As i mentioned in my last self watering post my youngest had to create and maintain a vege garden for a school project.
Attached are a few pics of before and after, it’s a pity i didn’t take a pic of the garden in it’s initial super feral state as the grass was about 4 foot high!
The little munchkin with his mothers help cleared, dug, planted, weeded and finally placed paving stones and bark to produce a sweet little garden. Not bad for a little pip squeak who weighs about 28kg dripping wet.
Then daddy couldn’t help himself so added BLE enabled irrigation for watering so he can enjoy a cheeky beer instead of holding the garden hose 
So it’s NETMF 4.4 running on a STM32F411 powered via 12v which also powers the 12v water solenoids using high side switches controlled via BLE and a Win10 Phone app.
Works a treat but next week it will get pimped even more with WiFi and sensor data to the cloud :
