One young student may have come up with a solution to monitoring water charges at the BT Young Scientists Exhibition in the RDS.

Aaron Speer (15) from St Andrew's College in Booterstown, has invented a device on a water meter that sends a signal to a laptop. This in turn tells a householder how much water they are using.

The system uses a network called Sigfox which sends data from the meter reading device to the web interface, and its sleek design makes it extremely easy to read.

Aaron has already been approached by people in the water industry to look into using his remarkable design.

Another invention which could change people's lives is the Virtual Music Maker by two Antrim girls from St Killian's College.

Anna Erwings (13) and Meabh McIlwaine (14) have created a musical instrument that helps "disabled people to easily play instruments".

The instrument plays music by pressing buttons and moving a Wii Remote connected via Bluetooth to a miniature computer.

The device can have "as many instruments as possible" on the various buttons and is easy to use while sitting down.

"We've tried it out and everyone who used it absolutely loved it," Anna said.

Two teenagers from Monaghan also made inroads in healthcare for the elderly.

Caolan Maguire (16) and Shane Gilbride (17) from Beech Hill College developed an "inexpensive mobile device to help the elderly".


The device helps people send data about their health to their GP automatically and helps turn off home appliances with an easy-to-use app. "One of the main attractions will be the affordability, it only cost me €20," Caolan said.

President Michael D Higgins said there was an "astonishing variety and quality" on show.

Mr Higgins also stressed the relationship between arts and science by saying "it would be a great mistake to view science as in any way distant from the imagination of the artist".
