While waiting for the prototypes, i noticed someting.
Going to the about page on Hackaday, there are two versions of the logo.

And the Hackaday.io one is golden.
You know what else is golden?

ENIG !

So i did some changes to the design and circuit. Most notable:

I played around with the coloring and made a full ENIG fill.
Getting this on a black PCB will probably look amazing.

Other changes are:
- Backlight changed to reverse mounted LED´s in the eyes
- Changed 0805 Resistors to 0603
- Added some solder on jumpers to add functionality when the header is removed
- Bigger coil to get the space inside the eyes
- Added a solder spot on the back for the possibility to use as a pin ; )

Will it work with a copper plane inside the antenna?
I have no idea.
But thats the fun part  :D
