Over 700 innovations designed by young people have been shown at the CoderDojo Coolest Project Awards in Dublin.

Young innovators aged between seven and 17 developed the gadgets, robots, sites and apps on display at the RDS.

Organiser Noel King said that the event, now in its fifth year, is said to have grown from 19 projects in 2011 to 700 hundred this year.

Over 10,000 people are expected to have attended today's coder showcase, with most participants coming from CoderDojo clubs runs by parents across Ireland but about 100 entries also came from clubs in Europe.

Among the projects was Auto-Journalist - developed by 13-year-old Niamh Scanlon, who was named European Digital Girl of the Year for 2016.

Her innovation helps journalists conduct interviews by sending a list of questions to interviewees, who can then record their answers and reply through the app.

Members of the CoderDojo Warehouse on Dublin's Grand Canal Quay developed a low-cost phone for developing countries that does not require a network, as well as a dementia aid app to help with medication reminders and important contacts.

14-year-old Jake O'Toole developed a personal safety app that shares your location with trusted contacts to let them know where you are if you are feeling unsafe.

"The idea came from my own personal experience with walking home alone in the dark," Jake said, adding that it could also be used to track Alzheimer's patients.

Several international speakers took to the various stages at the RDS to share their knowledge with the young innovators.

The event is aimed at inspiring the next generation of technology entrepreneurs, tech professionals and anyone considering a career in coding.

Clare Dillon Of Microsoft Ireland said it was heart-warming to witness the results of placing technology in the hands of children.

Other organisations supporting Coolest Projects include RTÉ, Aol, Openet, Bank of Ireland, Folens, Symantec, Virgin Media, Deloitte Digital, Salesforce, Dublin City Council and Accenture.
