Once you have all the appropriate components, tools, and equipment, the entire build process takes about 20 to 40 minutes tops. It's a relatively inexpensive DIY project, with a total cost of about $250– $300 (not including labor).
A battery charging circuit, a vibrating motor for updates and silent warnings, a completely programmable Arduino-compatible core with power regulation and Bluetooth LE support, and finally, an OLED display with physical buttons are all needed to be designed from scratch.
The official site has all of the circuit diagrams and installation instructions, so you should be able to put it together with a bit of practice. He also has a comprehensive list of the tools, hardware, and components required to build your smartwatch. There are direct ties to a supplier for these components, so don't worry about finding them. You can always look for them on your own if you want to or substitute parts as required.
To make the watch face, back, logic frame holder, hardware padding, communication port, and strap brace, you'll need a 3D printer.
Homekartz has successfully designed and tested several different displays for his smartwatch builds, and he goes into great detail about his experience. You can choose between an OLED monochrome display, a Sharp monochrome display, or an OLED color display. When you make your smartwatch, what they have to offer — including price — will vary depending on what you want.
From beginning to end, you can follow homekartz's instructions to assemble the device. You can have something working in no time if you have a little patience. As for the finished product, it can display a wide variety of notifications from smartwatch messages, alerts, and more.
It also displays the time — as you'd expect — and can be programmed to show alerts as needed. You can do pretty much anything with the computer because the program is open-source, as long as you know how to code.
If you don't know how to code, your options for what you can do with the finished project will be restricted, but you should still be able to put it together. Homekartz has made all of the required resources, including the software, publicly accessible, on a dedicated website.
