7 Segment LED Clock

Introduction

My entry for the PrusaPrinters “Timekeepers” contest (Don't forget to give it a like...)

Some ideas for upcoming versions:

- Software

- DONE - Integrate WiFiManager for easier setup

- DONE - Configure the timezone/time offset in a Web GUI (set automatically during WiFiManager configuration)

- DONE - Show temperature

- DONE - OTA (Over The Air) Updates

- DONE - Set the brightness depending on time of day or a brightness sensor

- Buttons to change the brightness and color

- Hardware

- Back lid to mount it on a wall

- Bring down the thickness to around 30mm for wall mounting (40mm is fine for the desktop version)

- Provide a PCB/Kit

- Buttons

Support my work

For non-Prusa parts and filaments, check out 3DJake ( International , UK , Germany , France ). I'll get a small cut of any order you fulfil using these links (at no additional cost for you 😉).

If you want to support my work directly, you can buy me a coffee .

If you want to order a Prusa printer and earn some Prusameters (I will also get some), you can use my referral code " @Whity " at checkout or click one of the following links (the code only works for the first order of each printer model): | CORE One | CORE One Kit | MK4 | MK4 Kit | MINI+ | MINI+ Kit | XL | SL1S | SL1S+CW1S |

18.06.2021:

- The code is available at GitHub now (removed the .ino file from downloads)

- Implemented WiFiManager

- Splitted the code into multiple files and separated the configuration

- It's now possible to show the temperature of a given location in a predefined Interval

- Shows the status of the clock during startup

- It's able to display different characters now if needed (for upcoming features i don't know yet)

- Various small cleanups and improvements

Print instructions

The printer needs to be able to print at lease 240mm and therefore will not fit onto the MINI, I'm sorry.
