The Tengoku is a 28-key split keyboard designed and shared by Dane Lipscombe aka dlip/fata1err0r81. A handwired board featuring dual trackpads and contoured housing made using the Cosmos Keyboard Generator.
After using my Tenshi keyboard for a while, I settled on only using the top 2 thumb keys. My layout uses the thumb a lot and it was becoming uncomfortable to hit with the side so much, so I wanted an angled thumb cluster so it would use the more of the padded part. My Tamatama keyboard fulfills this requirement, but I also wanted it to be lower profile since I decided I don't like hovering my hands, and for it to be more portable than trackballs – Dane.
