Hard Disk Generator

This one of the smaller piles of Hard Disks that I receive a couple of times per year.
My 2 main sources are a local computer recycler that has saved me upwards of 200 drives in a single load, and a pair of chums that work in the I.T. Sector and save me what ever goes bad on their network.
This load represents about 2 weeks of evenings stripping down the drives and sorting the scrap into various piles. The Aluminum frames are recovered for the foundry and are an excellent stock as they flow nicely and are easy to machine. The yellow bucket of "Platter Hub Motors" needs to be melted twice, once to reduce the Alum from the internal metallic parts, and the second time for what ever project is underway.

Mike won because in the end, it would be easier to build with angle iron. Detail...

Constructable CD Sculpture

At the invitation of Prof. Susan Gerofsky, I visited The University of British Columbia (UBC) as artist-in-residence for a week during January 2007. The agreed-upon project was for me to develop a mathematical sculpture that can be replicated in classrooms. I worked with Susan, student teachers in UBC's education program, and visiting students from Vancouver-area schools to test the ideas and write up a lesson plan. In addition I left one example on display, as a reference model Detail...
