Tom shared his prototyping cape for the BeagleBone/Black in the project log forum:
I spun a prototyping cape for the BeagleBone/Black.
The design is derived from the LGX Proto Cape created by Alexander Hiam for LGX / Logic Supply and released under Creative Commons Attribution 3.0 Unported License. I removed the SMD component footprints, which seemed superfluous to me, and cut back the “wings” on the side to make the cape shorter.
