At least for this year 8 should do. In my wildest dreams
I can't imagine using more than 16. But I would be happy
with 8.

That gets me a bunch of parallel outputs. Good for
controlling valves. But I need to control 24V. To
satisfy Corvallis that it is safe, the most straightforward
is to use relays between the computer and the valves.
Do you know of a suitable relay board?
Input control: 3V-5V
Output control: 24V @ 1A or more
