Who needs wireless when you can run I2C over 50 feet?

The way I wired it is

Solid Blue - SCL

Solid Green - SDA

Solid Orange - VCC

Solid Brown - GND

All stripes - GND

My theory is that the twisted pair wiring which prevents cross-talk in Ethernet will do the same for I2C. It works for me.

The objective of this is to move the keypad and new display to a handheld enclosure that can either be hooked inside the Dalek or operated outside. The enclosure has room for more electronics - I already included a rotation sensor - so full external control may be possible in future.
