Tesla Coil Kit with Audio Input

Amaze your friends with this cool musical tesla coil kit. When fully assembled, this module will act as a tesla coil which will play audio through the arcs when an audio source (e.g. phone, laptop) is connected to the audio input of the coil. It runs on 15-24V DC, either from batteries or a power supply (not included). 

 

Power Input: 12-24V DC, 2.1 x 5.5mm 
Audio Input: 3.5mm stereo socket (only the left channel is active)
PCB Dimensions: 80 x 38mm

Please note: Tesla coils produce very high voltages; do not touch this device when it is turned on! This device produces intense radio frequency interference which can affect any electronic devices near it (e.g. pacemakers). Lastly, the arcs produced by Tesla coils can ignite flammable objects; keep all flammable objects away from the Tesla coil.
