====== NRF-Nunchuk ======

A custom wii nunchuk remote control with telemetry info display

======= Idea =======

Its nice to drive around a Matecrate or Couchelement, but the need to stop everytime you want your battery level is kind of a let down...

So starting out with a wired Wii Nunchuk was ok and the upgrade to an wireless nunchuk clone was nice (people like to pull on cables...).

But a wireless controller with a small display that shows (live) telemetry data and maybe even allows to make some small changes to the vehicle parameter,
that would be a really nice upgrade.

======= Thumbstick - exchange the default thumbstick =======


Ok so lets start with the first hardware "mod", the exchange of the default thumbstick for a playstation like joystick with pushbutton.
