Show & Tell

A community for developers to share personal projects of any size or polish. Anything software/firmware/hardware.. ALL THE WARES!! Side projects, experiments, learning builds, half-finished ideas — all welcome.

Explain what you built, why you built it, and what you learned. Give feedback if you can. Ask for feedback if you want.

Rules

  1. Personal projects only (no company or paid product marketing)
  2. Include context: what it is, what tech you used, what you learned
  3. Be constructive and respectful
  4. No spam or referral farming
  5. Feedback is encouraged, not mandatory
  6. Mark NSFW content clearly
  7. If you see a project you like and you think is cool consider giving it a star!
AI Rules

Guys it's 2026, if you're not using AI at this point you're falling behind. That being said this community is not for showing off AI prompts that you put into gh Copilot or Claude or whatever, all that's showing the world is "hey I know how to make something up and explain it in 20 words while having the expectations of a team who gives a shit! Woow look at me!!".

So do your best to disclose where/how/why you used AI in your code, and if you suspect a project is entirely AI generated slop,, don't engage, don't bully, just let them eat their foot ¯\_(ツ)_/¯.

Icon and Banner were generated using ChatGPT, they're placeholders as of 1/20/26, will replace them with real art soon! https://chatgpt.com/share/696fa8bc-f3e0-8012-b6d7-350a8b53a0e1

I very much believe the world needs more DSLs for doing traditionally-point-and-click-adventure kind of operations in an easily auditable, reproducible, parameterized, precise, and programmatic way.

This is my first significant project in service of being the change I want to see in the world. (It's a few years old at this point, but I wanted to show/tell it anyway.) It's a DSL for making simple web comics and story boards.

This is a "scratch my own itch" kind of project. I was GM'ing a 5e game and I do my notes digitally. I have a system for managing my GM'ing notes in digital form that translates extended-syntax Markdown into HTML pages for me to reference at the table. (Yes I should open-source that as well, but I haven't gotten to it yet.) And my brain absorbs a story board way quicker than text. So I wrote codecomic and added some code to my GM notes system to let me just embed codecomic source code in the markdown such that it would render the comics to images and embed them in the HTML. That all took me from "ok, hold on everybody while I read the next paragraph of dense text about what's going down over the next 5 seconds of in-game time" to getting all the same information at a glance. (I still had bulleted lists of more reference information surrounding the story boards, but the story boards really improved the flow of the game.)

Go is my (no pun intended) go-to language for most things lately, and codecomic is written in Go. (I don't know quite what to call the codecomic program. "Interpreter"? "Runtime"? "Engine"? "Processor"? Maybe just "program".)

Dead Simple CI - looking for beta testers (deadsimpleci.sparrowhub.io)

Hey! I am building a brand new CI based on top of forgejo/gitea - the thing is to use general purpose programming languages instead of YAML for pipelines. So I have launched a forgejo instance with DSCI runner integrated, where you can find some example pipelines for demo projects - http://forgejo.sparrowhub.io/root

So I am looking for beta testers, anyone who wants to try out the dsci - please let me know - so I will create an account for you ( you may find the link to the discord channel at the web site ) and you will start to create and run pipelines for projects you like

I was working on another random side project and wanted to define configs like Pydantic-Settings without actually pulling in all of Pydantic into my project, so I started writing a custom config class which turned out generic enough that I could break it off into its own thing.

One of the main things I wanted is to be able to load a TOML file for settings but to also be able to override each config option with an env var. I also really like Pydantic's use of Annotation[..., ...] type-hinting so I did something similar

I don't really expect it to be used by anyone else but I'm excited about putting out my first PyPi package and figured I'd share it here :)

Any feedback is very welcome!

Also AI disclosure: I got AI to partially write the description but the code itself isn't written by AI

I bought this simple ass little macropad that uses real keyboard switches and for like a year I had no idea how to use it. There was no dirt simple file configed little command I can plant in my i3/config and be happy with it so I built it!

It was my first attempt at building a production-level thing out of rust and I'm really happy with it. Now I can finally use my goddamn macropad!!
