I
built this Varmint Caller for hunting. This is an ammo
box modified to house the amplifier parts. It contains
the speaker, a battery, and the amplifier circuit. The
circuit ties to an extra iPhone that I have. I plug an
1/8" phone jack from the circuit, into the iPhone headphone
jack. I set the ammo box out in a field and then an
extra wifi router that I own, about half way between me and
the ammo box. The router is hooked up with a small 12v
alarm type battery. I use a program on my personal
iPhone and also the extra iPhone in the ammo box called
Tango. I have many varmint call type sounds on my
personal iPhone in my music. The program allows me to
send whatever sound I want, to the other phone. I can
also control the volume from my phone. I put both of
the phones on the same wifi group for the connection.
The box also doubles as a 12v supply through banana jacks
mounted on the side of the box for other devices when
needed. |
