Binary Led Clock (24h)

thingiverse

This is a next 3D printed case for an LED clock. The version you see here is a binary LED clock. I have to admit that I was inspired by many creations found online and decided to create my own. My previous LED clock was designed in SketchUp, but this one was fully created using OpenSCAD so I could learn the tool. To be honest, I was surprised at how quickly I could produce results. As you can see, my creation is simply a box, but I'm still impressed by what imagination and coding techniques can achieve. I hope that people will find pleasure in this project. I'm currently working on a case for the NodeMCU (ESP8266). It's not finished yet. The clock is lit up using 18 RGB LEDs from AliExpress, which are 60 LEDs per meter long and have WS2812B and IP30 ratings since I plan to use them indoors only. Here's a sample link to the LEDs on AliExpress: https://www.aliexpress.com/item/1m-4m-5m-WS2812B-Smart-led-pixel-strip-Black-White-PCB-30-60-144-leds-m/2036819167.html?spm=a2g0s.11045068.rcmd404.2.76fd56a4XC72uJ&scm=1007.16891.101496.0&scm_id=1007.16891.101496.0&scm-url=1007.16891.101496.0&pvid=0a257068-7fd7-4e5e-9e97-42c2f72efddc&_t=pvid:0a257068-7fd7-4e5e-9e97-42c2f72efddc,scm-url:1007.16891.101496.0 The LEDs are connected in a single strip to allow only three wires coming out of the case. This makes it easy to think about using a full-size Arduino with an ESP8266 or NodeMCU (ESP8266) or even a small ESP-01. Since I designed the case for a CTC Bizzer, I didn't go too big and planned to have the control board on the outside. The software is not yet finished, but I might plan to add a LDR Photoresistor to dim/un-dim during day and night or to control it through a web GUI hosted on the ESP8266 itself. Or maybe any other add-on like a power switch. By the way, would anyone want to turn off such an LED clock once it's lit up? 2018-05-31: I added the current .ino Arduino code, feel free to use or modify it.
