Heatwave Heatwave is a 36-key wireless, curved unibody split keyboard by dohn-joh – with integrated lever keycaps.
KBD.news Published July 7, 2025
After releasing projects like the Alias or Leveret – both with lever keycaps –, dohn-joh shared the files of his Heatwave . This unibody split keyboard features a curved alpha stagger , which reminds me of the Willow layout.
It's difficult to give an exact cost because this build took a lot of prototyping. […] I also bought some parts during the height of US tariffs, so they may be cheaper for you depending on your location – dohn-joh.
In the photos, the Heatwave is built with the author's new swell keycaps – a sculpted keycap set inspired by Pseudoku's DES profile.
