Cool Wifi Clock type3

This is a wifi clock .The clock use ds3231 as clock chip, precision is about 2ppm,that means it’s maximum error is about 1 minute per year.It can connect your home wifi through the esp8266 wifi chip .With some simple settings, you can control this clock over the network.It have a funny alarm, you can choose the alarm mode, whether it will keep ringing until you turn it off or only for a minute

Follow our step, you can make a cool network clock yourself

Now let’s start making this alarm clock

Welding Principles
Components are soldered from low to high


first solder the resistor and capacitor, this is 0805 SMD

Look at the picture, Solder the components to the corresponding positions on the picture

10K*3 and 1K*1

the back of the pcb

10K*1 and 1K*2

Next Solder the capacitor

PCB back

Welding power chip,LM1117

this chip can change 5v to 3.3v for the chip working

Welding power indicator led

LEDs have positive and negative poles
The green dot is the negative pole, the negative pad is soldered to the right side

Clock chip,ds3231

You need to learn to solder the smd , it’s not very difficult

This is the alarm clock chip, which stores audio files

triode
This is used as led driver

This is the clock chip battery holder
For power failure time memory

This is the wifi chip which is used for network communication and for controlling the entire clock

At this step, the main pcb has been soldered, finished, now start making the bottom

First use screws to install these two bases
These two are used as base for speakers and leds

Bend with pliers into right corners

Bronze rod, cut into 5cm

Welded one to the speaker

cover a hot tube,This is used as decoration

Another wire

The pins of LED are divided into positive and negative electrodes
You need to use a multimeter to test, which is the positive electrode, which is the negative electrode
If there is no multimeter, welded it freely. If it is not bright in the end, you can exchange the wires of the pin.

Copper rod as negative poles

Welding to the base

For looks beauty, the wire is wrapped on the copper stick

In the position shown in picture, weld two wires

the wire led “-“,to the led base like picture

Led “+”,weld wire

speaker wire

The speaker does not divide positive and negative poles, so the two wires can be exchanged and welded freely

The other wire from the speaker

This is the memory battery holder in the back

it is cr1220

We didn’t send batteries, because it can’t ship batteries , you can buy them yourself at the department store

This does not have to be installed, just a function of the power outage preservation time

Four copper columns are mounted on the base

Fix PCB with screws

This is OLED display

You only need four wires to make it work

We use four copper rods as the wires

Each is 3.5cm

Carefully bend into a 45 degree slope

Adjust the Angle of the copper rod ……………..

bend it here too

After a slight adjustment of the Angle, we finished the clock

Next step we will tell you how to set up and use this clock

Set Clock

WIFI :AutoconnectAP

Password:password

after you connect to the AutoconnectAP,you choose your home wifi ,the clock will remember it,and it can connect your home wifi

USE The Clock
