Rain barrels are a great way to reduce water uptake, particularly in times of drought or where rain is infrequent. But, getting that water to where it is needed may require work, especially if the need is higher than the barrel. This simple circuit combines a PV pulse charger with protection circuitry for the battery and a pump to efficiently get the water where it is needed. It uses widely available 12V/10W PV panels, 12V LFP or LA batteries, and dual 12V 800 LPH pumps. It can easily be scaled to support larger loads and/or add more advanced features like timed watering schedules.
Watched "River" (https://imdb.com/title/tt14222534/), at Finsbury Park Picturehouse. Phenomenal drone photography and a great score. Really a great spectacle in every direction!
It's also so cool to be able to walk right home from the cinema... 🍿
I first put this together last November, but couldn't make it sound "together". Around Christmas Arturia gave away copies of their Tape MELLO-FI, which I used to give a more lo-fi vibe, and decided I like the sound. #dailies
