Regarding the pump, the peristaltic one I looked at is rocking a speedy 100ml/min. This means I’d be getting a brain melting bottle every three to four minutes.
So, idea next! Fill height sensing is a must, but, rather than a pump, use a motor as the valve. Just need to build a filling jig. Take a cork or bottle cap or whatever, mount… a solenoid, yeah, a solenoid to pinch the silicone tubing. Have the distance sensor grab the range to the cider. Feed the range to an Arduino, or whatever, when the height hits, kill the flow.
I also want an autoloader. Thinking like an autocannon.
