[chbot] Lego Mindstorms Micro Scout

[Kerry Harpur]

Hi Andrew, I was aware that I can power motors straight of the Pi, as this
is a project for my kids I wanted to make it more hands on for them, so I
was planning on using a Picoborg and they can learn a little about
soldering. Although I think the Ether is telling me to go for Mindstorm as
a working Mindstorm camera come into work this afternoon.
