Word Clock printable- Wortuhr

thingiverse

This is my budget-friendly take on the "word clock". This project offers an affordable, printable battery-powered alternative to existing versions. Size: 330mmx325mm Language: German Depending on your printer's capabilities, you can print the frame in one part or nine separate parts for a maximum bed size of 154mm X 120mm. After printing the individual parts, it is essential to smooth out the edges and assemble everything together using 2K epoxy. Before gluing, remember that all small components are designed without any fittings. Grind all edges and corners carefully, and inspect the finished piece. You may need to enlarge the laser-cutting files in this case, as plexi dimensions play a crucial role. The frame features a slot for three 9V block batteries. In my first version, I attempted to create a battery-powered clock. The electronic hardware is straightforward: -Arduino Nano -DS1302 real-time clock -2*50 prewired LED WS2812B (e.g., https://www.ebay.de/itm/50Pcs-WS2812B-Pre-wired-LED-Pixel-Module-String-Light-Full-Color-5050-RGB-5V-X1/253214148875?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649) The code I wrote can be easily modified to English by adjusting the classes and frame letters. I plan to do this in my free time. The code is included in the download files as a .ino-project. Currently, there is no power optimization, but it will be implemented soon. Wire-Configuration: RTC: -VCC -> +5V Arduino -GND->GND Arduino -CLK->Digital 5 Arduino -DAT/I-O->Digital 6 Arduino -RST/EN->Digital 4 Arduino WS2812B: -GND-> GND Arduino -VCC-> +5V Arduino -Data 1stripe -> Digital 7 Arduino -Data 2stripe -> Digital 8 Arduino To test the hardware, there is a Serial-Output @9600 refreshing every 30 seconds. It will display the current time @RTS, the calculated time in 12-hour mode @RTC, and the text-output. Example output: 11:50->11:50-> Es ist zehn vor zwoelf 13:45->1:45-> Es ist viertel vor zwei In Firmware V1, you need to adjust the current time in a setup line during the first run. Day adjustment is not necessary: * Time t(2017,12,18,13,45,50, Time::kMonday //2017, December 18th, 13:45:50, Monday * To test words on both stripes, uncomment the following line in the loop()-class: * //test_all(); * At least, there is a satin plexi front-plate and a wooden backcover that you need to fabricate using a lasercutter or by hand. Simply round off the corners and cut some rectangles. If possible, use a lasercutter, as PDF-files are included. I recommend using black filament due to light absorbance or painting it black in several layers.
