This is a really fun little kit. Imagine a working Little Tesla coil for this price. I assembled it in less than 20 minutes and it worked great. I placed a CFL bulb next to it and it lit up like it was plugged in. Obtain some silicon adhesive to glue the secondary onto the board.
Thumbs up! Easily assembled, but two points of caution: The rounded and squared markings for the LED on the board are a little misleading, so DO follow the +/- signs. Secondly, the wire is exceptionally thin, so be careful scraping the enamel. A real joy to play with.
A cool little device, easy to build. Good instructions with slight errors that won't affect the final outcome. Suggestion: trim the kapton tape covering the secondary coil if needed so its base is flush to the circuit board and use silicone seal to attach it. Also refer to the picture when it's time to install the primary coil (red loop) as this picture is not included in the instructions. Using a heat gun to soften the insulation on the primary loop will allow you to form it into a shape that stays put.
And just fyi - it ran at 3.7 MHz
A person with only a modest level of experience can assemble this and have it running in minutes. As others have already said, make sure you only go by the - /+ symbols on the board when you install the LED and ignore the flat side marker because it's incorrect. I used a small amount of thermal transfer compound when fastening the transistor to the heat sink. You will need some kind of adhesive, silicone, or hot glue etc... to fasten the secondary coil to the board. Very fun and also enjoyable to see other people's excitement as well. This would easily be very inspiring to a younger person or someone beginning to take an interest in science.
