However, does it have capactitive properties? The model F flippers have either carbon black or short carbon fibers added to the plastic to impart electrical capacitance. Have you added either of these ingredients to your resin?
What a way to discourage people from doing things. Erisie, demonstrate the guy yer middle finger and proceed. Just plan for several iterations of PCB layout. CommonSense is much more forgiving - but no QMK, ever.

The best that you can do is join this project, and when it will be successful, making all the possible layout variations will be the obvious next step.

You're just unpolite and detached from reality. I'm trying to be realistic and to save a guy with good intentions some delusions. He doesn't even know how to make a pcb, which is the simplest task. He pretends to do alone what the most experienced guys here have failed to do collectively. Surely if he spends a lot of time trying he'll succeed, but I wonder why he shouldn't just contribute to this project and then adapt the outcome to his layout. He's just trying to fork this project into a new one without knowing anything. Since I respect this guy and I don't like to make people waste their time, I've politely pointed out that his task is very difficult. On the other hand you're having fun looking at a guy that tries to do completely alone a very complicated project, forcing people that are working toward another objective to help him, hijacking a thread that his devoted to make a model m with a standard layout.DMA wrote: ↑03 Aug 2020, 03:56What a way to discourage people from doing things.

* plates don't need to be curved (see wcass' gorgeous CNCed beast of a keyboard)
* plates don't need to be metal - just strong enough to withstand the force of the springs. Acrylic is A-OK.
* foam is not indispensable - it only affects the sound. Note the word. Not "enhances". Not "improves". Just "affects". Nothing more, nothing less.
* Ground plane is still required under the pads. Tin foil is perfectly adequate for the task, just put a mylar sheet on top of it. Should you want sometihng more substantial - again, wcass has shown us the way of 4-layer PCB (borderless, too).
Guilty as charged.
Do you have a psychiatrist license to diagnose psychosis? If not - care to apologize?
Suuuure.
Neither did I, four years ago.
And what is wrong with that, exactly?
Yeah. I ended up spending $3k on a single keyboard. But it's on my desk and it gives me joy every day.
Becase his is a _completely_ different project, he won't be able to reuse ANY parts. The only common parts are barrels, flippers, and keycaps. All of which are available commercially as of today, in virtually unlimited quantity.
Fork? Read the message, he's sanity-checking his plans.
What exactly is wrong with that, again? Everybody needs to start somewhere.
No, you were just being a jerk. "I don't know how and why you think that you'll be able to succeed" is far from polite and a light years away from respectful.
It's not "very complicated".
Waitwhat? forcing? I don't see any guns pointed to anybody's head.
It was, indeed. Four years ago. Even two.
See? I wasn't even aware of the existence of the CommonSense controller until I read it here. I thought my options were limited to QMK and xwhatsit.
Gianni, question: if I wanted to "do [it] alone", would I use an existing design as a template? Would I come to a forum to ask for help on the project?
I have never done any such thing. All I did was asking whether my modified PCB layout design could work, and, if not, what changes were needed. At any point I have "forced" or "hijacked" anything at all. So stop saying that.

That is a good starting place.
Just two guys trying to divert the thread from remodeling the model f to making from zero a model f with an ortholinear layout and asking for help here, publishing pcbs made with photoshop, with so many errors that nobody wanted to look at those drawings.
It's actually interesting, because they are insanely smooth. I need model f to compare but it's definitely better than model m.
I am not forcing anyone to do anything. Do you even understand what "forcing" means?
Unless they are "nobody" to you, I already got feedback from wcass and DMA on my idea.
stop with this spam show, nobody cares, write to me with a pm if you have something else to say
I followed your advice, wcass. I redesigned i$'s layout to make it work according to the specifications (six rows, 22 columns, for a total of 113 potential keys) and this is the PCB result:wcass wrote: ↑05 Aug 2020, 03:47A basic principal of capacitive and contact keyboard matrix design; rows and columns should intersect exactly once.

I've had the FSSK, loved it. But I actually need the windows key as a lowly windows programmer. I know you can split the shift on the FSSK but eh. The new Mini M looks sexy too, and for a good price, yea that's my capacitive buckling springs endgame there
Well it's moreso because the SSK assemblies in mine brokeMuirium wrote: ↑20 May 2023, 11:35Ask Ellipse, the man behind them. He’s active here on DT, too.
I know where you’re coming from re: shell compatibility. His aesthetic is… clunky to the point of brutal. Don’t know if he’s done us a favour and kept his design within IBM’s shell tolerances. Certainly wouldn’t count on it until proved.
Well, the first one started to crack because SSK plastic assemblies are VIRTUALLY CRACKING out of box from the stress they're in. And then the other one fell off from a high shelf where I was storing it and it split in half completely.
