This circuit is a low power Wireless Power Transmitter With printed Coil on the PCB using IC 555.
Parts list:
IC 555
Transistor BD139
LED 12(pcs)
Resistor 120 ohm
Resistor 5 ohm
Resistor 18K
Resistor 20K
Capacitor 40pF
Capacitor 680uF
Capacitor 2000uF
Capacitor 100nF(2pcs)
Heatsink for BD 139 transistor
3V Battery
Circuit:
The first circuit used to running some LEDs in the receiver side and the second circuit used to running a small DC motor.
The transistor slightly gets hot, so its better to using a heatsink for it.
