mini ball-gap spark tesla coil SGTC

 

 

In the DIY process, if you have any questions that you don’t understand, please send an email to our email address(bluefox911@163.com), the title says SGTC, we will reply you in the first time after seeing it.

This is a mini spark gap tesla coil(SGTC),it is small but full funtion.The most important thing is that it can touch and don’t worry about the electric shock injury.The original intention that we design this decive,plz reference The following article

make a Mini table SGTC tesla coil Spark gap Tesla coil


 

First  briefly introduce this Tesla coil project:this is the third mini SGTC Project,It is basically the same as the previous three Project, except  the part of the spark gap, we use the ball gap

The ball gap can be adjusted, the basic range is between 0.1-1mm, different gaps will lead to different discharge frequencies and charging voltage of the capacitor, so the discharge effect is different, you will feel the fun of trying………..

OK,let us start making it

 

Step1

Scattered parts

Foam is buffered at the bottom

step2

The transformer coil needs to be installed according to the picture, and the rough copper wire is the primary position.

Please look at the annotation on the picture

step3

High voltage diode

step4

Power indicator lamp,led long foot is +

step5

Power socket and switch

 

step8

this board is used to  turn 12v DC into high frequency AC

on the back there is label “+”,”-” and “”out“”

 

 

red wire is +,yellow wire is –

soldering to the right place marked in picture below

follow the picture,do as picture………

ok,the board finished

 

step9

now need connect the Primary coil and secondary coil to this board

first glue the bottom shell

In order to look good, we use UV curing glue, transparent

The perfectionist can be like us, but if you do not mind
Then just like you,Any glue is all right.

(Acrylic board back)3 silicone pads stuck in the corner
Another need to reserve space for the nut, so don’t stick to the corner

Assemble the board

The primary coil winds three turns(Although the bottom is reserved for 4 turns, but please winds only 3 turns,and must Clockwise)

 

 

 

Now solder the “IN” “Out” “L2”

The soldering place  is best to do insulation treatment,
Prevent discharge(Cover exposed wires with tape)

The wire of the secondary coil is soldered to “L2″

In fact,” L2″ and ” Out” is connected…………

install the Nylon nut ………..

Copper column,make sure the hole on the Copper column is like picture

the Copper ball has hole,you need solder the Copper stick on the hole….

Adjust the distance of the copper ball, the interval should be less than 1mm, otherwise the voltage can not work through the air, it can not work, can be adjusted in the range of 0.1-1mm, can get different discharge effects

Determine the distance and lock with the nut………..

 

 

Ok,finished all the assemble,and about the metal top load,just put it on the Secondary coil………No need to fix

About the power suply:

you can use any DC12v power suply(make sure the out put current is 1A-2A)

For example:

 

 

if you don’t want to use the plug,you can solder two wire directly to the board,and connect them to your DC12v power

 

 

ok,all is done,12v dc power,you can use it now(plz use it in dark place,you can see the spark and arc)

find a Incandescent lamp

    I cant stop the arc from the in line to the coil. I have tried every thing
