CLOCK
Be very careful with static
electricity. If clock not work after
build its mean that they been
damaged by static
electricity in process of
assemble.
Check resistance between
+3.3 and GND pins of XS2.
The resistance should be not lower
1kOhm.

1) You have a PCB with ICs:
2) Place all resistors vertical.

3) Place photoresistor. I recommend to make h = ~20mm.
4) Place all capacitors. Be careful with polarity!

C 12,C13 and Q1 should be empty!

5) Place all transistors, 3.3v stabilizer and temperature sensor:

6)Place diodes and be careful with polarity:

7)Place 3 buttons:

8) Place battery holder and insert battery when clock will be fully
assembled:
9) Place buzzer and be careful with polarity:

10) Prepare and install LEDs. LEDs should be UNDER PCB:

11) Place infrared receiver for remote control:

12)Place 8pin socket:
13)Prepare and place TA chip. You can use some heatsink
between radiator and TA chip:

Use double-sided adhesive tape for fix radiator to PCB.
Then solder TA chip to pins on PCB:

14) Completely assembled board should look like this.

15) Prepare the IVLM tubes. The numeration start from most
long wire and go in clockwise.

16) Prepare IV-6 tubes, similarly. The first pin – the longest
pin.

17) Insert tube into holes in PCB:
18) Put clock on the flat surface and solder the tubes.

19) Then check the resistance between GND and +3.3V pins of
XS2 again. It is should be not lower 1 kOhm.
20) Then plug 12V DC adapter. The microcontroller starts
work and you will hear short melody. LEDs start work too and
should change colors. If it not happens, check the +3.3V and
resistance on XS2 between GND and +3.3 pins.

21) After all clock should work.
