Tesla Coil 

*cont* They cannot get as big as DRSSTCs can. DRSSTCs are fucking dangerous but cool at the same time. These ones you NEED a faraday suit to touch the arcs or you will die. These things can be HUGE. They are very hard to build because both the primary and secondary coils have to be in resonance with each other. It is a committed build, because it is very expensive to build and even more expensive to buy. Never buy them. Always build them. It's cheaper that way. I spent about 200 dollars total on my SGTC, and for a smaller one online, it costs about 1200 dollars. DRSSTCs cost around 1000 dollars for a big one... to build from scratch. VTTCs are what it says... it has vacuum tubes. Vacuum tubes are archaic transistors. Transistors boost current. VTTCs are slightly more complicated than SSTCs, and their arcs are completely safe to touch. The arcs are still HOT though, but I'm talking electrically. HFSSTCs are high frequency, so they are also safe to touch to an extent. In all of these, I still suggest NOT touching the arcs at all, unless you have a desktop model of an SSTC. Those ones apparently "feel like how a 9V feels like on your tongue." That is the basics on Tesla Coils. Oh and also... Nikola Tesla invented it (DERP no duh). I forgot to mention. They can be over a million volts and various currents, and powered by multiple types of transformers.

I am going to go play with a million volts in my garage now using my tesla coil.

Twist a coil

The act of defecation in humans.

Can I borrow that magazine? I'm going to go twist a coil.

lick the coil 

To have greatness within your grasp only to watch it get away from you at the last moment.

I'd like to lick the coil someday
like Icarus, who had to pay
with melted wax and feathers brown.
He tasted it on his way down.

Pulling a Coil 

When you are fully capable of great things but you cut yourself short every time

I m pulling a coil and waking up at 2 PM everyday, now over half my life is wasted sleeping.

Tesla Coil 

Read above post also. The most epic thing ever made. There are multiple types, such as Spark Gap Tesla Coils (SGTC), Solid State Tesla Coils (SSTC), Dual Resonant Solid State Tesla Coils(DRSSTC), Vacuum Tube Tesla Coils (VTTC), and High Frequency Solid State Tesla Coils (HFSSTC) , and much more. All Tesla Coils are transformers. They look like weird, thin, and shiny towers. Their size can vary, from the 3 inch tall desktop models, to the 7 feet tall garage models, to the 200 ft tall Lightning Lab models. I need to explain over couple of posts because there isn't enough space to contain all the awesomeness I am about to explain.

I love Tesla Coils. The longer, taller, and wider they are, the better. The more powerful the Tesla Coil, the better. I love that white stuff coming from that top. The more of it, the better.

I need a constant stream of water on my secondary coil when shining it. I need to put one coat of polyurethane on it, sand it down in the water, poly it again, and sand it down, about 10 times for a nice shine. It gets pretty cold outside so I just take it into the shower with me.

flyback coil 

A high-voltage transformer used primarily in switching power supplies and controllers for CRTs. It is named after the surprising effect that it has on the human body when you accidentally gets too close to one.

My old TV's flyback coil finally died.
