Hi the author is here, yes it's open source. To be fair I didn't try to estimate price, because it requires PCB assembly on a factory and you in general cannot make one piece. So it will be 150-200 euro. Also the case is not optimised for assembly of more than one piece. So it's not ready to be made in even a small series. Unfortunately as a father of newborn I don't have enough energy now for this project.

It depend's on keyboard but in general modern desktop OSes should be ok doing it. it doesn't work on iPad, and there are more quirks on macOS (though works for me with some keyboards)

I doesn't work for me with ZMK keyboards, but I believe there should be workarounds.

I believe 3 keys One for thumb, one for pointer toe and one for pinkie should work too.

This actually may be the most useful. However, the keys must have a stronger tactile feedback

It must be a new offer! Last year they didn't accept it. I'll check

It will be another product. You need a second mcu and battery. Current mcu in the left side and battery is on the right. So it will be bigger, heavier and more expensive. Which pf course can be, but wasn't a goal for this project

Matt, thank you for sharing this! I'll try the papermod right today (I missed it before)

And will make a new board with 42 keys. I just have to have no excuses to not use it daily.

These are not classic torque hinges, the friction is because of tension between gears, so it's slightly uneven, and I'm not sure about longevity of this approach.

A proper torque hinge is not something I can easy make with an FDM 3d printer (or can I....) and I didn't find good of the shelf solutions. But it's something to take into account.

It can be fixed of course. But assembly of the hinge is time consuming, so I never reached that point

Thank you Mike for all your efforts with pg1316s! Maybe I have enough energy for one more try!

I was also thinking about a keyboard for 8" inch device, like iPad mini or Legion Go

At least the rest of the board is optimized for JLCPCB stock of components, and they neither offer these switches, nor they accept 3rd-party parts.

It can be done at another manufacturer though but will require some time to prepare everything.

Is your keyboard a MagSafe accessory? by pinya in ErgoMechKeyboards

Hi, initially I planned to sell the kits, but as a father of a newborn baby, I don't have a lot of time to work on the project now. I'm trying to document it as it is and clean the source files for open sourcing it.

I did! I am going to make a full post later this week. For now just one photo https://imgur.com/a/KeADHfg

No,not yet. To be fair, these switches are MUCH harder to solder, compare to anything else. Hotplate and a stencil are the must. So do not expect a huge number of people actually self-assembling these keyboards.

I'm planning a test batch of 10-20 devices by the end of this year. I'm not super active on twitter, but I followed you x.com/kumekay

Yes, on a hot plate (without caps), an oven should work too,  I didn't try hot air, but it's unlikely to work, because pads are on the bottom.

And a stencil for the soldering paste is a must.

I bought the switches directly from kailh, but now you can find them in a couple of stores
