:. Project / Motor Tower

I had just started working on some parallel port interface data, so I decided to make up this project.  It's a pretty simple interaction between some software and low level hardware.  I created a k'nex tower to raise a flag as a physical indication that I received an e-mail and then lower the flag when the e-mail was checked.

I took a (really shitty, low quality) video of the device in action as I was testing the motor controls.  You can barely make out the wheel  moving/stopping.  The wheel was driven by a piece of yarn, kept tense at the top and driven by a 3.3V motor at the base of the tower.

Later I used the base of this code to control more complex projects like my armcam.
