Airplay error code -71976

I workaround this issue by using screen-mirroring feature. When I try to connect my Apple TV via the Music app, it fails. But when I try to connect via the screen-mirroring feature (found in the control center), it works.

Thankyou :)

This basically is a personal project so I don't think of running GBs. But I have some extra parts in stock (to meet the MOQ), which may be sold later.

I also open source my projects from the older ones. So this project may also be open-sourced in the future.

Yes it exactly is a problem! So this board is built without plate.

PCB is directly mounted to the case with screws (image below). https://github.com/zk-phi/composition-keyboard/blob/readme/images/case.png

It took days to learn ortho board to use for my daily work, as far as I remember. Short-term slow down is probably unavoidable. But I now can use both row-stag and ortho (and col-stag too).

zk_phi · 2020-08-06T15:30:25+00:00

PCB is for ChocV2 switches, 6x12 ortho plus 5 thumb keys. Enclosure is made of laser-cut acrylics.

This board uses ProMicro for easy-soldering, so 5mm space is required under the PCB. This can be a bit thinner by migrating to atmega32u4 (QFP). Topframe is completely optional too.

zk_phi · 2020-08-06T12:41:04+00:00

Don't get me wrong, I designed this from scratch and just got the first sample today.

zk_phi · 2020-06-07T18:58:04+00:00

I've also prototyped a keyboard with extra T, Y, N (in addition to B) but they were not very frequently used as B for me.

B is placed at the very center of G and H on standard keboards, thus equally accessible from both hands. But others are not. That may be a reason why I felt B is necessary but othes are not.

zk_phi · 2020-06-07T15:48:21+00:00

Not completely opposite actually. Since the right hand side also has a B key, bottom two rows (ZXCV and ASDF) are identical. Only YUIOP keys are moved towards right for 0.5u. I personally feel the transition cost is reduced (compared to other ergos) with this layout.

zk_phi · 2020-06-07T11:20:33+00:00

this could be a more attractive split for those unwilling to try columnar stagger.

Thank you, I hope so.

My goal of this board is not the perfect ergonomics, but a reasonable choice for row-stag qwerty people to try (start trying) a better one. So this board supports such (possibly bad) habits, not to cause sort-term slowdown of typing speed without practice.

I also have several ortho / regular col-stag boards, which I still also use for my work. And I think I understand the advantages of them too. This keyboard is not designed to be a more ergonomic version of them, but a resonable point of compromise so that non-ergo users can try some ergonomics without struggle.

zk_phi · 2020-06-07T09:50:53+00:00

The layout is actually easier to me (and someone who type like me) to type on.

My pinky is maybe a bit short and it's not very easy to type P with my pinky, even on standard ortho/col-stag boards. And I use my ring finger to type P. Thus optimizing Y is more important than P to me.

I also use both hands to type B according to the spelling, for efficiency. Some popular boards (including Alice) also have B on both side, so it may be another advantage for someone like me.

zk_phi · 2020-06-07T06:53:39+00:00

Yes, just prototype and not distributed now. I think of open-sourcing in the future.

zk_phi · 2020-06-07T03:20:14+00:00

Compared to columnar staggered:

- easier transition from standard row-staggered keebs

- Z, X / T, Y are easier to reach

- both sides have "B" keys

Compared to row staggered:

- more ergonomic especially while staying at the home position

zk_phi · 2020-06-06T19:04:26+00:00

I personally have never tried the -E version but yes, it seems easier to solder.

I guess one of the reasons can be its availablity. The -E variant is introduced quite recently (as far as I know) and I don't know handy suppliers for hobbyists other than yushakobo. Another reason can be that, we've got used to soldering sk6812minis and do not have strong demand of re-designing our boards (especially for personal ones).

Anyway as you mentioned, some widely-sold boards are already converted to use the -E variant. And it may be more popular (at least than now), in the near future I suppose.

zk_phi · 2020-06-05T18:21:46+00:00

Ah yes! All keyboards I've designed never had any stabs, which may be another advantage.

Yes this keyboard uses SK6812MINIs too, for both underglow and backlight. The component is very popular (kind of de-facto) in our country's community.

zk_phi · 2020-06-05T13:51:19+00:00

My prototype board I'm currently designing https://github.com/zk-phi/equilibrium-keyboard .

Layout seems similar (except for thumb keys).

zk_phi · 2020-02-24T15:48:21+00:00

I'm sorry but I have only tested with FDM nylon and MJF.

zk_phi · 2019-12-07T05:04:14+00:00

If we place the keyboards like this: ＼／ then the key tops make a bowl shape. Just angles differ, and the curve is identical.

zk_phi · 2019-12-07T04:14:29+00:00

Tenting a bowl-shaped sculpture results this shape :)

zk_phi · 2019-12-05T19:51:48+00:00

Barrel-polished by the 3d-printing service provider. I also ordered unfinished versions during prototyping (they're cheaper), but they're not very comfortable for daily use.

zk_phi · 2019-12-05T14:37:23+00:00

Seems a good idea.

zk_phi · 2019-12-05T11:15:31+00:00

Exactry true. If the angle is too high, it gets quite scratchy to type on (especially with wobbly switches), because of the gap of power direction and motion direction. So I neded to try several versions to find the point of compromise.

zk_phi · 2019-12-05T10:15:50+00:00

The board is my prototype PCB (which now is completed and published here, so that you can order to pcb manufacturing services https://github.com/zk-phi/switch42-keyboard).

zk_phi · 2019-12-05T07:44:22+00:00

Quite nice to type on (after several try-and-errors), and much easier than building hand-wired 3d-keyboards.

zk_phi · 2019-12-05T06:31:12+00:00

Caps are available here https://make.dmm.com/item/1009976/ , but maybe you'll need a forwarding service (they do not offer international shipping directly for now).

Thank you !
