How to assemble a DIY electronic hourglass kit step by step

Hello and welcome back. In this project, we will learn how to assemble a DIY electronic hourglass kit step by step provided by OSEPP. It has a good quality and cheap price. Also, we can use this kit to improve our soldering and electronic skills.

What is an hourglass?

An hourglass is a time measuring machine used in the past. This is made using two glass bulbs and it contains very fine sand. Also at the point where these two bulbs are connected together, we can see a small hole where the sand travels. We can see these in different shapes, and the measured time also varies according to the size of the glass bulb and the size of the hole. You can use this link for more information about these hourglasses.

Also, this hourglass kit is designed using the above structure and it includes 6-time circles. That is 30sec, 1min, 2min, 5min, 10min and 15min. You can choose the time you want from this. Also, it has two buttons. That is the “Select” and “Start” buttons. You can use the “Select” button to change the time circle and we can start counting the time using the “Start” button. We can observe all things through LED and buzzer.

OK, let’s assemble this kit step by step.

Step 1

Firstly, unbox this kit and identify those components.

Step 2

Secondly, let’s solder these components to the PCB. For that, use the following tools.

Step 3

Now, start the soldering mission. First, solder the LEDs one by one.

Step 4

Then, solder the mini push buttons and female headers to it.

Step 5

OK, one PCB is perfectly done. Now let’s solder the other components. Use a second PCB for that. First, solder the IC to the PCB.

Step 6

Next, solder the 1K resistors and 100nF capacitor to the PCB.

Step 7

Then, solder the switch and the 330-ohm resistors one by one.

Step 8

Next, solder the tilt sensor and buzzer to the PCB.

Step 9

Finally, solder the pin headers and battery clips to it.

Step 10

Well, everything is done. Now connect the PCBs together as shown below.

Step 11

Finally, put the batteries to your hourglass and power on it using the switch. After, select your time using the Select button, and then press the Start button.

Ok, enjoy this hourglass kit project. The full video guide is below. So see you in the next project.
