What is it?
The Weasley clock is a magical clock which, instead of pointing to the time, points to the location of the indicated person. I created one using mini-steppers, an iphone Find-my-iphone app, an Arduino, a network shield, and an old clock purchased on eBay.
What was the process?
The first problem arose when I couldn't find five concentric copper tubes large enough to nest inside each other, yet small enough to remain tight. I had to solve that with a bunch of sanding and paper. The back of this clock is a mess. I tried the Inkjet transfer PCB creation method, and it didn't work. I ended up with a sawed in half breadboard and about a hundred jumpers going everywhere. On the software end, I learned that Arduinos didn't like networks or strings, so I had to deal with that. The only easy part of this project was the bell that signalled the changing of the hands.
What did I learn?
The end result for this project wasn't perfect. One of the hands never worked due to faulty gear alignment, and the rest tended to stick to each other. I plan on remaking this more successfully in the future. Despite its flaws, it worked for a couple days before being torn apart and packed up for the move to Singapore.
