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………….
first you need bend the foot to Bent right angle,why do this?see the second pircter you will know
Welding IRF3205,you need make suer that the bottomo side of IRF3205 keep very closed to the PCB
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
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
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
20k Adjustable resistance and Audio jack
the resistance is used for Set the potential of the IRF3205 G foot
Led long foot is positive,welding to the mark “+” on the PCB
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
Swich and Power jack
Heat sink
The heat sink with double-sided adhesive on the chip
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
ok,this step maybe the Most difficult,you need Winding Primary coil
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!!!!!!!!!!!!!!!!!!!!!
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
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
Screw the fan
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………
