Group Build prototyping phase

[matt3o]

Will the case/plates have support for ISO?

yes

Why can't you just use Cherry-stabilisers.

7bits emoticons are so different on Tapatalk, his sad face is even sadder somehow.

[7bit]

I should have set up a simple language for those cut-outs, instead of hard-coding them (write-once) ...

[DanielT]

Ok, we have the PCB schema ready for printing. I'm willing to produce about 25 prototypes (that might be very likely all the PCBs we will ever produce). I'm not making a profit and I don't think I will be selling them outside our GBs so I can't afford to give prototypes away for free.

I would like to know if there's interest for such a thing and if 25 protos would be a realistic number (I could do less than that but price per PCB would increase).

Please bear in mind:
- These are prototypes! there's a chance that the PCB won't work! Unlikely, but possible!
- PCB quality will be very high (higher than hypermicro prototypes), and probably white
- the cost per PCB should be in the 20-35 euro range (+shipping). To that you have to add an USB port that I will provide (about 1 euro), the Teensy (15-18 euro) and diodes (1 euro). The USB port is not mandatory but a nice touch.
- the keyboard does NOT support PCB mounted stabilizers! You NEED a plate!

What about the case?
I will experiment 4 cases:
- layered sandwich like
- plate + 3d printed bottom
- top and bottom plate + 3d printed middle layer
- barebone: top and bottom plate with standoffs

You'll be able to buy any of them based on your budged. The cheapest (the barebone) should be around 30-35 euros. The most expensive around 60-70 euros.

I'm interested in a PCB and a layered sandwitch case. Have the switched, teensy and costar stabs ready.
I love the layered design more for the case, but I will take whatever will be available in the GB.

Done!

Now, I can generate the plates ...

Will the PCB/plate support also offcenter CapsLock ? I like that on my boards

YES!

[DanielT]

Cool because I love my Cherry ABS caps and stepped Caps Lock

[matt3o]

where's the central stem in that spacebar?

[M1K3L08]

May I suggest posting this on GH or Reddit to gather more interest?

[SL89]

I'd let matt3o take care of the publicity, who is to say he wants that much attention.

[DanielT]

The spacebar is standard 7u or 6.25u for Cherry profile, only the 6u is weird.
I can take some photos next to SP spacebars.

[scottc]

Oh yeah, the Cherry 6U is a real pain. None of the three mounts are the same as SP. To put the 6U ABS spacebar from DSA Granite on my Cherry, I had to add three new mounts to it from other keycaps.

[gianni]

I could be interested, how long until a kit is shipped?

Btw, I hope that you will sell very soon also a 60% version

I guess if we start right away, approx 1 month from today to have it in your hand.

[pyrelink]

I am also interested in the layered sandwich case and a PCB.

[pexon]

Can I register interested in a proto board?

[Memoren]

I am also interested in buying one of the prototypes.

[JohnVenture]

Would the prototypes only be 60%? Matte3o I believe you mentioned working on the 75% pcb a while ago?

[matt3o]

60%?! there's no 60% here

[JohnVenture]

Fine fine, I see you are very touchy when it comes to every bit of extra %

Then would there be a prototype version that includes the F row?

[SL89]

60%‽‽ there's no 60% here

ftfy

[idollar]

I am interested in the layered sandwich case and a PCB.

[rsadek]

This is a great project! Count me in for a PCB / sandwich case .

[matt3o]

Fine fine, I see you are very touchy when it comes to every bit of extra %

Then would there be a prototype version that includes the F row?

that would be the next step.

[copter]

You can count me in for PCB and layered case. I have been looking into this project for a while and this exactly what I have been looking for.

[sphinx]

I'm sorry for parachuting onto this thread like this, but i only went through the last 5 or 6 pages..

I'm interested in getting a PCB + Case, what do i need to do?

[matt3o]

a quick update.

I don't want to run a prototype on teensy now and a more refined version less than a month later. So, if I can have the PCB made with the integrated controller since the beginning I believe it is better. I'm exploring this possibility and get back to you ASAP!
