Back to the Future - Delorean clock

thingiverse

<b>Intro</b>: First and foremost, I'd like to extend my gratitude to @jeje95 for his outstanding project. His design was just too large for my Ultimaker 3 printer, so I decided to create a remake with two parts. And thus, an idea was born! You'll find five files in total: 2X .stl files 2X .SLDPRT files 1X Delorean_clock_code.ino (Arduino code) This is my very first project that I've completed, and I had an absolute blast creating and building it. I learned a tremendous amount throughout this process, particularly with programming and the clock module. The Arduino community is truly an excellent resource for learning! The clock module did pose some challenges initially. I couldn't quite grasp why the time kept resetting to the "flashing-time" after a power cycle. (Don't worry, I've included the solution in the programming section.) <b>Buying</b>: Here's a list with links to the products I purchased: Note: Keep in mind that my display differs from jeje95's, as mine doesn't have a colon but instead uses a period.

The adapter I used has a 5V output with 1.5A. <b>Printing</b>: Print the base "BovenMiddenOnderV2" as you've positioned it on your desk. Make sure the bottom is facing downwards (I'm not sure why Thingverse included the file upside down). Next, print the back side "deksel". <b>Assembly</b> To assemble the clock, simply follow the Clock_Wiring instructions. If you're using a non-rechargeable battery like I did, be sure to adjust the Real Time Clock RTC accordingly. I used a glue gun for assembly. Remove R4, R5, R6, and D1. Create a jumper wire on the spot where R6 was (refer to the before-and-after pictures). If you don't do this, your nano will use the time from the flashing mode after a power cycle. <b>Programming</b> I primarily used jeje95's original programming with some adjustments of my own. The libraries I employed are: SevenSegmentTM1637 by bram harmsen RTClib by adafruit Wire by adafruit Neopixel <b>To do</b> - Add stickers to the front - Implement auto-adjust backlighting. The current setting seems too bright for evening use. - Investigate why the clock appears to be running a bit faster than normal time, resulting in a 3-minute discrepancy after 18 days
