Just wrapped up a new adaptive Xbox controller build for my son. Not much changed in the fourth version, I've tightened up the button layout and lowered the sticks to make it smaller and closer for my son to use his feet. He also requested it be painted red again but this time, he wanted some nuclear bombs on it. Besides that, everything else is the same from my last build that was two years ago. The V3 build held up very well, my son used it a lot and we didn't have any problems. He's been getting better at using both feet together. For his birthday earlier this week, he got a Xbox gift card and purchased 7 Days To Die. One of my favorite games, he's been interested in it and he's doing very well playing it. I'm excited for him to continue his growth and be able to share more challenging games with him. He's come a long way since the first build!
For info on how to build this adaptive controller, read my post here. Feel free to contact me for for any questions, I'd love to help.
