Afternoon all! I sell a bit of veg, but not enough to warrant massive spending. I'd like to make an automatic weighing machine with an old potato bagger. In effect it'll be a ~ .55kw motor running an elevator into a hopper I will manufacture that will be on a weigh cell. When the predetermined weight is reached (2kg) the controller will tell the motor to stop. I empty hopper and the motor restarts, or I press a button to restart the cycle. So basically- are there any of that kind of controller available off the shelf, or will I have to design one?
