Double piston extender tileable one-side-powered v1.1

Hello guys,
Today I show you a new type of tileable double piston extender.
I know, there's lots of them on the Internet, but I've never seen my concept before.
The difference with the others is the fact, that mine is only on one side of the pistons, so you can stick 2 modules together, and repeat it as many times as you want (to understand it more easily, you should look at the pictures).
I made the version 1.1 in 1.6 PR.
I don't think you need a tutorial, nothing is hidden.
Sorry for my english, I'm french.
