Homemade sounder

Описание к видео Homemade sounder

Made the sounder with a lot of reusing metal stuff and magnet wire for the coils. First make one coil until reaching 1 ohm so count the numbers of turn then multiply until 10 ohms, the total resistence for the two coils has 19 ohms aprox.

But the sound was too low if compare with my original KOB, i think because the kind of iron, the homemade sounder use wrought iron, The KOB i think is brass and the sound is more louder with minimal impact.
