Hello I am new to computer interfaces and i need something which i can drive
at least 29 devices via relay. No inputs with this though. Nothing fancy
just either on or off. What hardware would i need to do this? what kind of
price range are we talking? Thanks in advance

Boondog have a board that can be configured to have 24 digital outputs.
You could install 2 of them in your pc.
