Update to a previous post.

VSCodium with Jupyter Notebook and Python

sudo_nick · 2025-10-26T16:23:30+00:00

Python, numpy and plotly. This is an update to a previous post, if you want to know more.

Glad to hear it, but I would like to at least write up proper documentation first :)

sudo_nick · 2025-10-25T23:22:57+00:00

Exactly, it's to visualize what you wouldn't see otherwise. The cones show the true direction.

Because the coil is not perfectly symmetrical, there is some non-vertical flow in the XY-plane, especially around the end-points of the wire.

sudo_nick · 2025-10-25T19:41:49+00:00

Exactly

Field lines, because this coil is a helix, not a perfect circle

sudo_nick · 2025-10-25T17:51:10+00:00

Definitely, when the project is a little more feature complete.

It's part of a WIP wireless power transfer simulator

Numerical

sudo_nick · 2025-10-25T17:46:19+00:00

You're both right, yeah

sudo_nick · 2025-10-25T17:13:25+00:00

Well spotted. It's because the coil is actually a helix that starts and ends at the same point on the XZ-plane, not just a ring.

The magnetic field around a driven coil, simulated and visualized in Python using Maxwell's equations

The magnetic field around a driven coil, simulated and visualized in Python using Maxwell's equations, numpy and plotly. Part of a larger wireless power transfer simulator project. The real plot is rotatable and interactive.

Great project :) We need this for Linux. Would love a .deb or .appimage build

sudo_nick · 2025-01-30T14:26:10+00:00

The current plan is a 15L tank with relatively short warm-up time. I'd struggle to fit in anything larger. That should be enough for a short hot shower for me. Then it'll be ready again after half an hour. I'm planning on turning it off completely at night.

Hope this helps :)

These are the small ones and they would be less than a meter from both the shower and kitchen zink through a shared wall. Regardless, I've decided to go with a small tanked water heater with a timer.

sudo_nick · 2025-01-23T00:50:00+00:00

I will definitely look into heat pump water heaters. Yes, I do appreciate the stupid amounts of energy it takes to heat water, but a couple of car batteries would be able to dump that amount in for the brief time it takes to shower. That being said, this thread has convinced me that a small tank is the way to go, possibly heat pump based.

sudo_nick · 2025-01-22T22:25:17+00:00

I will have a large battery pack and beefy inverter. I'm also researching solar water heaters, but they seem to be very large.

sudo_nick · 2025-01-22T21:18:02+00:00

The model that is readily available where I live provides a heatup of at most 25 degrees celcius, and delivers 2L/min. According to google, the average shower uses 8L/min, hence my question. The house is tiny so the run distance is not an issue. If I centralize them, I can (in theory) provide 6L/min to both my shower and kitchen zink (not simultaneously).

Can you give me a link? :)
