This is a video of me playing the GH controller. The Song is called Holy Diver. I'm playing it on Hard. It demonstrates that it is working just fine (every part of it).
Note: I hadn't seen an original red octane controller (nor any 3rd party copies) at the time I made this controller, only on pictures.
Feel free to leave a lot of comments about my project, I'd like to have some response, and if you have any questions about anything according to my project, don't hesitate to ask (but please try to ask things that aren't covered in the instructable! Thanx!)!
