Sheesh! Do these guys (PC gamers) have that much time/money
to spare that they are concerned with how *heavy* their
mouse feels? Prior to the development of this mouse,
were gamers busily *taping* COINS and other masses onto
their mice just to improve their score?? Is the mouse's
mass that critical to its use?
[Shouldn't there also be a huge selection of available

OTOH, it gives me something else to consider in developing a

why is it so hard to imagine that you want to do something with speed and accuracy, weight and feel can make a difference?

My PCs were purchased my our IT consultants. They have insane gaming
GPUs and weigh 42 pounds each, and are almost impossible to carry.
Nothing that I do (Spice, PCB layout, twirling SolidWorks models
around) needs that. I'm planning to dump them and get some nice little
Dells.
Gaming seems to be an addictive thing like TikTok or fentanyl. Natural selection should kick in on those.
I do buy expensive (over $20!) laser mice because they work on Ikea
varnish.
The Pi400 does come with a cute red and white mouse.
Unless you do a lot of video editing or 3D rendering
the GPU built into the
modern Intel chips is entirely adequate for 2D business graphics.

I still remember the good old days (early 80's) when the Swiss firm
Logitech started out by marketing the ETH Zurich Modula2 compiler and
bespoke word processing software. "Logiciel" being software in French. >(French language police would not allow the nasty English word)
Long before they started making any hardware. The mouse was an
unexpected consumer success when Windows took the world by storm!

I wish they would help with Spice. Yesterday we were running a pretty
simple power supply sim at around 100 us/s. It takes many minutes to
settle out, and it's hard to learn with such delayed feedback.

It will depend critically on how big the matrix problem gets but for

There are cosmetic differences, not structural/functional ones.
I've probably tested 200 different mice, over the years. (I can access probably 40 on any given day) None "fit" my hand; they're all just
rehashes of the same basic design/size. (gyromice being a notable difference yet still a poor fit)
why is it so hard to imagine that you want to do something with speed
and accuracy, weight and feel can make a difference?
Then a mouse would be the wrong sort of pointing device, wouldn't it?
E.g., signing your name requires speed and accuracy -- yet a mouse
is far from even being an *adequate* device to achieve those goals!
There's a reason motion controllers exist -- wouldn't it seem obvious
that a "pointing device" suitable for gaming should exist as a different beast, entirely?

Two instances would be confusing. One use of Spice is to train one's instincts and iterate a design.
At times yesterday, the power supply sim was running at picoseconds
per second. LT Spice allows one to set the max time step, but not the
minimum time step.
The Gear solver and some relaxed tolerances seem to be better for this
case.
In one recent case the sim kept stalling. I added a 1K resistor off to
the side, one end grounded and the other end connected to nothing.
That fixed things.
Inductors, especially coupled inductors, are quirky. A little ESR
often helps, but that may be random, like the 1K resistor.

That is odd. I can imagine adding a 1M resistor between some pair of
nodes might take the edge off it.

Resonant tank circuits with high Q can sometimes cause trouble.

no, it is games played with a mouse

playing a game is not signing you name

Trying to solve the matrix equations ( i.e. calculating the nodal
voltages from the G-Matrix and the current vector ) may result in
divide-by-0 errors when a node has absolutely no conductivity to
other nodes. Therefore, some artificial conductivity is introduced.
Otherwise you could not solve a circuit with 2 capacitors in series
and nothing else. The art is to choose the conductivity so that the
equation system can be solved without div by 0, without changing the
original circuit too much. Different spices may handle that
differently; usually there is an option to set the minimum conductivity
to GND if the automatic choice does not work.
There is no such thing in spice like a node that floats in nirvana.
AFAIR there is also a limit variable for g-matrix elements that are >considered for pivoting during solution of the equation system.
Last time I looked deeper into this was when I tried to compile
Spice 2G6 or so on my new 10 MHz 286 with 70 MB disk under
Interactive Unix. Oh, those 64k segments! Fortran memory management
was done by indexing out of the bounds of a small array. =:-()
That a student had a 70 MB disk all for himself was quite close
to hubris. The institute VAX had 2 * 300 MB Fujitsu Eagle with one
disk for us mortals.

Baseball *is* played with a bat -- because there are RULES
governing its play.
There are no "PC Game police" that verify you are
using a mouse instead of any other pointing device,
motion controller, etc.
The fact that folks think they need to adjust the *weight*
of their mouse in 1.7g increments is ludicrous (they
can't alter the center of *mass* so what about folks who
want the mouse "tail heavy").
[A modern penny is 2.5g... why not TAPE those to the mouse
wherever they want -- instead of being constrained to
load the weight in the special "weight tray" which resides
in a fixed location and orientation in the mouse]
The computer mouse is like a real mouse. It has been optimized by

Users don't select products based on the suppliers profits.
I buy a fabulously expensive ($19) Dell laser mouse.
Suppliers profits depend on users selecting their products.
Most people
select on what looks nice - by the time they discover it gives them repetitive strain injury it is too late to change it and the supplier
has pocket the profit.
...So they chuck it away and buy a different
model of the same make because it looks nice ...and so on.
