    It only took me about 30 minutes to put together. Make sure you pay attention to the polarity of the capacitors and LEDs when you install them. Also, there are 2 different types of MOSFETs in the kit and the PCB will be labeled with where each one goes. The pictures in the BangGood listing are pretty misleading as there is no electricity shooting out of it once it’s built as shown in the picture. I tried it from 3 volts all the way to 24 volts and, while things do change at different voltages, there’s still no electrical light show like they make you believe. I also wanted to get this to help me practice soldering and, since this only has a few pieces in it, it is a pretty good kit to start with. I made a full video about it here: https://www.youtube.com/watch?v=_eMg0dcVrHg

    Works as stated. The blue spark is very tiny but the luminescent bulb lights up spectacularly. You can present it like a nice trick to the kids. I have added a thermo-silicone paste between the transistors and their heat sinks. And finally I put a small fan from an old video-card - no worry to burn out the transistors even at 25 V.
