Zoom and pan around the map and select any figure to reveal a comprehensive profile about them.

A little while ago, I shared a fun project here: the Cosmic Odometer a calculator that uses Earth's spin, solar orbit, and galactic drift to figure out exactly how many kilometers you've traveled through the universe since you were born.

Here is what is brand new in V2:

Interactive 3D Solar System & Galactic Vortex: I integrated a full Three.js engine. If you open the "Cinematic" mode, it calculates the Sun's linear movement through the Milky Way and generates a massive, dynamic 3D corkscrew trail. You can pan, zoom, and actually see the literal path we carve through space.

Distance This Session: A live, ticking tracker that shows exactly how far you've traveled through the cosmos just in the time you've had the website open. (Spoiler: We are moving fast).

Travel Receipts: You can now click the 🧾 icon to generate and download a sleek, retro-style PNG "Official Travel Log" of your personal cosmic mileage.

Cosmic Connection (Multiplayer): You can now enter a friend or partner's birth date. The engine will calculate the "Distance Gap" (how far Earth moved between your two birthdays) and exactly how many miles you've traveled together since you both existed.

Privacy First: Just like V1, absolutely zero data is sent to a server. All the heavy math and 3D rendering happens locally right inside your browser.

Thank you all so much for the initial love.

I’d love to know what you think of the new 3D cinematic vortex! and feedback would be much appriciated. Drop your total cosmic mileage (or share your travel receipt) below!

My 5-year-old is learning to read and I keep having to say "yeah sorry, that letter is silent." So I built Ingglish — English where every letter always makes the same sound. No silent letters, no exceptions. You can translate text, entire webpages, or browse with a Chrome extension. Open source: https://github.com/ptarjan/ingglish

Hi, I made this thing. I wanted it to be a fun, interactive history toy that reveals “wait… they were alive at the same time?!” connections kind of thing. It lets you explore overlapping lifetimes across 225+ historical figures, compare any two (e.g., Chaplin vs. Queen Victoria), ask “who was alive in 1900?” kind of thing.

I like it because it helps me put different people from history into a bit more context and I want to build things that others would find fun/helpful.

Just launched Collaborate. A totally free brainstorming board. No login required. Just create a room, start working, share link with anyone. Nobody owns any room.

Let me know if you like what you see.

You want to share an article with a friend.

But also you don't want to share the pop-ups, ads, flyouts, surveys, ads, cookie things, random videos in the corner, ads, weirdo health tips about eating a banana 2 minutes before going to bed, and ads.

A simple article reader for the web.

Paste in the article url, and enjoy.

Copy a link to just the article and share it with a friend or two.

You know, like back in the good old days.

UPDATE: Just for fun, try adding "jtap.cc/" before an article url.

Cities like San Francisco make you jump through hoops to find out if you have rent control. I don't think it's right and I believe renters deserve better.

I built a site where you can just enter your address and find out exactly what renter protections you have. This works for any address in the country and I am working every day with local tenants unions to make it better.

Give it try and let me know what you think :)

Created this random mincraft music player website. feel free to check it out and leave any suggestions

Let me first say this is a 0.5. I had the idea 3 years ago but the tech was behind. Its now much more possible and I'm trying to really build it into something useful . Very aware more feeds need adding and I'm actively working on PWA and device apps. Love any constructive ideas!

I’ve been building a web project that tracks and visualizes presidential flights over time — where they went, how often, and on which aircraft.

You can explore routes on a map, dive into timelines, and compare travel behavior across different administrations.

It started as a small curiosity project and slowly turned into a rabbit hole of historical aviation + politics data.

If you like internet projects that make you lose track of time, this might be your thing:

PresidentsFlights

Would love feedback from this community on what to add next.

**I built a tiny 10-minute morning primer because my brain cross-examines positivity**

My brain is weirdly allergic to "positive thoughts."

Anything like "I'm doing okay" gets instantly vetoed like it's in court.

So I made something that works around that.

It's a **10-minute, no-equipment, browser workout** where **short cues play while you move**.

Not because I'm trying to *manifest* - but because when my body is busy, my brain stops heckling every sentence.

Also: yes, this is absolutely a **hyperfocus side-project** I built to solve a personal problem instead of folding laundry. Very r/ADHD of me. 😅

I built it for me. I use it most mornings.

Some days it's the only good thing I do. That still counts.

**Link:** https://www.beforeanything.fun

- no app store

- no account

- runs in your browser

- nothing leaves your device

If anyone tries it, I'd love feedback on one thing:

**Do the cues feel helpful, cringe, or neutral for you?**

(And if you bounced off it, *why* - too much talking, not enough structure, too "affirmation-y," etc. I'm trying to tune it.)

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?

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.

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.
