Low quality

This could have been a really cool kit but that tiny flyback transformer has issues.In the first set, the negative wire was detached and there's no practical way to reattach it. It seems like they crush the edges of the coil housing to secure it rather than a dab of glue or whatever.The second one looked okay but I foolishly tried to solder the wires to the circuit board. Don't do this. First, sand the ends of the wires with actual sandpaper to get off the lacquer insulation. Break off three of the pins from the pin header that was included and solder that into the holes. Then wrap your coil wires around those pins and solder to the pin if you can.I still couldn't get this to work but maybe I can reuse the ferrites...

Poorly designed

The circuit is poorly designed and exceeds the transistor ratings causing it to fail. Apparently the board was layed out for a different transistor as the D882 has the base and emitter reversed and has to be mounted with the heatsink on the wrong side rendering it almost useless. There are no instructions or even a schematic. The transformer has two unmarked windings, a heavier primary and a finer feedback, so you have to figure out polarity yourself. I used the transformer in another project with a completely different drive circuit and it worked well for a spark ignition system, so I got some use from it.

It works... After some troubleshooting.

This has all the parts you need to create a spark - from an earlier post, the transistor is indeed backwards. I mounted mine on the opposite side of the board so the heat sink could still be soldered down, but then you can't set it flat. The other thing to keep in mind is the transistor windings have to be in the proper order. I used a multimeter to figure out which leads were connected. If it doesn't work, you will have to swap one of the coils to the opposite polarity. Overall, this got me what I wanted, but I can understand frustrations because it does require some troubleshooting to get it to work properly.

THIS IS JUNK DO NOT BUY.

Before soldering the components to the circuit board I tested each using a VOHM meter, I tested the transistor with my semiconductor tested all parts individually seem to be fine but after assembling and soldering, the project does not work. I then tested and assembled the second project using a breadboard, it did NOT work either. I have tried switching the transformer windings in as many configurations as I could imagine, all failed. This project is JUNK.

A waste of money; transformers are improperly wound

Purchased two of these in a package from Amazon, and went over each of the included parts with my multimeter, including the circuit board. Everything was fine except for both transformers, which were incorrectly wound (broken wires in the center). Two broken out of two doesn't speak well for the overall quality of the kit. It is definitely worth looking for an alternative unit that is assembled and tested.

It does not work.

The transistors that came with the kit are NEC D882. The pins on the D882 are emitter, collector, base. The schematic shows that the pins should be base, collector, emitter. I also think the high voltage side of the transformer is not working. It seems that the other reviewers were correct when saying this kit is defective. It was only $7, so I won't take the time to send it back.
