Focusing on a dot can seem non-simple when you are computer code.
I made this static `term` class, with methods `clear`, `write_at`,
`where`, and `size`:
class term:
import curses
import sys, tty, termios
curses.setupterm()
_cup = curses.tigetstr('cup')
_clear = curses.tigetst
>>> import curses
>>> curses.setupterm()
>>> curses.tigetstr('cup')
b'\x1b[%i%p1%d;%p2%dH'
man terminfo:
cursor_address cup
cmmove to row #1 col‐
umns #2
the command to position the cursor is "cup"
i dunno! looking up tput commands doesn't sound very stabilising when
you're focusing on a dot!
i am thinking of three options for that:
- home the cursor and move by rows and columns using individual characters
- find the cursor-pointing control characters
- use the curses library
i'm thinking i might consider using curses's tput functionality, kind
of a middle ground between the last two o
now, that pointing code is pretty dumb right now. it just says that
whatever to the left of it is a period, no matter where it is!
it could be nice if it checked whether it was or not
but i was thinking i might want to place where it is on the screen
a first step to adding a little bit of code to that interface could be
breaking the period away from its pointer.
this file outputs the same text, but the two parts are slightly separated:
print(".", end='')
print(" <- this is a period")
here's a first sketch, kind of like an interface design. we actually
want it smarter than this:
print(". <- this is a period")
[note: farther down the file there were a couple things about force!
it looks like learning about the force exerted by and on a magnet
would make sense.]
i'm thinking of building a python script that kind of "focuses on a dot"
like, makes a dot and points to it.
maybe i can build more focusing-beh
. <- this is a period
bagaba!
One of them is B = Magnetic Field.
Units are Tesla (the engineer-researcher, not the car, obviously), of
flux density.
It says B = mu H, and that mu is the absolute permeability, and H is
the "magnetising force" in ampere-turns/meter.
I'm not sure how this relates to force.
Also, it says there a
There are a few terms defined in this file. I imagine I didn't write
them all in. I was still learning.
So, what are magnets made of, equation-wise? What important properties
do they have?
In fact, if I had a chart of a magnets field, I bet I could learn to
look at that chart, and figure out what it implied about the
properties of an equivalent dipole, by considering behavior at a
distance.
But I'd need to learn how to do that! Learning is super fun! With this
stuff, I often do it b
Heck, I could just simulate the magnet, if needed, to solve for this!
I bet, if I have a way to integrate something over a magnet, then I
can solve for its approximate equivalent dipole.
Skipping through snippets of this file, I get the impression there are
different ways of engaging things like this:
- One can integrate over space in detail
or
- One can simplify things to well-known fundamentals (like a dipole or
a monopole)
I get the impression there are different models of magn
magnets are interesting!
i've got a file open called 99-Magnetics.txt . I think this file could
help me with this tiny puzzle. I bet there are other resources
elsewhere, too!
golem projects are stupid! yes indeed!
what's interesting is magnets. i'm interested in having an idea of
what formulas there are for describing the force and torque a magnet
exerts on another magnet!

recently i looked at an old project. it was nice to hold an idea of a
project!! but it got harder.
maybe it would be more fun to look at just a part of a project.
no? no evil golems?
the bits on analysis left off this way, it looks like i was struggling
with inhibition:
I think it owuld help to consider magnetic monopoles.
I settle don looking to solve it algebraically
based on the formula for force and torque.

ooh i mentioned cold
you could make an ice golem!
this next section has numbers in it:
I'd like to be able to levitate the magnets an inch to the side of the base.
- [X] find the kind of magnet with highest power / mass (likely neodymium)
-> note: dimensions of magnet affect behavior?
These magnets have maximum temperatures depen

on to evil golems!
it would be nice to create an avatar of peace! that would be
wonderful! i dunno if robotics would be the priority in that project
though. more important to do peace stuff.
also my psychological programming could dislike the project more if
it's for peace
i'm worried the fire golem could be scary
how about a water golem? or an air golem? instead?
I found three files in a folder path containing 99-AssortedFun/99-Golems
the files are:
00-Talk.txt
01-Design-1.txt
99-Magnetics.txt
I wonder why magnetics is last?
i actually found an instance of this in my todo repository, which was
after the annex
i'm thinking the project was in my "annex" folder which is hard for me
to find nowadays
maybe i'll look for it briefly, then check my githubs a little for
evidence of this project, and then start anew
i'm not familiar with the equations!
i wonder if i can find my notes from a few years ago when i last poked at this
so basically the first microprototype for me is an array of tiny
electromagnets that can arbitrarily move a tiny neodymium magnet
around.
i basically figured out this is not that hard to do, but if you're not
familiar with the equations there can be a big stumbling block.
but remember: you have to use magnets or something to prevent all the
joints from touching each other, floating in the air. that's what
makes it a fun puzzle.
imagine a tiny fire golem, flaming lamp oil pumping over all its
parts, streaming from one part to the next, stomping around on your
desk, burning in fury!
i haven't gotten to the point where the challenge of not burning the
desk is relevant yet
basically a golem is a robot that uses magnets to hold where its body
parts are, so it looks like they are magically levitating, and it uses
whatever element it's made of to camouflage its robotic workings.
obviously the primary golem is the _fire golem_, because it seems the
most evil. but i also designed a water golem, an air golem, a rock
golem, and came up with some small ideas to make other golems (like a
book golem!)
there's a good chance i've mentioned this project on this list before
anyway, you'd need to make a tiny golem prototype first, right? before
making a big one?
one of the projects i began when i was confused was a levitating
golem. i think it stemmed from a daydream around making me really
evil, maybe i could summon evil golems that terrorised something. i
dunno. not big on evil. but i like puzzles.
i thought i'd make very _small_ elemental golems. it se
