Reid can do hardware, but everything but the most basic of software (and what little he's picked up from Garcia) is totally lost on him. Someone else would probably need to deal with that.

Luckily, Reid has ideas of using Pokemon to their advantage. At the very least, they can make magnets as powerful as they need to be using a high-level electric-type and a high-level ice-type. And steel- and fighting-types (and cannibalized computer parts) should be able to help out with the actual construction.
