USB mini golf set

We came across another crazy USB device on the World Wide Web.

The mini golf set shown in the picture can be fun for a while, we can start a small house tournament against our colleagues and classmates, but it is sure to fall into the category of crazy rather than useful USB devices.

The set, available for £ 9,99, includes a mini golf course, two rackets and six golf balls. We may rightly ask the question, what does the energy received through the USB port still work with? The answer is much simpler than you might think: on a successful hit, the absorbed ball is highlighted and rolled back by a tiny mechanism.
