Can’t find a neon sign transformer? Need to fabricate your most memorable Tesla Coil without confronting the intricacies of going strong state? Here is some uplifting news: Vacuum tube Tesla Coils, which have been getting back in the game as of late, can be similarly pretty much as remunerating as some other kind of loop without burning through every last dollar. This is one such loop that I worked throughout the spring of my eighth grade year.
While this task takes care of business in its ongoing structure, I have recognized a few issues and attempting to fix them. You would best be encouraged to defer your structure up to that point – it appears to be that postulations cylinders could work all the more proficiently at higher frequencies and my essential RLC tank circuit’s normal recurrence is a lot higher than my optional side RLC circuit’s regular recurrence; another optional loop with a recurrence of roughly 1.5MHz is being planned and the essential circuit will be retuned. I anticipate an extraordinary jump in execution, with flashes conceivably up to 7″ to 9″.
3/10/10: I chose to attempt to assess the full frequencies of my essential and optional circuits utilizing deepfriedneon’s recipes, and I observed that my curl is swaying around 100kHz over my essential circuit. I have no parts to fix this currently, however will add a capacitor or two to the essential circuit to bring down its recurrence soon. Significant: I found a 6.3V at 12A Hammond power transformer and supplanted my 5V PC power supply – the outcomes were genuinely great; I am getting preferable execution with one cylinder over I at any point got with two, fiber voltage truly matters! Here is a speedy video:
4/16/10: The MOT (plate transformer) wore out in light of the fact that the optional windings were harmed by past analyses (SGTC,s, Jacob’s Ladders, and so forth.). It was supplanted with a bigger one and the sparkles are currently very nearly 7″ long – this curl proceeds as well as Steve’s did, however with only one cylinder and with an inadequately tuned essential oscillator!
In the mid 21st 100 years, a large number of us have never at any point known about vacuum tubes, and the rare sorts of people who have just realize that they were utilized in old hardware. Subsequently, before I start this venture, I want to make sense of how they work.
Lets investigate picture 1. This is the standard image for a vacuum tube diode. A diode just leads power in one bearing. They can be utilized to transform a substituting current into an immediate current. In the graph, the base half hexagon is the fiber. It is very much like the fiber within a brilliant light. The line above it is known as the plate. The circle around the fiber and plate addresses the (normally glass, at times metal) envelope of the cylinder. Practically all of the air within this envelope has been emptied, there is a vacuum. This will become significant later.
Presently, lets investigate picture 2. Here we have applied a voltage between the fiber and the plate. The fiber is adversely charged, and the plate is decidedly charged. While the electrons in the fiber are drawn to the plate, there isn’t sufficient voltage for them to do as such all alone. So how might we inspire them to hop? Investigate picture 3.
In picture 3, a couple of new things have appeared.First, we have a 10 volt power supply associated with each side of the fiber. Similarly as in a glowing light, this warms the fiber up. The negative side of the power supply is as yet associated with the fiber, yet the positive side isn’t. Notice that now, the adversely charged electrons are stil streaming into the fiber from the 100 volt power supply, yet something is unique. For what reason would they say they are drifting around the fiber? As the fiber warms up, thermionic outflows happen. Basically, the electrons are shaken off of the fiber by its nuclear power. This can happen in light of the fact that there is a vacuum. So presently, the inquiry is: What happens when we interface the positive side of the 100 volt power supply to the plate? Investigate picture 4 to find out.
In picture 4, the positive side of the 100 volt power supply is associated with the plate. We have zoomed back towards the cylinder. In the image, the electrons drifting around the fiber are moving towards the plate! There are no air particles to prevent their entry, so after the thermionic outflow happens, the emphatically charged plate draws in them, and they advance quickly towards it, hit it, and move along the wire once more into the power supply. That is the manner by which a vacuum tube diode works.
The standard of activity is somewhat straightforward, however a Tesla Coil, for example, the one that we are building is an oscillator. That truly intends that there is an input framework that turns the diode on and off, to achieve this, we utilize a triode. Peruse on the figure out how it functions.
