Free GPIO pins? about badgy HOT 3 OPEN

GPIO9 is used by the ESP-12 for internal flash memory, so using it will cause resets. You can sacrifice the direction pins to use as GPIO, but note that GPIO1,3 are shared with TX/RX, so serial cannot be used concurrently with these pins. GPIO10 is also input only, so it cannot act as output.

Curious if you went anywhere with this, I'd also like to add a temp sensor.
