Jacob's Ladder 3D Printed - Desktop 2 X AA

https://youtu.be/HNDkIMzz2wo First off, a word of warning! This is a high-frequency, high-voltage device, so keep it away from all electronic equipment - especially pacemakers! I've even gotten shocked while working with capacitors and had my USB keyboard go out because it was too close to the running coil. That's from a 3V input power source, by the way! So be careful. This is essentially an add-on to my original Tesla Coil 3D Printed - Desktop 2 x AA post from last April (https://www.thingiverse.com/thing:2855880). I've created a 3D printed replacement top that lets you transform the original door knob style toroid into a Jacob's Ladder electrode mount. The cap was designed to make it easy to install two insulated 12-gauge wires, one at either end of the secondary coil. This creates a mini desktop Jacob's Ladder using the same design as my original Tesla coil. I've attached a video of the ladder in low light conditions. Check out my keyboard num-lock light, which is right next to the running coil. These devices aren't on the same circuit, but placing the Jacob's Ladder within a foot of a digital circuit seems to cause some interference with the keyboard. The cap has two holes on top. The first goes through to the underside and uses a 6-32 screw to secure the 12G wire and connect it to the secondary coil output wire. The second hole goes through to the side, where a longer 12G wire is connected down to the base terminal of the secondary coil. There are holes for two 6-32 set screws on either side that will secure both wires in place. It seems like this coil's pulse rate isn't sufficient to produce the long, slow arcs we're used to seeing. Instead, it's producing lots of short arcs that sporadically run up the length of the electrodes. I'm still happy with the result, though - this turned out to be one of the smallest and lowest-voltage Jacob's Ladder examples I've seen so far. Hope you guys enjoy!
