HID VS torn

I don't think the built-in keyboard library identifies itself as "boot capable" in the HID descriptor, which is necessary for simpler keyboard devices. Try using NicoHood's HID library with the "BootKeyboard" object.

Looks great! How did you handle the programming? Did you follow a guide, or did you implement the Arduino HID Project library?

Skip the esp then and pick up any dev board supported by the HID project.

You can make it act like a HID - which is what I assume many people have done - with custom drivers like this one. https://github.com/NicoHood/HID

You can use Arduino HID Project which allows to reprogram atmega16u2 which performs USB communications on Uno. Then you can upload HID sketch on 16u2 and "normal" code on atmega328 which would do everything and send desired wheel state via serial. On 16u2 side you will parse that serial command from 328 and translate it into HID message

I'm trying to grab the "microphone muted" LED status from the HID library, but it seems like the library only supports a select few statuses out of the box: https://github.com/NicoHood/HID/issues/151

https://github.com/NicoHood/HID for a real UNO

Nano (atmega328) doesnt have native USB support (just a USB to UART converter). UNO also doesnt have native USB support, but has a atmega16U2 on board. You can flash this chip and build a USB HID bridge -> https://github.com/NicoHood/HID/

Try using NicoHood's HID project and the system key page: https://github.com/NicoHood/HID/blob/master/examples/System/System.ino

There are other benefits: A PCB design can be shared so that others can fabricate it themselves. (Or modify it if they wish). A PCB design will likely have a schematic, too, which can be studied.

I'd also bet that PCB projects are more likely to inspire better PCB projects. -- Or at least, the domain I've tried my hand at has been PCBs for custom mechanical keyboards.

e.g. I've seen boards inspired by https://github.com/hsgw/plaid such as https://github.com/coseyfannitutti/discipline or https://github.com/rtitmuss/torn and I think there are several popular split keyboard designs which basically descend from https://github.com/MakotoKurauchi/helix

Torn

I'm going to build the Torn ergo split keyboard but I don't need x5 PCBs, switch plates, and base plates. So I'm checking to see if others are interested in splitting the cost of the JLCPCB order. For clarity, I'm not looking to profit from this, just split the cost of the PCBs.

https://github.com/rtitmuss/torn Seems to be all freely available including a build guide

I would like to compare it to Torn

For a true match, the keyboard should be a Torn

Also very much interested in this. I'm thinking about building a split keyboard myself and can't decide on which one to go for. I've considered so far: - redox: The layout looks thought through - sofle: Easy to build, because of the used microcontroller - torn: Is throughhole, huge plus for me since I could order pcb's and solder it myself, also looks good. the only thing I don't like about it, is that I need a number row and am not sure if I'll be able to add it to the schematic

The torn is the closest https://github.com/rtitmuss/torn

I also have an ergodox ez, and want a smaller keyboard for carrying it to the office and on travels. I'll go for Torn (https://github.com/rtitmuss/torn) eventually, it will be available on splitkb.com Regarding tenting, it does have a slot to screw in a tripod like https://splitkb.com/products/manfrotto-pocket-tripod
