How to make tesla coil

When it comes to selecting topics for science fair project ideas its a big pain but good topic like How to make tesla coil might solve your problem!

Note: If you want video tutorial i have provide that too at bottom of this page make sure to have a look at the end

Why To Make Tesla coil

  • Fun and interesting project which can be built as hobby project or class project
  • New question arises which may lead to origin of new ideas
  • Enhances lots of learning related to electronic and its properties
  • This tutorial is about How to make mini coil for science project that contains all the circuit diagram and necessary explanation to build one
  • Easy steps with pictures makes it easier for beginner to understand

Supplies Required

Tesla coil project materials
Tesla coil project materials
  • PVC Tube of 15cm will be main part of this project well if you don’t have plastic tube, Cardboard tube also works fine
  • 2N 2222A transistor that is responsible for amplification in this project
  • Insulated copper wire to make coil windings
  • Some pieces of gum tape
  • Base of cardboard or plastic to settle all components
  • Few wires and 9v battery

Circuit Diagram for Tesla coil

After gathering all the materials follow up this circuit diagram if you have trouble understanding this i have made it more simpler by giving explanation below

tesla coil circuit diagram
Tesla coil circuit diagram
  • Coils one and two represent end of windings from tube (winded to PVC tube)
  • For your convenience i have given names as A and B to ends of small tube
  • 2N 2222A transistor has Emitter, Base and Collector like any other transistor
  • 22k resistor for positive terminal connection in battery
  • Negative of battery to emitter part of transistor
  • Connect A of coil to collector
  • Solder 2 and B of coil end to collector

Building frame

Finishing tesla coil
Finishing tesla coil
  • Start by closely winding copper wire across tube
  • This may take while to finish
  • After winding insulated coil with enameled copper wire remove coating from ends
  • Either heat with matches or scratch with ruler to get rid off enamel
  • Make coil of smaller size as shown in visual above
  • Place both coils on piece of board make sure long tube is outside smaller tube
  • After this follow circuit diagram and make connections
  • Solder required points and cover with hot glue or insulated tape if necessary
  • For charges displacement i use aluminum foil ball
  • Fold normal aluminum kitchen foil into shape of ball
  • Place it on top of pvc tube (long part)
  • Here end 1 i.e. top end of pvc tube should be connected to this foil ball
  • Connect power source , here battery rated 9v was used
  • For safety i use resistor
  • Adding switch is recommend if this project is taking bto school for exhibition purpose well its an option
  • Connect battery and check project by getting cfl or tube light closer to this
  • If bulb starts to glow which indicates your project fine if all the steps were performed same it will definitely wok
