drag and drop the glyphs in the library to rearrange them so that the export comes out in the order you want. Font from elsewhere renders sideways: Try changing the Read Direction to "Horizontal" as some wider fonts are specified differently. The importer expect the input to be in the same format as the "C Style" exportfrom moonbench.xyz

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  • Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
