This hour, Vaughn talks with Brian Kitchen, the winner of the Supreme ASB Bright Sparks award at only 13. His very first invention Xtionberry Pi is a 3D scanner for mapping caves.

As well as winning the trophy for the Bright Sparks award, he won $1,400 from ASB to spend on his upcoming endeavors.

Brian is into flying drones and hopes his next invention can include some, describing his "Xtionberry Pi" as having a box for its batteries, a keyboard, some 'electronic bits' and a tiny computer.

What is his invention scanning the caves for?... what are Lava caves?

Brian explains how he wants to get into science and technology after High School, and tells us exactly what is a Rasberry Pi...

Listen to the full interview with Brian above.

Vaughn talks with Hazel Phillips for Apps of the Week, discussing bagoffarts.com, OK Google, a website to help you get cheap fuel, and more!

Hazel is back from her walk on the Milford Track (where drones aren't allowed!) and ready to talk all the apps and social media with Vaughn.

What does 'Vodafone' actually stand for? Vaughn explains.

The Text Message turns 25 today in New Zealand- and the very first text sent said "Merry Christmas!"

Hazel lets us know about shut up and take my money.com, bag of farts.com and joinhoney.com... very weird titles but what do these websites actually do?!

Also, shitexpress.com which Vaughn explains sends "actual poo", and an app that can actually help you find the cheapest place to get feul.

For all this and more, listen to the full interview with Hazel above.
