Girlfriend's friend's parents had this tortoise appear in there yard. I have adopted it and am gonna build it a fancy house.

Nothing that fancy actually :D

Plans so far are essentially a wooden box with a door flap and window.

I would like to automate a heat source and light as well as having a webcam for monitoring.

I have a RaspPi B kicking around. Figure I'll get a Pi Cam and have it trigger some solid state relays for heat and light.
