Mini musical Tesla Coil

 

Mini musical Tesla Coil

Intro:

this is another project about the tesla coil,But!we add a music play function .

How it work?

Use the IRF3205 FET to Amplified music signal,Modulation to the current of the Primary coil,so when the spark come out,the music played

OK,let’s start making

First check what you got in the packet,The following image contains the main parts , see if  there  is something missing………….

 

 

Step1

first you need bend the foot to Bent right angle,why do this?see the second pircter you will know

 

 

 

Step2

Welding IRF3205,you need make suer that  the bottomo side of  IRF3205 keep very closed to the PCB

Step3

Welding TIP41c

the tip41c is the main part of the tesla coil,it using The principle of feedback self excitation,drive the tesla coil work

 

 

Step4

Diode.need pay attention that the diode Polarity,there is a Line on its body,welding as picture

diode is used for Isolation high voltage of primary coil ,Protection input

 

 

Step5

104 Capacitance

first Cap you need let it Lie down,this is for making space for the Heat sink

 

 

the secoun cap is used for the audio input

 

Step6

20k Adjustable resistance and Audio jack

the resistance is used for Set the potential of the IRF3205 G foot

 

Step7

Led long foot is positive,welding to the mark “+” on the PCB

 

 

 

Step8

10K and 1k resistance

if you do not know which is 10k,plz use a multimeter or google “Five color ring resistance identification”

 

 

1k

this is for the Power indicator LED

 

 

 

 

Step9

Swich and Power jack

 

 

Step10

Heat sink

The heat sink with double-sided adhesive on the chip

 

 

 

Step11

The coil.

first you need Distinguish the Top and bottom,Wider tape is the bottom

Then take of the first layer tape,put it aside and use it later

 

Step12

ok,this step maybe the Most difficult,you need  Winding Primary coil

Parameter requirement:

3 rotations
Clockwise
compact

First use one finger hold the wire

then 3 turns,clockwise!

adjustment
Make sure the coil is tight,this is very important,Direct impact spark size,if too loose,Will reduce efficiency

Remember which side is IN.which is OUT

Use the tape that you put aside before

Fixing primary coil with adhesive tape

REMEMBER the IN and OUT side!!!!!!!!!!!!!!!!!!!!!

Step13

before we welding the Secondary coil to PCB,first we need fix the pcb on the wood

 

First need to locate in the four hole poke a few pits

 

 

diagonal
Screw

 

Do not tighten all screws at once

Screw the screws when all the screws are set

 

 

Step14

The smallest wire,welding to L2 on the PCB

 

Then the IN and OUT side,I hope you remember them
If you turn the 2 counter, it won’t work, but don’t worry,
Just exchange it

 

 

Glue the coil on the wood

Step15

Screw the fan

 

Step16

This need 24v power,so plz find a dc power 24v,current better greater than 1A

 

 

OK,when you finish this,you can click the switch,if all goes right,the spark should come out,then connect the audio wire to your MP3 player or phone,you can enjoy Music………
