I doubt that it'd be possible to offer a wireless UHK under $300 if we insisted to our current features and quality standards. The market is limited, it's a huge R&D effort for a small company, and a large company couldn't care less for a niche product like this.
Have you considered adding it to the FAQ? I feel this is a thing many are curious about.
curious about your use case. Would 3 meters of cable help?
I've been wanting to have half a keyboard just below each of my pockets. Maybe with some kind of thigh-holster kind of thing.
So two wireless halves would work, but have a longer cable would also make this possible. I plan to be sitting / lounging when using, not walking, so could be possible.
I think that would be the most comfortable position for typing for me, and keep it fast and for long periods. Hoping to combine with a zero G chair from relax the back store kind of thing and monitors on swing arms up above a bit.
Now to think more seriously about the size, this could work.
My first thought is that if they were two wireless pieces, then timing of the receiver could be an issue and it could see key strokes in the wrong order(?)
I guess power is also a thing. Perhaps it would require two usb sticks a receivers?
I've been keeping an eye on these discussions for some time and seeing some that are so close to my vision of a perfect design, the wire in between the two pieces limits one of my use cases.
Noticed mention in the thread about "Let's Split" - a quick search shows some pics that appear to show some without a wire between them, so maybe it's an easily solved issue, or could be trick photography hiding the in between wiring(?)
Glad to see more and more people working on better keyboard layouts!
