most all can be done with wire cutters and knife, very little soldering
for pump. depending on which approach you take 'coming out' of computer.

there are 'card adapters' that plug eisa and pci. in/output is from
8 to 24, then you can get 32 to 64.

some cards a fixed input / output. some are command programmable.

control is; 'switched voltage', 'dry contact', 'analog voltage' in/output.

variable speed control for pump can be done several ways.

as stated before, 'are you good enough'?

can you write simple 'c'? scripts?
