Pixelique
Online Arduino FastLED Simulator
What it does
Pixelique - browser-based Arduino FastLED editor and LED matrix simulator for developing animations before flashing real hardware. Write and edit FastLED code with syntax highlighting, preview effects in real time, and design custom LED layouts visually — from simple strips and matrices to complex SVG shapes. Save and organize your animations, experiment faster, and iterate without constant uploads to devices. Built specifically for FastLED workflows and smooth animations development.

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!
- IBI built an Free AI tool to generate pixel art from text descriptions2025 · pixelateimage.org · ▲21
Hi HN, I'm excited to share a project I've built: PixelateImage.org. Instead of being a traditional image editor, this is an *AI-powered tool that generates pixel art directly from your text prompts.* If you've ever wanted to create unique pixel art characters, scenes, or assets for games, art projects, or just for fun, but perhaps lacked the specific artistic skills or time, this might be for you. My goal was to make generating retro-style or modern pixel art more accessible. You can type in a description (e.g., "a brave knight in a dark forest," "a futuristic cityscape at night," "a cute…
- 1B1-Bit Pixel Art Font EditorOct 2025 · moonbench.xyz · ▲6
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…
Open-source pixel art editor with animation and auto-tiling tilesetsAug 2026 · simplepixelart.com · ▲8Hi HN! I built a free pixel art editor that runs entirely in the browser — no install, no signup, no watermark. The frontend is open source (MIT): https://github.com/comficker/simplepixelart What it does: - Sprite editor with layers, selections, mirror drawing, and an infinite-canvas workspace (multiple boards on one desk) - Frame-by-frame animation with onion skin, per-frame duration, GIF and spritesheet export - Tileset builder that auto-generates Wang-16 and blob-47 terrain sets from a single base tile — exports Godot 4 TileSet, Tiled .tsx, or PNG+JSON — plus a tilemap…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
