Putting together the Clockstar is more than just assembly; it's a hands-on lesson in wearable electronics. You'll be working with the actual components – a gyroscope for motion, an accelerometer for steps, the screen, and the Bluetooth connection – that make a smartwatch function. It's a challenge, but a rewarding one. Coding is optional.
We recommend Clockstar for ages 11 and up. It involves assembling some pretty small parts and following detailed instructions, so it's best for kids who have a bit of experience with building things. Younger kids can definitely give it a try, but they'll likely need a grown-up's help.
No. Clockstar is designed for beginners. You don't need any previous experience with electronics or building kits. The instructions are clear and easy to follow.
Building Clockstar typically takes around an hour. It's a relatively quick and straightforward assembly process, perfect for an afternoon project.
Clockstar functions as a basic smartwatch, displaying the time, date, and including an alarm and stopwatch. Beyond that, it connects to your phone via Bluetooth, and you can customize the display with your own coded watch faces, animations, and even simple games using the built-in gyroscope.
Clockstar is designed to be programmable. Using CircuitBlocks, a visual coding interface, you can create your own custom functions, games, and displays. It's a great way to take your Clockstar beyond the pre-built features.
