Good.

Success = Effort x (tools)^2

Success = 1 x (1)^2 at the moment.

I'm waiting on the cubie expansion boards one of which
i plan for this LCD. Have to wire a duplicate fpc + power supplies (3.3V
+ 18V backlight). That means 5V and 19V laptop type power supply needed
to power up the LCD.

So yes if I spend time to make 2nd tool with cubie, then its time well
spent as I will have 2 tools, and if I make a duplicate eoma one, I can
send one tool to you for parallel effort.

Option1 - Success = 1 x (2)^2 + 1 x (1)^2 = 5

If just send you the eoma tool after having made a cubie tool for
myself, it would become

Option2 - Success =  1 x (1)^2 + 1 x (1)^2  = 2

If I make a cubieboard LCD system tool for you as well and the eoma
tool, and you can use both effectively, then we both have 2 tools and it
become

Option3 - Success = 1 x (2)^2 + 1 x (2)^2 = 8


Take your pick!
