Rules for ** Add your Tesla coil here **

The rules for posting on this thread are on page one and are a bit different to other threads in 4HV. This is to allow a fairly consistent and brief approach to allow people to compare a large number of different coils.

A reminder:
The 3 Rules to keep it consistent and readable:
Each coil to have only 1 page of info (ie fits on your computer screen). Brief is best.
Each coil to have only 2-3 photos (do not double post).
Only coil details and photos to be posted. Direct any queries direct to the person or in a new thread.

A coil is defined by its secondary (change of toroid isn't a new coil)
Enter as many coils as you wish. Beginners coils are welcome and this log is designed to be helpful for beginners.

Enjoy!

My briefcase coil. Secondary stores flat so nice and compact when closed. Sparks taste good too!

First SSTC I ever built, second tesla coil I ever built.
This coil runs very reliably and can be run indefinitely without parts overheating.
Coil also has been audio modulated.

Coil stands about 3 feet tall
full bridge of IRFP260 MOSFETS
max spark length of about 15 inches
120v full/half rec mains
secondary 18 x 4.5" 1800 turns
primary 5 x 5" 6 turns

Hello Forumers

1st POST in this section...

here is my FIRST ever tesla coil.. dated AUGUST 2009


this is where it all started.. my ZVS driven Spark Gap Tesla Coil (SGTC).. not much of a performer though (lack of know-how) and pri LC tank cap keeps getting DEAD.. maximum spark length is 6"-7"...


here shown is the ZVS flyback driver.. using IRPF260... powered from 80VDC @ 8A (or so I remember)

Zvs


the whole setup

Setup


and a short video of it.. topload is crumpled aluminum foil... closer to primary LC resonance...

for more info, here is the link:

thanks!
