Today we devised a way to (hopefully) raise the marbles from the bottom of the track to the top using a servo motor. It is rather obvious at this point that we did not plan our initial track high enough and the end of it is too low. Oh well, version 1 is usually that way, right?
Here is an update to the marble roller project. We are using foam board and hot glue for construction. This is a surprisingly strong construction method for prototyping and projects like this.
In the foreground is a new stepper motor. Not sure if we will be using it or not for this project yet.
