Eight Years of Farming; Is EveryboArDy Happy?
summary
Board farm grows from six to about fourteen boards on a grounded metal rack, powered by one PC power supply with the 5V standby feeding two BeagleBone Black controllers and ACME power capes; custom TNC boards (Tiny MCU modules) add power switching, opto-isolators and UART translation but hit USB CDC ACM endpoint limits so firmware emulates MOXA multiplexed serial to get more virtual consoles. Remote sharing uses per-board user accounts, SSH authorized_keys, a shell-based config exposing commands like console, power, reset, rsync with locking and overlayfs per-user roots.
