Thank you for the reply!

I followed your directions and I am getting this error:

Code:

Gekko v0.5.14
       I'm gonna make you rich, Bud Fox.


events.js:183
     throw er; // Unhandled 'error' event
     ^

I am willing to format the SD and start over from the beginning if someone can give me a path to success. every tut I follow verbatim gets me into trouble with all kinds of errors. 

Please advise.

No one made a pi image for gekko?
