We refill these bottles MANUALLY at a community centre I volunteer at some weekends. They’re a PAIN.
If I wanted to use one of my Photons to begin building a DIY version of the electronic system in the picture anyone know how I’d begin? Like what sort of pump? Peristaltic or diaphragm or a third (better) type?
Also how you’d measure out a dose? Can some pumps handle the measuring or are you always going to be looking at a scale?
