Hacking Fire TV Stick for other uses

[Sizzlechest]

I'm trying to create my own solution for a wifi controlled relay since most of the ones I'm finding cost over $100. The Fire TV Stick is only $40, but the only output is HDMI. Does anyone know if there are any ports available inside that I could use to control a relay? Are there any other small wifi enabled android (or other) devices that might be easier to hack?

Raspberry Pi?

Like Michealtbh said the Raspberry Pi would also be my first choice. Several GPIOs are avaible which can be even accessed via bash shell. There is also a GPIO tool called WiringPI which should make things easier. I think for programming the appilication the Pi is even more open than the Fire TV.
100$ sounds much for we for a ready-to-go wireless relais. Probably you could look also for a AVR or Arduino solution instead.

Arduino Nano is low-cost leader for now. The last one I bought from Amazon was under $7, IIRC.
