gadgeteer

I'm a little stuck... Click here to teach me more about this clue!

'love contraptions' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for gadgeteer that I've seen before include "Gismo buff" , "Perhaps mobile fan" .)

I've seen this clue in The Sunday Times and The Times.
