If someone wants to sponsor me I have ideas for this pay phone I saw at a Tennessee thrift store

I unironically love websites like this. No https, content straight to the point, loads in milliseconds, tiling background of cool rocks. This is peak.
Render of a website dedicated to "ASCII - Binary Character Table" listing out the letter a-z with their ascii codes and binary bits. It has a tiling background of rocks.

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
A photo of a breadboard with the pins of a parallel cord split out and put in order in the board. A post it note with a crude drawing of the peripheral port and unused pins is next to it.

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?
Screenshot of a forum website called Andrew's Lab with different sections for General Chat, Projects and Builds, and more. The design is similar to mid-2000s era forums.

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’ve been on a kick of collecting old recipe books, and I don’t think this sounds Italian or particularly delightful
Recipe for Italian Delight: 1 lb package spaghetti, 1 lb ground round steak, 1 can corn, 1 can tomato soup, 1 cup oil, 1.5 cups grated cheese, 1 tsp Worcestershire sauce, 2 good sized onions, 2 green peppers, 2 cloves of garlic, finely chopped, 1 cup olives, cut fine. Salt to taste, bake 1 hour in a slow oven.

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!

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.

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 made a daily word game! This is sixhints, the goal is to guess a thing through a series of 6 clues that start ambiguous and get more specific as you go. If this is up your alley, play today's word and let me know what you think! 🔗 sixhints.com

I've released my first Go application! It's a (very basic) terminal video editor that uses ffmpeg and whisper to let you selectively choose which lines from a video you want to keep. You can also preview each line with a pop-up video player! It's called tsplice:

Completely forgot to mention it here, but I've hooked up my receipt printer to a public website through a Raspberry Pi and Cloudflare. You can send me a message, and it'll print out immediately on my desk! ping.aschmelyun.com

This single index.html page I threw together for a meme has been viewed almost a million times in the last week. Absolute insanity and I've loved every minute.

This weekend I built my own "autonomous coding agent" that works in the background and generates PRs when an issue gets added to one of my repos. Oh, and it's a single ~500 line long PHP file. Video coming soon!

A screenshot of 3 open windows: an IDE showing some PHP code, a terminal window showing a local PHP server running with debug information, and an open PR for "Fix for issue #33" in GitHub.

One of the biggest disappointments is the loss of detailed manuals for consumer products. Look at this manual for my Sony TV from 1972. That’s an entire exploded view of every component in the television along with individual part numbers (with pricing on the next page!)
