High Voltage
Microwaves parts and microwave transformers have served as a basis for a number of my designs and projects. One function of them is the ability to generate high voltage arcs of plasma. Here are two of my projects showcasing those arcs. Additional uses include electromagnets, welding, and spot welding.
Note: Microwave transformers and their capacitors can be lethal. Proper safety precautions were taken.
Lichtenburg Figures
These figures were created by placing the two outputs of a microwave transformer on opposite ends of a plank of wood. The voltage between the two electrodes is approximately 2200V. A conductive compound was also placed on top of the wood to make it more conductive. Once the transformer is powered on, the electricity burns a path in the wood between the electrodes and forms an organic looking burn pattern.
Jacob's Ladder
The ladder was created by placing the two outputs of a microwave transformer on two conductive rods spaced apart with an increasing gap between them as it reaches the top. Once an arc is formed, the plasma heats up the air above it making it conductive and the arc continues to rise up the two conductive rods as if it is climbing a ladder.
