eavesdraw is one shared page anyone can draw and write on, with no accounts. But once you draw or type (it asks first), you’re public. Your work is labeled with a made-up name plus your network and city (“a nervous cuttlefish · verizon, queens”), and hovering it shows part of your IP and your browser. Anyone else who has drawn can open your full record: headers, TLS details, the site that linked you here, etc. What any site can already see. To look someone up, you have to be public too, and they’ll see that you looked. Records are trimmed after 30 days, and my moderator actions go in a public log.

It runs on one Cloudflare Worker and one Durable Object (SQLite plus the WebSocket Hibernation API) on the free plan, with perfect-freehand for the ink and no other dependencies.

Would appreciate any feedback!

I was interested in the music artists I liked, and wanted to create a much more comprehensive way to view the connections artists may have with each other. It's just a fun project, let me know what you think!

Data comes from Youtube Music public playlists for connections and Deezer for artist info (since spotify/apple doesnt share anything)

I’ve built an site where you can add your referral code or spin the wheel to unlock an referral code, it’s all random and one app, one spin, one time.

built it so I don’t need to beg my friends to use my mine, so don’t you now!

Hey, after rewatching all 25 Bond films I wanted to see every filming location in one place, so I built this. It's a free fan project. I'd love corrections and missing locations, there's a "field report" form for that.

I’ve been building this antenna/EM simulator as a side project:

https://rotemtsafrir.github.io/dipole_sim/

The idea is to make it easy to place antennas, change their parameters, and immediately see how the fields and interference patterns change.

Right now you can use:

• center-fed dipoles
• Hertzian dipoles
• small loop antennas
• linear antenna arrays

The arrays are probably my favorite part so far. You can adjust spacing, phase difference, element count, orientation, etc., and see beam steering / broadside / end-fire behavior directly.

You can switch between electric field, magnetic field, and energy-flow visualizations, and pan/zoom around the simulation.

The antenna currents are prescribed, so things like mutual coupling, impedance, and passive conductors are not solved yet. I’m trying to keep it fast enough to be genuinely interactive.

I’d love to hear what people think—especially if you notice anything physically questionable or have ideas for features that would make it more useful.

Happy to answer questions about the sync and the looper.

I made a 3D interactive solar system you can navigate and set to any date between 1000 and 3000. The positions of the planets and moons are computed from VSOP87-type models and checked against JPL Horizons data, accurate to within 30 arcseconds for planets and 30 km for the Moon over 1800-2050, so eclipses, alignments, and moon phases are physically real. It's still a work in progress, so feedback is wanted. If you try it and something feels off, confusing, or worth adding, I'd be glad to hear it.
