About this 3D model

Update #5: Description of the calibration process -> Instructions Update #4: Minor bug fix in the Calibration routine -> v1_1b Update #3: Improved servo arm attachment. See Instructions Update #2: Additional version of the servo arms. See Instructions Update #1: Videos of the plot thermometer/clock: http://youtu.be/0nTKUaYZzgA and http://youtu.be/XSc-_maon80 (please see further update info under instructions) This plot thermometer and plot clock is based on http://www.thingiverse.com/thing:248009 and http://www.thingiverse.com/thing:255608 Initially only with the intention to replace the screws with printed hinges I made several improvements: Hardware: - Printed hinges - Fully cover of the electronics - Covered servos - Thermal measurement - Integrated switch and power jack - Hooks for wall mounting - I2C connector for further enhancements like motion sensor etc. - mechanical stability - FDTI programming port for the arduino - Magnetic drawing board holder Software: - Inline calibration & setup (use x when connected to a 9600 serial terminal) - EEPROM storage of the calibration values - temperature measurement capability based on a DS18B20 - possibility to choose between time and temperature display - Display flip capability (for wall mount) - switch for multiple functions (temperature or time / plot on or off)
