In an electronic board I've found an LCD Counter and Hour Meter. Here's the technical information.

Since it's very expensive, I would like to save some money making it with a custom project (maybe made with a cheap LCD and an Arduino or dedicated micro).

Can I achieve the same results?

Is it so expensive (almost 25$) because it has some advantages or particular characteristics?

    \$\begingroup\$ The price of a product isn't always related to its properties but also to supply and demand. And $25 isn't that expensive for an industrial module like that. Yes of course you can make your own. Do realize that if you do not know how to do that it will cost you a lot of time to figure that out. So how expensive is your time? \$\endgroup\$ – Bimpelrekkie Feb 14 at 8:19

    \$\begingroup\$ Did you notice that it runs from 12 and 24 V DC supplies (common in industrial applications) and, I presume, keeps the hour count during power interruption. By the time you've done all that you'll find that your home-made solution will be the same price and five times the size. \$\endgroup\$ – Transistor Feb 14 at 9:52
