Hans, a maker from Trondheim, Norway, sent us a link to this Wimshurst Influence Machine he bought. He asked about the history of the device from the seller and found out that it was used in a grade school, from 1911 to 1951, and was owned by the principal. Nice job on the restoration:

The original disks on the machine were too warped and worn to be successfully restored. All the sectors were also missing from the disks. I acquired a large 3 mm thick bakelite sheet from a local plastics supplier and used this as a base material for cutting out a pair of new disks. The disks were then painted with black acrylic paint and sectors of aluminoum tape were then added to the disks.

In Volume 17, MAKE goes really old school with the Lost Knowledge issue, featuring projects and articles covering the steampunk scene — makers creating their own alternative Victorian world through modified computers, phones, cars, costumes, and other fantastic creations. Projects include an elegant Wimshurst Influence Machine (an electrostatic generator built entirely from Home Depot parts), a Florence Siphon coffee brewer, and a teacup-powered Stirling engine. This special section also covers watchmaking, letterpress printing, the early multimedia art of William Blake, and other wondrous and lost (or fading) pre-20th-century technologies.
