30-key wireless topre/ec hummingbird keyboard based on the rufous & topreviung
named after katori senkō mosquito coils that inspired the original conical spring design for topre switches, as well as katori's translation to bird as homage to the hummingbird.
Revision 1 has been built and tested. Had design error fixed in r2 but yet to be officially ordered
Can be hand soldered or ordered assembled using assembly files
