In 2008 I combined some parts to avoid constantly forgetting to water the two Bananas in the living room.
This is just a timer switch, powering a cheap pump for indoor fountains – 1 minute every two days was enough to deliver about 400 ml of water from the reservoir (can). The (pneumatic) tube has an inner diameter of 4mm and an outer of 6mm.
If you don’t trust the timer to switch off in ANY case (or your configuring skills) this can still be useful when you are on holiday and everything lies in the bathtub. 😉
And of course you cannot have this lying around if a toddler is in the area… ^^
This year we could finally eat some fruit BTW:
