PlotClock Upgrade
thingiverse
To ensure compatibility with Expo erase markers, modify the holder from http://www.amazon.com/Expo-Erase-Markers-Black-86001/dp/B0006HXJFK/ref=sr_1_8?ie=UTF8&qid=1401373557&sr=8-8&keywords=expo+markers+dry+erase. Add a funnel to the eraser for easier marker replacement and deepen its channel for a snug fit. The accompanying C# program runs on the FEZ Panda II board, utilizing the DS1307 RTC driver from http://netduinohelpers.codeplex.com/SourceControl/changeset/view/dfb899d1e153#Hardware/DS1307.cs. For reference, use Joo's PlotClock (thingiverse.com/thing:248009) as a guide for additional parts. When attaching the bigger holder (biggerholder2.stl), ensure the extension part of the hand is entirely above or below the other arm piece to avoid interference with movement. Alternatively, use biggerholder.stl without the extension.
