Introduction: Jacobs Ladder

I love my neighbor’s garbage I call it the parts department. In this, instructible I am building a Jacobs Ladder out of an oil burning furnace ignition. Play the AVI to see it in action.

Step 1: The Parts and Tool

Ignition transformer
Screwdriver
Power Cord
2 Crimpons
Coat hanger or wire
Pare of pliers

Step 2: Ignition Transformer

Ignition transformer runs on 120 volts 60 cycle 2.1 amp
And puts out 10,000 volts 23 ma.

Step 3: Assembly

Open the Ignition transformer and install the power cord with the two crimpons and test.

Step 4: Make the Probes

Bend the coat hanger or wire to shape and adjust so it arks. Remember this is powerful enough to kill so adjust the probes with the power off and unplug it.

I have found that the improved jacob ladder works a lot better than before since I have replaced the tape that anchors the copper strips with bricks. Thus the problem with the heat changing the position and stopping the flow of plasma no longer happens. Here is another video taken this time in the dark.

Here is a video on an improved copper stripling jacob ladder approx 0.2 mm apart. The distance is important since 160 W of power is barely enough. Like I said a fan blows air which provides oxygen enhancing the arc.

As you can see the jacob ladder climb very fast thus i call it Ultra fast jacob ladder.

I made a small jacob ladder with copper striplings and they were separated by 0.5 mm distance. The voltage was 8 kV and 20 ma at 25 KHzs.

Did you make an Instructable on it.

There are so many ways to make a Jacobs Ladder.

No but I did use the safety and other stuff and looked at the other instructables before I build it. Mine with wind (from a fan) can give 5-6 cm plasma gaps.

Nice
