Banggood

Si monta facilmente attenzione al filo risso se avvolto da lato sbagliato non funziona. Se si tocca la scossa si sente ma non è pericolosa. Funziona anche con 12v. Il suono è di bassa qualità, ma è un gioco...

Even though I received a slightly different model of kit it still works just fine. The arc is a lot bigger than I expected it to be but the sound quality is understandably sub-par. Overall a great kit.

awesome product. No instructions were provided, so if you are not familiar with circuits it might be difficult to understand. found great videos online on how to assemble and operate. very good for a small project that I did with kids. they loved it. Caution the fins do get very hot!!

Easy to build. actually sounded better than I expected. Incorporating this into an effects module for a synthesizer and theremin.

impeccable

OK

vey low volume
