Fun small electronics kit build. Took many tries to get the primary coil correct number of turns, turn direction and polarity. Two loose turns clockwise from the bottom up, bottom end connected to the "front" connection point. A 12vdc 1amp power brick works far better than a 9v battery but start with a battery. Finally, nothing seemed to be happening until I touched the top secondary coil wire and it came to life! Audio thru this tiny coil is so hard to believe but it works!

Works well specially with florescent light . Be careful - do not connect the audio without an isolation transformer or RFI filter . I burned my old MP3 player

It's not more than it says. A small Tesla coil, which is perfect for decoration, and sounds interesting!

Assembly took around 15 minutes, very easy. Fun until I've shown it to everyone, now it sits on top of my computer at work as a figure. Nice if you're just barely starting electronics.
