Boom created by this new electronic device (7)
I believe the answer is:
machine
'device' is the definition.
(machine is a kind of device)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for machine that I've seen before include "Nice ham (anag.)" , "Contraption" , "Automaton" , "See 12" , "Device providing energy to perform a task" .)
