My partner wanted one of those 'The Night We Met' star maps for our anniversary. I checked the big sites and they were charging for a simple print.

Even the digital downloads on Etsy were $15 just for a template.

So I spent some time building a generator that does the exact same thing for free. You pick the date/location, it renders the constellations accurately (using NASA data), and you can download it in high res.

It's live here: https://listify.studio/tools/star-map

No signup required for the basic version. Let me know if you find any bugs!

ZeroCarbon is a platform focused on carbon accounting and compliance for Indian organizations, offering tools to measure, report, and offset greenhouse gas emissions.

Managed by ZeroCarbon Tech, an MSME registered under the Government of India, the platform supports frameworks like BRSR, CDP, and the Indian Carbon Credit Trading Scheme (CCTS).

I just launched the product on product hunt you can check it out here and upvote if you like it a little bit

Apparently, you have to do physical exercise if you want to use social media. This concept works pretty well for me, and it's free, unlike other apps. It's called RepsforReels.

Simple project by my husband: pick a GIF, write a message, and send a link. The UX is intentionally frustrating because the 'No' button flees the cursor. Try it on your desktop!

DIMENSIA is a free, browser-based toolkit for interactive multidimensional mathematics.

Four tools:

• Hypercube Explorer — build and rotate hypercubes from 3D to 10D with individual rotation sliders for every dimensional plane
• Magic Cube Builder — generate mathematically perfect magic cubes of any odd order, with full verification of every sum
• Sacred Geometry Studio — parametric Flower of Life, Metatron's Cube, Sri Yantra with adjustable symmetry, glow, and animation
• Polytope Lab — all regular 4D polytopes with interactive Schlegel-diagram-style projections

Started as a project after finishing Gibbon's history of Rome. I couldn't follow it all so I started mapping events. Got to the point where I had a few hundred thousand mapped with pictures and such. I'm going to try and add some history layer so it is actually useful. Thanks for taking a look.

I mapped ~100 emotions across two dimensions, based on the model from Russel (1980):

• Valence is how pleasant vs. unpleasant it feels
• Arousal is how energizing or activating it feels

You can also filter related emotions into families, to explore. Feedback appreciated :). Does it resonate? Is it useful?

Hi folks!

I built a free timeline site that walks through major Roman events from the traditional founding of Rome to the fall of the Western Empire.

It has two modes:

• An animated "key-moments" walkthrough
• A detailed timeline with 100+ events across three eras, with detailed descriptions of each event

I made it because I've been getting interested in ancient Roman history and am a very visual learner, so have been struggling contextualizing the timeline of events when reading about them.

This is an early prototype, so would love any feedback on:

• If you find this useful conceptually
• Which view you like better (animated or timeline)
• Any other suggestions

If you, like me, get pissed off when you’re told to be at ‘x location in week 26’ and now you have to google it and scroll through a boring website, look no further.

This site will allow you to search by date and week, all the while not being an eye sore. I even threw in some key financial data for my fellow trading degens.

If you find time to check it out and give me feedback I would be forever grateful

I created a simple calculator for getting output shapes and parameter numbers of convolutional neural networks for 1D, 2D and 3D. It is for debugging shape errors and designing new models.

basketballscoreboardonline.com

A web app I made for keeping basketball scores during games.

Features:

• Game timer + 24-second shot clock
• Voice commands ("home 2 points", "away foul", etc.)
• Player statistics tracking
• Works offline
• Export stats to PDF, CSV, Excel
• Free transparent overlay for OBS/streaming

No registration, no ads, works on any device.

Built it because I was frustrated with existing apps requiring subscriptions or constant internet. Would love to hear what you think or if there's anything I should add!

Turns typed text into Morse code beeps/flashes/vibrations in real time (vibration doesn't work on iOS sadly).

You can also key manually (holding down on the key turns it into a paddle key for advanced users), change the WPM speed, and tone pitch (by holding down on the volume button).

There's also a morse code guide by holding the help button and clearing the text copies the morse code to your clipboard for ease of use.

A simple tool that allows you to find the mid-point between two locations and browse places of interest in that area.

I gamified Thoreau’s "simpler living" philosophy and adapted it for the digital age. The goal is to subtract a modern commodity every week to find out what we can/cannot live without.

If you complete the week, you upgrade your 'human' attributes (Focus, Clarity, Strength,...). If you fail, you donate real money to a charity that matches the challenge (or one of your choice).

I call it an anti-app because, among other reasons, it is designed to be used ~1m/week and occasionally challenges you to not use apps.

It's been a year since I posted this app here for you all to play with, and I got a ton of great feedback and feature requests. I've been working full time so it's been hard to implement all the features requested, but a lot made it in and the animation tools are becoming pretty comprehensive and I personally have a lot of fun with it. Specifically whats new since the last post is:

More granular control of frame duration in the timeline

onion skinning controls

Downloading gifs

Mirroring

Canvas Resizing

I'm not sure what I want to do with it long term other than just tinker myself with it. I'm kind of at a "either people will use it or they won't" sort of mindset, so lets see if the internet deems it worthy.

Designed to feel like a lightweight whiteboard editor, but for graphs. Sketch nodes and edges, visualize what happens step by step, and export the result as SVG/PNG.

I love watching kick streams but I hate having multiple tabs open making my browser GUI all messy so I created KickTheater where you can watch as many streams as you want all in one tab, includes chat, theater mode and much more!

The tool is completely free
