DIY KIT Electronic Clock with Aliexpress

Good day to all. Today, the hero of this article will tell and show how to collect these electronic clock do it yourself, from the set that can be bought on Ali at the link below.

Consists of a set of housing and electronic parts.

Body.

Control controller.

Pay.

Clock face.

Power cord.

Small fluffiness.

Bolts and nuts for connecting parts of the housing.

Tinted film and assembly instructions.

In a bag with loose powder are: Resistors with a nominal value of 330 Ohms., 10 kOhm., Capacitors 22 and 104., Transistors 8550., power connectors, tweeter, photo and temperature resistors, 32768 crystal oscillator, and buttons.

In order that there would be no further surprises, the author checks the resistors before proceeding with the assembly.

And proceeds to assembly and soldering. First, he put all the resistors on the board according to the circuit. Then he soldered them well and cut off the extra legs.

Then the author proceeded to 8550 transistors (four according to the scheme), put them on the board and first soldered one leg for convenience, and then soldered the remaining legs and cut off the excess.

Next, the author mounts a quartz generator solders and cuts off excess.

Then the capacitors, installs according to their nominal value, solders and cuts off the excess.

Then the battery holder and power connector are mounted and soldered.

Now the author mounts and solders the sockets for the controllers.

According to the keys.

Then the buttons.

Next squeaker, installation and soldering.

Further, the author mounts and solders the photo and temperature resistors.

Now the author will install and solder the dial. The points on the dial should be according to the pattern.

Then install the controllers in the sockets.

This is how the board should look when assembled.

Then it connects power and checks the operation of the collected watch.

Everything works and the author started assembling the case after removing the protective film.

Sequentially fastening the housing plates with bolts.

The final stage, the author will glue the tinted film.

Well, the author has finished assembling the watch. This watch, in addition to time, also shows the date and temperature, and has an alarm function.

Thank you all and see you soon.
