DecoTime angular timer

thingiverse

<b>DecoTime</b> is my stylish Art Deco timer, powered by an Arduino driving two x27 168 or switec X25 stepper motors that smoothly move the needles. It also uses a MCP23S17 to drive the LEDs and take input from the two rotary encoders with ease. A solenoid rings the bell when finished, and the top LED flashes in synchronization. You can run it off batteries (alkaline or NiMh), or use USB power. An expansion port allows for I2C connection with power. Find the knobs, battery pack, and needles in my other uploads on Thingiverse. You can read all about DecoTime in great detail on my website, including schematics and directions. Check out http://coolate.com/blog/coolate-pages/deco-time-angular-timer/ to learn more. I printed the parts on an Ultimaker, seeMeCNC, and an old Makerbot. The two main parts require supports, and should be printed inside down toward the plate for optimal results. I used PLA, and coated some parts with XTC to make them shine. All design work was done in Tinkercad, and are public if you want to modify or experiment with them.
