Chamberlain Garage Monitor repair

As usual I love to go exploring in flea market/antique malls.
Last time I did find a new Chamberlain Garage Control. 
Of course the unit ended up in the flea market because not working.

Pokit

Long long time without writing something, I guess I'm really busy :)
However something happens in my world.

A couple of years ago I did find an interesting Kickstarter project and I decided to participate, Pokit.

It took forever to receive finally the product but in the end, finally arrived !
Few notes about it.
