Keyboard Keycaps / Re: Adapting Space Cadet-like Alphas to a New Keyset

with an emphasis on commomly used engineering and math symbols.

I saw you've since moved on from this project, but I like that practical focus. I took a similar direction and ended up creating a keyboard with math symbols and Greek letters printed on the keys, with matching key combinations to type them. The idea was to make those symbols easier to find when writing technical notes.

Hey GH! I'm a new member here, I'm a big nerd and i love math. I've been seeing the pi keycaps a lot lately, but i've never seen one with i, the imaginary number, and e, euler's number. a keycap would an integral sign or a contradiction sign would be awesome as well!

have such keycaps ever been made? if so, can anyone point me to such a thread? i'd be so down to get some keycaps similar to this.

I went through the same search myself! I eventually ended up creating a keyboard specifically designed for mathematical writing, with math symbols and Greek letters printed directly on the keys, and key combinations to actually type them.

Symbols: Sigma summations, Capital PI, surface integrals, gradient and "curl" symbols

I'd pair those caps with a matching symbol layer, so the symbol printed on each key can actually be entered from it. Having ∫, ∑ and Greek letters visible would be especially useful for symbols you use occasionally and haven't memorized yet.

I plan to use QMK since it supports Unicode

Old thread, but I ended up building something very close to this: Nitrax, a keyboard with printed math and Greek symbols.

My approach was to have the keyboard send key combinations and let companion software handle the character insertion. I've documented the layout and software approach in this technical description of my implementation, if it's useful to anyone working on a similar project.

it relies on custom keycaps for legend identification or pure muscle memory.

That's something I focused on with Nitrax, the math keyboard I designed. It uses modifier combinations too, but the math and Greek symbols are printed on the keys in two colors, so you have a reference when you forget a mapping.

I've explained how the symbol layers work here. The idea is to make the additional layers visible.

Have a layer with lowercase greek letters and math symbols

I know this is an old build log, but I'm curious how that layer worked out for your technical documentation. Did you use it to insert Unicode characters directly, or to enter commands for an equation editor?

I'm working on math input tools myself, so I'd be interested to hear which symbols ended up being the most useful.

Then we're back to this,  Mordor model.

Mordor model worked, because the elves and humans were as dumb as ****, they had neither satellite surveillance nor ballistic Stand-Off Munitions.

If ur000p  actually went full fascist,  and got MORDOR started,  welp,  they'd let you put in the 10 trillion dollars war factory  annnnd Oreshnik your investment,  pooof,  gone in less than 30 minutes (yes these munitions are that fast).


It can't be done.  not IN ur000p..  the fighting STYLE, and fighting CONCEPT of ww2 is Permanently OBSOLETE.


So, what would ur000p really provide if it came to that,  THE ORCS right?. Someone much smarter than Tp4 puts it best, ur00p is not Churchill this time around, they're private Ryan.

And, one must wonder if the average ur00pn guy will actually come running, on call-to-arms.


Looking @ u franz.  it seems like your peasant class is burning down patris and looting the worthless luxury brand clothing.
-- The minor upside is, well it looks like the peasant class is still very stupid, as they steal cloth when they should be stealing potatoes.  Cities have 2 weeks worth of food in them, something goes wrong,  Hermes bag won't save you,  the Potatoes would.
-- Tp4 recommended loot, RICE + PASTA + Oatmeal, Potato, Tomato + Tomato Paste, Apple, waxy MELONS, Cabbage, STICKS OF BUTTER, Canola OIL

Sooooo..

Frnz bond collapse,  now,  the contagion MAY also implod dat Uroh.  Depending on how the ECB handles it, do they let franz collapse and close it off, or do they print print print, and depreciate the whole to dilute the pain.

So,,, watch this carefully.

See,, US, can screwup really really bad, but u know what, it has something it can sell, OIL, albeit the crappy kind that can only be used for gasoline and plastics (not profitable), but not great for diesel/jet (the profit)

ur00p does not have any such things. Belgian only became rich after they raped/enslaved/genocided  Afrika.   This is the root of all the "old wealth" colonial systems of ur00p.


Push comes to shove, TODAY,  ur00p has nothing to sell, that is to say their currency has no real peg.   The PEG WAS the US DOLLAR.

But now that the US hits a major inflationary crisis, well, if we inflate 1%,  Ur000p holdings depreciate 9% on 10 year, 30-50% on 30 year.

Every dime the US has spent in its 4ever wars actually CAME from ur00p /Jpn/ vassals.  the vassal gobaments bought every last piece of tha debt.


ur00p is NOT like the US,  the US has a moat, admittedly (shrinking),  ur00p does not even have roads, and their castle is a made of straw..


The "leadership" of ur00p is betting on a WAR FACTORY revival.  This is incredibly unrealistic,  if you have massive inflation, AND NO ENERGY COMING IN, a situation where ur000p can't buy energy AT any price.  What can they realistically produce?

They would have to entirely rearrange, and go full fascist, where PROFITs are mere ink stains, and you're simply running the Mordor model.


This type of arrangement, worked 100 years ago, BECAUSE, we didn't have communications, and we had a mostly peasant population. Importantly, very cheap energy, because back then it "Seemed" limitless,  just dig it up and burn.


You think the average ur00pn guy will sign up for Mordor? ur00pn childrn in their heart yearns for the mines, to be lowered into black chimneys to clear the War Soot. No, one would think They'd rather burn the factory down.  You can't make 'um and the average uroopn person KNOWS THAT.

A peasant you can coerce / Trick / Manipulate,    the Average Chav ?  Nah,  they'll molotov you.  Peak evidence, FRANCE. WITNESSSSSSSS !!!!!!!!!
