The most stylish and practical hat you're ever likely to see

26th January 2023

Support this exciting new project! The video shows the base unit in action, but there is a lot more planned. The next phase is well under way, but needs more stepper motors and at least four worm drive gearboxes. Any donations towards the cost would be hugely appreciated.

Anyone kind enough to donate GBP £10 or more can have their name printed somewhere on the robot. The robot will make many public appearances, so you'll get plenty of chances to see it.
