Leo, a Technokinesis user.

Certain aspects of technokinesis are depended on Electrokinesis as machines run on electricity.

The Heroes of Olympus

The Lost Hero

Leo Valdez, a son of Hephaestus, shows the ability to know how things work instantly. He manages to fix the bronze dragon Festus, with no prior knowledge of how it worked and even added a pair of wings. He later builds a small device that he wasn't sure what it did as he built it when he wasn't paying attention. The device was later discovered to be able to operate machines automatically. Leo was also able to fly a helicopter just by touching the controls. 

The House of Hades

Piper McLean, daughter of Aphrodite, wakes the bronze dragon masthead Festus, with charmspeak when Khione confronts her. It is said that Festus seems more alive after she woke him up.
