I had an arduino and a raspberry pi and I just needed a project to get me going on learning how to use them. After a family member suggested a robotic potato cannon I got building. It took nearly 9-months to get where I am now, it works mostly how you would expect it to, but there's always room for improvement. I didn't document this as I built it, so information about the build is somewhat sparse.
