It also means there may be some room to order prototype PCB's easily as part of a board with some of their PCB's.

If you want, I will ask around and get some options.

(also the option to ask people about plates too, I know a few guys with CNC mills that might prototype for us too)

that's great, please ask your contacts and keep me posted.

What physical size do you expect the final PCB to be?

I reckon 15.5 units wide to be about 295mm wide, by 5 units at about 95mm.
We looking at single sided or double sided?

yes, that is roughly my estimate 300x100mm, I haven't got the schematics yet. I think single sided should be enough. I did some quick online quotes and we are in the €12-18 range

would you like a chassis like this?

all at the same width (so only 1 case design needed)

I'm probably the biggest fan of this one with the odd-shaped enter key. What is the size on those shift keys?

left 2u
right 1.5u

And the bottom row is 1.25?

right

I've got some very interesting info regarding the case. There's a process to make low quantity of plastic cases without the need of a mold. With this technique one case would cost approx 15/20 euros. That would be pretty awesome and would make a custom keyboard pretty inexpensive. I need a 3d model to get a final quote.

I assume that means it is 3D printer? If so, what type is it using?

they are thermo-sculpted, I believe the technique is called "thermoforming"

Aha, I have used those before, we call them vacuum formers. I am not sure about the final quality we would get from it.

I would much rather have the CNC milled case/plate hybrid like you linked earlier up.

from the samples, quality seems pretty good if you keep the model simple. I would prefer CNC as well but it's expensive. An alternative would be to laser cut a series of aluminum sheets until you reach the right height (the sandwich effect).

Yeah, thats the same effect I used for my iMate case, but using acrylic. I will give it some thought. If we used my 'end piece' design then we could get those end bits CNC'ed from Aluminium, with then being a much smaller size, they would likely work out a lot cheaper.

I will give it some thought, see if I can think up some other solutions.

I've found a service that can laser cut sheets of aluminum up to 5mm and up to 10mm for S235JR steel... which means that with a couple of layers you can cover the whole keyboard height

Very Interesting. How much would that work out at for a case?

I need to design all the DWGs first. I'll try do that in the weekend

Any thoughts of combining this with the Deskthority ALPS Project? Because that would be awesome.

FInally! whenever it comes to compact layouts people either: do it like the noppoo choc mini, or like the poker.
It's nice to see something done in this way, like the choch but without the goddamn f-keys.

/Off topic.

yes, I plan to make the plate for ALPS too

I have also been thinking of vacuum forming keyboard cases because it can be so inexpensive. I was thinking of a poker style case where you don't see the case that much. I have also seen people doing vacuum forming at home which looks very cool.

That case looks awesome!

Well, that's the best news I've heard in the keyboard since I stumbled upon the Ergodox.

Great layout!

With the ANSI layout + ALPS, I'd definitely be very interested in testing or group buy.

the problem with that ANSI version is that we would need a GB for the keycaps too (weird return and 5u spacebar). And as far as I can tell the 5u spacebar is only in DCS family. Don't know if Round4 SA has 5units spacebars... lemme check

For me personally, I'd be using the alt keys as cmd keys. I definitely don't need a right-cmd (could be filled with spacebar to make it more standard). Not sure how many people would feel similar.

nope there's no 5units in SA family, just checked.

the test boards will be with a 6unit probably so I can use the DSA retro. If there's enough interest (say 100 units) we could run a group buy for the keycaps as well. I'll try to include the small J shaped key in the second round of the retro set.

For the weird return key, you could just settle on a 2x key. I know that would leave a small gap. But it would work.

For a keycap group buy, there could an option that just includes the irregular length keys, like the shift keys, return, space bar, etc. rather than the whole set. I am sure you have considered this already.

This might sound like an ignorant question, but the intention of this project is to squeeze a more useful compact layout into a 60% case, correct?

the purpose is to create a compact layout with default staggering and the arrow keys. Usually compact layouts with arrows turn down on default staggering.

For this purpose we will probably need a custom case (that I'm designing right now). The ANSI would be feasible actually (so you could fit it into a poker case), but ISO would be more complex.

On a side note... we have to find a name for this project
