You just can’t be a mad scientist without one
LightningPhil just uploaded designs to Thingiverse for a Van de Graaff machine. A Van de Graaff machine is a device for creating an electrostatic charge. We’ve all seen these devices before – they essentially make your hair stand straight up and create lightning. While the details and instructions for actually assembling his designs are still sketchy, this is a very exciting development. 1 As his directions suggest, “A Van de Graaff generator is essentially a box, a tube and a ball with some gubbins that connect it together and move the charge about. A box, tube and ball are easy. With a 3D printer, so are the gubbins.” I can’t wait to see his finished product!
As soon as I saw this I had an idea for how to make use of these designs from some parts to which just about every MakerBot operator has access. 2 If you own a Cupcake CNC you can extend the Z axis threaded rods above the level of the Z drive belt. Most users opt to lower these Z axis threaded rods so that they extend into the lower cavity of the Cupcake, saw off the excess rod, or sometimes leave them extended off the top of the Cupcake and add a Z axis rod topper or Z axis crank.
I would think it very possible to modify your Cupcake to use the top of one or more Z axis rods to act as the drive for a Van de Graaff generator.
3D printing is a lot of fun, but it would be a lot MORE fun with lightning.
