I live in a beautiful part of the world surrounded by coastline and lots of rivers (Christchurch, NZ). I have a 2 person Kayak that I occasionally take out with my kids and wife but we’re somewhat limited in range by our muscle power. I’m starting to investigate supplementing my muscle power with a brushless electric motor powered by a lithium battery and controlled and kept safe by an Arduino programmed with 12Blocks. Here’s a photo of some of the components.
Here’s a video of the KayakJet jetting around!
