Manual fluid dispenser with discharge measurement

This is a manual fluid dispenser where pushing a lever or similar mechanism not only dispenses fluid but also generates electricity. This electricity powers a communication unit that estimates how much fluid was dispensed and how full the reservoir is, based on the generated energy.

Why it matters: Low-power wireless communication and microcontrollers are now cheap and efficient enough to power from manual motion.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateElectrical generator, communication unit, calibration system
