I’m very broad so my keyboard is split wide, it comes almost to the end of the cable so having two wireless halves would make a nice difference. The shield looks promising, but with all of my other projects I just lack time to hack together a keyboard.

That would be epic. I asked the Ergodox folks about it and they said they’ve experimented with a wireless Ergodox EZ but there’s problems with latency with the two halves being wireless. So I’m skeptical that they’ll produce anything soon.
