Welcome!

With tinyTesla you’ll learn about electronics, flex your soldering 

muscles, shoot lightning, and play music using electricity! 

A Tesla coil is a device that uses resonant circuits and alternating 

current to produce extremely high voltages. Originally invented by 

Nikola Tesla in the late 1800s, Tesla coils have progressed from 

spark-gap circuits to designs involving modern solid-state  

switching devices such as MOSFETs and IGBTs. While there are 

many types of Tesla coils, what they all have in common are  

air-cored induction coils. Using a Tesla coil is the best way to 

produce a continuous high-voltage streamer.

We’ve designed a Tesla coil kit that’s both easy to build and 

beautiful. tinyTesla is an SSTC, or “solid state Tesla coil,” which 

balances performance, musical ability, and reliability. 

But be careful! Building hardware can be tricky if you’re  

inexperienced or don’t have the proper equipment. Work with 

good tools, pay close attention, and ask for help when you  

need it. 

Most of all, have fun!

Note: 

We try our best to keep all images and  

instructions consistent with the latest revision  

of the tinyTesla hardware, but the photos in  

this manual and on our website are not always 

identical to the components you receive in  

your kit. They will, however, maintain the  

same functionality.
