Right! I’ve finally got round to ordering some #attiny45v which should run at 1.8V, means I can start work on my plans for a simple modular mini solar powered controller (e.g. water pumps, irrigation and other garden devices).
I’ve concluded that if I can get these working and they are nice and modular it’s one of the most #solarpunk things I can contribute.
