I'm not getting a w1_slave, and all I'm getting is 00-xx0000 when the DS18B20 isn't burning my fingertip. I went for green for ground, which is on the top right plug from this perspective. I spliced some mobo power cables to come Cat6 for the sake of a throwaway breadbording. The white and red plugged into the pi board is spliced to the orange & O/W that's on the breadboard.
This is my first attempt at doing any wiring anything with a Pi that isn't just "ping & wol" or something similar. Any tips welcome.
