Ok, it's been long enough lets see see this in action! First I have a short video just showing the coils acting as a solenoid and then in a stepper motor configuration being controlled with only buttons to prevent this project from being to complicated or expensive to start.
and next we have the same stepper motor configuration being controlled from a laptop talking to the Arduino from a chrome extension installed locally available for this project in the GitHub repository. The code is still pretty early on but can give a feeling for where it is heading overall.
There is code supporting the solenoid and speaker to some extent so far and work is still being done all around on the code. I believe the design for the coils is pretty stable from here out though I am experimenting with a removable ferrous core potentially utilizing a large set screw.
