Simple Radio Control Circuit to actuate common electronic device. The circuit specifies a whip or wire antenna which just means a solid piece of wire 6-12 inches lengthy (15-30cm). The antenna coil is experimental, however you are able to begin with ten to 12 turns of #22 (0.7mm) magnet wire, and 5/16″ (8mm) coil diameter.
Antenna wire is soldered at 1/2 turn of the coil and the gate of the BRY35 is soldered about halfway the coil. This circuit will transmit as much as 100-feet with the above specifications @ 30uA.
