In practice, most devices require some form of energy storage buffer between the harvester and the device, if only to smooth out the overall power curve and provide somewhat more predictable operation. text/html 2026-03-25T13:38:32+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.cicada-hub.org/tutorials:checkpointing_overview?rev=1774445912&do=diff Checkpointing Overview Reckoning with inconsistent and unpredictable power is one the major challenges of intermittent systems. Conventional programming and hardware architecture assumes consistent power supply largely as a given, and so intermittent programmers and designers must often determine and implement a method to mitigate power failure as part of their overall design. text/html 2024-10-30T15:34:24+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.cicada-hub.org/tutorials:common_board_components?rev=1730302464&do=diff Common board components Common things that seem to show up on most any board you make.
