Show HN: Purple Computer – Turn an old laptop into a calm first kids computer

Hacker News - Sun, 02/15/2026 - 8:39pm

Hey HN, I'm Tavi. I built this for my 4-year-old.

He and I used to "computer code" together in IPython: typing words to see emojis, mixing colors, making sounds. Eventually he wanted his own computer. So I took an old laptop and made him one.

That IPython session evolved into Explore mode, a REPL where kids type things and something always happens: "cat * 5" shows five cats, "red + blue" mixes colors like real paint, math gets dot visualizations. Then came Play mode (every key makes a sound and paints a color) and Doodle mode (write and paint). The whole machine boots straight into Purple. No desktop, no browser, no internet.

It felt different from "screen time." He'd use it for a while, then walk away on his own. No tantrum, no negotiation.

Some technical bits: it's a Python TUI (Textual in Alacritty) running on Ubuntu, so even very old laptops run it well. Keyboard input bypasses the terminal entirely via evdev for true key-down/key-up events, which lets me do sticky shift and double-tap capitals so kids don't have to hold two keys. Color mixing uses spectral reflectance curves so colors actually mix like paint (yellow + blue = green, not gray).

Show HN: ClaudeCraft – Minecraft server where Claude agents do everything

Hacker News - Sun, 02/15/2026 - 8:37pm

Hi everyone,

I created a Minecraft server where Claude agents do everything - you just watch and give commands. You can add new bots and ask them to do anything in the world. Users are just spectators, so all the tasks are executed by bots you create. It uses mineflayer and claude agent sdk under the hood to plan and execute tasks.

I used minecraft 1.21.11 java edition and you can add the server with the following address: claude-craft.com

Show HN: Crabify, a Spotify TUI

Hacker News - Sun, 02/15/2026 - 8:16pm

Hey HN,

I made a little Spotify TUI today because I was sick of the electron app draining my battery and otherwise slowing down my computer. I am using it right now and figured you all might find it useful.

Spotify doesn't seem to allow devs to create new apps at the moment, but this should work with any existing or unused app id.

Cheers!
