Obrigado Banggood

Reached late, but in very good condition. Thanks.

Dear Sir/Mam, i received package having following contents in it pcb transformer battery case one screw heat sink diode but npn transistor resistance is not in the package sending images again Hope i am sending complete details to resolve the issue regards nishant

The kit only needs some solder work to run. The transformer connections are a bit tricky. I bought two kits and the leads for "thin" primary were wound differently for both. I simply swapped the connections and it worked. A word of advice: if it does not work the first time, immediately switch the circuit off to avoid damage to the transistor which can become extremely hot.

very nice product

Took very long to get it but I was no hurry. Soldered the kit together and it worked on the first try. Spark gap is about 1mm with one AA-battery. Only downside is that the battery holder does not fit to an AA-battery. Nevertheless I am satisfied.

è arrivato in tempi giusti, il materiale è ben fatto, consigliato.

really neat project and seems like a simple build, but I have tried 3 of them and I have yet to get one to work. but the videos I've seen they work great.
