If someone wants to sponsor me I have ideas for this pay phone I saw at a Tennessee thrift store
Working on creating a demo visualisation of my Kubernetes cluster that runs in the browser. Just got network visualisation working. Each image is its own actual bit of running code using a fetch-like API to talk to other pods, and the network emits events when this happens.
I unironically love websites like this. No https, content straight to the point, loads in milliseconds, tiling background of cool rocks. This is peak.
I may have finally found the Python-in-a-sandbox solution I've been looking for... here's my latest experiment, this time running MicroPython in WebAssembly inside my Python applications simonwillison.net/2026/Jun/6/m...
Running Python code in a sandbox with MicroPython and WASM
I’ve been experimenting with different approaches to running code in a sandbox for several years now, but my latest attempt feels like it might finally have all of the characteristics …

You can just do things Like manually set the bytes being sent to a receipt printer
Fun fact: there are 11 unused pins in a parallel cord between the host and peripheral, mostly duplicate grounds
The cheap parallel to usb adapters I've bought aren't reliably working with my dot matrix receipt printer. Oh well, time to dive into the spec and wire a raspberry pi to communicate directly with the port instead!
Settling towards this design for my new forum, more "embrace tradition". What do you think?
Made a website that converts text to a 2-layer STL that I can make faux screen printing stencils with. There’s a pause between the layers where I sandwich in some tulle fabric.
I built an interactive guide on how Shazam (the music identification app) works! This is the next installment in my newly coined "How The Heck?" series, where we explore everyday tech that can feel like magic (QR Codes, GPS, and now this one). Hope you enjoy it! perthirtysix.com/how-the-heck...
I’ve been on a kick of collecting old recipe books, and I don’t think this sounds Italian or particularly delightful
My wife baked cookies for Easter and needed a specific half moon cookie cutter. I threw together a site that uses Three.js to design a parametric one and export the STL to be 3D printed. Custom cookie cutter in ~10 mins!
Take a Joy-Con and connect it with WebHID, draw a picture in the air and capture it with the sensors. Create an SVG path and insert in the DOM. Apply CSS styling. Sample the DOM and use WebUSB to convert to ILDA and send it to a laser projector. I created the worlds most complicated laserpointer…
This is a fully functioning Laravel application and playground rendered on a static Cloudflare page. The entire app is sandboxed to your client, all files are editable, and you can even run artisan commands.
I turned my old receipt printer into a ticker tape for stocks. Here's 2 hours of AMZN activity condensed down to 30 seconds:
Despite the overhype, there's a group of people building software right now who have never touched a line of code and don't care what their applications are written in. I kind of envy them, so I talked about it. www.youtube.com/watch?v=JEFx...
This software will never scale (and that's the point)

Both of these are running the same shared C codebase, isn’t that neat?
Little concept I tinkered with yesterday, trying to mimic the feel of a dice getting rolled. It's part of a larger project I'm still toying with, but I'll need a few more buttons!
I have random one-off ideas for apps, experiments, packages, etc. that normally I'd have to shove in a backlog for "someday". But the last couple of weeks I've tried just sloppin' out a working MVP and see if I want to continue with it. Most fun I've had in a very long time!
New home has one of these bad boys in it, thinking of repurposing it to use for Home Assistant commands. What do you think, y/n?
github.com/unhappychoice/gitlogue "Cinematic Git commit replay" this is so slick, I'll have to find a way to use this in some upcoming videos
