Assemble Process

Before you start assembling your kit, make sure to check out our soldering guide: How-to-Soldering-Correctly-Soldering-101. This will help you develop the skills you need to successfully solder the components onto the PCB (Printed Circuit Board). With your new soldering skills, you should have no issue building your own portable Tesla coil.

Step 1: Before, solder the transistor. First, make sure to match the orientation of the transistor to the drawing on the PCB.

Step 2: Solder the resistor onto the PCB, and we do not have to worry about polarity for this component.

Step 3: When soldering the LED onto the PCB, make sure to insert the longer leg (anode) into the positive hole marked ‘+’

Step 4: When soldering the capacitor onto the PCB, you don’t have to worry about the polarity for this step

Step 5: Solder the battery tray onto the PCB, making sure the red wire goes into the positive hole and the black wire goes to the negative hole.

Step 6: Prepare the Tesla coil before soldering the coil to the PCB by removing the protective coat on the wire.


Step 7: First, make sure the wire on the coil goes through the PCB. Before, soldering the Tesla coil onto the PCB after preparing the wire accordingly.

Step 8: Glue the Tesla coil onto the PCB after the soldering process.

The Tesla Coil Principle: How did the light bulb turn on?

In essence, the Tesla coil’s electromagnetic field “excites” the light bulb’s coil, transferring energy wirelessly between the two devices. Furthermore, this phenomenon results from the principles of electromagnetic induction and resonance, which enable the efficient transfer of energy over short distances without physical connections.


Congratulations on completing the CSISLD012 Battery Powered Tesla Coil DIY project! You have successfully built a portable and electrifying device that showcases the principles of electromagnetic induction.

Finally, with your new Tesla coil, you can now mesmerize friends and family with its stunning visual effects and experiment with the fascinating world of electrical engineering.
