7 Segment LED Clock

Featured on [All3DP](https://all3dp.com/weekend-project-3d-print-a-sleek-7-segment-led-clock/)! This [7 Segment](https://en.wikipedia.org/wiki/Seven-segment_display) LED clock was designed to be almost entirely 3D printed, with the exception of a few fasteners... and of course, the electronic components, which are all neatly encased inside of the clock itself. It relies on the translucent properties of thin layers of white PLA to achieve the light diffusing necessary to light up individual segments. I created this project to get more experience in modelling for 3D printing using Fusion 360, practice my soldering skills, and get a chance to do a little ESP8266/Arduino programming. ***Features*** * hang it from the wall using the built in hole(s) or print 2 optional stand pieces for a desktop configuration * avoids clock drift by syncing with [NTP](https://en.wikipedia.org/wiki/Network_Time_Protocol) periodically * automatic time zone detection (uses IP to approximate your location, which should work for most scenarios; this can be overridden with a more accurate location if this is getting the wrong location) * automatic daylight saving time adjustment - no need to spring forward or fall back manually * [12-hour](https://en.wikipedia.org/wiki/12-hour_clock) or [24-hour](https://en.wikipedia.org/wiki/24-hour_clock) format * custom LED colors - over 16 million colors possible * choose from hour:minute (HH:MM) or hour:minute:second (HH:MM:SS) * over-the-air firmware updates
