I have finally finished my ongoing project DecoTime!
DecoTime is my Art Deco styled timer. It is powered by an Arduino driving two x27 168 or switec X25 stepper motors moving the needles. It also uses a MCP23S17 to drive the LEDs and take input from the two rotary encoders. A solenoid rings the bell when finished and the top LED flashes. It can be run off batteries(alkaline or NiMh), or usb. It also has an expansion port to use I2C with power.
You can read all about it in great detail, including schematics and directions.
