Hello everyone, I hope I have found the right place to my question. I need help identifying pieces in this construction and also help constructing this. A year ago I was in a motor vehicle accident and broke my neck. I lost the use of my fingers and below my chest making playing video games extremely difficult. Adaptive controllers are extremely expensive and do not provide many options that are suited for what I need. The controller is made with Lego pieces making this design probably be the cheapest. However he provides no piece list or how to construct it. Hopefully some of the experts here can help me the video as follows:

Surely one of the buildes on here can figure this out.

really want to help, will work on it this weekend and see what I can come up with. will pm you 

Thanks! Greatly appreciated!
