IT’S often said necessity is the mother of invention.That statement has never been truer in the case of Lily McCauley, a Bendigo teenager who says she’s always looking for the television remote control at her place.So she did something about it – and has entered her nifty remote control tracer in the Bendigo Inventor Awards in the young inventors category.Sixteen-year-old Lily, a Girton Grammar student, credits her younger brother Chad, 12, and sister Esmae, 8, with inspiring her.“My family is insane and everything gets misplaced... helped by little brothers and sisters, but that’s enough said,” she laughed.“I got sick of looking for the remote in the ironing basket or under the couch. When I want to watch TV I just want to flick the remote, I don’t want to have to look for the remote.”Lily said the tracer was very simple. “It’s just a two-piece device. You have one part that’s the sensor and you connect that to the remote and the other part of the main sensor.“That has the button on it and you just click the button and find the remote player and you have a sensor that’s connected.”Entrants in the Bendigo Inventor Awards can share in cash and prizes and get business support and mentoring to bring their invention to commercial reality. The awards ceremony will be held on September 2.Details: www.bendigo.vic.gov.au/inventor or phone 5434 6241.
