Retro Desktop Temperature Sensor, Clock, Weather Station, Arduino based, 0.96 OLED Display

thingiverse

You want to print: one base plate, one top, one battery holder and three buttons. Battery holder is this: http://www.thingiverse.com/thing:941081 You may have to print different length holders if you use a different kind of battery. The main hardware parts are: an OLED display, a lithium battery, a charger module, a clock module and a beeper. Full HW component list: https://github.com/goldiee36/desk-clock/blob/master/README.adoc I used a hot glue gun to fix the components into the case and CAT5 Ethernet wires that connect the pins. To save space, I removed all metal pins from the boards like the OLED display or the clock module. Edit: software is updated to v0.35: new feature - auto on-off: currently active; the screen turns on at every workday at 8:30 and turns off at 18:00. Edit: software is updated to v0.3: capable of showing temperature, humidity, time and battery voltage. As this is a battery-powered project, I really care about power consumption. Basically, the only thing that consumes power is the OLED (if it's powered on). The Arduino and the clock module are in sleep mode for most of the time. If the screen is switched off, the power consumption is ~11uA even though the software keeps all functionality running like temperature logging or alarms. https://github.com/goldiee36/desk-clock Print Settings Printer Brand: Printer: Supports: Notes: I used 0.26 mm layer height, no support, ABS with brim. 100% infill. The walls of the case are only 2mm thick. Some bridging capability is needed for the button holders.
