Component list:

Installation steps:
1>. Install MIAN RES: R31=1 M ohms; Other resistors are 3.3K ohms

2>. Install CAP: C2=222P

3>. Install E- CAP: C1=22uF, Notice that the positive electrode of electrolytic capacitor can not be reversed.

4>. Install Directional switch. Bend the switch 90 degrees, and then install it to SW1.


5>. Install ADJ-RES:
VR1=104K. Note that the adjustable resistance should be soldered to the back of the circuit board.


6>. Install power switch:
Pay attention to the installation direction installation direction of the switch.

7>. Install IC:
Pay attention to the installation direction of the IC. U1=CD4069. U2=U3=CD4015.

8>. Install 8pin Connector:
Refer to the picture below, install connector to CN5, CN6, CN7,CN8.

9>. Install LED panel:
Install 30 LED on the circuit board. The long foot is the positive pole. Install on the rectangle pad.

10>. Install pin connector:
Install the short side of the connector to the back of the circuit board.

11>. Install main and LED:
Install the motherboard and LED gently press together A point to A, B point to B.

12>. Soldering power cable:
Red line is positive power supply DC5V suitable for USB. 3 section AA or AAA battery box.


Warm Tips:
Light- emitting diode and electrolytic capacitor the longer pin is it the anode it should be installed on the rectangle pad of PCB. Refer to the picture below:
