Mack Academy Weblog

Eric recently completed building a computer-controlled calliope powered by, of all things, our Oreck XL vacuum cleaner.

Eric and the gilrs brought the calliope down to the Lilac Festival to share with folks at the festival. It ws a big hit.

This video clip is a treat. Eric has completed building his computer-controlled calliope powered by his 8 lb Oreck XL vacuum cleaner. The video clip is in RealMedia format and you can watch it by clicking on the link below. During the video, be sure to watch for the Mack sisters, our American Bear, the vacuum cleaner (which you can hear in the background) and the laptop computer that controls the entire performance.
