It was created as part of my final project for the Design and Technology Major Studio class at Parsons The New School for Design.
Step 1: Collect Materials
Paper towel holder (preferably metal)
12 Aluminum bobbins (NOT steel)
Magnet Wire (lots of it, the thinner the gauge the better -- try for 36 gauge)
8 strong magnets (rare earth preferred)
a wine cork
and these electronics:
- 6 schottky diodes (1N5822)
- Large capacitor, pref, super cap
Step 2: Cut the Pringles Can
Step 3: Mark out the CDs
If you choose to mark you own guides, I found the transparent "CD" that comes with some CD-R spindles was helpful to use as a template.
